Discussion

For the rest of the day, the widespread rainfall from early this morning has largely moved through the area. However, scattered showers are still expected to linger into this afternoon for far northeast Minnesota and northwest Wisconsin, which will squeeze out a few more hundredths of an inch of precipitation. As the rain showers depart, patchy fog is expected to linger in their wake. This will be particularly noticeable around the Brainerd Lakes area into the evening. Cloud cover will remain in place tonight with lows dropping into the upper 30s and lower 40s across the Northland.

Our active weather pattern continues right into Wednesday as another low pressure system and mid-level wave approach from the Dakotas. This will spread another round of widespread showers across the region. Instability that will accompany these showers tomorrow will lead to embedded thunderstorms during the Wednesday afternoon and evening hours. Though the overall chances for severe weather remain low, some communities could see small, pea-sized hail for a brief period sometime in the late afternoon. South to southwest winds will also be quite breezy ahead of this system, bringing warm air into the region from the south and temperatures will be into the upper 50s and mid 60s for most locations.

The rain comes to an end late Wednesday night as a cold front sweeps through, leading to a quiet end to the work week. High pressure will build in for Thursday and Friday, bringing a return to plentiful sunshine across the region. With northwest winds expected behind the departing system, temperatures will be a bit cooler on Thursday, with highs topping out in the upper 40s to mid 50s. Pleasant conditions will hold through Friday, with high temperatures moderating back into the mid 50s to lower 60s under mostly clear to partly cloudy skies.

Heading into the weekend, the pattern becomes active once again. Global models point to a deepening upper-level trough moving into the central United States, bringing broad chances for precipitation to the Northland from Saturday through Monday. While the exact timing and placement of these weekend showers remain a bit uncertain, multiple rounds of rain are possible. Despite the clouds and rain, temperatures will remain warmer than normal through the weekend. Highs will consistently reach the mid 50s to lower 60s, while overnight lows will comfortably stay above freezing, generally resting in the upper 30s and 40s.

Aviation

MVFR and IFR conditions will prevail tonight. Expect conditions to vary quite a bit with periods of fog. Ceilings may trend slightly up Wednesday morning, but still remaining predominantly IFR/MVFR. A short wave and cold front will pass through during the afternoon and evening. Rain and a line of thunderstorms are looking more likely, and this would affect all terminals except possibly INL. Some of the storms could be strong to severe, with large hail and damaging winds not out of the question. Storms will pass through from west to east during the evening.

Marine

Issued at 155 PM CDT Tue Oct 27 2026

Hazardous conditions for small vessels will continue into tonight across western Lake Superior. East winds gusting up to 30 knots and waves building up to 5 feet will persist before winds gradually weaken and shift to the south and southwest tonight. Small Craft Advisories remain active for most nearshore zones, dropping off in portions late this afternoon through early Wednesday morning as conditions slowly improve. Winds increase over western Lake Superior again on Thursday, and more Small Craft Advisories may be needed.

Fire weather

Issued at 155 PM CDT Tue Oct 27 2026

Fire weather concerns remain minimal through the period due to recent rainfall and cool conditions. Breezy east to southeast winds gusting 15 to 25 mph this afternoon will shift to the southwest tonight. Another round of wetting rain and isolated thunderstorms is expected on Wednesday. Drier weather returns for Thursday and Friday with moderate afternoon humidity (>40%) and northwest winds. Thursday's northwest winds will be stronger than Friday, with gusts up to 20 mph.
