Good evening Tennessee Valley, and a very happy Wednesday! Sunny skies once again this afternoon, but that still didn’t help temperatures warm up with the official high at HSV coming in at 40 degrees. Keep in mind 40 is the average low temperature with the average high temperature sitting at 62.
We’re in store for another cold night as conditions will remain clear across the Tennessee Valley. A freeze warning is once again in effect for the entire area until 8:00 AM Thursday morning.
Everything begins to change tomorrow with a change in the direction of our upper level winds. They’ll become more southerly through the course of the afternoon and that’ll help warm things up into the mid-50s. Still below average, but at least it’ll be warm and still with a fair amount of sunshine. Clouds will be on the increase especially as we get into the late afternoon and early evening ahead of our next system.
Our next system comes in the form of an upper level trough that will continue to march east through the day Friday further enhancing the southerly flow across the Tennessee Valley. Rain showers will begin to move in Thursday night and will continue through much of the day Friday. This will not be a widespread event, and I expect the activity to remain rather scattered with brief breaks in the rain.
Our real soaker and a chance for thunderstorms will come on Saturday as the same system lifts NE bringing a warm front north through the Tennessee Valley. This should help provide the needed fuel for a few thunderstorms and some more widespread rain Saturday evening and then through the overnight.
As the low begins to push east across the Great Lakes expect a cold front to move through the Tennessee Valley early Sunday morning. Unlike the last cold front I do not expect a drastic drop in temperatures and we’ll spend Sunday and the majority of next week in the low 60s.
