Area Forecast Discussion
National Weather Service Blacksburg VA
103 PM EST Thu Nov 15 2018
.SYNOPSIS...
A deepening low was off the southeast coast with a high over New York
wedges down the Appalachians. By Friday morning the low will be
close to Long Island. High pressure will be over the Mid Atlantic
region Saturday, followed by a cold front that will sweep out of the
Ohio Valley on Sunday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
As of 1000 AM EST Thursday...
Upper level closed low will drift northeast into the Ohio
Valley this afternoon. Meanwhile, the parent ridge of the wedge
will remain over New England. The good news is that the wedge
will erode over the area, allowing temperatures to recover above
freezing heading into this afternoon. Most areas are reporting
freezing rain with temperatures right around 32F, give or take a
degree. Rainfall rates have also increased as the back edge of
the precipitation begins to enter the area from the south at 10
AM. Given temperatures are warming and rainfall rates have
increase, any addition ice accretions will be minor. Winds have
not been an issue, except over the piedmont where cross-barrier
jet resides. However, icing has not been as great compared to
the mountains. Winds are expected to increase some over the
mountains as precipitation departs, but ice should melt by
then. We will start canceling winter weather headlines as
precipitation exits and temperatures warm.
At this time, flooding has not been an issue as most of the
precipitation has been frozen, keeping runoff slow. Storm total
rainfall amounts over the Dan River basin have ranged from an
inch to an inch and a quarter. Another quarter to half of
an inch is expected into early this afternoon. There still
exist the threat for road closures due to high water, therefore
will keep current flood watch as is. New river forecasts for the
Dan River will be issued by 11 AM.
As of 305 AM EST Thursday...
No changes planned to any headlines at this time.
Classic mid-latitude cyclone early this morning over the eastern
United States. Warm conveyor belt progresses east today as the upper
low tracks across Kentucky and West Virginia. Dry slot reaches
western Virginia in the afternoon. Latest RAP was trending a bit
slower with the back edge of the main shield of precipitation,
reaching Lynchburg and Danville around 5PM.
Coldest air aloft and deepest moisture with the upper low moves
across southeast West Virginia and the Alleghany Highlands
overnight. At the surface, low pressure off the Georgia coast will
continue to deepen as it moves northeast toward the DelMarVa region
by this evening. Once the low reaches a far enough north latitude
winds will torn to the northwest. A 35 to 45 knot 850MB jet will
result in enhanced upslope on the western side of the central
Appalachians and downslope clearing east of the Blue Ridge. Will
make subtle adjustments to the timing of the precipitation today and
will veer the forecast wind more to the northwest tonight.
Watching the dew point depression gradually shrink from southwest to
northeast as the air mass saturates. 06Z/1AM special sounding from
KIAD still showed some dry air and room for evaporative cooling
below 650MB. Also seeing that reflected in the surface obs in
Rockbridge and Botetourt Counties with an 8 degree dew point
depression. As of 2AM getting some reports of icing and below
freezing temperatures along the spine of the Blue Ridge, in
southeast West Virginia, in northwest North Carolina, and in the New
River Valley. Will be using a non-diurnal trend to reflect
additional cooling for temperatures today.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
As of 305 AM EST Thursday...
As the low pressure system departs, conditions will be blustery and
cold across the Appalachians and central mid Atlantic region with
lingering snow showers west of the Blue Ridge dissipating by the
afternoon. The upper pattern will then become zonal with fair weather
expected through the weekend. One potential fly in the ointment is a
plume of low level moisture that may move down from the northwest and
bring more clouds to locations west of the Blue Ridge Friday night into
Saturday. However the correlation between upstream satellite imagery
and guidance RH fields is not stellar so confidence in the added cloud
cover is not high so will maintain the fair weather forecast for now. A
weak front will approach from the northwest with a chance of rain/snow
showers west of the Ridge late Sunday night.
Temperatures are expected to remain below normal through the weekend.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 300 PM EST Wednesday...
A weak front may bring some rain/snow showers to locations west of the
Blue Ridge through Monday morning. However, then pattern aloft shows
more of a fast zonal but northwest flow and this will keep us in drier
pattern for now, with temperatures still averaging 5 to 10 degrees
below normal, especially high temps.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
As of 1240 AM EST Thursday...
Rain beginning to pull out of the area early this afternoon, but
low clouds and possible drizzle to hang around through the
afternoon. Good news is that temperatures will warm above
freezing through the afternoon.
MVFR to IFR ceilings will hang around into the evening along and
east of the Blue Ridge. A closed low will drift to the Ohio
Valley and increase mixing over the region. As winds increase
from the west, low clouds will dissipate along and east of the
Blue Ridge. For the west, ceilings and visibilities will become
VFR by mid afternoon, then lower to MVFR as showers from the
closed low advance towards the area. Rain showers will change
over to snow through the evening. Snow showers will be more
intense along western slopes between 02Z-10Z Friday. Through the
morning hours snow showers will taper off from south to north
with everyone returning to VFR.
Modest pressure rises and an increasing NW cross barrier jet
will bring breezy conditions to the area starting across the
mountains after midnight then the entire region during the day.
Northwest winds gusting to 25KTS will be common with gusts to
45KTS along ridgetops.
Confidence is average for timing of the precipitation,
precipitation type, and ceilings, and above average for all
other elements.
Extended Discussion...
VFR conditions with a mostly clear sky will return across the
region for the weekend. Models suggest a chance for MVFR
ceilings in southeast West Virginia on Friday night and Saturday
morning but confidence is this occurring is low.
&&
.HYDROLOGY...
As of 305 AM EST Thursday...
Will be basing rainfall amounts for the rest of the event heavily
off of the Weather Prediction Center forecast numbers. This amount
of rainfall over the Dan River basin will likely bring Danville back
into flood. Additional evaluation and modification of forecast river
levels will be made again later this morning. Strongest isentropic
lift and best advection of higher precipitable water, up to 1.5
inches, will be through 1PM.
