A deepening area of low pressure will track from the Plains into the western Great Lakes today, pulling a strong cold front toward central Illinois. Ahead of the front, windy and very warm conditions will prevail, with temperatures soaring well into the 80s. As the cold front approaches from the west, strong to severe thunderstorms will develop across Iowa and northern Missouri very late in the afternoon, then will push into the Illinois River Valley during the evening.
The Storm Prediction Center (SPC) has indicated that a SLIGHT RISK for severe weather exsists across all of central and southeast Illinois through tonight. At this time, it appears large hail and damaging winds will be the primary threat across the area. However, a few tornadoes will also be possible, mainly along and northwest of the Illinois river, as the storms track into west-central Illinois this evening. The storms may tend to weaken as they move into east-central and southeast Illinois toward midnight; however, large hail and damaging wind gusts will still remain a threat into the overnight hours. Stay tuned to later forecasts for updates on this potentially significant weather event.
