AREA FORECAST DISCUSSION
National Weather Service Charleston WV
523 AM EST Sun Jan 20 2019
.SYNOPSIS...
Much colder and blustery today with snow showers. Remaining cold
through Monday night. Next system mid to late week.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 400 AM Sunday...
Low pressure intensifying as it to the northeast early this
morning, with tightening pressure gradient bringing strong
gusty northwest winds across the forecast area, ushering in
sharply colder air. This ensues a quick freeze of moisture on
roads, to go with a quick change over to snow. A brief period of
sleet and freezing rain across the Ohio river will narrow
further and vanish altogether as it crosses WV.
A few inches ice accumulation over the mountains early this
morning should be about over. The snow showers will amount to an
inch or two this morning across the lowland and southern WV
mountains. Deformation zone lifting through the middle Ohio
Valley got Perry County 5 inches per DOT, with 1 to 3 inch
reports elsewhere in southeast Ohio early this morning.
Snow showers diminish across the lowlands today but upslope
snow persists in the mountains, where 3 to 6 inches could fall
over the most favored higher windward slopes.
Winter weather warning for Perry county continues early this
morning, with winter weather advisories elsewhere.
Meanwhile, the rain brought areas in southeast Ohio and in the
northern WV mountains to minor flooding. Let flood watch expire
as the colder air is ending the threat for new flooding, though
it may take until, dawn to shut off the runoff west, a little
later this morning east.
Snow showers diminish to flurries in the mountains tonight, as
stratocu breaks across the lowlands in the arctic air.
After the sharp drop early this morning, temperatures steady or
falling slowly today. Lowered lows tonight into the single
digits, single digits below zero over the higher terrain, where
a wind chill warning will be needed, wrapped with a wind chill
advisory over some of the lower northern and central mountains.
Also, wind advisory remains in effect over the higher ridges,
with gusts to around 40 kts today. Gusts to 30 kts elsewhere,
mainly early this morning and in southeast Ohio along with
surrounding lower mountains terrain and other more exposed hill
and ridge tops.
&&
.SHORT TERM /MONDAY THROUGH TUESDAY/...
As of 230 AM Sunday...
Other than some lingering snow showers in the northern
mountainous counties of WV to start the period, expecting a dry
short term as high pressure at the surface continues the cold
weather. The high will cross Monday night, allowing ideal
radiational cooling. Opted to undercut the consensus blend lows
by a significant amount...especially across the northern
mountains. Temperatures at 850mb are still in the -15C to -25C
range, which should provide sub zero lows across much of the
northern mountains of WV. The coldest guidance I could find is
the ECMWF mos, followed by the NAM mos. So used a blend of these
two products for lows Monday night.
Temperatures do begin to warm nicely on the back side of the
high for Tuesday. Clouds will also be on the increase ahead of
the next system, but held off on any precip making it in prior
to 00Z Wednesday.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
As of 230 AM Sunday...
Models are in a bit better agreement through the long term than
they were 24 hours ago, but still some differences in timing
as multiple system move through keeping us in an unsettled
pattern.
The first will be a cold front that crosses Wednesday and
Wednesday night. Have some brief wintry mix as the precip moves
in ahead of the front Tuesday night. But WAA should keep this
mainly rain. The best chance for wintry precip will be the
eastern slopes where a period of freezing rain is
possible...mainly depended on timing and precip and eroding the
cold air.
Following this front, cold air surges back in with a quick
transition to snow Wednesday night into Thursday. We should have
a 500mb shortwave trough crossing at this time as well, so could
get a quick burst of snow before the better moisture moves out.
Confidence is lower through the remainder of the long term as
several upper troughs move through so stuck close to the
consensus blend for now. Temperatures do remain cold enough for
most precipitation to fall as snow. Friday into Saturday looks
like another bitter cold period.
&&
.AVIATION /09Z SUNDAY THROUGH THURSDAY/...
As of 125 AM Sunday...
A potent, moisture laden low pressure center crossing the area
overnight, with a tightening temperature gradient, will bring a
sequence of quick weather changes, as it tracks from about
Williamson to Charleston to Elkins through 09Z, and then off to
the northeast.
Gusty northwest winds had already commenced along the Ohio
River, with IFR ceilings and variable visibility in rain that is
likely to change briefly to freezing rain and then sleet,
before changing to snow by 08Z. Farther east, CRW, CKB and EKN
were having VFR conditions, although bands of showers could
bring MVFR to IFR visibility at times overnight. Also, IFR
stratus at BKW may come and go overnight.
The transition to snow will take much of the overnight to
progress farther east, but will finally do so very quickly 11Z-
12Z. A brief period of IFR in blowing snow is likely 09Z-13Z
along the Ohio River, and 12Z-15Z CRW and CKB, EKN and BKW.
As the system moves quickly east Sunday, visibility will
improve to VFR HTS, PKB and CRW by mid morning Sunday, and CKB
early Sunday afternoon, although MVFR stratocu may persist much
of the day. The mountain sites EKN and BKW are likely to have
IFR ceilings through Sunday morning with IFR visibility at times
in snow showers, improving to IFR Sunday afternoon, but with IFR
in snow showers still possible.
Conditions will improve further Sunday night, with holes in the
MVFR stratocu amid lingering flurries.
The gusty northwest surface flow along the Ohio River will
commence at sites farther east, as the low goes by 10Z-12Z
Sunday. These strong, gusty winds will continue through the TAF
period, except diminishing a bit along the Ohio River Sunday
night. Strong south to southwest flow aloft overnight will
switch to moderate north to northwest first thing Sunday
morning, and then remain so through Sunday night.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z MONDAY...
FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Timing of quickly changing conditions is
likely to vary overnight into Sunday morning. Snow showers may
bring brief IFR conditions through Sunday afternoon, mainly
east of the Ohio River. This will depend upon where the
scattered snow showers form and drift to, and even where plumes
may set up off the Great Lakes.
