I've always liked getting forecast SkewTs using your grid map since your interface for that is about the best around in my opinion. I pulled in some of your model fields via AllisonHouse and overlaid them in GRLevel2. I hadn't done that before, I like that feature. I plan to use F5 more this year to take advantage of everything you offer. I think I was missing out on so many things you have available in your software.

The watch and warning features worked flawlessly. Between MTN [Mobile Threat Net], GRLevel 3 and F5, it certainly made my life easier. I DID catch the FTW storm! Just wanted to let you know that I am AMAZED how accurate your F5 data tornado and severe parameters have panned out. I think you have a winner with F5 and the parameters you developed for your severe weather forecasting are outstanding!

I frequently use the F5 program for Skew-T data for inversion (temperature) information and wind speed and direction through the lower levels for daily forecasting. I like the layout of the new program and it is very helpful and I especially like the resolution. I like the ease of use and available information the program provides.

Well conceived and eminently useful, the new, upgraded F5 Data is a tremendous resource for storm chasers, weather buffs, meteorologists, and anyone with an interest in the atmosphere. It’s as close as I’ve found to a one-stop weather tool, and the price of a subscription is very reasonable.

Since I first subscribed to it back in 2007, F5 Data has been first in my lineup of forecasting resources. It offers a staggering amount of information, including proprietary indices you can't find anywhere else. When storms are firing, the ability to overlay F5 RUC maps on GRLevelX radar products via Allisonhouse helps me quickly determine what kind of environment a storm is moving into. Last, but very importantly, F5 developer Andy Revering provides topnotch customer care, and is constantly striving to improve his already exceptional product. I recommend F5 Data highly. Try it for yourself and find out why. At fifteen bucks a month, the only risk you run is becoming addicted.
