.SHORT TERM...
Issued 318 PM CDT Sun Sep 15 2024

Tonight through Monday night:

A few cumulus clouds developed this afternoon in the west where
dewpoints didn`t quite mix out enough. Temperatures are around
80 near the lakeshore where there is an easterly wind component
off the cooler lake, and upper 80s to around 90 in inland
areas. Lows tonight will be in the lower 60s, similar to last
night, with mostly clear skies.

There is supposed to be an aurora event late tonight, so
viewing should be ok if the cirrus can hold off or remain thin
enough. Light winds and dewpoints in the lower 60s could allow
for some patchy fog in low spots once again.

Temperatures tomorrow will basically be a repeat of today. Mid
and upper levels will be slightly drier than today as that upper
ridge retrogrades a bit. Therefore, dewpoints should be a little
cooler and diurnal cumulus clouds should be even more sparse.
Monday night lows are forecast to be in the upper 50s to around
60.

.LONG TERM...
Issued 318 PM CDT Sun Sep 15 2024

Tuesday through Sunday:

Ridging and dry weather is going to hold over the eastern Great
Lakes and Lake Michigan through at least Thursday night. We do
not have any slight chance of rain in our forecast until early
Friday morning and that is limited to west of Madison. Our
extended forecast for next weekend brings in low chances (20 to
30 percent) of showers for Madison and west at times. There is
low confidence for when the front will actually cross WI and
that front may hold off until next week.

.AVIATION...
Issued 318 PM CDT Sun Sep 15 2024

Patchy fog is possible in the typical low spots again tonight.
Otherwise, expect VFR conditions to prevail due to dry air over
the region. Diurnal cumulus clouds with bases of around 7000 ft
are possible once again tomorrow.

.MARINE...
Issued 318 PM CDT Sun Sep 15 2024

High pressure around 30.3 inches over the eastern Great Lakes
and low pressure around 29.8 inches over the Plains will remain
fairly stationary over the next several days. The high will
weaken to 30.0 inches and the low will strengthen to 29.6 inches
by Thursday. Winds over Lake Michigan will remain out of the
south to southeast through this time, and generally be less
than 15 kt. It is uncertain about when a front will move across
Lake Michigan, but low pressure is expected to approach
Wisconsin next weekend.
