Enjoy sun and warm temperatures Friday along with light winds. Showers and thunderstorms will develop late Friday night into early Saturday as humid air moves back into Minnesota. Thunderstorms will be possible through the weekend.
Warm sunshine Friday dominated by high pressure
High pressure sits over Minnesota Friday keeping skies filled with sunshine and stable.
High pressure also means light winds during the day Friday. Winds aloft, about 4,000 feet up — what we call a “low level jet stream” — will develop overnight Friday night.
This low level jet stream acts like a conveyor belt of heat and moisture. You’ll notice dew points increasing to muggy levels again for the weekend.

Moisture moves north touching off thunderstorms
With the warmth and humid air moving back in, that will touch off thunderstorms late Friday night into early Saturday.
We’ll see conditions mainly dry midday Saturday with the possibility of some more isolated storms popping with daytime heating. Rainfall amounts will be heaviest likely north of the Twin Cities.
Sunday into Monday will remain unsettled as steamy air sits over Minnesota and a cool front moves through Sunday night into Monday.
Behind that cool front, temperatures will be in the 70s and low 80s midweek with a stretch of sunshine.
