The weather situation is complex over the southeastern U.S. today, and it's time to start moving away from computer models and looking out the window. The surface map above shows a dry line, or a front that causes a wind shift and brings in drier air, moving through eastern Mississippi... Continue reading

A strong cold front is moving through the Midwest this afternoon, and the weaker end of it will move through Alabama tomorrow. It is getting late enough in the year where the coldest air often doesn't go this far south. But, the tail end of the front and its dynamics... Continue reading

You hear us talk about wind shear and helicity, and its effect on storms and their rotation quite a bit. This is a quick blog to explain what these are and how they operate. 1. Wind shear Wind shear is simply a change in wind speed or direction with height.... Continue reading
