Area Forecast Discussion
National Weather Service Green Bay WI
245 PM CDT Fri Aug 25 2023

Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Saturday
Issued at 244 PM CDT Fri Aug 25 2023

The latest RAP analysis and satellite/radar imagery show cold
front dropping southeast across western Lake Superior an about to
move into northwest Wisconsin early this afternoon. Convergence
and instability along the front with surface based instability
upwards of 1000-1500 j/kg. Deep layer shear is robust at 50-60 kts
with relatively long and straight hodographs. However, while
showers and storms have already developed and are approaching
north-central WI, they have been low topped so far with echo tops
up to 25 kft. A few gusts to 40 mph have been observed in the
surface obs already, and think 40-50 mph gusts is about what can
be expected as the storms move in to north- central WI late this
afternoon and northeast Wisconsin this evening. Forecast concerns
mainly revolve around thunderstorm potential and timing tonight
followed by cloud/wind trends on Saturday.

Tonight...A strong shortwave will rapidly push the front southeast
across the region during the evening. A narrow zone of surface
based instability will gradually dissipate as nocturnal cooling
sets in. As a result, storm intensity will be near peak or have
already peaked as isolated to scattered storms slide southeast
across northeast to central WI. Think the chance of gusty winds
will persist in the strongest storms as they weaken, though, as
high dcapes will promote gusty winds to reach the surface. Will
keep a mention of gusty winds and small hail in the HWO.

The chance of storms will depart by late evening with winds
veering to the north. The north winds will advect low stratus (currently
north of Lake Superior on satellite imagery) across the region in
low level cold advection. Moisture depth does not look deep enough
for showers or drizzle, so lowered precip chances somewhat, but
did not remove them completely. North to northeast winds will
increase late and become gusty to 25 mph over northeast WI. Lows
in the 50s to low 60s.

Saturday...Widespread low broken to overcast skies will likely be
present during the morning with a few spits possible over
northeast WI. Then incoming dry air with a surface high should
help mix out the clouds by mid to late afternoon. Temperatures
have cooled a few degrees in this forecast cycle with highs
ranging from the middle 60s to lower 70s.

.LONG TERM...Saturday Night Through Friday
Issued at 244 PM CDT Fri Aug 25 2023

High pressure overhead will provide mostly clear skies and light
winds Saturday night, with ideal radiating conditions across
northeast Wisconsin. This will allow temperatures to tumble
through Sunday morning, with lows ranging from the upper 30s to
lower 40s across the north and around 50 across east-central
Wisconsin. Some patchy frost is possible across portions of
north-central Wisconsin Saturday night and Sunday morning,
especially across the cold prone areas.

The high will slowly drift southeast through the early part of
next week, allowing temperatures to moderate a bit as temperatures
return to around normal by Monday. A slow moving cold front will
bring showers to the area Monday afternoon through Tuesday as it
tracks through the area along with some rumbles of thunder.
Thunderstorms with this cold front are not expected to be severe
given the lack of instability and shear.

High pressure will build in behind the departing front Tuesday
night, and linger across the area through Thursday. This will
bring a stretch of dry and quiet weather to the region as well as
below normal temperatures.

A weak cold front will bring the chance for showers back to the
area Thursday night into next Friday; however, the front weakens
quite a bit as it tracks through the region so it is possible it
comes through mostly dry. Warm air advection ahead of the front
will allow temperatures to return to around normal by the end of
next week.

.AVIATION...for 18Z TAF Issuance
Issued at 1155 AM CDT Fri Aug 25 2023

Scattered to broken MVFR ceilings persist across parts of central
to northeast Wisconsin early this afternoon. The low CIGS are
expected to rise into the VFR category and scatter in the early to
middle afternoon hours.

Meanwhile, a broken line of showers and thunderstorms are expected
to move across the area late this afternoon into this evening,
which are still timed similar to the previous TAF forecast. Gusty
winds to 40 kts will be possible in the strongest storms. Added a
tempo group to RHI and GRB where there is the highest probability
of storm occurrence. Most storms should exit by late in the
evening.

After midnight, north to northeast winds will bring in low
stratus (MVFR to IFR) to much of the area. There may be some
light rain across the far north, and across portions of northeast
Wisconsin late tonight into Saturday morning. The low clouds will
be slow to clear Saturday morning across northeast Wisconsin.
&&

.MARINE...
Issued at 244 PM CDT Fri Aug 25 2023

Gusty northeast winds behind a cold front will develop
late tonight into Saturday morning. Gusts of 20 to 25 kts and
waves up to 4 ft will be possible, peaking mid-morning to early
afternoon. Small craft are urged to use caution. A small craft
advisory may be needed.
