I just saw this today... it's pretty cool! It is based on a reputable forecasting computer model called the GFS (Global Forecast System). One of many models that meteorologists use in forecasting weather. https://www.windyty.com/?surface,wind,2015-02-15-15,22.857,-84.902,5 You can change altitudes, etc... Notice how the wind shifts on Monday bringing moisture up from the gulf. Rain is predicted for Tuesday... http://www.weather.com/weather/tenday/l/USFL0399:1:US Jim
