.DISCUSSION...

Issued at 200 PM CDT Fri Oct 24 2025



Forecast Through Saturday...

Cloud cover returned to the region during the morning hours as 

high clouds arrived from the west. These clouds are expected to 

progress out of the region through the afternoon and evening, 

bringing back some sunshine and clear skies for the late afternoon

and evening period. Next round of clouds will arrive during the

overnight period as an upper shortwave approaches the region. This

feature will be accompanied by some scattered (15-25%) shower

coverage by Saturday morning, but lack of significant moisture

will largely hamper both amounts and coverage across out area.

Latest guidance does take this feature a bit more easterly,

expanding coverage of showers into the early afternoon for

portions of eastern Wisconsin. Regardless, overall impacts are

expected to be low.



Rest of the forecast...

Dry conditions are expected from Saturday night through Monday as

high pressure builds in overhead. Longer range guidance then

suggests the development of a closed upper low over the upper

Midwest, that will then dive southeastwards into the southern 

Great Lakes. This could bring our next round of showers to the 

region as we remain on the fringes of this potential system, but 

timing/coverage resolution remains low with this features. Thus, 

carried some broader, but lower confidence (20-30%) pops for the 

Tuesday/Wednesday timeframe.



Temperatures...

A brief warmup is possible over the weekend with highs getting

into the 50s everywhere including a few high 50s for Sunday.

Following this, temperatures cool back down for the next couple of

days, with highs staying largely in the 50s each day. Overnight

temperatures next week will also largely stay in the lower to

middle 30s, except for a few of the coldest spots in the north

which may briefly hit the upper 20s at times.

.AVIATION...for 06Z TAF Issuance

Issued at 1052 PM CDT Fri Oct 24 2025



Mid clouds will thicken overnight as a short-wave trough 

approaches from central MN. This system will bring a brief period

of light rain to the southwest half of the forecast area late 

tonight through about midday Saturday, but flight conditions are 

expected to remain VFR. Even after the rain ends, ceilings between

5000-7000 ft AGL are expected to linger through much of the day, 

with partial clearing spreading from NW to SE during the late 

afternoon and evening.



Light and variable winds persist through early Saturday morning,

followed by SE-S winds of 5 to 10 knots for the rest of the day.
