.KEY MESSAGES...
- Above normal temperatures and dry conditions are expected this
  week with cooler temperatures near Lake Michigan via lake
  breezes.
&&
.SHORT TERM...
Issued 300 AM CDT Sun Sep 28 2025
Today through Monday:
Upper ridging will build east from the Mid MO River Valley
across the nrn Ohio River Valley today and tnt. The associated
sfc high pressure area will shift ewd across central WI this
morning then expanding into the lower Great Lakes late tnt.
This will yield light ely winds and cooler temps than yesterday,
but still above normal in the 70s. The upper ridge will then
re-orient more south to north across IL and WI for Mon-Mon nt
while the sfc wind fields do the same. This will boost high
temps back into the 80s away from Lake MI.

.LONG TERM...
Issued 300 AM CDT Sun Sep 28 2025
Monday night through Saturday:
Ridging in the polar jet looks to remain prevalent over our region
through the entire work week, favoring dry and quiet weather. GEFS
QPF plumes indicate that the soonest we could see the ridge break
down and mentionable rain chances re-enter the forecast is around
next weekend, and even then, it`s not a particularly strong signal.
As such, we have < 10% precip chances thru Friday unless things
change.
This same pattern favors above normal temperatures through the
period, with predominantly light east winds keeping lakeshore areas
cooler (in some cases, 3 to 7 degrees cooler than the values I`ll
discuss below) thru mid week, gradually veering south late this week
into this weekend. Daytime highs in the low 80s expected Tuesday,
with a slight lull in the heat possible Wednesday and Thursday
(upper 70s), then building back into the low 80s late this week
towards this weekend. This entire period would be considered 10 to
17 degrees above seasonal norms (which are 67 to 65 degree daytime
highs for Madison WI).

.MARINE...
Issued 300 AM CDT Sun Sep 28 2025
High pressure of 30.1 inches will move across central WI this
morning and to Lake Huron by early evening. Light and variable
winds are expected over central Lake Michigan this afternoon when
the high passes with light winds elsewhere. The high will expand
to the lower Great Lakes with surface ridging still extending west
into WI. Thus light winds will continue over the lake through
Tuesday. Winds will then become a bit breezy out of the east for
Tuesday night through Wednesday night when high pressure of 30.5
inches tracks from Hudson Bay to southern Quebec. A Small Craft
Advisory may be needed from Sheboygan to Winthrop Harbor
Wednesday night into Thursday morning for building waves.
