.SHORT TERM...
Issued 210 PM CDT Fri Sep 26 2025
Tonight through Saturday night:
Stratus deck behind the backdoor cold front halted and will
continue across east central WI for the remainder of the
afternoon. Rest of southern WI is experience sunshine and temps
warming into the upper 70s and low 80s. Cooler temps and calm
winds are expected into the overnight hours. The lingering cloud
deck across east-central WI may spread south and inland
overnight and may be accompanied by patchy to areas of fog
development given the light winds and increased low-level
moisture with a quick passing surface high. Fog would linger
into Saturday morning before lifting after daybreak as warmer,
southerly winds gradually pick up into the afternoon. Looking
at summer-like temps for Saturday with high creeping into the
low to mid 80s for Saturday afternoon.
Meanwhile a mid-level shortwave trough and surface low is
progged to traverse across Ontario through the day. As it
pushes further east the associated cold front is progged to
drift southward across southern WI Saturday evening/night.
However, given the dry conditions not expect any precip
associated with this frontal passage and mainly will see a
westerly wind shift along with a cooler airmass as high
pressure begins to build in overnight. Looking at lows Saturday
night into Sunday morning in the mid 40s to lower 50s.

.LONG TERM...
Issued 210 PM CDT Fri Sep 26 2025
Sunday through Friday:
Continue to see the surface high build into the Great Lakes
Region for Sunday and slowly progress east through the start of
next week. Will also see an upper-level ridge sets up across the
Upper Midwest and linger into the middle of next week.
Accompanying this pattern will be temps gradually warming each
day from mid 70s Sunday into the low/mid 80s Monday/Tuesday.
Looking at another high pressure system to build down from
Canada by midweek and bring more easterly winds, which could
result in cooler temps midweek onward. However, this will also
be dependent on the tropical systems in the Atlantic and their
tracks as the slower solutions would enhances our
easterly/cooler flow, but if the more progressive model
materializes, southern WI may end up warmer than the current
forecast keeping the easterly winds further north.
Overall, looking at a dry, fairly inactive pattern (no rain
chances) with near to above normal temps this weekend through
the middle of next week.

.AVIATION...
Issued 210 PM CDT Fri Sep 26 2025
Stratus deck and MVFR flight conditions held up across east-
central WI this afternoon limiting impacts just to SBM. Rest of
southern WI terminals will experience VFR conditions through the
remainder of the afternoon and into the early evening. However,
models are progging this cloud deck to become more progressive
overnight into Saturday morning as high pressure quickly skirts
through the area. This may end up bringing lower ceilings
(between VFR/MVFR) along with patchy fog to inland terminals.
Still some concerns about how widespread these impacts will be,
but MSN, JVL, and UES have a higher potential to see lower
flight conditions as a result. While SBM, MKE, and are less
likely, they may end up seeing some patchy fog as well, just not
as confident closer to the lakefront at this time. Otherwise,
conditions are progged to improve through Saturday morning as
warmer, southerly winds gradually pick up ahead of dry cold
front passing through the area late Saturday afternoon/evening.

.MARINE...
Issued 210 PM CDT Fri Sep 26 2025
High pressure will quickly skirt across Lake Michigan this
evening/overnight bringing lighter winds. High pressure will
trek into Quebec by Saturday morning, while sub-1000mb low
pressure tracks across northern Ontario through the day
Saturday. Will see more southerly winds gradually pick up ahead
this system`s dry cold front, which will push across the Upper
Great Lakes late Saturday afternoon into the overnight. Another
high pressure is expected to quickly build in behind this
frontal passage for Sunday with lighter and variable winds. Will
see this high pressure gradually work eastward through the
start of next week with a return of southerly winds Monday and
Tuesday. Easterly winds may return toward the middle of next
week as another stronger high pressure builds down across the
Great Lakes region.
