Cold but dry weekend in the Stateline while winter storm churns to South

 Despite some afternoon sunshine, temperatures struggled to reach the mid-20s, only topping out at 25° for Rockford's high temperature. Overnight, those numbers will remain cold, reaching an overnight low around 8°.

Temperatures will drop through the teens into the single digits, but wind chills will make it feel colder, down below zero for much of the night. While temperatures will return to the low 20s tomorrow afternoon, wind chills will only reach the upper single digits and low teens.

The Stateline will likely remain dry throughout the entire weekend, but a major winter storm is taking aim at the Ohio River Valley Sunday into Monday. Snowfall could start Sunday morning across Southern Illinois, Southern Indiana, and Kentucky. South of the heaviest snowfall axis, sleet and freezing rain may be possible.

Winter storm headlines stretch from Kansas to Virgina, where the highest confidence of winter weather impacts lie. Generally speaking, anywhere underneath a winter storm watch or warning can expect around 6" of snowfall and/or impacts from ice accumulation (like in Kentucky). 

There will be a sharp gradient on the Northern edge of the snowfall, with lots of dry air to the North eating into totals. Barring a major shift Northward, only areas near I-80 have a chance for accumulating snowfall aside from any lake-effect closer to Chicago.

Temperatures will remain chilly through the weekend and beyond, with highs below freezing and below average all through the week ahead. Monday and Tuesday will be the "warmest" with highs in the mid to upper 20s, but another push of colder air arrives for the second half of the week. Overnight lows during this time will be in the teens to single digits.
