.SHORT TERM...
Issued 400 AM CDT Fri Sep 26 2025
Today through Saturday:
A Canadian cold front is currently progressing swd from ne WI
and nrn Lake MI. The associated sfc trough will weaken today as
it shifts ewd so the cold front will slow down, but come off the
lake first. It should reach the Sheboygan area around 15Z and
Milwaukee around 17-18Z. Some stratus clouds may be along it and
behind it for mainly east central WI. High Temps for the day
will range from the upper 60s over east central WI to upper 70s
to lower 80s over far srn WI and south central WI. Shortwave
ridging will quickly follow tnt with the cold front continuing
to decay and stall over nrn IL and ne IA. Higher dewpoints along
and behind the front will settle over srn WI tnt bringing the
potential for areas of fog, some dense.
Another weak sfc trough will then track from MN across the nrn
Great Lakes on Sat with the front quickly returning as a warm
front. Swly winds, warm advection, and sunshine should boost
temps into the lower to middle 80s for Sat afternoon. The
trailing weak and dry cold front will then pass Sat nt.

.LONG TERM...
Issued 400 AM CDT Fri Sep 26 2025
Saturday night through Thursday:
An upper level ridge will begin to build into the Great Lakes Region
behind the exiting trough Saturday night into Sunday. This upper
level ridge is expected to sit across the central CONUS into late
next week. The large scale subsidence will help keep conditions dry
and quiet through the week.
As the sfc, a strong high pressure system in northern Saskatchewan
will progress east southeast crossing Hudson Bay into Quebec
Tuesday. Until this surface high passes to the east of Wisconsin
into Quebec, above normal temperatures will continue. Highs
will be above normal in the upper 70s to lower 80s for Sun-Tue,
but a little cooler near the lake. Northeast to east winds will
then keep temps a little cooler, especially for lakeshore areas
for mid to late week.
Looking further into the extended a trough looks to approach from
the northern Plains for the weekend. This far out timing is a bit
uncertain with the CAN having a more progressive and fast moving
trough while the GFS and EURO being slower.

A weakening Canadian cold front will track from north to south
across Lake Michigan through the day. Westerly winds will become
northerly, and be a bit breezy over the north half of the lake
this morning.
The winds will then veer to easterly later tonight then southerly
on Saturday with the passage of a warm front. Another Canadian
cold front will then track from north to south across the lake
Saturday night with another wind shift to northerly. High
pressure around 30.1 inches will then set up over the Upper Great
Lakes Sunday and Monday, leading to light and variable winds with
a lake breeze each day.
