Sharply Colder, Big Changes in Store

A strong cold front that brought over 2.00" of rain and a rash of severe weather last night passed through the area just after 3 a.m. Temperatures have since dropped quickly this morning and we're currently at 45 with a gusty northwest wind making it feel like temperatures are in the 30s. With cloud cover hanging tough and surface cold air advection, temperatures will hold steady this morning with an afternoon high around 44. However, gusty north northwest winds will make it feel like temperatures are in the 30s all day.

Rain will quickly return late tonight as the main upper air disturbance associated with this system moves our direction. At the same time, a jet streak will combine with the upper air disturbance to promote cyclogenesis in the Florida Panhandle tonight. This will be a big player for us because it will pull colder air down on the backside of the low. Temperatures will begin to drop late this evening to near 40. Forecast soundings show the precipitation should remain ALL rain tonight through sunrise tomorrow morning. In fact, the temperature tomorrow morning will be around 38 with a cold rain falling for your morning commute to work or school.

I'll have another update detailing the prospects for winter weather later. As a heads up, the NWS has issued a winter storm watch for our area tomorrow. More on that later!
