.SHORT TERM...
Issued 347 PM CDT Tue Apr 30 2024

Tonight through Wednesday night:

High clouds will increase late this afternoon and this evening
ahead of a frontal boundary and associated area of showers and
thunderstorms approaching from Iowa. We should mostly remain
dry through at least 8-9 PM, before precipitation arrives from
the west. Severe weather chances look low given very limited
instability by the time anything makes it into southern
Wisconsin, and it`s possible there is not even much in the way
of thunder is left by the precipitation arrives in the
Milwaukee area.

Precipitation should end by sunrise on Wednesday, with dry air
punching in behind the front. This will result in a quite a bit
of sun tomorrow, helping boost temperatures into the 70. West
winds will be quite breezy, with gusts of 25-35 MPH at times
during the mid day and afternoon hours.

High pressure builds in tomorrow night, with lows in the upper
40s and low 50s.

.LONG TERM...
Issued 347 PM CDT Tue Apr 30 2024

Thursday through Tuesday:

The baroclinic zone will sharpen up to our south on Thursday,
and begin to lift back north as a warm front during the day.
Showers and thunderstorms should expand in coverage north of the
front during the day Thursday, as low pressure lifts northeastward
through Kansas into Iowa and southern Minnesota. Some clusters
of surface based storms are possible by late afternoon and
evening, but at this point it looks like instability will be
limited. Overall, not expecting an organized severe risk, but a
few strong storms can`t be ruled out. Showers/thunderstorms
should end Thursday night or early Friday, with high pressure
building in Friday.

Our fast, active pattern continues with additional rain chances
Saturday as another shortwave sweeps through the area, followed
by another shot for precipitation on Monday or Tuesday.
Temperatures through this time period will generally be a
little above average, with highs in the low to mid 70s and lows
in the 40s and 50s.
