Planning to drive down to Carolina Beach south of Wilmington tomorrow.  I figure it will be better to drive through the storms in NC than have to load up the car here in the rain Friday morning.  

Any excuse to get 1 extra day at the beach feels like right call

I guess we know where the L is going based on the NAM. Right over my house :(

The NAM and ECMWF are both bouncing around quite a bit with the position of the center as the remnants move north across Va/WVa. The GFS and GEM are most consistent with the NHC up the Shenandoah Valley.

Makes no difference,  if the NHC general track verifies it will be wonderful!   That would give western areas suffering tremendously from drought a multi-million dollar rain.  Many millions of dollars worth of crops have already been lost.

This will indeed be a God-Send for starving livestock who are also having water hauled in to them daily because ponds and streams that normally supply water are dried up.

Hopefully, this will signal a change in the long term pattern.

4pm afternoon AFD from LWX about Debby

SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
The remnants of Debby will start to lift northward tomorrow as
it begins to feel the influence of troughing well off toward the
northwest over the Great Lakes. While the main circulation
associated with the remnants of Debby will remain off to our
south during the daylight hours tomorrow, a weak lobe of shear
vorticity in the mid-levels to the north of Debby will lift
northward through locations to the east of the Blue Ridge.
Differential cyclonic vorticity advection ahead of this feature
may provide enough lift to initiate some showers and
thunderstorms tomorrow morning through the first half of the
afternoon. Any storms tomorrow morning may be capable of
producing very heavy rainfall within what will be a tropical
airmass characterized by precipitable water values over two
inches. Confidence was too low for a Flood Watch to the east of
the Blue Ridge at this time, but one may eventually need to be
considered for during the day tomorrow. To the west of the Blue
Ridge, showers and a few thunderstorms can`t be ruled out, but
much of the day should remain dry.

Tomorrow night attention will turn to the remnants of Debby as
it lifts northward and starts to interact with a trough off to
our northwest. The main core of the system is expected to lift
northward from central Virginia through the Shenandoah Valley
and Potomac Highlands tomorrow night. Very heavy rainfall is
expected over those locations tomorrow night into the first half
of Friday. A Flood Watch for flash flooding has been issued for
those locations, where a widespread 3-5 inches of rain is
expected, with isolated totals of up to 7 inches. To the east of
the Blue Ridge, much of the night may remain dry as Debby`s
remnant circulation passes off toward the west.

Another concern tomorrow night and into the day Friday will be
tornadoes. With the system`s surface low taking a track over the
Alleghenies, a very favorable shear profile and limited
instability will move northward across central Virginia and the
Shenandoah Valley tomorrow night. SPC has expanded both the
Marginal and Slight risks northward through our area to account
for this potential tornado activity tomorrow night.

As we move through the day Friday, the system`s surface low will
lift northeastward across PA. As it does so, a southward
trailing convective line will track eastward across locations to
the east of the Blue Ridge. This line of storms may be capable
of producing very heavy rainfall, as well as tornadoes. Since
this convective line will be a smaller scale feature, we have
decided to hold off on issuing a Flood Watch to the east of the
Blue Ridge for the time being. The line of storms associated
with the remnants of Debby should progress east of the area
Friday evening, with dry conditions expected during the second
half of Friday night.

They do have good food and good drinks. Kids liked the train hanging from the ceiling. First raindrops of the day now falling at my location. 

Yeah I love  the big 3 right there !

Fisherman's for finer  dining and their Rockfish Tidewater which is unmatched

Crab  Deck for great crabs out over the water . $60dz last week for mediums and all heavy with a few larges.

Harris for incredible oyster buffet in fall and winter.
