*Friday looks like another hot day across the Northland with highs in the upper 80s to lower 90s, but it does look like we may get a slightly stronger lake wind to develop during the afternoon and evening, and if this is the case, temperatures near Lake Superior could drop from the 80s to the 60s later Friday afternoon. Dew points on Friday are forecast to range from the upper 50s to middle 60s so it will remain a bit humid. An isolated shower or thunderstorm is possible on Friday, but the majority of the Northland should stay dry!

*4th of July weather continues to look hot with highs in the middle 80s to lower 90s in northeast Minnesota and northwest Wisconsin. A few isolated showers and thunderstorms are possible on Saturday, but the majority of the Northland should stay dry!

Drought conditions are also worsening in far northwest Wisconsin with nearly 2% of the state now in Moderate Drought (orange area on map) up from 0% last week while 7% of the state is classified as Abnormally Dry (yellow area on map) which is up from 1% last week.

The map below shows how much additional rain is needed to bring precipitation totals to within a half inch below normal.

The darker orange area which covers all of northeast and northern Minnesota needs 3 to 6 inches of additional rain to get us closer to where we should be at for this time of the year.

I’m still seeing signs in the long range for a wetter weather pattern setting up across the Northland, especially from next week to the end of this forecast run which is July 17th.

A few showers and thunderstorms developed this afternoon across southern portions of northwest Wisconsin. These storms moved very slowly so they did produce some brief torrential downpours.

Here’s how this afternoon’s isolated thunderstorms in northern Wisconsin and upper Michigan looked on Goes-16 sandwich satellite imagery. SW upper level winds push the higher clouds NE while storm motions were nearly stationary, or toward the south today, pretty cool!
