.SHORT TERM /THROUGH TONIGHT/...
Issued at 112 AM CDT Sat Oct 3 2026

Northwest flow across the lower 48 with the jet stream passing
to our north from the Dakotas into the Upper Great Lakes. High
pressure that is currently centered over the Upper Mississippi
River Valley is forecast to shift eastward through this morning
with winds turning to the south by mid morning with speeds of 5
to 10 MPH and clear skies. Low humidity is in place across the
area with near normal high temperatures in the mid 60s to around
70 degrees.

Another shortwave moving through the flow is forecast to pass to our
north Saturday night into early Sunday morning. Moisture is very
limited and think that this will produce mainly mid to high
clouds across the area along and north of Interstate 80. Low
temperatures on Sunday morning are forecast to range from the
mid 40s in northwest Illinois to around 50 west of the
Mississippi River.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 112 AM CDT Sat Oct 3 2026

Northwest flow will persist aloft, leading to dry conditions for the
week. Following a dry frontal passage Sunday morning, the first half
of the week has high pressure overhead that will shift eastward
and turn winds from northerly ahead of the surface high to
southerly behind it. High temperatures will be in the mid 60s
to low 70s and lows in the 40s overnight. Come Wednesday, there
is another weak shortwave at upper-levels, which will lead to
another frontal passage. The chances for rain following the
passage are limited to less than 10% by the low moisture content
with dewpoints in the 50s at the surface and PWATS of less than
an inch. Upper level cloud coverage will increase and the winds
will shift back to northerly at the surface, but we will remain
dry. The high temperatures see a trend upward to mid 70s during
the day and mid 50s overnight for the later half of the week.
This is slightly warmer than normal by 5-10 degrees for this
time of year. All in all, this week will be a welcome quiet, dry
period to start October.

Issued at 1224 AM CDT Sat Oct 3 2026

High pressure is forecast to shift eastward through the TAF
period and bring VFR flight conditions to the area. A storm
system passing well to the north will spread mid level clouds
across the area early this morning with a second storm system
spreading clouds across the area after 00 UTC Sunday. Winds will
be light and variable overnight with south to southeasterly
winds through the day at 5 to 10 knots.
