We spent most of our Wednesday in the 40s, running 5-10 degrees colder than normal for the high temperatures. Another cold front is on the way. It is north of us tonight, stretching from the eastern Great Lakes through Ohio, Indiana, and Illinois to Iowa and South Dakota. That cold front is our next weather maker. It will sneak quietly through the Tennessee Valley tomorrow afternoon. It will not bring any rain, but it will make us even colder than we already are. High temperatures ahead of that cold front were in the upper 40s from Huntsville to St. Louis today. Behind the cold front, high temperatures were in the 20s and 30s from Chicago to Fargo.
Remember dressing in layers will keep you warmer more effectively than one heavy coat. Also remember to drink plenty of water. As tempting as it is to drink warm drinks like coffee and hot chocolate, the body can become dehyrated more quickly in cold air. Also be safe keeping warm indoors. Space heaters need at least three feet of space all the way around them. Make sure there's nothing flamable near fires, too. Never use stoves or ovens to keep warm.
That colder air will slide into the Tennessee Valley behind that cold front. We will notice it starting Thursday night and Friday morning when temperatures drop into the 20s. Friday afternoon will struggle to warm into the upper 30s, then highs climb through the 40s this weekend. Morning lows will slowly warm through cold 20s.
This evening will be mostly cloudy with some clear spots. Temperatures will drop slowly through the 40s. Overnight will be mostly cloudy. The low by morning will be near 36 degrees. Tomorrow morning will be mostly cloudy with mid-to-upper 30s. The high will be near 50 degrees.
