Synopsis
Low pressure along the nc coast this morning slides north
through the local area today. Drier weather is expected Friday
through the upcoming weekend.

Near term through tonight
As of 405 am edt Thursday...

latest upper air analysis places an upper trough slowly taking
on a neg tilt in place over the lower mid-atlantic region this
morning. At the sfc, latest analysis places developing sfc low
pressure over SE nc early this morning, W the associated sfc
warm (coastal) front extending to the n-ne across coastal nc.

Regional radar mosaic showing light rain or drizzle over the
delmarva and extending back into central va. More organized area
of moderate to locally briefly heavy rainfall continues to lift
north across north central NE nc this morning, with strong,
narrow area of upper level divergence low to mid level fgen
convergence. Hi- res data is very consistent in pivoting this
area of rainfall through the area this morning, with rain
chances slowly tapering back for the southern and central zones
as mid-level dry slot lifts north across the area. Precip will
take longest to end north of ric metro, with scattered showers
likely lingering into the mid to late afternoon before drying
out Thu night. However W a potent S W aloft passing through the
area, and with plenty of lingering llvl moisture, expect
conditions to generally remain mostly cloudy lingering low
clouds dz across the north, gradual clearing across the south.

Highs mainly in the l-m50s... Except l60s possible over far se
va-ne nc. Lows mainly in the 40s (some upper 30s possible W of
i-95).

Again held out TSTM mention, with any aftn convection likely to
remain over central SE nc with trailing vort lobe sliding
across to the south of the local area.

Short term Friday through Sunday
As of 405 am edt Thursday...

vrb clouds partly sunny N and central areas... Mostly sunny far
s and SE fri. Sfc low will be exiting across new england as
strong high pressure builds to the west. Compressed pressure
gradient will result in gusty wnw winds to 25-40 mph (noted in
hwo) for Fri aftn and evening. A wind advy may be needed for a
portion of the area, but for now, an hwo mention and gusty
winds in the digital forecast will suffice. One final trailing
s W aloft is then expected to dive SE from the upper midwest and
will keep ~30% pop in the aftn across the northern neck and
eastern shore for some sct showers. Otherwise, expect downslope
flow will scour out any lingering showers, with little more than
some sprinkles possible over the local area. Given slim chances
of measuring in this set up, will maintain pops at slight chc
or less. Highs in the m-u50s N to the l60s central and s. Mostly
skc Fri night with lows in the 30s (w winds lowering... Esp
inland).

Weekend is looking to be dry, as high pressure to the west
slowly builds over the southeast, with gradually warming temps
as return flow sets up W sfc high sliding offshore by Sunday.

Long term Sunday night through Wednesday
As of 225 pm edt Wednesday...

by mon... That sfc hi pres will be off the SE CONUS coast while
low pres and its associated cold front will be starting to take
shape gather moisture from the oh valley to the lower ms
valley. The cold front will be pushing S through the area mon
night into Tue morning W a trailing area of lo pres tracking by
to the S as colder sfc hi pres builds SE out of canada. The
12z 20 continues to show potential for mixed pcpn tue
afternoon evening as lo pres exits the carolina coast... But
remain wary of that possibility given the fact that each time
cold air has chased ra this winter... There was very little or no
sn. Maintained pops to 50-80% (for ra) across much of the fa
mon night into Tue morning then begin to taper the pops down
from NW to SE into Tue night. Dry cool wx expected wed.

Highs Sat in the l50s at the coast in va-md to the u50s around
60 f inland. Lows Sat night in the l-m30s inland to 40-45f at
the coast. Highs Sun in the u50s-l60s near the bay and on the
ern shore to the u60s-l70s elsewhere. Lows Sun night in the
m-u40s. Highs Mon from 60-65f near the bay and on the ERN shore
to the u60s-l70s inland. Lows Mon night in the u30s NW to 45-50f
se. Highs Tue in the m-u40s N and NW to mainly the m50s se.

Highs Wed in the u40s-l50s N and NE to the m50s s.

Aviation 12z Thursday through Monday
As of 655 am edt Thursday...

latest analysis reveals developing low pressure spinning just
off the NE nc coastline. Sub-vfr conditions continue over much
of the area with diminished vsby in radz and patchy fog, with
low stratus bringing ifr ceilings currently across SE va
including phf ric, with low end MVFR tempo ifr CIGS elsewhere.

Next round of showers will lift across the area over the next
few hours, eventually impacting all TAF sites. High- res model
guidance has done well with showing small window ofVFR as low
pressure and sfc boundary lift north, with ceilings to quickly
deteriorate again at all sites by later this morning. Diminished
visbilities are likely with brief periods of vsby as low as 2sm
in any heavier rain showers. E to NE winds increasing to around
10 to 15 knots by mid-morning, and turning southerly, as the
low tracks inland.

Outlook: drier air arrives from the NW tonight. However, a
secondary trough drops across the region Friday, which has the
potential to bring a gusty NW wind, clouds, and a few light
showers (mainly sby and possibly ric). High pressure builds
across the region Saturday into Sunday.

Marine
As of 405 am edt Thursday...

early morning surface analysis shows high pressure well northeast of
the local area continuing to head eastward and farther out to sea as
low pressure over the eastern carolinas translates nne. Winds over
the bay and northern offshore zones are generally out of the
northeast at 5-10 knots while areas farther south are southeasterly
at 10-15 knots. Waves in the bay are currently 1-2 feet with seas
offshore 5-8 feet S and 4-6 feet n. Waves will increase to 2-4 feet
by early afternoon with 5-8 foot seas expected offshore.

Southeasterly winds will increase to 15-20 knots over the bay and
lower james river and 15-25 knots offshore through the morning as
low pressure approaches the area. The low will move nne through the
area today and will pull north of the region this evening, allowing
winds to become westerly in its wake. It now appears that a period
of sca-level westerly winds will occur over the bay overnight with
15-20 sustained and gusts to 25 knots. There will be a lull in winds
this afternoon but went ahead and extended small craft headlines for
the bay into Friday to cover the forecasted re-intensification
of winds tonight. Chose not to extend the headlines for the
currituck sound or lower james river with this package but the
day shift may opt to include the lower james tonight with a
favorable westerly component to the wind. Winds across the
northern offshore zones will generally be in the 20-25 range
with gust approaching 30 knots with 15-20 and gusts to 25 knots
across the southern zones tonight.

The aforementioned surface low will deepen considerably over the
northeastern CONUS on Friday with continued west and northwesterly
flow over the region. A surge of CAA will accompany a steep pressure
gradient and allow winds to increase Friday night and into Saturday.

Extended all bay and offshore SCA headlines into Friday evening with
the potential for gale conditions over the northern ocean zones
Friday night into at least the first half of Saturday. Seas remain
elevated through most of Saturday so at least SCA headlines can be
expected to continue into Saturday evening before conditions finally
calm down. Sunday and Monday appear to be relatively tranquil with
winds becoming southwesterly ahead of another area of low pressure
to our west. A strong cold front is forecast to cross the waters
Monday night and Tuesday with robust north winds in its wake.
