Current Watch Summary:

  • There are currently no watches in effect for the ALAC Weather forecast area.


There is a SLIGHT risk of severe thunderstorms this afternoon and evening (Monday 05/28)

**The NWS Storm Prediction Center indicates that a SEVERE THUNDERSTORM WATCH is likely for southern WI this afternoon (12:00pm)**

Very warm temperatures ahead of a cold front that will begin to slide into southern Wisconsin will create very unstable weather conditions across southern Wisconsin. CAPE values of 1000-1500 J/Kg, along with modest wind shear of 35-45 knots at 0-1 Km, will result in an environment that will be conducive to severe weather, including supercells producing large hail and damaging winds. Hydrographs are fairly straight according to the 12z soundings, which will only pose a low tornado threat. 

Widespread thunderstorms are expected to develop across southwest Wisconsin early this afternoon. These storms will be ahead of the cold front and will race east-northeast. The best time-frame for storms and severe weather is between 1:00 pm CDT and 5:00 pm CDT. Please use caution if planning on being outdoors, as the weather may change very rapidly. Stay tuned to NOAA Weather Radio All Hazards and the ALAC Weather Service for the latest severe weather information. Remember, move indoors at the first sound of thunder.
