Area forecast discussion, Apr 19, 2:53 PM EDT, 40 minutes before
Area Forecast Discussion
National Weather Service Blacksburg VA
253 PM EDT Thu Apr 19 2018
.SYNOPSIS...
Low pressure over Virginia will move offshore and up the
northeast coast today with a cold front advancing from Virginia
to Florida by this evening. A large high builds in behind this
system and will cover the eastern United States Friday and
Saturday. A low pressure system over the Southern Plains
Saturday will move east, reaching Georgia by Tuesday.
&&
.NEAR TERM /THROUGH FRIDAY/...
As of 935 AM EDT Thursday...
Upstream radars show precipitation associated with short wave
energy rotating around the base of the upper trof heading in our
direction, and this is captured well in POP grids.
Winds this morning are underperforming a bit compared to
conditions advertised in yesterdays guidance. 06Z NAM low level
winds seem to match 12Z RNK sounding best and Bufkit indicates
that once better diurnal mixing kicks in it will still be a
blustery day. No changes planned for current wind advisory but
it looks like it will be closer to the low end of criteria. As
winds pick up and drier air moves in, ground fuels will dry and
create enhanced fire danger east of the Blue Ridge through
early this evening.
Previous discussion...
Combination of pressure rises, low level jet and cold air
advection will be enough for gusts of 40 to 50 mph at the
highest elevations. Have lowered minimum temperatures a couple
of degrees for tonight which brings lows to near freezing north
of Lynchburg. Will introduce Freeze Watch for tonight from
Appomattox County to Rockbridge County. Winds lighten but
questionable if they get light enough to allow for frost across
southern Virginia and northern North Carolina, given that the
center of the high will be over the western Great Lakes.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 230 AM EDT Thursday...
High pressure will rule the roost into the weekend with no rain
expected until early next week. Cloud cover will increase each day,
as well as afternoon temperatures. Friday's highs will range from
the 50s west of the Blue Ridge to the low to mid 60s east.
Widespread 60 degree temperatures are expected Saturday with the
exception of higher ridges being in the mid 50s. More 60 degree
temperatures on tap Sunday with the piedmont flirting with the lower
70s. Temperatures Sunday are close to normal highs for this time of
year.
Temperatures Friday night going into Saturday morning will range in
the low to mid 30s. Low level moisture will be scarce, but some
patchy frost is possible. Sensitive vegetation should be protected.
Temperatures Saturday night into Sunday morning will be mild with
temperatures ranging from the mid to upper 30s west and lower 40s
east.
&&
.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
As of 145 PM EDT Wednesday...
Going to be wet/cool but not cold period, as upper low develops over
the lower MS Valley Sunday and pushes across the northern tier of
the Gulf Coast states Sunday afternoon into Tuesday. Models have
trended north, but would like to see more consistency in them, as a
further south track would lead to dry/cool with more sun while north
would be wetter/cloudier but still a bit on the cool side.
For consensus, models are showing more of cloudy pattern with threat
of rain each day. As the low moves off the coast Wednesday, a
northern stream front shift in from the northwest with another
threat of showers.
Sunday appears the drier of this period with increasing clouds.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
As of 250 PM EDT Thursday...
Gusty winds will gradually be subsiding at TAF sites overnight
as high pressure builds over the region. Locations east of the
Blue Ridge will generally have VFR conditions throughout the
period, but locations west of the Ridge will start off with MVFR
cigs and some rain/snow showers in the vicinity, before
trending to VFR early this evening.
Extended Aviation Discussion...
VFR conditions into Saturday as high pressure slowly builds in
from the northwest. Winds will continue to diminish into
Saturday.
Clouds will begin to creep back into the area on Sunday in
advance of an approaching low in the Lower Mississippi River
Valley. However, cigs should remain VFR even while the ceiling
heights lower and clouds thicken. SCT MVFR showers are possible
in southern Virginia and northern North Carolina Sunday night
with rain becoming more widespread across the Mid Atlantic
region on Monday.
