Lea Zmurko: Tuesday morning thunderstorms

July 30: Mostly cloudy with some isolated storms

The hot and humid conditions continue as isolated thunderstorms move across the Northland. Highs will be in the mid 80s by the afternoon.


A system of strong thunderstorms moved eastward across central Minnesota into northern Wisconsin this morning. No severe weather is expected, but the storms are bringing strong winds, heavy wind and cloud-to-ground lightning across the region.

More isolated severe thunderstorms are slated to arrive Wednesday evening into the early hours of Thursday morning. The key hazards include damaging winds, large hail, and locally heavy rain with risks for flooding.

Humid conditions will also be lasting this week as dewpoints remain in the 60s through the evening. This moisture in the air is keeping the environment muggy and uncomfortable today. The high dewpoints are also a contributing factor to the dense fog lingering across northern Wisconsin this morning.

With a south wind, the warm temperatures are set to continue throughout the work week. Temperatures reaching widespread 90s by the weekend. Conditions will also continue to dry out then and the heat is forecasted to break by early next week as a deep trough moves in.
