Clouds cleared out early today but have returned as a band of high clouds filters through the region behind our cold front that is giving us a shot of cooler, drier air. These clouds will depart through the evening leaving us with clear skies and a chilly night.
Another dry cold front will work through on Thursday, and behind this front, colder air will pour in from the north as a strong area of high pressure will set up shop Friday into the weekend. Underneath this Canadian high will be the coldest mornings so far with lows getting below 36 degrees for just about all of us Saturday morning. This is enough to cause frost to form in many locations.
The coldest air with this system looks like it will pass to our northeast, meaning we begin a fairly rapid warm up as an upper level ridge arrives for the start of next week which will send temperatures back into the mid 70s.
Since this we are looking at our potential for our first frost, below are first freeze and frost dates for locations in the area from the National Weather Service in Jackson. From our climatic averages, we are right on schedule to have our first frost:

First Freeze (temperature at or below 32 degrees):
