We are in for a very nice summer-like day. Skies will be sunny to mostly sunny, so you will definitely need the sunglasses. Winds will be breezy out of the W to SW around 10-20 mph. Highs will get into the low to mid 80s, but staying slightly cooler in Grand Marais.
Skies will remain mostly clear to clear, but folks in northern Wisconsin will see more cloud cover and models bring in a slight chance of showers and t-storms overnight. Winds become light and variable to calm. Lows remain mild, in the 50s to low 60s.
A quick-moving and weak low pressure system will slide in, bringing with it a chance of showers and t-storms. The rain chances sit at 40% in northern Wisconsin, but decreases the further north you go. We could see one round in the morning, but I expect the chance to be mostly in the afternoon and evening hours. Skies will then clear into Thursday night. Winds trend E to SE around 5-10 mph. Highs will be in the mid 70s to mid 80s inland, but only in the mid 50s to mid 60s lakeside. Lows fall back into the 50s to low 60s.
The beginning of the weekend looks dry with a mix of clouds and sunshine. A warm front will approach from the south, and while temperatures will be warm already, it will bring in more humid air as well. Highs will be in the upper 70s to upper 80s inland, but remaining cooler lakeside.
We are looking at a hot and humid weekend across the Northland, but cooler temperatures will continue lakeside. Skies will be partly cloudy to partly sunny with a spotty chance of showers and t-storms on Saturday. There is a better chance on Sunday and with the heat and humidity, some of the t-storms could be on the stronger side, so we will be watching that closely. Highs will be in the mid 80s to mid 90s inland, around 80 in Duluth, but in the mid 50s to mid 60s lakeside. Dewpoints will be in the 60s, so heat indices will be in the 90s throughout the weekend.
