  through Monday. Snow showers and flurries can be expected
  Sunday afternoon and evening.

- A warming trend will push temperatures above normal the second
  half of the week.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 222 AM CST Sun Nov 9 2025

Much colder than normal temperatures will be seen across the area
today and tonight. Wind chills will remain in the teens today and
tonight except for being in the 20s this afternoon.

Lingering precipitation from the departing system will persist into
the first part of the morning mainly along/east of the Mississippi.
A secondary upper level disturbance will drop down into the area
this afternoon and evening. Steep low-level lapse rates should be
more than enough to generate flurries along with 20-30 percent
coverage of heavier snow showers.

Because of the cold upper low over Illinois, clouds will persist
through the day and be slow to break up tonight.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 222 AM CST Sun Nov 9 2025

Monday through Saturday
Assessment...A certainty (>99%) of a warming trend through the week

After another below normal day on Monday, a warming trend will
commence the remainder of the week as an upper level thermal ridge
builds into the Midwest. Temperatures by late week look to be 10 to
15 degrees above normal.

There will be a weak upper level disturbance moving through Monday
night as the stronger return flow develops. The system is very
limited on moisture so the most likely outcome is increasing clouds
to mark its passage. However, given the time of year I cannot fully
rule out some sprinkles or a few isolated showers.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 449 AM CST Sun Nov 9 2025

Light precipitation will continue past 12z/09 along/east of the
Mississippi where better forcing from the slow movement of the
departing system is located. A secondary upper level system
dropping south southeast from Minnesota will allow scattered
flurries and 20-30 percent coverage of snow showers to develop
across eastern Iowa and northern Illinois after 17z/09 and
persist through 06z/10.
