.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 135 AM CDT Fri Oct 2 2026

Post-frontal airmass takes over after a prolonged stretch of wet
weather, with surface high pressure building over the region. We
will see cooler temperatures in the 60s, clear skies, and light
northeast winds through the day. Widespread temperatures in the
40s tonight, with light east-northeast winds.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 135 AM CDT Fri Oct 2 2026

Zonal to northwest flow will set up in the upper levels over the
weekend with a couple of shortwave troughs coming through Saturday
evening and again Wednesday. Low moisture content will mean these
frontal passages will be dry with an increase in upper level clouds
and a northerly shift in the winds being the main impacts.
Otherwise, skies will be mostly clear and winds should remain light
with high pressure setting in for the week. Temperatures will be
seasonable with highs in the 60s to 70s and lows in the 40s to 50s
through Tuesday. The shortwave features on Wednesday will bring some
warm air advection from the Desert SW which will increase temps a
bit through the later half of the week, with highs in the mid 70s
and lows in the mid 50s.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1217 AM CDT Fri Oct 2 2026

We will continue to see low clouds move out of the area from
northwest to southeast, with CID/DBQ already seeing VFR
conditions. MVFR cigs are still being seen at MLI/BRL, but will
improve by 09z. From there, VFR conditions will prevail through
the remainder of the TAF period. North to northeast winds of
5-10 KTs can also be expected through Friday. Otherwise, no
other sig wx is expected at this time.

.HYDROLOGY...
Issued at 1231 PM CDT Thu Oct 1 2026

Now that we`ve seen where most of the rain has fallen and how rivers
are beginning to respond, many of the river forecasts have been
adjusted downward since yesterday. While all rivers and creeks are
responding to the rainfall, we are no longer expecting flooding
along the Rock River nor along the Mississippi River. Some of the
rivers that do flood may remain above flood stage for several days
before receding due to the widespread stratiform nature of this
rainfall.
