Besides Saturday when a cold front moves through the region, there will be a general warming trend into early next week to well above normal. There will be just a few minor precipitation chances this period with flurries and light snow across northwest Illinois today, then a wintry mix possible across portions of northwest Illinois Friday morning.
A passing clipper system may produce a wintry mix of patchy light freezing rain, freezing drizzle, and light snow late tonight into Friday morning. The main areas of concern are across northwest Illinois into extreme northeast Iowa. This wintry mix may produce a light glaze of ice on travel surfaces producing some slick spots, affecting the Friday morning commute.
Taking a look back at January, temperatures started out warm for the first 2 weeks then turned much colder for the rest of the month. Most of the precipitation fell on January 8th, with monthly totals a quarter to an inch below normal. Snowfall also was below normal for the month.
