A nice Labor Day across the Northland under mostly sunny skies, but clouds are starting to increase from S-N late this Monday afternoon. Highs today were in the low to mid 70s, except for slightly cooler temperatures closer to Lake Superior due to an east wind today.
Becoming mostly cloudy with scattered rain showers developing in east central Minnesota and northwest Wisconsin as deep moisture advects north into the area. Lows tonight will range from around 50 to the middle 60s, coolest temps in far northeast Minnesota.
Rain! Mostly cloudy skies are forecast with highs in the 60s and 70s. A warm front lifts N-NE through the Northland which will be followed by a cold front with deep moisture already in place, the fronts will help lift/scoop up this moisture which will cause occasional rain and showers in northeast Minnesota and northwest Wisconsin. It will also be on the muggy side on Tuesday with dew points in the mid 60s to around 70 degrees. Note: A few thunderstorms are also possible Tuesday with some CAPE over the area, but no severe weather is expected, but these storms will produce torrential rainfall where they do occur.
High pressure will return to the Northland Wednesday through Saturday the way it looks now with the tropical moisture getting pushed farther south. We’re looking at mainly dry weather in our area late this week with daytime highs in the 60s to lower 70s, overnight lows in the 40s with some 30s likely in the traditional cold spots.
