Another day without a lot of sunshine — A few pockets here and there with some sun today but overall skies were mostly cloudy once again today. Highs were milder than the past few days with temperatures this afternoon in the 70s although cooler temperatures in the 60s were found over the Brainerd Lakes area thanks to some rain this afternoon.
A few showers and thunderstorms will continue to drift slowly east or southeast across northeast Minnesota and possibly into far northern Wisconsin later in the evening before this precipitation ends later tonight. Brief heavy downpours and some lightning will continue to be the main threats out of the storms this evening. Note: The overall potential of severe weather is very low due to a lack of wind shear, but a few storms could pulse up in intensity for a short period of time with a threat of hail or gusty winds, similar to what occurred around the Brainerd area just before 4 PM today.
Later tonight areas of low clouds and fog will likely develop especially over western-southern portions of the Northland, otherwise partly cloudy skies will rule with lows in the 40s and 50s.
Partly to mostly sunny skies Saturday after the low clouds and fog burn off. Highs in the upper 70s to middle 80s.
A cold front moves slowly SE into the upper Midwest Sunday. Instability build ahead of this front with low level moisture also increasing with dew points Sunday afternoon ranging from 65 to 70 degrees in east central Minnesota and northwest Wisconsin, much drier air over northern Minnesota. Highs Sunday in the middle 70s to lower 80s. Note: A few showers and thunderstorms could develop in parts of the Northland late Saturday night through Sunday afternoon thanks to a cold front which will move across the area.
