Tracking a chilly Friday with bitterly cold air this weekend

TONIGHT: Mostly cloudy and chilly with spotty light flurries or sprinkles. Lows in the upper 20s.

TOMORROW: Mostly cloudy and cold with highs in the upper 30s.

EXTENDED: Clouds are holding on this evening as a clipper system slides by to our east. Precipitation chances continue to look low, but we'll remain chilly tonight as temperatures drop into the upper 20s. Tomorrow will be cooler as winds shift to the northwest and keep temperatures in the 30s. Another clipper system slides in from the northwest on Saturday, bringing a shot at accumulating snow across northeast Missouri, Illinois, into Indiana. We could be clipped by the southern edge of this, with a dusting to 1" of snow stretching from about Macon to Mexico. A few light snow showers could stretch as far south as Columbia, but accumulation is not expected. Arctic high pressure takes hold for the rest of the weekend, clearing skies out on Saturday night and allowing lows to drop into the low single digits. Wind chills will likely fall to about -5 to -10 on Sunday morning, with highs only reaching the upper teens despite sunshine. Next week will bring a warming trend as highs get back into the upper 40s to near 50 by Tuesday.
