.SHORT TERM...
Issued 338 AM CDT Tue Sep 23 2025
Today and Tonight:
There is a chance for some fog to develop early this morning as
high level clouds begin to clear out of the area. An isolated
storm or two will also be possible early this morning as some
moisture an instability linger behind a departed front.
Otherwise, any additional shower/storm development today is
expected to be mainly south of the WI/IL border, with the
surface boundary south of the state line. Some of this activity
may sneak into far southern Wisconsin today, depending on where
exactly the front settles by the afternoon. Thus kept 15-30%
chances near the state line. Temps will be a little cooler today
behind the front, with highs in the lows to mid 70s most
places.
Latest models suggest an increase in low cloud coverage
tonight, as a cooler airmass settles in from the north. Dry
weather is likely overnight, with lows in the mid to upper 50s.

.LONG TERM...
Issued 338 AM CDT Tue Sep 23 2025
Wednesday through Monday:
Weak surface low pressure over western portions of the Ohio River
valley on Wednesday will result in a modest northeast breeze
across the region, holding daytime high temperatures to around 70
degrees. A few rainshowers may occur Wednesday and Thursday,
primarily south of the US-151 highway corridor, as the
aforementioned low pressure tracks northeastward and deepens. This
rain should be brief and light if applicable. Northeast winds
decelerate and back northwest throughout Thursday as low pressure
ejects into Canada, allowing cloud cover and precip chances to
diminish.
Dry weather is looking likely late Thursday through the rest of
the forecast period. Two low pressure systems traverse southern
Canada in this window, but model guidance currently holds all
associated precip well north of our region. High temperatures
climb back towards the upper 70s late this week into this weekend
as a longwave ridge in the jet stream builds over the northern
Rockies and upper midwest.

likely developing as a cooler airmass settles in from the north.

.MARINE...
Issued 338 AM CDT Tue Sep 23 2025
Areas of fog will persist through early this morning across
roughly the northern half of the lake. Will continue to monitor
trends to see of the Dense Fog Advisory will need to be extended
beyond 7 AM CDT.
Northerly winds will pick up this afternoon through Wednesday as
high pressure around 30.2 inches forms near the Hudson Bay and low
pressure around 29.8 inches develops in the middle Mississippi
Valley. The low will slowly pass near or just southeast of
southern Lake Michigan later Wednesday through Thursday. Wind
gusts are expected to remain below gale thresholds during the
low`s approach and passage.
