What happened

The episode as NWS PAH wrote it up.

In the wake of the departing Presidents Day winter storm, Arctic air surged south on gusty north winds. Dangerously low wind chills were observed during the early and mid morning hours. Gusty north winds were accompanied by actual temperatures around zero degrees, including a low of 2 below zero at Carbondale. Wind chills dropped as low as minus 10 to minus 15 degrees over much of southern Illinois. This Arctic outbreak was part of a longer duration cold snap that descended into the region on February 7 and didn't let up until the afternoon on February 20. The duration of this cold air outbreak was impressive for the lower Ohio Valley. Carbondale, IL tied an all-time record with 13 consecutive days remaining below 32 degrees (set in 1978). Aided by a fresh deep snowpack, overnight lows plummeted below zero in many locations on the mornings of February 16 and 19. Another impressive feat was the duration of dangerously cold wind chills observed February 14-16. In Carbondale, a record-shattering 86 consecutive hours with wind chills below 0 were recorded. The previous record was 22 hours on New Years Day 2018. Wind chill data goes back to 1973 in Carbondale. Carbondale observed an average temperature of 8.0 degrees over a 5-day period from February 13-17. This was the coldest 5 day period since the mid 1990's. Carbondale had four record cold high temperatures and three record low temperatures during the February 13-17 period.

.UPDATE...
Issued at 1153 PM CST Mon Feb 15 2021

The AVIATION section has been updated for the 06Z TAF issuance.

UPDATE Issued at 955 PM CST Mon Feb 15 2021

With the significant accumulating snow finally diminishing over
the Tri State, we have cancelled the Winter Storm Warning. Some
areas of very light snow and blowing snow may continue for much of
the night, but additional accumulations are not expected. Wind
chills will likely be near Advisory levels over portions of
southeast Missouri and southwest Illinois, but we have decided to
handle that and the continued travel difficulties in a Special
Weather Statement. This will effectively wipe the slate clean for
the midnight shift so that they can focus on the
Wednesday/Thursday storm system rather than worry about cleaning
up after this one.

Can't wait for our late bout of winter to come to an end.

.SHORT TERM...(Tonight through Tomorrow)
Issued at 248 PM CST Mon Feb 15 2021

Short wave currently rotating ne through nern AR will likely help
to bring deformation area of a final heavier bust of snow late
this afternoon to areas of western KY into far sw IN, where drier
surge currently resides. Could be a back-end loading of snowfall
to what has amounted to a frustrating winter storm for that part
of our region. In addition to the dry slotting, and extended
period of snow grains/graupel during the first hours of the event
served to cut overall snow totals over portions of wrn KY.

Thinking we could see another 2-4" late this afternoon into early
evening before precip tapers and ends. Expecting to wind up with
overall totals 5-12" across the area...with lowest end over the
southern Pennyrile of wrn KY, with higher amounts the farther
north and west one goes.

Should be in between systems late tonight and Tuesday. However,
the very cold conditions will continue. Though northwest winds
will taper some during the overnight, temps by sunrise are
expected to dip to near zero portions of se and sw IL...with upper
single digits far east where winds will take longer to subside.
With the fresh snow cover Tuesday and a lack of sunshine at many
locations, will be tough to get readings much higher that the
lower/mid teens.

.LONG TERM...(Tuesday night through Monday)
Issued at 248 PM CST Mon Feb 15 2021

Another round of winter weather is expected during the Tuesday night
through Thursday time period. Cleanup will still be ongoing from
today's storm, since Arctic temperatures will hamper snow and ice
removal. Impacts will be high, even if snowfall amounts do not reach
warning criteria.

Considering how close the event is becoming, there is an unusually
wide range of model solutions. The model 500 mb height fields vary
across the central states. The ecmwf ensemble mean continues to
depict a positively-tilted, sheared 500 mb trough. The weaker
dynamics result in less qpf, under one-half inch liquid equivalent
across the region. The gfs ensemble mean depicts a somewhat sharper
and more neutral tilt to the trough, with much higher qpf,
especially south of the Ohio River.

Based on collaboration with WPC, the forecast will lean slightly
toward the gfs. While it is too soon to specify snowfall amounts,
the potential for 4 or more inches is high south of the Ohio River
and parts of se Missouri. Models indicate the 850 mb zero isotherm
will again be nosing up to the Pennyrile of west Kentucky, so sleet
or snow pellets will likely reduce snow-to-liquid ratios there.
Across the north, due to a sharp gradient of forecast qpf, the
potential is low to moderate for heavy snow north of the Ohio River.

Most of the qpf will fall late Wednesday through Thursday. Although
some light snow is forecast Tuesday night into Wednesday morning,
this precip will not be directly associated with the primary
shortwave. This allows more time to assess precip potential before
any headlines are issued.

The other story will be very cold temperatures, which will continue
to hamper snow and ice removal. Lows will be from 5 to 15 Thursday
night, with wind chills near zero.

Friday will finally bring a return to dry weather after a long week
of wintry weather. Friday holds onto northwesterly flow, with a
slight southward resurgence in the trough behind the Thursday
system, so temperatures will remain cold with highs in the 20s.
Single digit lows will be possible in Southeast Missouri and
Southern Illinois, so once again sub-zero wind chills Friday morning
are possible for those areas. With high pressure moving over the
Appalachians for the weekend, along with low pressure in the
Northern Plains, a turn towards southerly flow across the Quad State
may have Saturday finally make it to above freezing. While Sunday
and Monday are currently forecast to reach the 40s, this could end
up a decent amount cooler if snow cover remains across the Quad
State. The Northern Plains low pressure center is forecast to move
through to our north Sunday-Monday. Light rain would be the primary
precip type with some mixing of snow possible Sunday night.
Ensembles are in reasonable agreement on this system for something 7
days out, with differences more a timing matter, though the Canadian
ensemble is a little wetter than the GFS/ECMWF.

.AVIATION...
Issued at 1153 PM CST Mon Feb 15 2021

MVFR ceilings are re-developing across the region and they may
persist through the entire forecast period. There are also areas
of MVFR snow and flurries which could linger as well. Northwest
winds around 10kts will slowly diminish tonight and Tuesday and
light winds will prevail for the evening hours.

of wintry precipitation to all or portions of our region. The
primary precipitation type appears to be snow for much of our
region. A wintry mix of sleet and snow is more likely in parts of
western Kentucky.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated, but storm total snow
reports are encouraged.

...Dangerous Driving Conditions and Bitter Cold Tonight...

The accumulating snow has ended across the Quad State region, but
roads throughout the region will remain slick and hazardous
through the Tuesday morning commute. In addition, wind chill
temperatures by sunrise will range from zero to 10 below, and
portions of southeast Missouri and southwest Illinois may be even
colder.

The bottom line is that travel is strongly discouraged tonight
and Tuesday morning. If you must travel, check road conditions
and keep an emergency kit in your car. Take it slow and avoid
sudden braking. If you must be outside dress in layers and try to
limit your exposure as much as possible.
