Severe Storms Possible Monday

Heat Advisory Sunday

Hot & Humid Sunday-Monday

Warm and humid conditions will bring a severe weather potential to southern Wisconsin Sunday through Monday. There are three opportunities for storms Sunday: the early morning, late afternoon and evening, and overnight. Stay weather aware and have multiple ways to receive warnings.

Additional rounds of storms are possible Monday. The ingredients for the stronger storms are mainly east of I-90. The development is dependent upon where storms track on Sunday. Keep up with the forecast!

A Heat Advisory is in effect from Noon to 9 PM on Sunday due to hot and humid conditions. Heat is one of the most deadly weather hazards. If you must be outside for a long time, stay hydrated, wear loose-fitting and light color clothing, and find shaded areas.

Rising temperatures and humidity will lead to elevated heat indices Sunday and Monday. Hottest conditions are expected between 12-7 PM daily with high temperatures in the lower 90s and heat indices (feels-like temperatures) between 100 and 105F. There is a potential for clouds from storms to interrupt the heat on Monday.
