.SHORT TERM /THROUGH TONIGHT/...
Issued at 154 AM CDT Wed Oct 1 2025
Satellite imagery early this morning shows cloud cover across
the region with high pressure sitting to our northeast producing
east winds around 5 MPH. Temperatures at 2 AM range from 57
degrees at Sterling Rockfalls to 68 degrees at Keokuk.
Little change in the forecast for today as the region remains
on the western edge of high pressure associated with the
blocking pattern. Partly sunny skies are expected today as mid
and high clouds drift across the area associated with a storm
system passing to our north. Cooler high temperatures are
expected for today with high temperatures largely in the lower
80s north of a Cedar Rapids to Clinton to Sterling Rock Falls
line and mid 80s to the south. Winds today are forecast to
become more southeasterly at 5 to 10 mph.
Skies are forecast to slowly clear from west to east Wednesday
night. Low temperatures are forecast to be in the mid to upper
50s.

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 154 AM CDT Wed Oct 1 2025
High pressure and Blocking will shift to the east to end the
week with southerly flow developing across the region. This will
draw warmer air back into the area as well as some moisture.
Warm air advection and mixing is forecast to push high
temperatures back into the upper 80s to near 90 degrees. The
warmest temperatures are expected on Friday and Saturday with
forecast high temperatures within 3 to 4 degrees of daily
records.
Models continue to show deep troughing across the western US
slowly moving eastward Saturday into Sunday and pushing broad
high pressure to the east. The important question is how quickly
this trough moves eastward into the Plains and how much
moisture is pulled northward into the region. The NBM continues
to produce 25 to 35 percent chances of rain and potentially
storms ahead of a cold front Sunday night into Monday. There is
lower confidence in the timing of precipitation as model vary by
12 to 24 hours in the timing of this storm system.  Once the
front moves through, cooler air is forecast to move into the
area.
