***Watch WISN 12 for updates on the potential for severe weather!***
Thank you for stopping by the Weather Watch 12 blog! Summer for a day! Temperatures surged into the 80s across almost all of southeast Wisconsin Sunday afternoon.
The heat is helping to destabilize the atmosphere, and an approaching cold front and some upper level support will help to trigger showers and thunderstorms late in the afternoon and into Sunday evening. We are on Weather Watch today and tonight for severe weather. If severe weather does develop watch for updates on WISN 12.

Below is the incredible warm that covered the area around 1pm Sunday. 81 in Milwaukee…I’m loving it! Milwaukee is marked with the black ‘*’.
The warm and increasingly humid airmass was already beginning to fire thunderstorms well west of our area around 2pm Sunday. A good way to detect where thunderstorms may develop, or are already developing is to look at the visible satellite. The visible satellite just after 1pm Sunday showed the clouds building in eastern Iowa and southwest Wisconsin. This is the area that could see strong to severe storms first.
The greatest threat for severe storms in southeast Wisconsin is between 5pm and 11pm. During this time severe storms COULD move into the area. And IF any of these cells are discrete supercells they could turn severe quickly, and with a lot of shear or winds helping the storms to rotate in our area, any storm could produce isolated tornadoes. I think the greatest tornado threat for the remainder of Sunday is from Madison to Oshkosh and points west. A strong tornado is even possible in this area.
The day 1 tornado outlook from the Storm Prediction Center is also along these lines. Keep in mind the percentages represent the chances of a tornado within 25 miles of a point. So while there is a chance today(certainly higher than most severe weather days), the odds are still small when viewed from the percentages.
The severe threats for late Sunday include the chance for large hail, strong winds, and isolated tornadoes in our viewing area. While I mention the threat for isolated torandoes, that is ONLY if we see supercell thunderstorms move into this part of the state. Right now that threat is highest from southwest Wisconsin into the northern part of the state – closer to low pressure and also a warm front.
If you have a severe weather report to pass along to the Weather Watch 12 team, please post it to the comments section of BOTH the blog and our Facebook page: Weather Watch 12
