Night-time Update: Scattered storms work out of the area until closer to sunrise

Updated: Friday, June 21st 10:10pm:

Storms are over for most of the area until closer to daybreak. Here's the latest image on our radar: 

The lingering activity will continue on its northward drift.

Updated: Friday, June 21st 6:10pm:

We have not had any warnings since just before 5pm this evening, which is a great sign. Storms continue, but are slowly wobbling north of the I-94 corridor. I'm hopeful that should leave Milwaukee dry for outdoor events this evening. At least until well after midnight. In the meantime we have other weather things going on down at the Summerfest grounds. Check it out: 

 This camera view is pointed at Summerfest and you cannot see a thing as fog has rolled in big time on the lake breeze. As you can see it's also providing a cooler set up in the metro. So here's the good news. Look at our in house model at 8pm: The activity you see here is just north of I-94 and will continue to work north and then dissipate by around 10pm. Severe weather moving forward is decreasing significantly for tonight. But head's up for additional rounds of rain and storms by 3am Saturday morning. That will last until around noon. Then we may have a solid break with the last round and best potential for severe weather as the cold front approaches northwest cities, like Fond du Lac, around 5pm. That could hit the metro around 7pm and should be out by 9pm. After that we salvage the weekend with a lovely day Sunday.

Storms are pulsing up to severe limits at this time. Here's the latest on the alerts: 

 This warner cell working into southwest Dodge and northwest Jefferson county is only working east at about 20 mph. Here's some locations in line of this storm. The concern is gusty wind to 60 mph and hail up to quarter size. We continue to monitor additional storms that as of now are under severe limits. However, some contain lightning and downpours are likely in most storms that build. Storm chances will continue through the evening across southeast Wisconsin. Stay with CBS58 for continuous updates. Additionally, on and off rain and storms will still be with us through late Saturday evening. Any locations that see repeated storms overhead may see rainfall amounts exceeding two inches. Milwaukee county is not officially included in the watch but can still expect chances for storms this evening and periodically tomorrow. 

Updated: Friday, June 21st 1:45pm:

Scattered thunderstorms are beginning to pop near the front in SW WI. These storms are already producing very heavy rainfall and will continue to strengthen as they move to the east throughout the afternoon. 

Of note, there is a lake breeze which is keeping temps and dew points a bit lower lakeside. That being said, there remains a level 1, Marginal Risk, in place for all of SE WI this evening for damaging winds.

-------------------------------------------------------

Updated: Friday, June 21st 11:30am:

All eyes are on the stationary front to our south that has been slowly, but surely, lifting northward this morning. As of 11am, this front has moved into far SW WI and is sitting along the IL border. This front has been moving northward a bit slower than expected, so it may only reach the I-94 corridor at best. 

Where this warm front ends up will be the focus for training thunderstorms between 3-10pm. Storms may be strong to severe at times with damaging wind being the main concern along with the flash flooding potential. 

The Flood Watch may be expanded southward early this afternoon if the slow northward moving trends continue regarding this front.

A few showers have popped up Friday morning but no thunderstorms yet. That thunderstorm risk doesn't start increasing until after 3 p.m. Friday afternoon. 

Here's a look at the radar image that will update with time:

With the threat for heavy rain both Friday and Saturday. A flood watch has been issued for a number of counties in Wisconsin including Fond du Lac, Dodge, Washington, Jefferson and Waukesha Counties locally. Heavy storms and storms going over the same region multiple times could inflate rain totals above 2" in these locations.

The rest of the severe risk and storm chances outlined below are on track.

Our rain chance will ramp up as we head into the beginning of the weekend. After a mostly dry start to the day Friday we see showers and storms return Friday afternoon and evening. Best chances Friday are after 3 PM. 

Some of the storms that form Friday afternoon and evening could be on the stronger side. All of southeast Wisconsin is under a Level 1 Marginal Risk for severe weather with the western fringes of Fond du Lac, Dodge and Jefferson Counties and areas west of there under a Level 2 Slight Risk.

The better storm chance arrives on Saturday with scattered storms likely throughout the day from the morning through midday and into the afternoon and evening. The best chance for strong to severe storms might be along the cold front with a line of storms Saturday evening.

Once again, strong to severe storms are possible with a better chance for seeing severe storms Saturday than Friday. Inland and western counties are under a Level 2 Slight Risk with a Level 1 Marginal Risk near the lakefront. 

For both Friday and Saturday the main threats will be wind and flooding. A lot of rain is possible which could lead to flash flooding, ponding on roadways and minor street flooding. Some hail or an isolated tornado both days is also possible.

Rain totals from Friday into Saturday range from 0.50-1.50" for most of southeast Wisconsin but some locations could definitely get 2-3" of rain with storms. Because of the expected heavy rain, Fond du Lac, Dodge, Washington, Jefferson and Waukesha Counties have been added to a Flood Watch from Friday afternoon through Saturday night.
