.DISCUSSION...
Issued at 138 PM CDT Thu Jul 31 2025
Skies are mostly clear to partly cloudy this afternoon, at least as
far as clouds go, but there are plenty of hazy skies and smoke in
the air. The flow is northwesterly aloft, which is keeping a steady
stream of smoky air making its way into the Northland from Canadian
wildfires, and high pressure centered over northern Minnesota is
producing plenty of subsidence and light north to northeast winds.
This is all essentially creating a high pressure "pool" of smoky air
that will be very slow to go anywhere over the next couple days.
Minnesota Pollution Control Agency has maintained an Air Quality
Alert through 5 PM Saturday and the Wisconsin DNR has issued an Air
Quality Alert through noon Friday. For more details, visit

health for Minnesota.
High pressure at the surface is expected to very slowly move
east/southeast Friday into Saturday, so aside from the smoke, we can
expect some sunshine, quiet weather, and generally seasonable
temperatures through Saturday. As the surface winds become southerly
on the back side of the high pressure on Saturday, we may start to
see some gradually improving conditions as far as the smoke is
concerned.
The upper level pattern starts to become a bit more wavy going into
Sunday. In addition, PWATs increase to around 1.0" to 1.5". As a
whole, rain chances will be increasing. At this time, thunder
chances look pretty low-end with little instability (
