MINNEAPOLIS (WCCO) — Thursday is another Next Weather Alert day as dangerous heat and another round of potentially severe storms threaten Minnesota.

Some thunderstorms are moving through western and central Minnesota in the early afternoon. The system is pulling towards St. Cloud and Brainerd, just north of the Twin Cities and is dropping golf ball-sized hail.

Swaths of central and eastern Minnesota are under a severe thunderstorm watch through 5 p.m. The watch has been issued for Anoka, Chisago, Isanti, Kanabec, Pine, Ramsey, and Washington counties, as well as several counties in northwestern Wisconsin.

These severe storms have put out an outflow boundary; a line of rain-cooled air rushing towards the Twin Cities. As it passes by, it could bring a brief sprinkle and gusty winds, but could also produce more severe weather if it meets the edge of the warm front currently over southeastern Minnesota.

Next Weather Alert: Damaging Winds, Heavy Rain, Possible Tornadoes

A more active system is expected to arrive in the evening, especially after the dinner hours. Western Minnesota is facing a moderate risk of severe weather, and a large portion of Minnesota is seeing an enhanced risk. Northern Minnesota and southeastern Minnesota are at a slight risk.

Damaging winds and heavy rain will be the main concerns with this round of storms, though hail and even tornadoes are also possible.

Western Minnesota – from the northern to southern border –  is under the greatest risk for tornadoes. The storms will head eastward in the evening hours, and the greatest risk for severe weather will be between 10 p.m. and 2 a.m. in the Twin Cities.

There is also the risk of severe flash flooding, as the ground is already primed from last night’s torrential rain. Over the past 24 hours, some areas in western Minnesota saw over 4.5 inches of rain, and will get hit again by downpours on Thursday night.

Temperatures will soar throughout the day Thursday, reaching nearly 90 in the Twin Cities. Dew points will also be high as there was a record amount of moisture in the air on Thursday morning, according to the National Weather Service.
