... Springlike most areas again on Tuesday... then back to winter late Tuesday night into Wednesday...
One more mild day is expected on Tuesday with afternoon temperatures forecast to climb to around 70 over parts of west central through southeast Illinois. However... this will be the last of the warm ones for a while as storm develops to our west late Tuesday afternoon and begins to affect the area Tuesday evening through Wednesday.
Rain and a few thunderstorms will develop over parts of central through east central Missouri by Tuesday evening and track across parts of south central Illinois... while further north... a steady rain will develop from southwest to northeast. Rain is then forecast to gradually change over to snow late Tuesday evening... and especially during the early morning hours of Wednesday. By the time the snow ends late Wednesday morning over the east... accumulations of snow will range from 2 to 5 inches... with locally higher totals east of Interstate 55. The more concentrated band of snow will be along and east of a Peoria to Lincoln line. A few locations may see a mix with sleet just before the changeover to snow occurs late at night. Northeast to north winds are expected to increase to between 20 and 30 mph with gusts around 35 mph at times. At this time... it appears the snow will be rather slushy as temperatures will be around the freezing mark late Tuesday night before falling off by dawn Wednesday when the snow is expected to be diminishing... so the threat for widespread blowing and drifting snow appears low at this time.
Most of the accumulating snows should push east of our area by late Wednesday morning... followed by colder weather for the rest of the day. If you have travel plans anywhere across the Midwest over the next couple of days... keep track of the later forecasts on this developing storm system. Any shift in the track further north or south for later Tuesday night into Wednesday will have a dramatic affect on precipitation type and amounts in our area.
