Area Forecast Discussion
National Weather Service Green Bay WI
450 AM CST Wed Nov 29 2017

Updated aviation portion for 12Z TAF issuance

.SHORT TERM...Today...Tonight...and Thursday
Issued at 234 AM CST Wed Nov 29 2017

Max and min temperatures in the nearly zonal flow the primary
forecast challenge. Temperatures will continue to run above
normal.

Northwest winds continue to pour a much cooler drier air mass
into the region early this morning. The combination of a short
wave trough sliding over the Northern Great Lakes region and the
northwest flow, were producing lake clouds over the UP. But drier
air were keeping the clouds north of the border early this
morning at this time.

A surface ridge sliding over the area today will produce plenty
of sunshine along with lighter winds.

The intrusion of dry air which poured into the area in the wake
of Tuesdays cold front has significantly lowered the chance for
precipitation tonight. Best Warm air advection arrives after
midnight ahead of another short wave trough sliding over the
Northern Great Lakes region, but mid levels saturation is brief.
Confined a small pcpn chance toward Lake Michigan and later
shifts may even remove that late today if trends continue to move
in that direction. Southeast winds off lake michigan tonight may
generate some lake clouds as surface dewpoints increase a bit.

Clouds with the short wave trough and flow off lake superior may
spread clouds over parts of northern wisconsin on Thursday,
otherwise more sunshine with a warm start Thursday morning will
produce max temps 5 to 10 degrees above normal.

.LONG TERM...Thursday Night Through Tuesday
Issued at 234 AM CST Wed Nov 29 2017

Generally dry conditions are expected across the area through much
of the upcoming weekend as the strongest mid level short wave
energy passes north of Wisconsin in low amplitude flow. High
temperatures should be in the neighborhood of 10 degrees warmer
than normal.

One system passing to the north of Wisconsin will bring a slight
chance for snow and/or rain to far north central Wisconsin Friday
evening, but the next chance for precipitation does not occur
until Sunday afternoon in warm advection ahead of an approaching
surface low. Model solutions really begin to diverge by early next
week, so precipitation timing and type are rather questionable by
the start of the new work week. Expect just rain for Sunday, but
precipitation Sunday night could be rain, snow, or a mix. Any
snow or mix will change to all rain during the day on Monday as
temperatures warm, but a transition back to snow or a mix may
occur before precipitation comes to an end Monday night.

.AVIATION...for 12Z TAF Issuance
Issued at 449 AM CST Wed Nov 29 2017

Ridge of high pressure building into the area today
will produce diminished winds and plenty of sunshine. Another
quick moving frontal system passing over the region tonight will
produce mainly mid level clouds and increasing southerly winds.

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