There remains a slight risk for severe thunderstorms over south central and southeast Wisconsin late this afternoon and early evening. The slight risk includes most of south central and southeast Wisconsin, including the Milwaukee metropolitan area, as well as Madison, Sheboygan, Janesville, Racine, Kenosha, Port Washington and West Bend.
A cold front over western Wisconsin early this afternoon will move through southern Wisconsin late this afternoon and early this evening, setting off scattered showers and thunderstorms. The atmospheric wind shear is increasing and the atmosphere is becoming more unstable due to the thin spots and breaks in the cloud cover. However the low level winds are turning to the southwest and west, which is decreasing the low level convergence and resulting updraft strength to fuel the thunderstorms. Never the less, isolated thunderstorms may yet turn strong to severe between 4 pm and 7 pm this evening.
The cold front will exit southeast Wisconsin early this evening ending the thunderstorm threat.
Stay tuned for the latest forecasts and statements concerning the severe weather potential.
