Strong Storms, Heavy Rain Possible on Sunday
UNDATED – It will become hot and humid across much of the area today as a warm front lifts north. Highs this afternoon will reach into the 90s across eastern and southern Minnesota and west central Wisconsin. Combine the heat with dew points near 70 and it will feel like 100 degrees during the late afternoon. Take extra precaution if you work or spend time outside today.
Strong to severe thunderstorms will develop during the afternoon across western Minnesota as a cold front moves in from the Dakotas. Large hail, damaging winds and a few tornadoes are possible. The storms will spread east early tonight across central and southern Minnesota and west central Wisconsin. Severe storms are likely early on.
In addition, a wave of low pressure will ride northeast along the cold front and this will enhance the rainfall across much of central and southern Minnesota. A flash flood watch covers the area through Monday morning. Two to three inches of rain may fall tonight and it may fall quickly, leading to flash flooding. The rain tonight will be over areas saturated from rainfall last week. Take extra precaution tonight if you live near flood prone areas.
The weather system will finally move east of the region on Memorial day.
