Wednesday Forecast: Changes To Come

Happy Hump Day! Patchy fog is being seen across the valley this morning, so take a little extra time on your way to work and school. As it lifts mid-morning, sunny skies will once again return with high's in the mid to upper 70's. A high pressure system stays overhead providing plenty of dry and warm air today and tomorrow. In fact, high's will be nearly 10 degrees above average Thursday with high's topping out in the low 80's for some. 

By Thursday night, a sharp cold front will find its way through the Tennessee valley. Check out temperature differences Thursday evening, a 10 to 15 degree difference on either side of the front. Most will be lucky to see high's in the 60's Friday afternoon with the coldest air we've seen so far this season and cloudy skies likely much of the day. Something I would like to highlight is the potential for FROST Saturday morning. Overnight low's Friday will be be in the mid 30's range, where frost could be an issue. As we get closer to time, we will have a better understanding of how quick cloud cover will move out (a very important role in how cool things get). As a precaution, plan for patchy frost in some areas Friday night and we'll have more details as this front draws closer.

In addition to much cooler air, scattered showers are also likely late Thursday and through the first half of Friday. The majority of showers will hang to the north but don't be surprised to pick up a few hundreds of an inch through the day. Following the front, and associated showers, a high will build in bringing more sunshine for the weekend. Things will begin to work back towards average with high's in the upper 60's to low 70's Sunday and Monday. 

Temperatures will continue to warm today and tomorrow but if you are a fan of the cold, good news is on the way. For now, enjoy the sunshine and mild temperatures.
