A Nice Warm-up For The Weekend
Springfield (WICS) - After the seasonably chilly weather the past few days, central Illinois will undergo a nice rebound with the temperatures just in time for the weekend. High pressure will settle into the Ohio River Valley bringing a warm southerly wind up across Illinois, and temperatures will respond by climbing easily into the 40s for both Saturday and Sunday.
A few weak weather disturbances will drift through the Great Lakes over the next day or so only to bring periodic clouds into central Illinois and a little dusting of snowfall across northern Illinois, especially north of I-80, otherwise the weekend should be dry featuring a mix of sun and clouds.
By late Sunday into Monday another low pressure system will march across the Great Lakes dragging a cold front with it, and this weather system promises to trigger a light wintry mix switching to light snow on Monday as highs struggle into the low 30s. Leftover snow flurries are still possible for early Tuesday as well before the precipitation comes to an end with only minor accumulations expected.
In the wake of this system, look for much colder Arctic air to make an appearance. Highs on Tuesday will only top out in the low 20s and remain in the mid to upper 20s on Wednesday while evening lows will plunge into the low teens causing wind chills to plummet into the sub-zero category. Luckily this Arctic cold snap will be brief in duration with moderating temperatures expected by next Thursday and Friday.

THE 7-DAY TEMPERATURE OUTLOOK: Look for highs in the upper 30s Friday; mid to upper 40s Saturday and Sunday; low 30s Monday; low to mid 20s Tuesday and Wednesday; and, mid 30s Thursday. Overnight lows will fall to around 30 Friday through Sunday night; low to mid teens Monday and Tuesday night; and, upper teens Wednesday night.
