More showers and thunderstorms are expected through this evening, resulting from a cold front marching east across the region and running into the humid air ahead of it. The storms will have the potential to produce damaging winds, large hail and locally heavy rain. Given the saturated soils, especially south of I-90, that rain could turn into flash flooding. Drier air will filter in behind the front tonight, effectively ending the flash flood concern. River flooding, however, will continue on rivers south of I-90 as water from recent rain flows into them.
More Severe Weather Possible Late Today & Tonight
Periods of showers and thunderstorms will continue through tonight. Those late this afternoon into tonight are of particular concern, as they have potential to produce not only more additional heavy rainfall (thus resulting in more flooding) but also damaging winds. The exact placement of the storms late this afternoon into tonight is uncertain, and could end up anywhere between I-90 and I-80. A cooler and somewhat drier period looks to setup Thursday and persisting through the weekend, which will help with river levels.
