.DISCUSSION...
Issued at 130 PM CDT Mon Oct 6 2025
> OVERVIEW: surface cold front currently laying out from SE WI into
central IL will exit southeast later tonight. Cyclonic flow a loft
persists for Tue before upper level ridging builds in from the
plains. The GEFS and EPS remain adamant that a shortwave trough will
drop southeast out of Canada and across the ridge axis Thu night/Fri
morning. Some differences over the past few days on
placement/strength, but latest favored track would bring it across
the local forecast area. The ridge reestablishes itself for the
weekend. Long term guidance not favoring a blocking pattern, rather
the flow is looking more progressive moving into next week.
> RAIN CHANCES: sfc cold front currently laying out from southeast
WI southwest across central IL. Showers continue to spark along the
front, moving northeast. Bits of shortwave energy were moving
northeast out of the plains/IA and will work across the boundary
this afternoon into early evening - and expect some increase in
areal coverage of the rain as this occurs. CAMS trending toward
expanding northward into the I-94 corridor. Thunder threat looks
minimal to none with the instability pool south of the cold front.
The Thu night/Fri morning shortwave will bring the next shot for
rain. Not a lot of QPF currently indicated with the Grand Ensemble
painting only 5 to 15% chances for greater than 1/10". Limitation on
saturation a main drawback. Model blend holds the low end pops (20-
30%) which look reasonable at this time.
> TEMPERATURES: seasonably cool the next couple days as colder
(comparatively) air flows in post the cold front and northwest flow
a loft persists. By mid week, with the advent of ridging a loft,
temps will be back on the rise, which should continue into the
weekend. 75% of the GEFS/EPS ensemble members favor highs from the
upper 60s to mid 70s - with Sunday currently shaping up as the
warmest of the bunch. About 5% of the members suggest 80 could be
reached at a few locations.
But before we get there, clear skies and light winds Tue night could
drop temps to freezing across the I-94 corridor northward (25-50%
chances via the LREF). Frost/Freeze headlines may be needed in these
areas.

Issued at 1225 AM CDT Tue Oct 7 2025
Scattered showers across northeast Iowa and southwest and
central Wisconsin will gradually shift southeast out of the area
overnight. From today into tonight, high pressure will build
southeast across the Upper Mississippi River and western Great
Lakes. This high pressure area will produce light winds and
mainly clear skies.
