Most of our Minnesota towns and parts of Douglas County are under a slight risk of severe storms, with a marginal risk for nearly the rest of the Northland. Large hail, gusty winds and heavy rain will be the main threats.
We’re watching a low pressure system approach from the west. That will slide into the Northland during the morning, bringing a chance of showers and storms to the area. Some strong to severe storms are possible. The storms will move out, but some showers and storms may redevelop in the afternoon as the low passes. Winds trend S to SW 5-15 mph, but turning NW as the system passes by. Highs range from the low to mid 70s north to near 80 south and east.
TIMING OF STORMS TO ARRIVE:
- Borderland: 5 AM and 8 AM
- Iron Range, Brainerd Lakes, Arrowhead: 6 AM and 9 AM
- Twin Ports, I-35 Corridor: 9 AM to 11 AM
- Northwest Wisconsin: After 10 AM
Once the system moves out, we’ll see skies gradually clearing from northwest to southeast. Winds trend NW to NNW around 2-8 mph. Lows fall back into the 40s to low 50s, but if winds calm enough and skies clear, some upper 30s are possible on the Iron Range.
Skies remain mostly sunny to partly cloudy as high pressure settles in to the northwest, however, a weak wave in the jet could spark a 20% chance of pop-up showers in the afternoon. Winds will be breezy out of the NW around 5-15 mph. It’ll be cooler, with highs in the mid 60s to mid 70s. Skies remain mostly clear to partly cloudy Wednesday night with a light N wind. Lows fall back into the 40s to low 50s, but some 30s are possible in spots.
THURSDAY AND FRIDAY:
High pressure will continue to dominate our weather, keeping the skies sunny to partly cloudy and on the cool side. A weak wave could bring a 20% shower chance to our east Thursday, but I’m not totally sold on that yet. Winds will remain northerly Thursday, but turn more E and SE into Friday. Highs will be in the mid 60s to low to mid 70s. Lows fall back into the 40s Thursday night, but back into the 50s Friday night.
Most of Saturday looks dry, but Sunday is looking rather wet unfortunately as a slow-moving low pressure moves in. The models have really slowed down on the timing of this system, so that’s something I’ll be watching over the next several days. Highs will climb back into the mid to upper 70s as winds become more S to SW.
