This app makes the others seem like they're for children. Need an example? At the bottom right touch the circle cross, uncheck all data except Humidity, check Save, with two fingers pan to the Pacific ocean, widen fingers to zoom out, place your thumb lightly on the left side of the screen, slowly slide it to the right...THAT is what Humidity looks like when it's roiling around in the atmosphere!!! it's just amazing
Great model visualization & easy to use

My husband is a pilot and finds this app useful for getting a quick look at forecasts of all of the weather points pilots are concerned with. I’m just an enthusiast who enjoys keeping an eye on wind, rain, and temperature conditions. I’m getting in the habit of checking the app daily. Love the visual forecasts and how easy it is to navigate.
The best big picture Weather App out there!

Love his app! Gives you a big picture outlook on weather impacts over the next week. As a pilot I use this app to see where the significant operational disruptions may occur as I crisscross the country over the next few days.
Best App for Storm Predicting
Anime dragon
I live in Oklahoma where Storm predicting is a necessity. This app gives you the tools to use the same weather models that the professionals use. You are able to utilize these models to see what weather will be in your area days in advance.
