As a frontal boundary remains draped across central Illinois today, temperatures will vary significantly. Areas south of a Danville to Macomb line will see highs in the 70s, while highs to the north of this line will be much cooler, as low as the 50s from Galesburg to Henry.
Showers and thunderstorms are expected to develop today in the unstable air across Missouri and Illinois, and push eastward as a cold front moves in from the west. Severe thunderstorms with damaging winds and large hail will be possible, mainly late this afternoon and evening, in areas mainly south of a Rushville to Bloomington to Danville line. In addition, isolated tornadoes cannot be ruled out, with areas east of I-55 most likely to see this occur. Heavy rain is also likely today with the storms.
