Area Forecast Discussion
National Weather Service Green Bay WI
236 PM CDT Sun Aug 5 2018

Forecast discussion for routine afternoon forecast issuance

.SYNOPSIS...
Issued at 233 PM CDT Sun Aug 5 2018

Continued warm and humid with periods of showers and
thunderstorms through tomorrow, then quieter weather for the rest
of the upcoming work week.

The upper pattern will transition from a zonal band of westerlies
along the U.S. Canadian border to a more amplified regime
(especially out west) during the period. The amplification will be
driven by the development of a strong ridge north of a closed
upper anticyclone strengthening over the intermountain West. The
ridge will progress east and take on a more SW-NE orientation,
extending toward Hudson Bay late in the period. Downstream
troughing will develop in response to the building ridge, though
the downstream trough is forecast to remain rather weak.

Significant rains are possible early in the period, especially
across the southern part of the forecast area. Subsequent
events during the remainder of the period are more likely
comprised of scattered convection with light amounts. The warm and
very humid air mass presently across the area will shift off to
the southeast. But the lack of strong northwest flow into the
eastern NOAM upper trough does not favor a major intrusion of
Canadian air into the area. So temperatures will probably remain a
little above seasonal normals for most of the period.
&&

.SHORT TERM...Tonight and Monday
Issued at 233 PM CDT Sun Aug 5 2018

Convective trends are again the focus of the short-term portion of
the forecast. A potentially volatile situation is evolving in
north-central Wisconsin, where MUCAPES are now 3-4K J/kg and
deep-layer shear around 50 knots. The convective temperature has
been reached, with the Cu field looking rather agitated. The main
negative is that the area is probably still under the influence of
subsidence behind the shortwave that crossed the area this
morning.

A second area of concern is central and east-central Wisconsin.
At mid-day, water vapor imagery indicated a strong shortwave
heading east from the intermountain west. That will probably help
initiate an MCS to our west, which will probably cut across the
southern portion of the forecast area late tonight or Monday
morning. Those storms would pose primarily a wind threat, but also
could produce torrential rains that result in localized flooding.
Thunderstorm chances should begin to decrease from the northwest
on Monday afternoon.

.LONG TERM...Monday Night Through Sunday
Issued at 233 PM CDT Sun Aug 5 2018

A high pressure ridge will amplify over the western half of the
U.S. by midweek and the flow aloft will shift from west-east to
northwest-southeast for Northeast Wisconsin. The ridge will
expand well into Canada and begin to spread east toward the Great
Lakes later in the week. Before the ridge moves in, a cold front
will sweep into the Northern Midwest, currently progged to reach
our area during the first half of the day Thursday. After the
front pushes through, conditions should be relatively dry for
several days.
&&

.AVIATION...for 18Z TAF Issuance
Issued at 1231 PM CDT Sun Aug 5 2018

The main aviation weather concern is thunderstorms. The best
chance for storms will probably be tied to the arrival of a
vigorous shortwave trough late tonight through Monday morning, and
be focused across central and east-central Wisconsin.  But enough
destabilization could still occur this afternoon to support late
afternoon/evening storms across the north. Primarily VFR
conditions are expected outside of the storms.

...THUNDERSTORMS EXPECTED TO DEVELOP ACROSS NORTH-CENTRAL AND FAR
NORTHEAST WISCONSIN DURING THE LATE AFTERNOON HOURS...

Thunderstorms are expected to gradually increase across north-
central and far northeast Wisconsin during the late afternoon
hours. The strongest storms are likely to produce hail, gusty
winds, and brief heavy rain. Lightning with the storms will pose a
hazard to boaters on area lakes, as well as anyone engaged in
outdoor activities.

If outdoors when a thunderstorm approaches your area, consider
seeking shelter inside a building. If you are boating and in the
path of a storm, head for shore and move indoors or inside a
vehicle. Remember, lightning can strike out to 10 miles from the
parent thunderstorm. If you can hear thunder, you are close enough
to be struck by lightning. Do not be caught on the water in a
thunderstorm.
