Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
855 AM CDT Sat Jul 22 2023

.UPDATE...
(Issued 855 AM CDT Sat Jul 22 2023)

Isolated pops-up still look plausible this afternoon as CAPE
levels build. All in all going forecast in good shape.

.SHORT TERM...
(Issued 316 AM CDT Sat Jul 22 2023)

Today through Sunday night:

A shortwave trough currently passing through srn WI will exit a
little later this morning. A rogue shower will be possible until
it does so. Additional chances for showers and storms will develop
for this afternoon and tnt via the lake breeze today, and a
shortwave passage and weak sfc trough tnt. High temps will once
again reach the lower 80s.

The shortwave trough will exit Sun AM but another weak trough is
expected late, while the lake breeze may be enough to trigger a
shower or storm as well. Only slight chances for pcpn while temps
will warm into the lower to middle 80s.

.LONG TERM...
(Issued 316 AM CDT Sat Jul 22 2023)

Monday through Friday:

The upper ridge over the Desert SW is expected to expand ewd into
the central USA during this period. This will result in nwly flow
transitioning to more zonal with higher 500 mb heights over the
area. Nevertheless, weak shortwave troughs will remain in the
upper flow with continued chances for showers and storms, albeit
small on most days. The high heights and warm, moist advection
will warm sfc temps into the lower to middle 90s for Wed-Thu
inland from Lake MI, with heat index values several degrees
warmer. A weak cold front may then pass on Fri.
