Long range computer models continue to show a more active weather pattern setting up once again across the upper Midwest and western Great Lakes toward the latter portion of next week through next weekend.
There was a cold front over northern Minnesota this afternoon. Showers and thunderstorms, scattered in coverage have been occurring today near this front in northern Minnesota with some lightning and heavy downpours occurring under these storms. Very weak winds aloft and no wind shear has led to pulse type storms, meaning storms will develop, rain themselves out, spit out a gust front, and a new storm develops…and that process has repeated itself for several hours today.
Most of the rest of the Northland stayed dry today under partly to mostly cloudy skies. Highs today were generally in the 70s to lower 80s.
Partly to mostly cloudy skies should continue through Monday. Expect a few showers to linger in parts of the Northland tonight and Sunday, mainly dry Sunday night and most of Monday with showers possibly returning Monday evening and during the overnight hours.
Cold front continues to drop south through the area this evening with strengthening high pressure dropping south out of Hudson Bay Canada for Sunday — Expect gusty and chilly NE winds off the Hudson Bay high to move out over Lake Superior and into the North and South Shore of the lake through Sunday night. Should have no problem getting 15 to 25 mph northeast winds with gusts possibly exceeding 30 mph! Temperatures near Lake Superior are expected to be in the mid 40s to mid 50s from tonight through Sunday night.
Farther inland will see lows in the 50s tonight and Sunday night with highs Sunday in the 60s and 70s.
A slow moving area of low pressure is still expected to affect the upper Midwest for Monday and Tuesday, this system should bring some rain showers to northeast Minnesota and northwest Wisconsin from Monday afternoon through Tuesday. Isolated thunderstorms are also possible. Lake wind continues Monday and Tuesday the way it looks now.
Looks like will get a wind shift along with warmer temperatures again for the middle of next week (Wednesday and Thursday) Highs possibly back up around 80 degrees next Thursday.
