Area Forecast Discussion
National Weather Service Green Bay WI
219 PM CDT Mon Aug 10 2020

Forecast discussion for routine afternoon forecast issuance

.SYNOPSIS...
Issued at 210 PM CDT Mon Aug 10 2020

Scattered thunderstorms ending by early evening, then sunny and
much less humid by tomorrow. Above normal temperatures continuing
into the upcoming weekend.

Throughout the forecast period, the subtropical ridge will remain
stretched out across the central and southern CONUS while a
seasonably strong band of westerlies persists across Canada and
the far northern CONUS. The westerlies will gradually gain
a little amplitude and become slowly progressive during the
middle to latter part of the period.

Temperatures should remain slightly to modestly above normal
throughout most of the period, then drop back late. Discounting any
heavy rainfall from convection late this afternoon, precipitation
will be likely be AOB normal for the period.
&&

.SHORT TERM...Tonight and Tuesday
Issued at 210 PM CDT Mon Aug 10 2020

Convection has been slow to organize across the area, But with
gradual recovery from the morning storms continuing, and shear
increasing, severe storms will be possible in the east until the
front clears the area late this afternoon or early this evening.
We are also monitoring for the possibility that the storms moving
over the northern Bay of Green Bay will result in a wave of water
propagating down the bay. The ideal situation for that to happen
would be if the storms were moving faster, but given the high
lake/bay levels it doesn't take much displacement of water to
result in flooding of low areas near the shoreline.

Quiet weather is expected overnight and Tuesday as a weak
anticyclone slowly shifts into the region.

.LONG TERM...Tuesday Night Through Monday
Issued at 210 PM CDT Mon Aug 10 2020

The quiet weather will persist well into the long-term portion of
the forecast. Overall, saw no reason to deviate significantly
from the standard forecast initialization grids generated from a
broad-based blend of guidance products.
&&

.AVIATION...for 18Z TAF Issuance
Issued at 1233 PM CDT Mon Aug 10 2020

A cold front will sweep across the area this afternoon, generating
scattered showers and thunderstorms. The greatest chance for
thunderstorms will be in east-central Wisconsin, so carried in the
TAFs there. Skies will clear in the wake of the front. Some fog is
possible late tonight, especially in central Wisconsin.

.GRB WATCHES/WARNINGS/ADVISORIES...
