...A Major Winter Storm is expected late Tuesday into Thursday...
Attention was given almost exclusively to the mid-week winter
storm. The forecast remains on track for the major winter storm
that will impact the forecast area starting Tuesday night and
continuing through Thursday.
Key Messages:
1. Event Occurrence: Confidence remains high that a significant
winter storm moving through the forecast area beginning Tuesday
night and lasting into Thursday.
2. Impacts: Significant accumulations greater than 6" of wet, heavy
snow is expected across a large portion of the forecast area,
falling mainly between Wednesday and Thursday. A corridor of greater
than 12" of snow and significantly less wintry mix is possible along
and north of the I-70 corridor where forcing will be greatest. Ice
accretion in excess of 0.10" is expected across southeastern
Missouri and southern Illinois, and combined with breezy conditions
during and after the event could result in power outages.
3. P-Type: Uncertainty remains in the exact transition of rain to
wintry mix to snow and the timing of these transitions. There is a
chance that some areas around the I-44 corridor and associated areas
eastward could see significantly more sleet than snow.
4. Longevity/Timing: The system is still expected to exit the region
during the day Thursday, though light snow could linger in its wake,
particularly east of the Mississippi River.
5. What's Changed: Guidance has come into better agreement on the
track and movement of the low, and is consistently placing the
corridor of heaviest snowfall along and north of the I-70 corridor.
6. Remaining Uncertainty: As in previous forecasts, the depth and
speed of the cold air aloft into the region remains uncertain and
will have significant impacts on how much ice, sleet, and snow
accumulations over much of the forecast area.
Forecast details:
The northern stream axis of a split stream trough will move
across the US-Canada border during the day Tuesday with a surface
low sliding from the Great Lakes region into New England. The low
will drag a robust cold front southward into the forecast area
Tuesday afternoon. Rain will bloom ahead of and along the front,
aided by warm air advection along southerly flow, as it moves
through the moist and seasonally warm air across the region.
Temperatures will be seasonally warm ahead of the front thanks to
the increased warm air advection.
By Tuesday night the entire split stream trough will be moving
through the western half of the CONUS, keeping the region within
southwesterly flow aloft and positioning the area between the
upper- level jet couplet. At the surface the cold front will be
stalled just south of our forecast area. We will have no shortage
of lift for precipitation with mid-level disturbances traveling
northeast across the region, interaction with the ULJ dynamics,
and isentropic lift and warm air advection overrunning the front.
Overnight Tuesday into Wednesday cold air will continue surging
into the region behind the cold front and beginning to erode the
elevated warm nose. Confidence is high this transition will occur
quickly Tuesday evening across northeast Missouri and portions of
far west-central Illinois closest to the Iowa-Missouri border.
Confidence decreases across areas further south where guidance
sources continue to diverge in how rapidly the profile will cool.
As it stands a period of wintry mix, including sleet and freezing
rain, is expected overnight across central and east-central
Missouri and portions of west-central Illinois before
transitioning to mostly snow.
Precipitation will fall across the bi-state region through the day
Wednesday, though we could see a brief break in precipitation or at
least lighter QPF Wednesday afternoon and evening at the entrance
region of the ULJ moves northeast of the forecast area and
isentropic lift decreases. Precipitation type during this period
continues to be uncertain due to thermal profile so I can't rule out
sleet and freezing rain mixing into the snow along and south of I-70
during the morning Wednesday. Southeastern Missouri and southern
Illinois will be last to cool and so last to make the transition
from liquid rain to frozen precipitation Wednesday afternoon. The
elevated baroclinic zone is then expected to stall through this
region, and combined with chilly surface temperatures, is expected
to produce ice accumulations over a 1/4" across the far
southeastern CWA. These values could still change as guidance gets
a handle on the thermal profile. There is a reasonable chance
that if elevated temperatures do not cool enough in the
transitional area along and around the I-70/I-44 corridor that
much of the current forecast snow falls as sleet.
By Wednesday night the southern stream of the mid-level split stream
moves into the region. A low will move northeast through the lower-
Mississippi Valley during this period in concert with the approach
of the mid-level trough. Forcing from the low will provide robust
lift for precipitation across the forecast area, and given the
classic Midwest heavy snowfall model, a narrow corridor of heavy
snowfall is expected on Thursday. The current track of the low
places the heaviest snowfall through areas along and north of I-70
in Missouri and Illinois. Precipitation is expected to be
predominately snow from Wednesday night through the end of the storm
given the more robust push of cold air into the region on the
northwest side of the low. By Thursday afternoon the low will track
east-northeastward out of the region in concert with the
northeastward lifting trough, aided by a robust high moving into the
area. Winds will be breezy overnight Wednesday into Thursday, and
while blowing snow is no longer considered a threat, power outages
associated with these winds and significant ice accretion on the
powerlines is possible.
This a long duration winter event with heavy, wet snow forecast to
fall across the area for 36-48 hours. Settling of the snowpack
should be expected over the event, which will impact storm total
snow amounts and could create a discrepancy between the current
forecast and final totals.

.LONG TERM... (Friday through Next Monday) Issued at 307 PM CST
Mon Jan 31 2022
The long term forecast calls for a much needed break from impactful
weather after this week's upcoming winter storm. Friday will be
similar to Thursday in terms of temperature. Lighter winds than
Thursday can be expected as well as surface high pressure moves
deeper into the area. Wind chills will still feel unpleasant, with
most of the area falling in the 10 to 20 degree range.
A cut-off low pressure system during this time will be developing
over and traversing the desert southwest at 500 mb. By Saturday,
this feature will be in the Central Plains. It will serve to turn
upper level winds to the southwest in our CWA. Meanwhile, at 850 mb,
the ridge settled over the Midwest will scoot eastward, leaving our
CWA in southwest flow in the lower levels as well. This, along with
an increase in insolation, will help boost temperatures into the
upper 20s to upper 30s Saturday. Temperatures will continue to climb
from there. By Sunday, we should be flirting with normal values
again.
An upper level shortwave will dive south from the Canadian Rockies
Saturday and Sunday. Its attendant low pressure system will threaten
to drive a cold front through our area sometime Sunday into Monday.
Although a majority of ensemble members are dry, there is still the
possibility of precipitation associated with this frontal passage.
Discrepancies appear in deterministic guidance regarding the path,
timing, and strength of the surface low as well. The GFS and
Canadian swing the low in and out of the area much faster than the
Euro. With it still being a week away, all we can do is keep
monitoring this feature.

.AVIATION... (For the 06z TAFs through 06z Tuesday Night)
Issued at 1042 PM CST Mon Jan 31 2022
VFR conditions will persist in the beginning of the period with
scattered/broken high clouds streaming overhead. A strengthening
low level jet will also increase the potential for low level wind
shear, including directional and speed shear.
The greatest impacts are expected late Tuesday night into
Wednesday. Rain will develop through the day Tuesday. Colder air
will transition rain to a brief wintry mix at KUIN late Tuesday
afternoon, then quickly to snow Tuesday evening. This trend will
progress southeast through the overnight hours with the transition
impacting KCOU/KJEF around midnight Tuesday night. The changeover
will likely hold off until around 08z or 09z Wednesday morning
for metro terminals, just beyond the valid period.
MVFR cigs are going to accompany rainfall, followed by a gradual
lowering to IFR Tuesday night. Visibility restrictions will be
marginal with rainfall, but will be quickly reduced with the
changeover and commencement of snowfall. Should IFR ceilings not
arrive by the end of the effective period, IFR is expected to
shroud much of the area by Wednesday morning. Lower visibilities
will likely accompany snowfall after transition. 1-3SM
restrictions will likely become common at KUIN/KCOU just beyond
the end of the period.
SPECIFICS FOR KSTL:
VFR will continue for the next several hours with high clouds
streaming overhead. Low level wind shear potential will exist
through mid-morning, both due to directional and speed shear.
A high impact event is likely across the region from late Tuesday
into Wednesday. This will start off with rainfall Tuesday
afternoon into Tuesday evening, preceding colder air that will
arrive after midnight. A cold front will approach the terminal
from the northwest between 08z and 10z Wednesday morning, as MVFR
ceilings slowly give way to IFR ceilings. How fast the cold air
arrives will be the deciding factor on the potential for IFR/LIFR
conditions heading into Wednesday morning. Rain is expected to
transition to a mix of freezing rain, sleet and snow. Once winter
weather begins, probabilities for visibility restrictions will
increase rapidly with 1-3SM restriction likely.
Though it is just beyond the effective period, Wednesday will
introduce widespread, high impact winter conditions. This will
continue to be better detailed in subsequent updates.
