.DISCUSSION...
Issued at 413 PM CDT Sun Sep 14 2025
Fog Trends...Fog is expected to develop again tonight and linger
into Monday morning. Overall, the 12z models came in with lower
probabilities for widespread dense fog across the forecast area, but
continue to focus on far northeast WI with the greatest potential.
Based on forecast soundings, the decrease in coverage appears to be
caused by "too strong" of winds in the boundary layer. That being
said, anticipate far northeast WI will see dense fog develop, with
patchy dense fog likely occurring in other locations in eastern WI.
Central and north-central WI may see patchy fog, but it will less
likely be dense. Any fog will burn off a few hours after sunrise.
Precipitation Trends...A strong ridge of high pressure will keep dry
conditions in the forecast through at least Tuesday. As the ridge
sags/shifts eastward on Tuesday/Tuesday night, a shortwave to the
north will attempt to bring a boundary and a 15-35% chance of
showers and storms to the UP and northern WI sometime between
Wednesday and Thursday. Meanwhile, models indicate an upper-level
trough developing over the Northern/Central Plains during this time,
which looks to be the main driver for any precip potential late this
week and into the weekend. Until the evolution of this trough
becomes clearer, low chances for precip will remain in the forecast
through the weekend.
Temperatures...The ridge of high pressure will continue to usher in
above normal temperatures through midweek, with highs mainly in the
upper 70s to mid 80s. Despite the above normal temperatures, they
will be far from nearing any records. With the pattern change
expected later this week, temperatures will cool back down to near
or slightly below normal with highs in the mid 60s to low 70s.

.AVIATION...for 18Z TAF Issuance
Issued at 1252 PM CDT Sun Sep 14 2025
VFR conditions are expected for the majority of the time
throughout this forecast period. The only exception being the
potential for low stratus/fog to develop late tonight into Monday
morning. However, the extent of the coverage looks to remain in
far northeast WI, but cannot rule out some patchy fog at the
east-central WI TAF sites and RHI. Any fog/stratus will lift soon
after sunrise, leaving good flying conditions for the remainder of
this TAF period and into Monday afternoon.
