Flash Flooding Potential

Updated: 2019-09-21 23:48:54-04

***FLASH FLOOD WATCH FOR MILWAUKEE, WAUKESHA, JEFFERSON, RACINE, KENOSHA & WALWORTH COUNTIES THROUGH 1AM MONDAY***

A cold front is slowly moving through Wisconsin but before it sweeps through we have plenty of moisture moving in so a Flash Flood Watch is in effect through 1am on Monday for areas along and south of I-94. Showers will continue to stream into southeastern Wisconsin this evening and overnight with many locations picking up a quarter to a half an inch of rain possible overnight with a breezy southwest wind keeping temperatures mild in the upper 60s.

The heaviest rain will hit on Sunday morning with downpours and thunderstorms likely between 4am and 9am but showers area still likely through the rest of day. Repeated rainfall bringing another 1.0"-1.5" on Sunday will keep the chance for flash flooding, especially in areas close to Illinois where rainfall 8-10 days ago was in the 6-8" range. Highs on Sunday will be in the mid-70s with a southwest breeze eventually turning to the northwest as the cold front swings through to bring an end to the rain close to 10pm. Temperatures fall into the 50s Sunday night and into Monday morning with clearing skies falling as the day progresses. Monday will be cooler and less humid with highs barely making it into the 70s and not feeling quite like that due to a brisk northwest wind, quite the perfect weather for the official start of Fall.

Tuesday may start out with some patchy fog before the sunshine wins out with highs in the low 70s. A cold front moves in on Wednesday to bring a chance for showers with 70s for highs. It gets cooler behind the front with highs in the 60s on Thursday with more sunshine expected. Rain chances return for Friday and into next weekend.
