Strong Tornadoes, Very Large Hail, And Destructive Winds Possible Through Monday Evening
This is not the way to end an extended holiday weekend. A Moderate Risk of severe weather - threat level 4 of 5 on the scale - is in place across a good portion of southern and central Minnesota as we head throughout the rest of Monday into Monday Night. We are watching the potential for strong, long-tracked torndoes, destructive wind gusts to 80 mph, and large hail up to 2.5" in diameter with storms. Storms will also be moving fast at 50-70 mph.
There is a PDS (Particularly Dangerous Situation) Tornado Watch in place through 10 PM Monday evening just west of the immediate metro area, but including places like St. Cloud, Fairmont, Willmar, Alexandria, Brainerd, Fergus Falls, Detroit Lakes, and Grand Rapids. PDS watches are higher end watches indicative of the higher-end severe weather that could occur. According to NWS Twin Cities, this is the first PDS Torando Watch to cover any part of the state since June 12, 2013. Probabilities for at least 2 tornadoes, at least 10 hail reports, and at least 10 wind reports are all on the high end (80-90%), as well as the potential for at least one strong tornado, at least one wind event of 75+ mph, and at least one hail report of at least 2" in diameter.
Above is an explainer of what that "Particularly Dangerous Situation" means in a PDS watch.
A second Tornado Watch is in place across southwestern Minnesota, including Marshall, Jackson, and Worthington, until 6 PM.
Forecast loop from 4 PM Monday to 1 AM Tuesday.
Here is just how one model shows the potential for severe weather as we slide through the late afternoon into the evening hours. If we can get individual storms to form late this afternoon in the 4-6 PM timeframe across the Tornado Watch sector, these would be the storms we have to watch for strong, long-track tornadoes (as well as very large hail). Behind that, a line of storms will form capable of all severe weather (but especially strong winds) that'll move into the metro around the 8-10 PM timeframe.

Flood Concerns Continue Up North
The storms on Monday into Monday Night are also bringing a lot of rain along with them, especially up in northern Minnesota - areas of the state that don't need more rain at the moment. Totals from Monday into Tuesday are expected to be in at least the 1-2" range.
