.NEAR TERM /THROUGH WEDNESDAY/...
As of 930 PM EDT Tuesday...
Key Message:
1. Showers of rain will be possible this evening, continuing
into Wednesday morning.
Showers continue this evening, though concentrated north of
Interstate 64. On the whole, amounts have been light and there
has been no convective activity, as expected. Forecast has been
reliable, and as such, no major changes have been made with the
evening update.
From the previous discussion...
Mostly cloudy skies have overspread the region as a cold front
continues to shift east through the Midwest. Showers associated
with the front are already beginning to move into southwest
Virginia and southeast West Virginia. However rain activity
will remain spotty through the remainder of this afternoon and
evening with perhaps a slight uptick overnight. Trends in model
guidance have been showing the bulk of the rainfall moving
north and west of the area coinciding with the better forcing
associated with the upper tough. In response to this, have
lowered storm total rainfall amounts a little, as well as PoPs
through this evening. Very low confidence of any thunderstorms
with little to no instability. Opted to not add mention of
thunder.
Cold front will be in the process of crossing the area Wednesday
morning and should be situated along the coastline will east of
the area by Wednesday evening. Some lingering showers will be
possible through midday Wednesday, but gradual clearing
throughout Wednesday can be expected. High pressure will begin
building in late Wednesday and a notable change in airmasses
will arrive. Temperatures today will be above normal with mild
overnight lows. Warm again Wednesday, especially east of the
mountains, but a sudden drop in dew points by the evening will
have conditions feeling more fall-like.

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
As of 200 PM EDT Tuesday...
Key Messages:
1) Cold front to bring colder and drier air.
2) Frost possible west of the Blue Ridge Friday morning.
A cold front should be fully through the area by Thursday morning,
followed by considerably colder and drier air. A large high pressure
system centered over the Great Lakes will move eastward into the New
England region and then the Atlantic by this weekend. As it moves
east, it will wedge itself considerably into the mountains and cause
a change in wind direction from northerly to easterly/northeasterly.
A pressure gradient will form with this wedge and bring winds up
with gusts between 10-15 mph for parts of the latter half of this
week. While high temperatures will generally be in the 60s, Friday
morning will have the coldest morning temperatures. On this morning,
temperatures will be in the mid-30s along and west of the Blue Ridge
and in the lower 40s east of the Blue Ridge. With mostly clear skies
expected with this high pressure, this begs the question: will there
be frost? Current answer leans on "yes" but its spatial coverage
will be heavily dependent on the behavior of the winds. Patchy frost
will be possible along and west of the Blue Ridge, where it will be
the coldest, but winds may be just subtly strong enough to prevent
any widespread frost. Temperatures aloft are also forecast to be
relatively warmer in the upper 30s to mid-40s so mixing could put a
dagger in frost development. As the wind estimates are narrowed
down, confidence on frost and any potential Frost Advisories will be
assessed.

.LONG TERM /SATURDAY THROUGH TUESDAY/...
As of 200 PM EDT Tuesday...
Key Message:
1) Coastal low brings questionable weather pattern next week.
A 500mb shortwave in the Deep South will move into the Atlantic and
interact with a cold front to form a coastal low. While model
guidance is in strong agreement with the formation of this low,
models disagree on its movement. Uncertainties of how the upper
level flow will influence the trajectory of this low plague most of
this forecast period. The coastal low could go into the mainland,
move along the coast, or stay out into the ocean and each of these
scenarios have different impacts on precipitation chances,
cloud cover, and wind speed for the region. This will be closely
monitored for any potential impacts to the area, but at the
moment most likely scenario points towards mostly dry conditions.
&&
.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
As of 930 PM EDT Tuesday...
Widespread cloud cover, though it currently remains above 3kft,
so VFR is the order of the evening. Light rain showers will
continue for most of the night, dissipating on Wednesday morning
in concurrence with a frontal passage. Given the modest nature
of the rain, vsby will most likely not be impacted by the rain.
Given the excess ground moisture and increasing stability
towards Wednesday morning, patches of fog are possible, likely
impacting BLF/LWB/BCB. The overcast cloud conditions will act to
hinder fog development a bit though, hence the decision to only
include patches in the forecast. Clouds will lower in the
morning, bringing most sites in the mountains sub-VFR.
Wind pattern will see a shift from southwesterly to northerly
along with the cold front`s passage Wednesday morning. With the
wind shift will come an increase in speed. The northerly winds
will reach 8-12 kt for most of the region, gusting up to 18 kt
in the upper reaches of the mountains (LWB being most impacted).
Confidence in the above forecast is average.
EXTENDED AVIATION OUTLOOK...
Extended period of dry weather becoming more likely. This will
result in widespread VFR. With a drier airmass arriving, fog
development should become less of a concern.
