Area Forecast Discussion
National Weather Service Green Bay WI
631 PM CDT Sat Jul 20 2019

Updated aviation portion for 00Z TAF issuance

.SHORT TERM...Tonight and Sunday
Issued at 346 PM CDT Sat Jul 20 2019

Much quieter weather will settle across the region tonight. The
primary frontal boundary will continue to sag to the south.
The lingering showers and thunderstorms across the area will
diminish and end, but will carry low PoPs into the night in case
some redevelopment within the frontal zone occurs overnight. Some
of the guidance was hinting as scattered showers tomorrow as the
RRQ of a speed max crosses the area. Kept forecast dry for now,
but that will need to be watched.

.LONG TERM...Sunday Night Through Saturday
Issued at 346 PM CDT Sat Jul 20 2019

The upper flow tilting northwest will bring a seasonably strong
and rather large anticyclone south from Canada. The high will
linger across the area for several days. The associated air mass
will have seasonable temperatures and much lower humidity. The
temperature and humidity may begin to creep up late in the period
as the high shifts off to the east.

.AVIATION...for 00Z TAF Issuance
Issued at 631 PM CDT Sat Jul 20 2019

Showers and thunderstorms have come to an end across the TAF sites
this evening. The lingering issue is some MVFR cigs across central
Wisconsin which should dissipate in the next few hours. Otherwise
VFR conditions are expected during the TAF period as a ridge of
high pressure builds in across the western Great Lakes region.
Winds will generally be light overnight with some fog possible.
However confidence is not high enough to include in this set of
TAFs given the extensive upper level cloud shield in place.
