Area Forecast Discussion...Updated Aviation
National Weather Service Lincoln IL
1111 PM CST Sat Jan 24 2026

.KEY MESSAGES...

- A long-duration winter storm has begun, with impacts likely to
  ramp up overnight into Sunday. A northward shift in guidance
  resulted in a slight uptick in forecast snow totals, with most
  areas in the Winter Storm Warning expected to see 6-11 inches of
  snow. The highest snow amounts are still expected south of I-70.
  Snow amounts will decrease to the northwest, with 1-4" of snow
  northwest of the IL River.

- Northerly winds gusting to around 25 mph on Sunday could lead to
  blowing and drifting snow, especially on east-west oriented
  roads.

- Wind chills will be 'warmer' tonight, between 0 and 10 degrees
  below zero. Colder conditions return Sunday night into Monday,
  with wind chills of 15 below likely (60-80% chance). A Cold
  Weather Advisory has been issued for Sunday night through midday
  Monday.

&&

.UPDATE...
Issued at 922 PM CST Sat Jan 24 2026

Last couple of hours, radar has been showing an enhanced band of
snow over northwest parts of our CWA...in Knox county. Some HiRes
models did show a fgen band over the area with slightly higher
snowfall amounts. Guidance does suggest this will continue for
several more hours tonight. Believe snowfall amounts and impacts
warrant including Knox and Stark counties in the Winter Weather
Advisory. So have already updated the grids for that inclusion and
forecast should already be out reflecting that.

.DISCUSSION...
Issued at 240 PM CST Sat Jan 24 2026

*** LONG DURATION WINTER STORM ONGOING ***

A historic winter storm is unfolding across a large swath of the
US through this weekend, with over 180 million people currently
under winter precipitation-related warnings or advisories. A
strong but weakening sfc high pressure remains positioned near the
Great Lakes, resulting in continued northeasterly winds across
central IL. Sfc temps are generally in the single digits above
zero across the ILX CWA this afternoon, and the sfc freezing line
is well to the south (across the far southern Plains/deep south).
The frontal zone then slopes northward with height, with the 850mb
freezing line analyzed from SW TX to near Little Rock, AR, into
TN. An upper low near Baja California is beginning to lift
northeastward, and this will provide better forcing locally as we
proceed into late tonight/Sun. This upper low bring additional
moisture overrunning the frontal zone, not only from the Gulf but
from an atmospheric river over the eastern Pacific.

Light snow has overspread much of the ILX CWA as of 20z/2pm, with
sfc obs reporting visibility between 1 and 2 miles in most
locations. Any accumulations to this point have been minimal. The
HREF continues to suggest that snow rates will remain below a
quarter inch per hour through the daytime hours today.

Much of the expectations regarding the evolution of this system,
including timing of impacts, snow rates, and a NW to SE gradient
in snow totals (with amounts increasing to the SE) remain on
track. The deterministic 12z guidance suite did wobble back
northward. However, we've seen many of these north-south wobbles
over the last several guidance cycles, and would caution against
becoming too caught up on the run-to-run changes of the
deterministic models. Unfortunately, life in the snow gradient
zone means that small changes in the precip placement translate to
noticeable changes to the model snow projections, and the latest
northward shift resulted in a few inch increase to the median snow
amounts across the Winter Storm Warning area.

We still feel that our messaging for this system is on track,
with 5-11" being the most likely outcome for counties in the
Winter Storm Warning, and we still expect a fairly sharp drop off
in snow amounts on the northern side of the system. The latest
probabilistic NBM has a sharp decrease in probability of 6-8" of
snow north of a Jacksonville to Rantoul line, greater than 50-70%
to the south, quickly dropping to just a 20-30% chance in
locations north/west of Lincoln. No changes were made to the
Winter Storm Warning or Winter Weather Advisory with this forecast
package.

To this point, I have not seen any overwhelming signals for
strong mesoscale forcing, such as fgen banding or a cross-hair
signature in the fcst cross sections. The main takeaway here is
that snow rates should stay in check (less than 1" per hour for
much of the event). The potential exception is south of I-70,
where some CAMs (HRRR/NAM Nest) indicate enough QPF during the
06-18z time frame to support snow rates exceeding 1" per hour at
times. This corridor of higher QPF is very close to the
southeastern portion of the ILX CWA, and may wind up staying just
south of our area. This will need to be monitored as additional
models come in.

Much of the discussion/concerns about the microphysics of this
event persist today. To quickly recap, much of the forecast
temperature profile across the Winter Storm Warning area is warmer
than the dendritic growth zone (DGZ), favoring column-shaped
snowflakes that accumulate less efficiently. Further north, where
the temp profile is in the DGZ, the ascent is much weaker and
therefore may also struggle to realize high snow-liquid ratios. If
this event were to underperform expectations, I believe the most
likely culprit would be snow-liquid ratios (SLRs) being lower than
the forecast values of 18:1 or 20:1. Some adjustments were made
this forecast package to start trending the SLRs lower, but the
increase in QPF caused by the northward shift in guidance offset
these changes, and resulted in similar or higher snow totals from
the previous forecast. With this concept in mind, will caution
that deterministic snow maps using the Kuchera ratio appear to be
using 18:1 or greater across a large portion of the ILX CWA for
this event. If our concerns about the SLRs are accurate, these
snow maps will have inflated totals, and that's before
considering other effects like snow compaction.

Northerly winds increase on Sunday, with gusts of 20-25 mph, which
could lead to some blowing/drifting of snow, especially on east-
west roads. Expect moderate travel impacts within the Winter Storm
Warning area through Sunday evening, with a greater than 60%
chance of major travel impacts along and south of I-70. Impacts
become more likely late this evening into Sunday morning.

*** CONTINUED COLD WEATHER ***

The synoptic pattern will continue to feature troughing over the
eastern US and ridging over the western US during the upcoming
work week, which will allow below normal temps to persist. Temps
aren't quite as cold tonight as previous nights. Minimum wind
chill values still won't be pleasant, in the 0 to 10 below range,
but this is warmer than Cold Weather Advisory criteria.

For Sun night into Mon, low temps fall back below zero and wind
speeds increase as a pressure gradient exists between the
departing low and a sfc high over the Plains. There is high
confidence that wind chills drop at least 15 degrees below zero
overnight into Monday morning, so a Cold Weather Advisory was
issued for this period.

As the sfc high shifts southeast of the region and a sfc low
passes by to the north, we see a brief 'warm up' on Tues, with
highs forecast to climb into the 20s. That will be the warmest day
through at least Saturday. One thing to keep an eye on this week
is with a snow cover looking likely, if we get a cool, calm night,
temperatures will likely tank well below the forecast guidance.
For now, both Sunday and Monday night look windy, so did not make
any aggressive temperature edits at this time. Low temps are
forecast to be in the single digits (either above or below zero)
through the week, which is anywhere from 10-20 degrees colder than
normal.

.AVIATION...  (For the 06z TAFs through 06z Sunday Night)
Issued at 1111 PM CST Sat Jan 24 2026

IFR conditions will prevail at all sites due to vis being below
3sm with snow through most of the TAF period. Some vis improvement
to 4sm will be seen at all sites Sunday afternoon. Cigs will be
below 3kft through the TAF period at all sites with below 3kft
during the overnight and morning hours, but then become VFR levels
in the afternoon. Not expecting cigs below 1kft due to northeast
winds, which tend to dry out the lower layers. Winds will be
northeast to start and then become more northerly tomorrow and
tomorrow afternoon. Will also see gusts to just over 20kts
tomorrow and tomorrow afternoon.
