Synopsis
High pressure becomes centered off the northeast coast tonight and
Thursday. Low pressure and associated frontal boundaries track
across the region Friday. High pressure builds over the area for the
weekend.

Near term /until 6 am Thursday morning/
High pressure moves off the northeast coast resulting in the low
level flow becoming e-ne tonight. Clearing next few hours with
mainly clear skies this evening then increasing clouds after
midnight, especially across the piedmont. Cooler with lows
ranging from the upr 30s to near 40 north, low-mid 40s south.

Short term /6 am Thursday morning through Saturday/
H5 ridge becomes centered off the coast Thursday. Tsctns show
moisture at various levels due to WAA atop the stable onshore flow.

Expect partly cloudy skies east, mstly cloudy to cloudy west with
any upslope shwr activity remaining west of the fa. Given weak/low
mixing and the cloud coverage, expect a cooler day with highs 55-60
except 50-55 at the beaches.

Moisture increases late Thursday night ahead of approaching upr
level low. Will keep the evening dry with shwrs overspreading the
area after midnight. Pops range from chc along the coast to likely
across the piedmont. Lows in the low-mid 40s.

Rather challenging forecast Friday as the models continue to prog a
strong closed low to become negatively tilted as it crosses the
region. Main sfc low to track north of the fa but data suggests
another spoke of energy will rotate arnd the main low resulting in a
triple point low crossing northern va Friday afternoon and evening
before moving off the nj coast Friday night. Copious amounts of
atlantic moisture forecasted ahead of the low along with pw's btwn
1.25 to 1.50 inches. This will lead to locally heavy downpours
Friday. Challenge for the afternoon will be the amount of convection
that develops. SPC has the southern half of the fa in a marginal
risk but a lot of uncertainity remains on just how unstable it
becomes. Thus, categorical pops will be maintained across the fa
with thunder chcs limited to the afternoon and mainly across the
south. Slght chc thunder across the north. Temps tricky and may
depend on any heating that occurs. Highs in the 60s except near 70
southern most zones.

Likely to categorical pops continue Friday evening with pops
tapering off after midnight as the low pulls offshore. Thunder chcs
will be limited to the evening and mainly across the south and
east. Lows in the upr 40s-mid 50s.

Trailing upr level energy tracks across the eastern shore early sat.

Will keep slght chc morning pops there, otw decreasing cldns. Highs
in the low-mid 60s eastern shore, mid 60s-lwr 70s west of the bay.

Long term /Saturday night through Wednesday/
Weak high pressure returns to the region Sat night/sun with
nw flow aloft. Mostly clear skies and cool temperatures
anticipated with lows in the 40s Sat night and highs in the 60s
sun (upper 50s atlantic beaches). High pressure slides offshore
sun night/mon as the next low pressure system deepens over the
arklatex region/lower mississippi valley. The low continues to
track NE into NRN oh/pa Mon night into tue... Dragging a cold
front through the mid atlantic region Tue aftn/evening. Increasing
cloudiness late Sun night into Mon with similar temps to sun. Lows
in the 40s Sun night, and highs in the 60s Mon (upper 50s atlantic
beaches). Sfc pressure gradient tightens substantially late mon
night into Tue ahead of the approaching cold front. S-w winds
gusting up to 25-30 mph will be possible. Widespread rainfall is
anticipated during this timeframe with very low thunderstorm
chances due to rain occurring primarily in the morning. Warmer
temperatures Mon night/tue as a warm front lifts north through the
region. Lows Mon night in the mid-upper 40s far NRN counties (i.E.

North of the warm front) and in the lower 50s elsewhere. Highs
tue in the 60s far NRN counties and in the lower 70s elsewhere.

Aviation /19z Wednesday through Monday/
High pressure ridge extending from a center over the james bay south
into the mid atlantic states will slip slowly to the east. Strong
low pressure over the southern great plains will move northeast into
the ohio valley by Thursday night.

Stratocumulus over interior virginia and north carolina will
continue to erode from north to south. Have ric phf and ecg with
MVFR CIGS for the first couple of hours of the 18z taf. The sky will
be mostly skc this evening and overnight. Layered cloudiness
increases from the west on Thursday but will remainVFR through 18z.

No visibility issues are indicated through Thursday morning.

Winds will be from the north and northeast at around 10 knots during
the balance of the afternoon. Winds will be less than 5 knots from
the northeast and east overnight and mainly easterly 5 to 10 knots
on Thursday morning.

Outlook... The aforementioned low pressure system will move from the
ohio valley across northern portions of the mid atlantic states to
south of new england by Saturday morning. Widespread rain develops
Friday morning which will combine with a chance for thunderstorms
Friday afternoon and evening. Periods of MVFR/ifr will be
likely. Conditions improve by Saturday morning. High pressure
builds back into the area for the weekend. There will be a
chance for showers western portions of the area by late Monday
as the next system develops over the mississippi valley.

Marine
High pressure continues to build into the region from the north
tonight and slides across the DELMARVA on thu. Breezy nne winds
10-15kt through early evening will diminish around sunset. Although
a diurnal increase in winds is anticipated late tonight into thu
morning, persistent onshore/ne-e winds will remain AOB 15kt through
thu. However, seas could reach up to 5ft out near 20nm in nne swell
and have issued SCA flags for all coastal waters from 500am through
700pm thu; may be able to drop headlines with forecast package late
thu aftn.

High pressure slides offshore Thu night as an approaching low
pressure system tracks over the great lakes states. Winds become
more SE overnight. Speeds still AOB 15kt with seas 3-4ft/waves 2ft.

The sfc pressure gradient tightens on Fri as a warm front lifts north
across the area Fri morning ahead of an approaching cold front, which
is expected to cross the waters Fri evening. Wind speeds are expected
to increase to low-end SCA (15-25kt) Fri morning... Becoming sw-w and
decreasing AOB 15kt Fri evening with the cold frontal passage. Seas
also build to 5ft Fri morning and could reach up to 6ft NRN coastal
waters Fri aftn... Primarily due to onshore swell. Elevated seas around
5ft expected through Fri night... Possibly lasting through Sun for far
nrn coastal waters. Waves on ches bay should average 2-3ft on fri.

Weak high pressure returns to the region sat/sun with northerly winds
aob 15kt Sat and AOB 10kt sun. Seas 3-5ft far NRN coastal waters/2-4ft
srn coastal waters. Waves generally 1-2ft.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
