SUN 'n FUN was a blast (literally)!

EZWxBrief in the Innovation Showcase

We are really excited about being chosen this year to participate as an exhibitor in the inaugural Innovation Showcase. This was held at the 50th annual SUN 'n FUN event in Lakeland, Florida. This means that EZWxBrief was highlighted as a product that has contributed to safety within the aviation community for its unique and innovative approach to preflight planning.

The weather was outstanding just about every day of the event, but we did get to experience severe convection rolling through the Lakeland area ahead of a strong cold front on Thursday afternoon. A line of severe storms dropped heavy rain and blasted the event grounds with strong, gusty straight-line winds. Unfortunately, the downpour of rain over a two hour period flooded the Innovation Showcase tent and the strong winds weakened one of the walls. The water also knocked out power to our booth. Nevertheless, power was restored the following day and we began to dry out a bit. Prior to the storms arriving, the EZWxBrief booth was a humming with attendees and other vendors wondering how bad it was supposed to get.

It was great to see a few of you there at the booth as we were demonstrating EZWxBrief v2.0 all week. Many of you also attended several of Scott's eight presentations during the event. If you missed us at SUN 'n FUN, we look forward to seeing you again in July at AirVenture in Oshkosh. More to come in a future EZNewsletter.

Termination of TAF for Troy, Alabama

The NWS is proposing termination of the Terminal Aerodrome Forecast (TAF) at Troy, Alabama (KTOI). Over the past several years, airport statistics show that aircraft operations per day are mainly from nearby Fort Novosel. The proposed termination date for KTOI TAF is June 25, 2024.

Canadian GFAs have been discontinued

On Tuesday, April 9, 2024. NavCanada no longer provides access to the GFA imagery. As a result Canadian GFAs have been removed from the static imagery in the app until a suitable replacement is found.

New static imagery added

If you visit the static weather imagery in EZWxBrief, you will notice new forecast guidance from the High Resolution Ensemble Forecast (HREF) model like the image shown below. This is a calibrated probability of at least one cloud-to-ground (CG) lightning strike within 12 miles of a point over the forecast period, in this case one hour. The forecast probabilities are calibrated to be statistically reliable based on CG lightning strikes recorded by the National Lightning Detection Network during the period from 2017-2019. Keep in mind this is a period of one hour such that it will be fairly rare for the probabilities to be 80% or greater even during extreme convective weather events. Also note that this is not a forecast for precipitation, but a forecast for convection. There will likely be areas of non-convective precipitation that is not represented by this forecast guidance.

EZWxBrief v2.0 update

Great news! We are targeting the release of EZWxBrief v2.0 for the end of May. Look for several emails and blog posts to be sent in the next three weeks that will announce the availability of EZWxBrief v2.0. This will include release notes and instructions on how to migrate to this new version. Moreover, during the time the new version is released, EZWxBrief will be taken down for several hours and will be unavailable.

There have been a lot of changes that will address much of the feedback that we've received over the last three years. We look forward to hearing from you about your initial impressions of EZWxBrief v2.0! And we look forward to more innovation with your help and contributions in the coming years.

Most pilots are weatherwise, but some are otherwise™
