Weather Blog Surface Forecast Valid 1 PM Tomorrow and last updated 2021-04-07 09:27:06-04 Good morning bloggers, We were predicting a very low chance of any severe weather last night, and there was no severe weather in our region. We did get a few bands of showers and thunderstorms between 3 AM and 7 AM. These bands of rain have shifted east and fallen apart. A strong storm is forming overhead and look where the center of this storm is forecast to be around 18,000 feet above us tonight: 500 mb Flow Forecast 1 AM Tonight Look closely at the closed circles, two of them, right over Kansas City. This is a forecast for tonight at just after midnight showing the 500 mb level. The top of the atmosphere weighs nothing, and the weight of the atmosphere at the surface is around 1,000 mb. MB stands for milibar, which is a measure of atmopsheric pressure, or a measure of the weight of the atmosphere above us. The 500 mb level is half way through the atmosphere in weight, and around 18,000 feet up. This is the level we look at to find the cycling pattern and the storm systems.
