Area Forecast Discussion
National Weather Service Green Bay WI
212 PM CDT Sat Jun 3 2023

Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Sunday
Issued at 212 PM CDT Sat Jun 3 2023

The weather in the short term will look fairly similar to the past
couple of days, as the retrograding ridge aloft inhibits any
major airmass exchanges.

Temperatures this morning rose quickly under sunny skies from the
lower 60s to the lower and mid 80s by this afternoon. This has
brought us to our convective temperatures, producing a cumulus
field over much of north-central to northeastern Wisconsin. The
first few storms have also formed along the Upper Peninsula
border.

The overall storm threat will be similar to the last couple days
as well, relying mainly on surface based heating and instability.
With little in the way of shear or upper support, storms will
likely be slow moving in nature, and fairly pulse-like. The main
initial focal point for convection will be across the north today,
where surface wind fields do show some convergence between winds
off the lake and winds from the Upper Peninsula. Unlike the past
couple of days, surface flow is generally from the east, which
will not favor boundary formation near the lake from a lake
breeze. If an organized cold pool forms like storms did
yesterday, this will likely serve as the focal point for any
convection. Hail will be the initial concern, as a couple reports
already include potential for half inch hail. That said, the
higher bases and dry air below will help melt any hail as it
falls, potentially reducing the impact of any larger stones in the
region. Wind will be a concern as a result as well, as the
inverted v soundings do have some potential to produce some
stronger gusts as storm towers collapse.

As we get into the late evening, any storm threat will quickly
diminish again as the surface cools. There is at least a small
concern for the development of ground fog again tonight, mainly in
the areas where rain passes today. The main factor against fog
however will be the drier dewpoints forecast for overnight, so
left it out of the grids for now.

In fact, the drier and slightly cooler air in the forecast will
help establish surface high pressure over the area for Sunday.
This should inhibit additional storms developing tomorrow, despite
temperatures getting back into the lower to upper 80s.

.LONG TERM...Sunday Night Through Saturday
Issued at 212 PM CDT Sat Jun 3 2023

A cold front will track through the western Great Lakes on
Monday, which will bring the chance for showers and maybe a few
thunderstorms as it tracks through the region. NWP models are a
bit less optimistic about precipitation chances as this front
moves through the area, especially across east-central and
northeast Wisconsin. Model soundings show quite a bit of dry air
as the front moves through the area on Monday; therefore,
precipitation chances have been lowered as this front sinks south
through the area.

Behind the cold front, a Hudson Bay high pressure system will
build south across the western Great Lakes region by the middle of
the week and sink further south over the Ohio Valley by the end
of the week. The high will usher in a cool, dry airmass across
the region with highs limited to the 70s and overnight lows in the
40s and 50s. Temperatures will slowly warm by the end of the week
as the high slides south and highs recover to around 80 degrees.

Return flow on the backside of the high along with an approaching
cold front will bring the chance for showers Friday into early
next weekend.

.AVIATION...for 18Z TAF Issuance
Issued at 105 PM CDT Sat Jun 3 2023

Main aviation concern will be the development of some high base
showers and thunderstorms across northern Wisconsin this
afternoon. Main area expected to be impacted will be RHI, so a
mention was made for the afternoon to evening hours. Confidence
was lower as to how far south any storms would spread, so kept
mention out of the central WI TAF sites. VFR conditions are
expected outside of the storm threat, but brief lower visibility
is possible in any heavier downpours. Any convection will
dissipate overnight, but a small chance for ground fog returns
overnight for RHi as well, especially if rain crosses the area
this afternoon. Much quieter weather and good flying conditions
are anticipated for Sunday.

.GRB WATCHES/WARNINGS/ADVISORIES...
