Monday and Monday Evening …
No Weather Hazards expected …
A clipper system moving across the Dakotas this morning will quickly shift eastward across the Upper Midwest later today, and into the Upper Great Lakes region tonight. This system will push a trailing cold front eastward across our area around, or shortly after midnight tonight.
DISCUSSION…
While conditions will turn colder as blustery northwesterly winds develop in the wake of the front overnight, conditions should remain relatively mild (lower 40s) in advance of the front this evening. Gusty northwest winds (up to 35 mph) overnight will then drive temperatures back down into the 20s into early Tuesday morning. Most, if not all, of precipitation associated with the clipper system will remain north of the area, so we continue a mainly dry forecast for the area through Tuesday.
Daily low temperatures and daily high temperatures are on the way up. We’re gaining about 2 minutes of daylight every day in the progression toward vernal equinox, March 20, 2023. We gained 3 minutes of daylight on Monday, February 20, 2023.

552 AM CST Mon Feb 20 2023
.SHORT TERM… Issued at 344 AM CST Mon Feb 20 2023
Through Tuesday…
Winds have turned northerly across the area in the wake of a weak cold frontal passage. While a slightly cooler airmass is working southward into the area and resulting in subfreezing temperatures across parts of the area early this morning, temperatures look to rebound nicely today. We should see the winds go light and variable for a period this morning before they settle back to a southerly direction this afternoon. This should help temperatures rebound back into the 40s this afternoon under partly sunny skies.
A clipper system moving across the Dakotas this morning will quickly shift eastward across the Upper Midwest later today, and into the Upper Great Lakes region tonight. This system will push a trailing cold front eastward across our area around, or shortly after midnight tonight. While conditions will turn colder as blustery northwesterly winds develop in the wake of the front overnight, conditions should remain relatively mild (lower 40s) in advance of the front this evening. Gusty northwest winds (up to 35 mph) overnight will then drive temperatures back down into the 20s into early Tuesday morning. Most, if not all, of precipitation associated with the clipper system will remain north of the area, so we continue a mainly dry forecast for the area through Tuesday.
Winds will abate across the area during the day Tuesday as a weak surface high quickly shifts across the area in advance of the next storm system expected to impact the region Wednesday into Thursday. Expect high temperatures Tuesday to be cooler, with readings likely to range from the lower 30s far north, to around 40 far south.
