Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast – Confidence: High.
Tonight (May 27)
A frontal boundary will be draped over the area Tonight. Partly to mostly cloudy skies are forecast with any lingering showers or thunderstorms ending this evening. Low temperatures will be in the 40s and 50s with winds becoming east at 5 to 15 mph.
Thursday and Thursday Night (May 28)
Low pressure along with a cold front approach from the west during this period while a warm front lifts slowly NE through Northern Minnesota and Northern Wisconsin. A few showers or thunderstorms can’t be ruled out on Thursday but a better chance for showers and possibly a few thunderstorms arrive Thursday Night. Partly to mostly cloudy skies are expected this period with highs on Thursday in the 70s and 80s but it will only be in the 50s closer to Lake Superior. Lows Thursday Night will be in the 50s and 60s with 40s closer to Lake Superior. Winds during this period will be out of the south, east, or southwest at 10 to 20 mph.
Note: The chance for severe thunderstorms for Thursday and Thursday Night is very low in Northeast Minnesota and Northwest Wisconsin. Instability looks pretty marginal. Winds aloft will be fairly weak. Not much wind shear either. Moisture will be increasing though, so there is a chance for locally heavy rainfall especially by Thursday Night.
Extended Forecast – Confidence: High.
Friday through Sunday (May 29-31)
A cold front will be pushing south/east through Eastern Minnesota and Northern Wisconsin on Friday. Rain chances will linger in most of the Northland on Friday but these chances will be decreasing from NW-SE during the Afternoon hours. Strong high pressure moves in Friday Night and lingers near the area through Sunday so it will be dry during that aforementioned time frame. It will be cool though, and there is a chance for frost inland from Lake Superior Saturday Night-early Sunday Morning.
High temperatures from Friday through Sunday will be in the 50s and 60s with lows Friday Night generally in the 40s with lows Saturday Night in the 30s and 40s.
Long Range Forecast – Confidence: Medium to High.
(June 1-5)
This entire period holds a chance for showers or thunderstorms as low pressure, warm front, cold front, and upper level trough move east out of the Western U.S. and Northern Plains. All day rains are not expected with this type of setup, but scattered rain/thunderstorms could erupt from time to time next week. Near to possibly above average temperatures are expected from the 1st-5th.
