Area forecast discussion, Jul 13, 3:27 PM CDT, 1 hour 32 minutes before
Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
327 PM CDT Mon Jul 13 2020

.SHORT TERM...

Tonight and Tuesday - Confidence...Medium to High

Mid level and surface ridging dominate tonight. Diurnally driven
CU field will dissipate with the loss of heating. Lake breeze has
brought corridor of clear air westward from the lake. The surface
and mid level ridging shifts eastward into Tuesday. We will see
the southerly flow increase tapping into some higher moisture.
With the mid level flow becoming more wsw some vorticity will be
drawing closer to northwestern fringes of the area as the day
wears on. The northeast/southwest lower level convergence zone is
proggd to remain to the northwest of the area so some of the
slower solutions on precip advancement have some merit.

.LONG TERM...

Tuesday Night through Sunday Night...Forecast confidence is
moderate to low.

A cold front will slowly sink southeastward Tuesday night. Storms
in the west may be potentially severe, but will likely decrease in
strength and coverage as they approach southern WI overnight. The
front will slow, and then as a 500mb shortwave approaches from
the west Wednesday morning, convection will likely perk up again
for a second round during the afternoon on Wednesday. High
pressure will then build in behind the system and dry conditions
out for Thursday.

Friday into the weekend, a large-scale ridge should build in and allow
for warmer temperatures. The GFS has consistently been holding
off on higher temperatures (95+), but the ECMWF has been flip-
flopping on temperatures, having them skyrocketing into the mid to
upper 90s with one run and then trending back toward the GFS with
the other. We'll continue to watch the heat potential for this
upcoming weekend. One thing that is consistent is the possibility
for intermittent t-storm activity for S WI as complexes form and
ride the top of the ridge.

 &&

.AVIATION(21Z TAFS)...

VFR CU field will erode this evening with
loss of heating. Otherwise VFR this period with more fog potential
later tonight in Wisconsin River Valley. Tuesday looks mainly dry
though some shra/tsra could sneak into the northwest sections of
our area in the afternoon.

&&

.MARINE...

Breezy southerly winds will develop for Tuesday and continue
through Tuesday night ahead of a low pressure system. The northern
nearshore zone is a close call for a small craft but will hold
off at this time. Winds will be lighter Wednesday, but shift to
the northwest Wednesday night as a front moves through.
