Thur-Fri, May 14-15th Flood Threat Short Term Update

(10:45PM - 5/14/20) As expected, several rounds of rain and t'storms are affecting portions of the state, associated with a storm system moving through the region.

A few rounds of rain and t'storms moved across Northern and  Central Illinois, from late last night morning and into early this afternoon. The hardest hit areas were north of I-88 in Northern Illinois, where upwards of 1.00-2.50" of rain occurred. Elsewhere rainfall amounts were much less across the rest of Northern Illinois and Central Illinois, generally 0.25-1.25". 

This evening into early tonight, several other areas of rain and t'storm have been moving across Northern and Central Illinois. One of the clusters produced upwards of 2.00-5.00" of rainfall in a corridor from around Pontiac to Kankakee over a couple hour period. Large clusters of rain and t'storms will continue to spread across Northern and central Illinois throughout tonight, with additional heavy rainfall and flood potential expected. When combining all rounds of rainfall for the event, a few corridors with rainfall totals upwards of 3.00-6.00"+ are likely, with more general amounts of 0.50-2.00" outside of the hardest hit corridors.
