Rain should be ending around 10 PM. Evening flooding remains a concern.
7:30 PM Update:
The cold front has passed through the area as strong northwest winds have arrived. The shield of rain will move across the entire area by 10 pm giving the area a chance to dry out overnight.
Many areas across Dodge and Fond du Lac counties picked up 2" to 4" of rain creating some flooding issues.
5:30 PM Update:
The instability that brought very heavy rainfall and hail earlier this afternoon has dissipated. The cold front is bringing a change in the wind and eventually an end to the rainfall.
Expect a few lingering storms over the next hour; however, most of the rain this evening will be light to moderate through Midnight. Rain will move out and dry weather will be with us overnight into Thursday morning.
2:15 PM Update
Storms that pulsed up an hour ago have weakened below severe limits. There were plenty of hail reports across Waukesha and Washington counties. Thankfully the storms have lost some energy.
We do expect isolated showers and a few storms possible through 4 pm; otherwise, light to moderate rain arrives for the evening.
Heat, humidity and instability are triggering storms to quickly fire this afternoon.
Storms that pop are heading northeast around 30mph. We currently have one Severe Thunderstorm warning in progress impacting Waukesha and Washington counties. This runs until 2pm. We've had a report of large hail of 1" in diameter in Merton, penny size hail in Oconomowoc as well as the potential for gusty winds to 60mph. Additionally, heavy rain and frequent lightning are likely in storms that brew today. You can see that green circular line that I've pointed out. That is outflow winds from these storms. So there's a good chance gusty winds are pushing down through Waukesha county. That boundary could help fuel additional storms closer to Milwaukee. We're monitoring the situation closely this afternoon. Be prepared to take it indoors with any storms that quickly build. We've got you covered here, online and on tv. It's a great time to also download the CBS58 Ready Weather App to have another way to get warnings on the fly.
