.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 204 PM CST Thu Nov 13 2025

Dry conditions and seasonable temperatures were seen today, with
temperatures rebounding nicely into the upper 50s and low 60s by
1pm for most locations. Mid and high level clouds this morning
kept northeast IA and northwest IL a little cooler today slowing
its warmup. Surface observations and RAP analysis show high
pressure centered over southern IL with return flow developing
over the local area.

Late Afternoon-Tonight...clouds will continue to diminish as surface
high slides east into the Ohio river valley. A weak warm front will
lift northeast into eastern IA overnight, which will keep low
temperatures warmer than previous days only dropping into the upper
30s to mid 40s. In addition, the latest RAP13 17z run suggest some
low clouds may develop over central MO and move into southeast IA
and west central IL late tonight keeping temps warmer.

Friday...continued dry conditions with well above normal
temperatures closer to what we see in late September is forecast!
Southerly flow and WAA characterized by anomalous 850mb temps rising
to 15-16C (which is near the daily max for Nov 14th per SPC
sounding climatology) will boost temps into the upper 60s and
lower 70s. If we mix just a little deeper than forecast, than
we may be even warmer tomorrow like what the raw GFS and CMC
models show. Our current forecast is within 3-5 degrees of
record highs for the Nov 14th (see Climate section below).
Another interesting note is that if our 00z sounding tomorrow
evening records a 15.3C 850mb temp or warmer, it will be a Top
20 warmest soundings for the month of November at that level.
Friday night will be mild with continued WAA in the warm sector
ahead of the cold front. Lows will only drop into the 50s for
most, which is close to normal highs for the date!

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Issued at 204 PM CST Thu Nov 13 2025

Saturday...after a mild start, a cold front will move through
in the morning with breezy northwest winds developing. Latest
model guidance shows quite the dry sub-cloud layer, with better
forcing and moisture displaced to our northeast in Wisconsin.
Have kept a dry forecast going with only an increase in clouds
and winds behind the fropa. The colder air aloft will be delayed
moving into the region behind the surface front, which will
allow highs to reach the 60s and even some low 70s before temps
begin to drop later in the day in the stronger CAA. Breezy W/NW
winds gusting up to 30 mph will also be seen in the late
morning/early afternoon.

Saturday night-Sunday...large surface high will build into the
Midwest bringing dry and seasonable conditions. Lows in the 30s
and highs in the 50s are forecast with plentiful sunshine.

Early next week will bring our first chance for more widespread
measurable precipitation, as a compact shortwave tracks from
the southwest and moves into the Plains Monday night. Moisture
will be the limiting factor with 850mb theta-e progs keeping
the deeper moisture across MO and southern IL. Still, some rain
is expected with the LREF ensemble 24 hr probability of >.01
precipitation now at 70-90% ending 12z Tuesday. Some of the
solutions depicting a stronger shortwave indicate sufficient
instability to support convective potential, which will bear
some monitoring.

Heading into mid to late next week, forecast uncertainty remains
quite high as there continues to be considerable disagreement in the
mid range deterministic and ensemble guidance with the evolution of
a west coast trough. 00z WPC cluster analysis depicts three
potential scenarios, with one being a more zonal to W/NW flow
pattern aloft and the other two predominantly southwest flow.
The latter two scenarios have the most EPS members and would be
notably warmer, and potentially wetter with convective
potential. Meanwhile, the zonal to W/NW flow has support from
more of the GEFS and CMCE members and would be much cooler and
bring a more southerly track of the energy opening up the
potential for rain and snow. Suffice to say this has big
implications to the temperature forecast as well, as indicated
by the differences in NBM interquartile ranges (25-75th) for
highs which are quite sizable at 12-17+ degrees for Tuesday and
9-15 degrees Wednesday. Deterministic NBM is around climo
during this time and seemingly reasonable given the amount of
uncertainty. Needless to say, be prepared for some volatility
and changes in the coming days to the forecast heading through
next week. Stay tuned!

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1103 AM CST Thu Nov 13 2025

VFR conditions are expected through the period, with high clouds
gradually decreasing this afternoon and evening. There remains a low
chance (10-20%) of MVFR fog and/or low clouds at CID/DBQ/BRL
overnight in the vicinity of a warm front around 12z. Decided to
leave out mention due to the continued low probabilities. Light
south winds will be seen throughout much of TAF cycle.
