.SHORT TERM...
Issued 227 PM CDT Mon Sep 8 2025
Tonight through Wednesday night:
Modest southerly winds and warm advection will continue tnt
into Tuesday, while vorticity maximums over the nrn Great
Plains slowly approach srn WI late Tue. The north to south band
of broken mid level cloud cover over south central WI is
associated with 850 mb warm advection and frontogenesis, and
should gradually shift ewd and weaken. Light southerly winds
tnt should be enough to inhibit fog formation along with milder
temps, followed by high temps rising into the middle 70s for
Tue.
A slow moving shortwave trough comprised of a couple vorticity
maximums will pass Tue nt-Wed. Fcst soundings indicate a fairly
moist troposphere from 600 mb upward with very skinny and
marginal elevated CAPE. The overall forcing is weak but enough
for 20-30 percent chances for showers and storms. A dissipating
and dry cold front will then pass Wed nt.

A large high pressure area will then move from Ontario into srn

Light enely winds and above normal temps are forecast for srn
WI during this time. The upper ridge will then hold in place

Canada to Lake Huron for Sun. At the surface a warm front will

much uncertainty on the track of the upper low which will have
