It is cooler in far northern Minnesota with temperatures in the 70s this afternoon, and even cooler closer to Lake Superior with temperatures in the 60s and 70s thanks to the lake breeze!
Temperatures were one story, the extremely muggy airmass is the other! Dew points this afternoon were steamy with values in the mid 60s to mid 70s which combined with the hot temperatures has led to heat index readings climbing into the 100 to around 110 degree range in eastern Minnesota and northwest Wisconsin, incredible!
Tonight: A frontal boundary should remain over western to northern Minnesota. Showers and thunderstorms are expected to gradually develop during the night as convergence near the front helps break the cap. Once storms develop they will have lots of energy and moisture and wind shear to tap into, and this could lead to a few strong to severe thunderstorms in parts of the Northland later tonight with damaging winds and hail being the main threats. Lows tonight ranging from the 50s near Lake Superior with 60s and 70s elsewhere.
Saturday and Sunday: Cold front moves slowly east and should be near the Minnesota/Wisconsin state line by Saturday evening, then into western Wisconsin by Sunday morning, the front will then get a better push to the south/east Sunday afternoon.
The potential for severe weather is lower for Saturday, but enough instability will still be present for thunderstorm development with isolated stronger storms possible during the afternoon/evening hours.
Highs Saturday in the 70s and 80s, a few locations in northwest Wisconsin and eastern Minnesota might get up to around 90 degrees, but it doesn’t look as hot Saturday as it was on Friday.
It will remain muggy through Saturday with dew points in the 60s and 70s across the Northland!
Lower dew points move in on Sunday with highs in the 70s to lower 80s.
Near Lake Superior: Temperature forecast will be a challenge through Saturday due to the lake breeze. East wind will continue tonight, but could shift directions at times on Saturday. When the wind is out of the east, it will be cool, but if or when the wind direction shifts, temperatures will warm up considerably! A better shot for a warmer west wind occurs on Sunday the way it looks now.
