Area Forecast Discussion
National Weather Service Green Bay WI
803 AM CDT Sun Sep 3 2017

New Information added to update section

.UPDATE...
Issued at 802 AM CDT Sun Sep 3 2017

Fog has mixed out and visibilities have improved considerably, so
will let the dense fog advisory expire.

&&

.SHORT TERM...Today...Tonight...and Monday
Issued at 418 AM CDT Sun Sep 3 2017

areas of low clouds and fog will continue until shortly after
daybreak, then skies should become partly sunny. Warm advection
should produce high temperatures about five degrees above normal
for this time of the year. Clouds will increase tonight as an
upper trough and weak surface cold front approach from the
northwest. The best upper forcing is to the north, where the best
chance of showers and thunderstorms will be.

Any leftover showers in eastern Wisconsin early Monday will end
quickly, with partly sunny and slightly cooler air arriving on
northwest winds.

.LONG TERM...Monday Night Through Saturday
Issued at 418 AM CDT Sun Sep 3 2017

An amplifying pattern across North America will lead to below normal
temperatures for much of the period.  Models disagree towards late
next week in regards to how quickly the eastern noam trough lifts
off to the northeast, and consequently, how fast warmer air returns
to the region.  Will continue to use a multi-model blend for this
forecast.

Monday night through Tuesday night...Shortwave energy will be
sliding across the region as the eastern noam longwave trough
amplifies overhead.  These shortwaves will bring scattered light
showers, mainly to northern WI where moisture will be the deepest. A
more vigorous shortwave will arrive on Tuesday, which will have help
from  diurnal instability to bring a chance of showers to all
locations.  Enough moisture will linger into Tuesday night beneath
the trough axis to continue the shower threat over northern WI. With
the clouds and cold advection during this period, temps will be much
cooler than Mondays readings.

Rest of the forecast...The upper trough will linger over the eastern
half of the state on Wednesday, with coverage of showers likely
spreading with heating of the day.  But then we finally get to the
backside of the trough by Thursday, which should result in dry
weather and a slow warming trend into next weekend. Frost remains
possible, mainly over northern WI, for both Wed and Thu nights.
&&

.AVIATION...for 12Z TAF Issuance
Issued at 636 AM CDT Sun Sep 3 2017

Areas of low clouds and fog should dissipate by 14z,
with good flying weather expected this afternoon and evening.

Low level wind shear is expected tonight as southwest winds
increase ahead of a frontal system. As the front moves through
there is a chance of showers and isolated thunderstorms over
northern Wisconsin late tonight.

MVFR ceilings possible late tonight through midday Monday, then
VFR weather will return in the afternoon and continue Monday
night.

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
