Springtime is a time of transition and Central Illinois gets a wide range of weather to choose from the next few days!
A cold front pushes into mid-Illinois Tuesday and will play a large role in temperatures across the area. Our northern most counties closer to I-74 will only warm-up to the mid- to upper 50's while the rest of the area easily reaches in the lower to mid- 60's -- in fact, our southern most counties closer to I-70 could see thermometers topping out in the upper 60's!
Clouds will also be increasing as the front passes through central Illinois into the afternoon. Once the front settles just to the south, low pressure will lift out of the southern plains and slide northeastward along the frontal boundary as a wintry mix of precipitation develops Tuesday night. Rain -- and possibly some isolated thunderstorms -- will gradually change over to snow as colder temperatures build back in overnight. While our southern most counties will likely see rain with only a little bit of snow mixed in at times, locations along and north of I-72 --including Springfield, Jacksonville and Decatur -- will pick up 2 to 4" of slushy snow accumulation by Wednesday morning and locations closer to I-74 could pick upwards of 3 to 5" of the slushy snow.
As this latest weather maker works its way through the region, strong winds will also develop with gusts at times up to between 35 and 45 mph after Midnight early Wednesday morning and will continue to be rather brisk through Wednesday afternoon. With the snow expected to be wet and slushy, blowing and drifting snow shouldn't be a travel issue -- despite the strong, gusty winds.
After a very cold night Wednesday night with lows plunging into the teens and 20's, any accumulating snow won't stick around long with sunshine and warmer temperatures quickly returning to most of the area Thursday. Although parts of eastern Illinois will struggle to reach 40 degrees, most of mid-Illinois can expect highs into the upper 40's and lower 50's Thursday afternoon. Temperatures will continue to warm-up Friday and Saturday before another disturbance brings rain chances Sunday and a return to colder temperatures into the start of the upcoming week.
THE 7-DAY TEMPERATURE OUTLOOK: Look for high temperatures in the upper 60's Tuesday; lower 30's Wednesday; near 50 Thursday; upper 50's Friday; mid- 50's Saturday; mid- 40's Sunday; and, lower 40's Monday. Overnight lows will fall to near 30 Tuesday night; upper teens Wednesday night; mid- 30's Thursday and Friday night; lower 30's Saturday night; and, mid- 20's Sunday night.
