Synopsis
A frontal boundary will remain nearly stationary near the
virginia, north carolina border today into tonight, then
lifts back north and across the area as a warm front during
Tuesday. A stronger cold front will cross the region Wednesday
into Wednesday night.

Near term until 6 pm this evening
As of 425 am edt Monday...

sctd showers and tstms continued to affect much of the region
overnight, with heavy rains from tstms occurring over fluvanna
and esply louisa county. As of 400 am, rainfall amounts of 2.5
to 3.0 inches had occurred over portions of ERN louisa county.

Activity over the CWA should diminish during the morning hours,
but then more sctd showers and tstms will re-develop over most
of the region except the NE counties this aftn. A few stronger
storms will be possible over scntrl va into interior NE nc,
where the best instability will be located. Highs today will be
in the lower to mid 80s. The pcpn will diminish or end this
evening into tonight, with the main energy lift then shifting
to the S and W of the region where the frontal boundary will
start to lift back north as a warm front.

Short term 6 pm this evening through Wednesday
As of 425 am edt Monday...

the front will lift back nwd and across the region as a warm
front during tue. This will occur as stronger surface low
pressure organizes in the upper midwest, and moves NE across the
great lakes by Tue evening. Chances for showers tstms will
increase again over the entire region during tue. Highs on tue
will mainly be in the mid 80s.

A cold front approaches from the NW Tue night, and pushes across
the region Wed into Wed night. The primary moisture plume will
be pushed offshore, and pops will be lower (20-40%) with the
frontal passage wed. Lows Tue night will be in the lower to mid
70s followed by highs on Wed in the mid to upper 80s.

Long term Wednesday night through Sunday
As of 400 pm edt Sunday...

drier and much cooler weather settles in Thursday, with only
slight chance pops remaining across nc through mid-morning. 1024
mb high moves east over the mid-atlantic Thu pm thru mon. 850mb
temps in the +9 to +11 degc range spell out quite the cool
down, with surface temps staying in the low 80s thu, low-mid 80s
fri, and warming into the mid-upper 80s through the weekend.

The only portion of our area with marginal rain chances fri-sat
will be in NE nc, where ridging will be slightly weaker. 12z gfs
wants to break down high pressure quicker, allowing for a few
showers over nc SE va on Sunday... Consider that solution tbd.

Otherwise, dew points will be lower late week into the weekend,
helping to make sensible weather more pleasant. Outdoor plans should
fare well for the most part late week through the weekend, and into
the start of next week.

Aviation 08z Monday through Friday
As of 330 am edt Monday...

unsettled conditions will continue across the region the next
couple of days, as a frontal boundary remains nearly stationary
near the va nc border today into tonight, then lifts back north
and across the area as a warm front during tue. This will result
in continued chances for showers and tstms at all TAF sites,
along with MVFR ifr conditions due to the moist airmass and any
heavier showers or stronger tstms.

Outlook... Chances for showers tstms and lower CIGS vsbys will
continue Tue night into Wed evening, as the warm front lifts
well north of the region, and a prefrontal trough followed by a
cold front pushes into and across the region. High pressure
builds into the area for Thu into next weekend.

Marine
As of 330 am edt Monday...

this Monday morning winds were generally E to NE across the bay
and waters as a weak frontal boundary was sagging south into ne
nc. The front will stall over NE nc this morning, before coming
back northward as a warm front late tonight and Tuesday. Winds
remain generally NE to E behind the front generally around 10 kt
though there could be times where winds gust up to 15 kt.

Appears strongest winds, remain mainly in the 12-16 kt range,
across the northern and central portions of the bay, and the
northern half of the coastal waters. However, winds waves seas
should remain below SCA criteria. An easterly swell was sowing
up at buoys from chincoteague north to fenwick island with seas
building to 3 to 4 ft despite relatively light winds of 10 kt.

This swell will persist and may push a little farther south of
just offshore of CAPE charles and CAPE henry later today.

Winds are expected to decrease for a time Monday night early
Tuesday as warm front lifts northward, then increase
significantly from the south Tuesday afternoon night ahead of
stronger cold front approaching the area from the west. Winds
increase aloft and with mixing expect winds to be a bit gusty at
times Tuesday. Winds persist Tuesday night. If models remain
consistent, SCA will likely be needed in the 00z Tuesday into a
portion of Wednesday. A stronger cold front moves late Wednesday
with a winds shift from S and SW to NW and N in the evening.

Model cold advection suggest winds are underdone in the models
behind the front, and would anticipate a period of SCA winds on
the bay in the Wednesday night Thursday time frame in the
northerly flow.
