After a stretch of real nice weather around here, today’s weather took a step back to winter thanks to a potent area of low pressure which moved S/SE through the upper Midwest and western Great Lakes, cold temperatures with accumulating snow affected portions of northeast Minnesota today with rain or a mix of rain and snow affecting other areas of northeast Minnesota and far northern Wisconsin. Farther west, not much precipitation today with just a few showers this afternoon. Highs today were only in the 30s near Lake Superior with 40s farther west/south. Gusty northeast winds also occurred today near Lake Superior which made it feel even cooler!
Lingering snow and rain showers this evening near Lake Superior otherwise partly to mostly cloudy skies on the way for tonight with patchy fog possible in areas that had accumulating snow today. Lows tonight will be in the 20s with teens and maybe even a few single digits in spots up north.
Should have quite a bit more sun Saturday compared to what we had today but temperatures won’t be all that warm with highs in the 40s and 50s, coolest temps found near Lake Superior, warmest temps for western areas (International Falls, Brainerd, Aitkin)
High pressure will be in control of our weather through Sunday. The high will shift to the south/east by Sunday which will cause a southerly flow to develop across the upper Midwest which ushers in a warmer and eventually a more humid airmass — Fire weather could become an issue for parts of the Northland on Sunday since humidity values will still be on the low side.
Highs on Sunday are forecast to be in the 60s to lower 70s with cooler temperatures especially along the North Shore of Lake Superior.
A few showers or thunderstorms are possible in parts of the Northland late Sunday night/Monday morning as a warm/moist advection pattern spreads into our area. 30-40+ knot SW low level jet will be in place Sunday night with elevated instability building into northeast Minnesota and northwest Wisconsin during the night, this could set off a few boomers later in the night!
Monday and Tuesday will see an area of low pressure with its warm front and cold front affecting the upper Midwest — Warm and a little humid ahead of this system with cooler/drier air behind it. Scattered showers or thunderstorms are possible at times for Monday and Tuesday as this system moves through. High temperatures are forecast to be in the 60s and 70s early next week with a wide spread in high temps showing up per model guidance for Tuesday as a faster moving cold front would lead to much cooler temps with more clouds while a slower moving cold front would allow us to remain on the warm side for one more day. Stay tuned!
