A flash flood watch continues for the Aurora area through 7 a.m. Friday morning. Conditions are right for another heavy rain event across portions of the area, with more intense lightning.
Heavy rains last night generally fell across the northern half of the area. Areas to the south were still able to witness the incredible lightning show. The National Weather Service in Chicago stated that over 68,000 cloud to ground lightning strikes occurred across eastern Iowa, southern Wisconsin, and northern Illinois last night. Northern portions of the area saw over an inch of rain, while areas along the Illinois Iowa border saw an incredible 10-15 inches of rain.
While the area was spared an historic flood, thunderstorms are firing yet again. The area continues to be stuck on the edge of a heat wave, sitting in the way of thunderstorms riding along the edge. Tremendous amounts of moisture remain in the atmosphere with dewpoints nearing 80 degrees. Thunderstorms are currently ongoing northeast of the area, but may back build to the southwest. There is the potential for storms to train west to east across the area and produce multiple inches of rain in spots.
The front should slide to the south tomorrow, finally giving the area relief from rain and humidity. Temperatures will remain in the upper 80’s. July will remain hot right to the end.
