Heavy rain and flooding are the main concerns for tonight as additional rain and storms will move back across flooded areas.

2:00 PM Update: A new severe thunderstorm watch has been issued until 9:00 pm for most of the area.  The exception is our southern counties; however, that could change at some point.

The atmosphere is becoming increasingly unstable with high humidity and surface temperatures in the 80s.  We expect storms to quickly develop this afternoon and evening.  All modes of severe weather are possible; however, damaging winds and flooding rainfall are the two top threats.


12:00 PM Update: The timing for strong to severe thunderstorms will be this afternoon into the evening and hasn't changed.  A large line of thunderstorms will develop in western WI and track east-southeast.  The leading edge of the storms could produce widespread severe weather, especially damaging winds 

A line of storms this morning will produce more heavy rain and possibly minor flooding. 2”-4” of rainfall will be added to totals from yesterday. The line will clear out and we will see some sunshine late this morning and this afternoon. This will lead to another line of showers and storms. Some of these storms could be severe with all modes of severe weather possible with large hail, damaging winds, and torrential downpours with more flooding.

Speaking of flooding, the NWS has issued a Flash Flood Watch for all of southeastern Wisconsin except Walworth, Racine, and Kenosha until Wednesday morning. The timing of the storms will be as early as late this afternoon into early tomorrow morning. The cold front, which will produce the widespread storm activity, will usher in much cooler, drier air for the middle of the week. Temperatures will struggle to make it out of the 60s by tomorrow. The dew points will plunge into the 50s and it will feel much more comfortable.
