Through Wednesday night…
A large area of high pressure is keeping the weather nice and quiet today aside from some cold. Temperatures across the area early this afternoon vary from the lower single digits to mid teens. Winds have picked up slightly over the past several hours now moving at around 5 to 10 mph sustained. With temperatures this cold, that`s enough to pull wind chills down into the single digits below zero. While it may not feel the greatest outside, it certainly looks nice with a mostly dry profile bringing about mostly sunny skies. We`re in for another awfully cold night ahead, albeit not quite as cold as it was this morning. As the high, currently centered over the IL/IA/MO tripoint, progresses eastward through the rest of Tuesday and Tuesday/Wednesday overnight, modest warm advection will take place in the mild return flow. In fact, most high-res guidance is showing temperatures bottoming out during the middle of the night before we flatline or possibly even warm slightly into the early morning. We`re looking at lows back in the single digits below zero Wednesday morning mainly for areas north of I-80 and west of I-355. Elsewhere, expect single digits above zero. Light winds will pull wind chills down to 15 to 20 degrees below zero across the aforementioned cooler areas. Continued warm advection through the low levels will cause temperatures to steadily rise through the day tomorrow. Highs are expected in the mid 20s to near 30 degrees. The sunshine will stick with us through tomorrow as well. Temperatures tomorrow night are forecast to drop into the middle and upper teens, though wind chills will likely be back in the single digits.
