SPC has issued a tornado watch until 8pm for much of southern Minnesota. The watch area technically does not include the Twin Cities metro, but it’s close enough to be watched for potential severe storms in the metro.

The watch area does include Redwood Falls, Mankato, and runs right up to the southwest metro border counties.

A warm front has pushed into southern Minnesota, and temperatures are near 80 degrees this afternoon near the Iowa border. Temps in the 70s lie just south of the Twin Cities metro where skies have cleared for sunshine today. This has destabilized the atmosphere enough to trigger another wave of thunderstorms, which may roll through the Twin Cities and southern Minnesota late this afternoon.

Keep an eye out for potential severe storms and possible tornadoes especially south of the metro along the I-90 corridor today.
