Showers and thunderstorms have had a very difficult time firing up across the Tennessee Valley this afternoon because the air is simply to dry.
There is a boundary that is sitting to our south, and its been acting as a solid barrier between widespread persistent rain and the couple of light showers we have seen in North Alabama.
Through the rest of the evening and into the overnight we can turn our attention away from that boundary and focus on the next cold front to come through the Tennessee Valley. That cold front will come early Wednesday morning, likely before sunrise. The rain will end behind the front, but the clouds could stick around through the lunch hour.
Behind the front are some much cooler temperatures. Highs tomorrow will only climb into the mid and upper 60s.
Winds will also be much stronger behind the front. Wind speed will increase almost immediately after the front passes and will be sustained at 15-20 mph through the entirety of Wednesday afternoon.
