.SHORT TERM /THROUGH FRIDAY/...
Issued at 230 PM CST Thu Dec 4 2025

After record low temperatures for some locations this morning,
we`ll be a little "warmer" tonight due to steady southerly winds
limiting decoupling near the surface. Temperatures will likely
fall quickly this evening into early tonight, then slowly rise
late as the southerly flow becomes established. Latest forecast
has lows in the single digits above and below zero, coldest in
the eastern counties. Wind chills again will be quite cold with
min values in the single digits and teens below zero...brrr!

A mid-level shortwave will track across the Midwest on Friday
with an attendant surface trough expected to move through
eastern Iowa and northwest Illinois during the late evening to
overnight period. This system is moisture starved, but could
result in patchy light snow/flurries across the northern to
northeast counties, or even a little freezing drizzle due to a
loss of in-cloud ice (precip chances: 10-20%). Overall, it looks
like a low probability and little to no impact event.

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
Issued at 230 PM CST Thu Dec 4 2025

Saturday-Sunday: A clipper system is expected to impact the area
Saturday night into Sunday morning. NBM probabilities for
accumulating snow have continued to trend higher, now between
40-70% for 2"+ (roughly north of Highway 34). And the
probabilities for 4"+ are between 20-40% near and W/NW of the
Quad Cities. The EC ensemble has been consistent in showing a
band of 0.20-0.30"+ of QPF and other model guidance as been
trending toward the wetter and slightly stronger EC scenario.
Saturday`s forecast highs are in the mid/upper 20s, with colder
values in the teens/20s expected Sunday behind the clipper.

Early Next Week: Cold start to the work week Sunday night, with
another 1034mb surface high overhead. These temperatures will
not be as cold as the current air mass this morning, with 850mb
temps 4C warmer. Still could see a few locations with sub- zero
lows Monday morning. Two more clippers to track over the upper
Midwest (one Monday night-Tuesday and another 24hrs later) with
a general consensus keeping any appreciable snow potential north
across MN/WI. We would instead see a warm draw of above
freezing temps move into the CWA Tuesday and Wednesday, with a
rain/snow mix possible. LREF (100 member ensemble) is showing
40-70% probabilities of 850mb temps above 0C Tuesday and
Wednesday supporting above freezing highs. Continue to monitor
the forecast for any updates and trends with these passing
systems.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1140 PM CST Thu Dec 4 2025

A weak disturbance passing to our north is spreading clouds
across KCID, KMLI, and KDBQ with ceilings between 3 and 4 kft
tonight. KDBQ is expect to drop to at least 3 kft and remain
MVFR overnight. LLWS is forecast to develop at KCID and KDBQ
after 09 UTC and come to an end by 14 UTC as low level winds
increase. A cold front is forecast to move across the area late
this afternoon and into this evening with winds switching to the
west. MVFR ceilings are possible once again at KCID, DBQ, and
KMLI after 21 UTC Friday. FZDZ is possible at KDBQ and KMLI for
a brief period in the evening but confidence was low on the
timing and location so it was left out of the TAFs for this
issuance.
