Less humid conditions are slowly spreading south out of northern Minnesota this afternoon as a cold front exits the Northland to the south/east. 5 PM dew point temperatures ranged from the 40s and 50s across northern Minnesota while it was still soupy farther south with late day dew points in the mid 60s to low 70s in east central Minnesota and over all of northwest Wisconsin.
Showers and some thunderstorms affected parts of the Northland this morning into mid afternoon with the bulk of that activity staying near and south of Highway 2 in northeast Minnesota and affecting most of northwest Wisconsin. Heavy downpours and lightning were the main hazards out of that activity.
As of late afternoon most of the Northland was dry under sunny skies over northern Minnesota while it was still mostly cloudy in most of northwest Wisconsin.
Tonight will be pleasant under clear skies except in northwest Wisconsin where a few showers and clouds will persist this evening before some clearing takes place from west to east during the night. Expect some fog to develop later in the night due to the recent rain. Lows tonight will range from the low 50s to low 60s but some of the typical cold spots could slip into the 40s.
Mild temperatures on the way for Wednesday but it won't be very humid. Highs are forecast to be in the 70s and 80s with dew points ranging from 50 to the lower 60s.
High pressure passing through the region tonight will slide off to the south/east Wednesday as tonight's cold front turns into a warm front while it lifts from northern Iowa into south central Minnesota. Intense heat will continue over the western High Plains region while a reservoir of very humid and unstable air sets up near the warm frontal boundary on Wednesday -- A round or two of strong to severe thunderstorms are expected Wednesday or Wednesday night affecting portions of western, central and southern Minnesota. With the very strong winds aloft in place the potential is there for a higher end wind event to occur somewhere from southern North Dakota through south central Minnesota. It looks like our area will be far enough north for severe weather, but there could be some showers or thunderstorms at times especially from Wednesday afternoon into Wednesday night. A stronger storm can't be ruled out mainly over far southern portions of the Northland.
Thursday looks mainly dry with highs in the 70s to around 80 degrees.
