What happened

The episode as NWS PAH wrote it up.

A moist 500 mb shortwave trough tracked east from the Plains, causing a surface low pressure center to develop northeast from Texas to the central Appalachians. Widespread wintry precipitation occurred as colder air filtered south on the back side of the low. Around one-tenth of an inch of ice glazed surfaces across southern Illinois. Near the onset of precipitation, a period of sleet was reported. Most of the precipitation fell in the form of freezing rain. The automated observing station at the Carbondale airport measured 0.11 inch of ice accretion. Most of the icing was on trees, power lines, and elevated surfaces during the precipitation. After the precipitation ended, temperatures fell through the 20's, causing icy spots to develop even on paved surfaces. Slick roads and motor vehicle accidents were common during the early morning hours. Several wrecks occurred on Interstate 57. In Union County, a tractor-trailer rig crashed and caught fire on Interstate 57. In Franklin County, a Greyhound bus crashed into a trailer being pulled by a sport utility vehicle.

.SHORT TERM...(Tonight through Thursday night)
Issued at 258 PM CST Tue Feb 6 2018

The main concern for tonight continues to be winter hazards. A
variety of winter precipitation types is expected. A moist 500 mb
shortwave will track east from the Plains tonight. Widespread
precipitation is developing across Arkansas and Tennessee this
afternoon. This precipitation will spread northeast across our
region this evening. A pronounced elevated warm layer will keep
snow to a minimum, although some minor accumulations around an
inch are expected in parts of southern IL and southwest IN.

The primary precip type is still expected to be freezing rain in
areas south of a kmdh to kevv line. The 12z model runs generally
trended higher with qpf in western KY and parts of se Missouri.
This higher qpf overlaps the sub-freezing air in parts of se
Missouri. Therefore, icing amounts have been increased to around
one-quarter inch there. An upgrade to an Ice Storm Warning has
been issued for several counties, mainly in se Missouri.

The freezing line will be critical in this event. It appears the
freezing line will remain fairly close to the Ohio River and the
Missouri Bootheel early tonight. A slow southeast movement of the
freezing line is expected late tonight, which should result in a
change to freezing rain in much of western KY. The southern
Pennyrile region will be the last to change over. A Winter Wx
Advisory may be required there for the early morning hours of
Wednesday, depending on how quickly the precip moves out.

Rainfall amounts in the southern Pennyrile including khop will be
over an inch within a 12-hour timeframe. This may cause some
localized drainage issues. A Special Wx Statement will be issued
for that area for the heavy rainfall, followed by the potential
of icy spots early Wednesday.

The precip will end early Wed morning across most of our region.
North winds will increase to around 15 mph by early Wed morning.
This could pose a problem for ice-laden trees, mainly in areas
that receive 0.25 inch or more of ice.

Skies are expected to clear out on Wednesday. The sunshine should
boost temps to around or just above freezing in the
afternoon, and winds will diminish gradually after noon. Temps
will quickly drop after dark, with lows in the teens Wed night.

.LONG TERM...(Friday through Tuesday)
Issued at 258 PM CST Tue Feb 6 2018

High pressure to our east will keep our region dry for the end of
the work week.  South winds around the high will bring moisture
north, along with warmer conditions.  Models show a cold front
sinking south Friday night, colliding with the moisture coming up
from the south.  Precipitation will move into southern portions of
the PAH forecast area late Friday night, spreading north across the
entire area Saturday morning.  Precipitation will start as snow or a
rain/snow mix, gradually becoming all rain from southeast to
northwest Saturday morning as temperatures warm into the 40s. Areas
of low pressure will move along the front, and rain will continue
through Saturday afternoon, changing back over to snow from
northwest to southeast Saturday night.  Low chances will continue on
Sunday, and with north winds bringing colder air into the region,
any precipitation in northern portions of the area may just stay a
rain/snow mix through the day.

High pressure will move over our region for Sunday night into
Monday, giving us dry and near seasonal conditions.  Models show an
area of low pressure over the Great Lakes region Monday night, and
GFS shows a trailing cold front giving us precipitation chances late
Monday night into Tuesday. Kept possibilities in the chance category
due to the ECMWF pretty much keeping the front farther west during
that time frame. With colder air in place, any precipitation would
be snow or a rain/snow mix late Monday night into Tuesday morning.

.AVIATION...
Issued at 501 PM CST Tue Feb 6 2018

Not many changes with previous TAF's. We go MVFR overnight with
freezing or frozen precip for all sites. Also extended the cigs
and precip a few hours longer until we approach sunrise. By
sunrise we should be out of the precip with VFR cigs. We will
likely get rid of cigs after 18z wed.
