March may mark the beginning of meteorological spring, but with close to half a foot of snow expected in some places this weekend, winter is beginning to resemble a guest that doesn't know when to leave.
Today's snow storm, which prompted a winter weather advisory from the National Weather Service, arrived this afternoon.
Areas across the region will see about 2 to 5 inches of snowfall, with most areas under 4 inches, the weather service said in short-term forecast issued this evening. A winter weather advisory remains in effect until 9 a.m. Sunday.
Snow was still falling throughout northern Illinois, and was expected to taper off in most of the area, with snow persisting through midnight in areas between Interstate 80 and Interstate 88.
As of midnight, 3.1 inches had fallen at O'Hare International Airport since the afternoon, according to the weather service. Rockford had 3.4 inches during the same period, while 1.4 inches fell in Romeoville.
Another inch or so was expected to fall in the city before daybreak. Intermittent now showers are expected during the day Sunday, although accumulation in the city is projected to be only few tenths of an inch. Areas in Kankakee and Will counties could see more significant snowfall on Sunday, bringing their weekend accumulation totals to as many as 7 inches.
An extensive low pressure system is moving up the Ohio River Valley through Kentucky. A winter storm watch has been posted for central and southern Illinois and Indiana, warning of of 6 to 10 inches from the Bloomington south and a band of freezing rain and sleet and snow south of Interstate 70 downstate.
The question is how much snow will fall between Bloomington and Chicago.
The highs will only get into the 20s over the weekend, then dip into the teens Monday and Tuesday. There's a chance we could reach the freezing mark by Thursday.
The meteorological winter, which runs from December to February, is going down in the books as the third-coldest and third-snowiest winter on record. There hasn’t been one worse since 1978-79.
