Apple iOS GPS Issue Resolved with 8.4 Update

UPDATE 7/2/15:

We have completed our general ForeFlight Mobile compatibility testing of the public version of Apple iOS 8.4. We recommend caution when it comes to any iOS update, however our testing did not reveal any significant issues.

###

We are happy to report that the GPS accessory compatibility issue that resulted from the Apple iOS 8.3 update is resolved with the iOS 8.4 update released this morning. We have performed a quality review of the Bad Elf GPS Pro, Bad Elf GPS Pro+, Dual XGPS150, and Dual XGPS160 on a Wi-Fi iPad running iOS 8.4 and these devices perform as expected. Stratus 1 and Stratus 2 devices were not affected by this issue. We have also started our general ForeFlight Mobile compatibility testing of the final version of iOS 8.4.

Customers that wish to resume use of their affected GPS accessories can upgrade to iOS 8.4. Customers that do not need immediate access to the affected GPS accessories can opt to wait until ForeFlight completes its compatibility testing of the final iOS 8.4 release and issues an ‘all clear’ notice.

For your reference, here are the instructions on how to update the iOS software on your iPhone, iPad, and iPod touch.

What’s Up With QPF?

Areas of precipitation that are forecast along your proposed route should get your attention. These should be considered “hot spots” for concern and may add undo risk to the flight. While precipitation isn’t always problematic, even to pilots flying under visual flight rules (VFR), adverse weather elements such as thunderstorms, low IFR conditions, mountain obscuration, reduced visibility, airframe icing and turbulence tend to occur in and around areas of precipitation. So these precipitation areas are regions that pilots need to drill down a little deeper to determine what, if any, impact they may create on their planned flight.

This is the reason we introduced the 6 hour Quantitative Precipitation Forecast, or QPF, in ForeFlight Mobile 7.1. Shown below, the QPF represents excellent guidance when planning a cross country trip, whether your flight is several hours or several days in the future. You can find the 6 hour QPF under the CONUS Weather in the USA Ensembles. So let’s take a look at the advantages and limitations of the QPF.

QPF Example

This is the 6 hour QPF or Quantitative Precipitation Forecast.

Most pilots are familiar with the precipitation forecast on Prog charts. Precipitation identified on prog charts such as the one shown below is considered an instantaneous precipitation forecast. That is, the precipitation shown is valid at a single time and represents precipitation coverage or where precipitation is expected to be reaching the surface at the valid time.

Prog Chart Precipitation

The Prog chart includes an instantaneous precipitation forecast valid at a single time as shown in the lower left.

Instead of a single time, the QPF is valid over a range of time. In other words, it is the quantity of precipitation expressed in inches that is expected to reach the surface over a specific period of time. In this case, the period is six hours so the forecast is called a 6 hour QPF. The valid range of time is shown in the date-time stamp on the lower left, so this forecast is valid from 0600 through 1200 UTC as shown below. It is important to note that unlike Prog charts, the QPF does not distinguish between the type of precipitation (rain, snow, freezing rain, etc.) nor does it tell you if the precipitation is the result of deep, moist convection or thunderstorms.

QPF-Date-Time-Stamp

Solid-filled color contours are drawn based on the expected precipitation amount (in inches) within the six hour forecast period using the scale in the lower left. Any “X” on the chart tells you the local maXimum precipitation amount (also in inches) within it’s respective contoured area. So for this forecast below in eastern Oklahoma and Texas, a maximum of 1.78” of precipitation is anticipated to reach the surface between the period beginning at 1800 UTC through 0000 UTC. In the case of wintry precipitation such as snow or ice pellets, the forecast roughly approximates the melted equivalent. Typically 12 inches of snow melted down represents about 1 inch of rain.

QPF

Also, the QPF doesn’t specify when the precipitation is expected within the valid range of time; it could fall all in the first hour, all in the last hour or it could be a continuous light rain falling throughout the entire forecast period. This is especially important to understand when the precipitation may be from convection. Often during the warm season, most of the precipitation forecast may fall within an hour or two and that could be near the beginning or end of the forecast period leaving much of the valid time free of precipitation.

The QPF offers a couple of distinct advantages over the instantaneous precipitation forecasts found on the Prog charts. Given that precipitation forecasts on prog charts represent coverage and are valid at a single time, the QPF can highlight areas of precipitation that may occur between Prog chart forecasts. For example, it is possible that an area of showers and thunderstorms may be expected to develop at 1900 UTC and dissipate by 2300 UTC. This area of precipitation would not be shown on the prog charts valid at 1800 and 0000 UTC, however, it would show up on the QPF. So the QPF is a complementary forecast to help fill in the gap in between prog chart forecasts.

Another advantage is that Instantaneous precipitation shown on prog charts stops after 48 hours. However, given that the QPF is valid over a range of time which is considerably less difficult to forecast, they provide guidance out to 3.5 days in the future – perfect for those Friday to Sunday round-robin flights.

PoP Goes The Forecast

When we make a decision to depart on any round-robin flight, it’s not unusual to also factor in the expected weather on the return trip. If the return leg doesn’t look very good, what’s the sense in making a flight that may put us in a compromising position later on. But if that flight is three or more days in the future, how do you know that it’ll be safe to fly back home? That’s a difficult question to answer because at three days and beyond there really isn’t any aviation-specific weather guidance that can tell you about adverse weather elements such as low ceilings and/or low visibility, airframe icing and turbulence. That certainly leaves pilots to fend for themselves.

If you want to stack the deck in your favor and choose the best time to minimize your exposure to adverse weather you should focus in on areas of precipitation. Of course, not all precipitation events are considered hazardous, but many are, especially when flying VFR. That’s because adverse weather elements such as IFR conditions, icing, turbulence and thunderstorms tend to occur in and around areas of precipitation. So it’s a good bet that if you find yourself faced with precipitation forecast along your proposed route, you will likely encounter some form of challenging weather, even if your planned flight is several days from now.

So that’s why in ForeFlight Mobile 7.1 we introduced the 12 hour Probability of Precipitation forecast like the one shown below. It’s known as the PoP forecast and you’ll find it in the USA CONUS Imagery view under 12 HR PoP.

Probability of Precipitation forecast

This is the 12 hour Probability of Precipitation (PoP) forecast. You can find this on ForeFlight under the Imagery view in the 12 HR PoP collection.

This forecast is issued by meteorologists at the Weather Prediction Center (WPC) in College Park, Maryland. It’s the same group of forecasters that issue the familiar prog charts pilots have used for many years. It’s designed to show the forecaster’s confidence of where precipitation will likely reach the surface within a 12 hour forecast period. The higher the numbers shown on the forecast, the higher the chances (probability) precipitation will occur in that period.

It’s important to understand the date-time stamp on the forecast. Many precipitation forecasts are valid over a period of time. In this case, the period is 12 hours. The valid time in the lower left of the chart is the ending time of the 12 hour period. In this case the forecast is valid from 12Z on June 1st through 00Z on June 2nd. This basically covers the daytime hours on June 1st.

While the short-range surface prog charts generally cover the weather features and precipitation expected over the next two days, the 12 hour PoP forecast describes the medium- to long-range forecast. It starts with Day 3 (the day after tomorrow) and runs through Day 7 with 12 hour forecasts ending at 00Z (daytime) and 12 hour forecasts ending at 12Z (nighttime).

Let’s say you were planning a flight from Chicago to Atlanta during the day on June 1. Using the 12 hour PoP forecast above, there’s a good chance you’ll face challenging weather along that route. On the other hand, if you were flying from Chicago to Oklahoma City, the likelihood of any significant adverse weather is minimal.

That’s not to say that most of the significant weather may end up occurring during the late afternoon on that flight to Atlanta. So a morning flight may still be possible. But this forecast doesn’t provide that level of temporal resolution. Moreover, even though the flight to Oklahoma City looks promising, you could still face IFR conditions, icing (during the cold season), strong winds or the potential for turbulence. So you can’t become complacent.

Day 3 Prog Chart

Use the Day 3 Prog chart along with the 12 hour PoP.

In that light it’s useful to also look at the Day 3 prog chart shown above (Day 3 through Day 7 progs are now located in the Prog Charts collection). Forecasters don’t show areas of instantaneous precipitation on the Day 3 through Day 7 progs, but what you do notice is that most of the precipitation shown on the 12 hour PoP forecast is along and ahead of the stationary front that extends from the Eastern Shore of Maryland southwest to Houston, Texas. Therefore, much of this precipitation is associated with a large scale synoptic feature which means plenty of dynamic forcing and likely the reason the probabilities are so high.

Also notice that behind the front the precipitation chances decrease and become nearly zero through Illinois and Missouri. This is courtesy of a rather large area of high pressure seen on the Day 3 prog with an inverted ridge spilling down from Ontario, Canada into central Texas. Such a ridge promotes subsidence or sinking air. Air that is sinking tends to inhibit the formation of clouds and tends to keep the air stable. While you can’t rule out early morning radiation fog or some moderate thermal turbulence in the afternoon, the chances of any significant turbulence aloft is minimal under a ridge. Lastly, the pressure gradient (distance between isobars) is fairly large implying a low risk of strong and gusty winds.

Pilots have never really been all that skilled using long-range forecasts. That’s understandable since a pilot’s primary training mainly focused on making a go or stay decision moments before departure. Very little time is spent on how to analyze the weather more than 24 hours in advance. But these long-range forecasts can provide some valuable planning information especially if your timing is flexible. Or if it’s not flexible, a bad decision now might tempt you to fly when the weather is hazardous later on for your return trip. Here at ForeFlight we hope that the 12 hour PoP forecast will provide the guidance you need for that long-range flight planning.

Our Weather Imagery Has Blossomed

Browse the Imagery view in ForeFlight Mobile and you will notice big changes have taken place! In addition to some basic spring cleaning, we nearly doubled the number of collections in the USA Ensembles.

What are all these new charts?

Like anything else that’s new, it’ll take some time for you to fully benefit from all of the imagery we’ve added to the ForeFlight Mobile app. We understand that some of these new charts may be unfamiliar to many customers. Therefore, in the weeks and months to come you can expect to see us offer more insight on how to effectively use this guidance in your day-to-day preflight planning regiment. So stay tuned to Twitter, Facebook, and the ForeFlight blog for more details.

12-hour Probability of Precipitation

Shown here is one of the new forecasts included in the USA imagery ensembles called the 12 HR Probability of Precipitation or 12 HR PoP for short.

What’s with the order of the collections?

Previously in ForeFlight Mobile, the USA collections were roughly ordered alphabetically with Alaska being first and Winds Aloft positioned last. With such a large number of new collections, we want to do a little better than to simply alphabetize the weather guidance. While there is no perfect way to order these collections to meet every pilot’s needs, we implemented an order that we think you will find useful. Here’s what we were thinking…

Picture a preflight weather briefing as a funnel with large-scale features at the top of the funnel and route-specific details at the bottom.  At the top of the funnel you start out with the synoptic overview (big picture) such as the location and movement of high and low pressure systems, fronts and associated areas of precipitation and clouds. The timing of your proposed round-robin flight is often critical, so we’ve placed outlooks and long-range forecasts near the top as well to help you decide which day may provide the best opportunity to minimize your exposure to adverse weather. As you work your way to the bottom of the funnel, this will include finer route-specific details such as en route advisories to include G-AIRMETs and SIGMETs, icing, turbulence, regional satellite, ground-based radar and last, but not least, pilot weather reports.

What happened to my favorite and recent images?

We made an honest attempt to preserve all of your favorite and recent images with this update. A careful mapping was done to point to the right image even for those that were moved from one collection to another. There were also a dozen or so images that existed in more than one collection; so we removed those duplicates. If your favorite image was the one we removed, it was mapped to the other location. Nevertheless, there may be a few images that were deleted and a few favorites or recents that were not preserved. If you are having trouble finding one of those images, please e-mail us at team@foreflight.com and we are happy to track those down.

Speaking of recents and favorites, there is now a recents button for imagery on the iPad version of the app as shown below. Now you can view and swipe through all of your favorites and recents on your iPad or iPhone. These settings sync across your mobile devices. As always, don’t forget to check out the Pilot’s Guide to ForeFlight Mobile to learn more about the new imagery.

Apple iOS 8.4 Expected To Resolve GPS Accessory Compatibility Issue

As noted in a previous blog post and via a customer notice email, iOS 8.3 introduced an incompatibility with previous generation GPS accessories like the DUAL XGPS 150 and some Bad Elf devices. The issue was escalated to Apple by ForeFlight and Bad Elf and, based on PIREPs we have received, is expected to be resolved in the forthcoming iOS 8.4 update. This issue has frustrated many pilots who own Wi-Fi only iPads or GPS accessories, and we are glad relief is on the way.

Prog Charts Are Changing

Prog Charts Are Changing

The Prog Charts that pilots have been using for the last decade or two (pictured below) will be undergoing a facelift sometime in September 2015.

Old-Progs

So at ForeFlight we’re giving you the opportunity to test drive the new charts before they become operational and are officially released by the National Weather Service (NWS). We’ve added these forecasts to our USA Ensemble Imagery and you can find them under the NDFD Progs collection as shown below.

NDFD-Progs

So What’s Changing?

The current Prog Charts are issued by highly experienced meteorologists at the Weather Prediction Center (WPC) in College Park, Maryland; that won’t change. The new implementation will still use the fronts and sea level pressure (SLP) forecast issued by those same meteorologists at the WPC, however, the precipitation forecast represented by those pale green lines is being replaced. The new instantaneous precipitation forecast is now being extracted from the National Digital Forecast Database (NDFD). Instead of the green contours, you’ll see the new precipitation forecast as shaded and outlined regions like the ones shown below.

New Prog chart

Example of the new NDFD Progs.

The new NDFD Prog Charts contain a mosaic of digital precipitation forecasts issued from all of the local NWS weather forecast offices (WFOs) throughout the United States working in collaboration with the National Center for Environmental Prediction (NCEP) and WPC. The forecasts depicted combine the familiar WPC forecasts of fronts, isobars and high and low pressure centers with the NDFD depiction of expected weather type and likelihood.

The precipitation presented on the new NDFD Progs is forecast coverage just like its legacy counterpart. So it is valid at the time posted on the chart and not over a period of time. Using a color-coding, the legend in the lower left corner of the image describes the precipitation type or weather expected (rain, snow, mixed, ice and thunderstorm) as well as the likelihood (chance versus likely) that the precipitation will occur.

Precipitation type legend

Definitions for the various weather types depicted on the NDFD Progs.

We know that it’ll take some time to become completely comfortable with the new forecast depiction of precipitation, but give them a try now so you’ll be way ahead of other pilots come September.

Flooding Rains In Texas Courtesy Of An MCS

Over the last five or more years a drought of historic proportion has plagued much of Texas. In fact, the National Weather Service reported that 2011 was Texas’ driest year on record. Fast forward to 2015 and that’s hardly been the case over the last few weeks as a good portion of Texas has received more rain in the month of May than they usually receive throughout the entire year. Rainfall totals reported to exceed 20 inches have been pretty common. And to cap it all off, this past Monday a very significant rainfall event occurred throughout central and eastern Texas with more than 10 inches falling in Houston Monday night causing widespread flash flooding in the city. So what caused this extreme rainfall event?

Texas Rainfall

Rainfall totals in May 2015 for the Southern Plains and lower Mississippi Valley. Image courtesy of The Weather Channel.

The phenomenon that was responsible for this deluge of rain on Monday is called a Mesoscale Convective System or MCS. Similar to hurricanes, they are very seasonal. Occurring mostly east of the Continental Divide, they start out in the Southern Plains and Deep South during the month of May. As the jet stream moves north through the summer months of June and July, they tend to occur in the Central Plains, Middle Mississippi Valley as well as the Tennessee and Ohio Valleys. Finally, into July and August, they are seen more in the Northern Plains, Upper Mississippi Valley and Upper Great Lakes regions.

These systems are usually severe and can often produce a few tornadoes, dangerous lightning, large and damaging hail and strong straight-line winds. But perhaps the most devastating feature is the torrential rains that can fall from some of these storms since they are often long-lived weather systems. Nevertheless, these convective systems are absolutely necessary since they provide much of the needed rain for agriculture in the Midwest during the summer months.

MCS on infrared satellite

Many Mesoscale Convective Systems (MCSs) have a signature oval or circular cloud shield as seen on the color-enhanced infrared satellite image. This is the one that provided Houston with over 10 inches of rainfall in just a few hours.

Mesoscale Convective Systems are easy to spot on the color-enhanced infrared satellite found in the ForeFlight Imagery as shown above. When mature, they usually appear as a large circular or oval cloud shield that can cover one or more Midwest states with very cold cloud tops that show up on this image as purple and white. Under this cloud shield is usually a bow-shaped line of strong thunderstorms at the leading edge of the MCS as seen on this NEXRAD mosaic below.

Bow echo associated with the MCS

Often an MCS will have a bow- or crescent-shaped line of echoes which is a good sign of very intense straight-line winds.

You were probably taught that the early morning hours are the best time to fly to avoid thunderstorms. That’s usually sound advice unless you are dealing with an MCS that will often develop and mature in the overnight hours and persist into the next day. So they are often nocturnal beasts that almost seem to create their own environment to feed on.

MCS Pair

The weather system that dumped a copious amount of rainfall on Houston Monday night developed from a pair of thunderstorm complexes in western Texas early that morning. It’s unusual to see a pair of Mesoscale Convective Systems tracking along together.

In fact, the MCS that flooded Houston Monday night was born early that morning in western Texas and began as a pair of MCSs as shown above. Throughout the morning the two systems tracked east and eventually merged (below) into a single complex of storms setting the stage for a very wet evening in Houston.

MCS combined

Just after 12 p.m., the pair of Mesoscale Convective Systems joined up in central Texas to produce one massive convective complex.

This is a very common setting in the Plains where the unique geography of the region favors nocturnal and early morning thunderstorms. During the warm season, this setting promotes a strong flow of low-level moisture northward from the Gulf of Mexico, often referred to by meteorologists as a low-level jet stream. Moisture carried by the low-level jet helps to maintain these systems that often begin during daytime hours on the higher terrain in western Texas and Colorado. Because of the low-level supply of moisture, the MCS can mature and persist well into the nighttime hours.

The Skew-T Log (p) diagram for Houston Monday evening shows the low-level jet as a maximum wind speed at 6,000 feet. This moist, southerly flow keeps the surface dewpoint temperature in the low 70s to offer a good source of moisture for the MCS to ingest.

Skew T Diagram

The Skew-T Log (p) Diagram is an excellent source to visualize the moisture, winds and the instability for a particular location.

Last but not least, the Skew-T diagram shows the atmosphere was very unstable Monday evening with a lifted index of -6, Convective Available Potential Energy (CAPE) approaching 3,000 Joules/kg and a K-Index of 42. A K-Index this high is a good sign of high convective rainfall rates that can produce local flash flooding.
