.SYNOPSIS...
High pressure will build southward from eastern Canada through
much of the week. Meanwhile, Tropical Depression Nine near the
Bahamas is expected to approach the Southeast coast early this
week before stalling then drifting out to sea through mid week.
A strong cold front will track across the area by the middle of
this week bringing cooler and drier weather.
&&
.NEAR TERM /THROUGH TONIGHT/...
Dense fog west of the Blue Ridge has started to lift, with most
of it being very low stratus now and some patchy ground fog
remaining. This should dissipate in the next 1-2 hours, with
abundant sunshine by noon time.
Dry conditions expected today as highs reach the upper 70s to
low 80s. Mostly clear tonight, except for thin high clouds
spreading northward from TD Nine. Overnight lows the upper 50s
to mid 60s.
&&
.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
Mid-high level clouds will continue to expand northward during
the day Monday as TD Nine approaches the southeast coast. The
latest model trends continue to show TD Nine moving slower and
staying further offshore. Despite this slower and further
offshore track, rain is still expected to affect central VA
Monday afternoon and Monday evening and may reach areas as far
north as I-66. However, the risk of excessive rainfall continues
to diminish for areas of central VA and southern MD. By Tuesday
morning, drier air will start pushing south again on
strengthening northerly winds between TD Nine and building high
pressure over Ontario/Quebec region. Clearing will then take
place Tue night. Low-level thicknesses begin to drop sharply Tue
evening signaling a significant change in air mass/frontal
passage for the middle portion of the week.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
A northern stream trough descending across New England will send a
dry front southward during the middle of the week, with strong
Canadian high pressure building behind it. This will shunt any
clouds and moisture southward and lead to declining temperatures and
dew points. Near normal temperatures Wednesday will drop below
normal Thursday and Friday. Highs will only reach the 60s. Dew
points falling into the 40s will support similar lows for much of
the area (remaining in the lower 50s near/east of I-95, while 30s
will be possible in the higher elevations.
The consensus forecast keeps high pressure through the upcoming
weekend, gradually drifting east. Combined with rising heights, this
would lead to a warming trend. While unlikely to occur, there are
still a few rogue solutions that have what becomes of TD 9 not being
affected by the midweek trough, stalling, and then somehow affecting
the east coast next weekend. Stay tuned to hurricanes.gov for the
latest official forecast from the National Hurricane Center.
&&
.AVIATION /14Z SUNDAY THROUGH THURSDAY/...
Low clouds and some lingering ground fog will burn off by 16Z.
VFR conditions and fair weather is expected after. Some
additional fog is possible late tonight at CHO and MRB.
Otherwise, VFR conditions are expected through Wednesday
morning. A few light rain showers possible at CHO Monday
afternoon and evening.
VFR conditions are expected Wednesday and Thursday, but some north
to northeast wind gusts to 20 kt are possible as strong high
pressure builds into the area.
&&
.MARINE...
Winds have dropped below SCA levels and will remain that way
through tonight. Winds begin to strengthen again Monday through
at least the middle of next week, with SCA conditions possible
in parts of the water starting Tuesday morning.
Strong high pressure will build north of the area Wednesday and
Thursday while a tropical cyclone remains well to the south. The
gradient between these systems may result in Small Craft Advisory
conditions in north to northeast winds.
