Synopsis
Unsettled conditions will continue this afternoon as an upper
level trough crosses the local area from the west. Conditions
improve on Friday. Warmer temperatures and chance for showers
and thunderstorms will return over the weekend. A cold front
will approach from the west on memorial day.

Near term until 6 pm this evening
Complex lo pres was found over the ERN conus... One center invof
oh... The other just off the delmarva. A dry slot has surged ne
into the fa this morning... Resulting in at least partial
clearing and diminished pops. Upper level low will be tracking
by just N of the local area... W a trough crossing the region
this afternoon evening... Which will steepen lapse rates and lead
to development of isold-sct convection. Fa remains under
marginal risk svr from spc... Main threats from any stms will be
gusty winds hail. Otherwise... Vrb clouds partly sunny... And
warmer W SW winds 10-20 mph. Highs in the m70s W of i-95 to
the u70s to around 80f across eastern portions of the fa.

Short term 6 pm this evening through Saturday
The upper low continues to lift NE across ERN pa ny new england
late tonight into fri. Drier conditions finally arrive as deep
layered wnw flow develops over the region. Some lingering mid-
level energy could result in sct-bkn CU mid afternoon fri.

Otherwise... Drier and breezy with highs in the upr 70s to low
80s, after morning lows in the mid 50s W to low 60s at the
coast.

Weak ridge aloft nudges into the region from the wsw Fri night
into sat. Differing potential timing in arrival of weak S w
tracking into the fa by Sat afternoon. Combination of daytime
heating and that S W in wnw flow aloft may result in at least
sct convective development. Otherwise... Partly cloudy fri
night-sat morning... Then becoming mostly cloudy Sat afternoon.

Lows from the upr 50s NW to the low 60s se. Highs Sat from the
mid upr 70s-around 80f on the eastern shore to the mid 80s
inland.

Long term Saturday night through Wednesday
Long term period starts off Sat night into Sun with a warm front in
the vicinity and plenty of energy passing through the wnw flow
aloft. This will lead to a chance of shras tstms everywhere, with
low temps in the 60s Sat night and high temps in the low mid 80s
sun. Continued chance of rain into Mon with a weak cold front
passing through the area. Highs again in the low mid 80s. Drier
weather into Tue and Wed behind the front, but still cannot rule out
the chance of a shra or TSTM with continued cyclonic flow aloft.

High temps in the upr 70s to mid 80s both days.

Aviation 15z Thursday through Monday
Showers ahead of a cold front will continue to lift NE and exit
eastern locales including ksby by 12-13z. Conditions will
improve toVFR once the front passes. Additional showers and
thunderstorms are expected to develop this afternoon as an
upper trough moves overhead. Reduced flight conditions are
possible.

DrierVFR wx returns by Fri as weak high pressure builds over
the region. Unsettled conditions return for the weekend when
another frontal boundary affects the mid atlantic states.

Marine
Latest msas has the frontal boundary stalled just south of the
albemarle sound westward to a cold front crossing the mts. The
boundary is still progged to lift north as a warm front this morning
before the cold front crosses the waters this afternoon and evening.

Once again, a challenging forecast as the models continue to show
different solutions with respect to the frontal movements. Thus,
will basically keep the current forecast going with some minor
changes made to the grids and headlines.

Consensus suggests several bouts of SCA level winds over the next 24-
36 hours. Thus, elected to keep just one headline through Friday to
cover the winds but tweaked directions a bit based off the
frontal movements. SW winds 15-20 kts through this evening
become west at the same speeds late tonight and Friday as the
cold front moves offshore. Went ahead and added SCA to the
currituck sound. Data also supports 15-20 kts today across the
lower james river so added a SCA headline there. Current sea obs
in line with wna forecast in keeping 4-5 ft seas through Friday
across the coastal waters (highest out near 20 nm).

Weak high pres builds in for late Fri leading to improving marine
conditions. Sub-sca conditions expected Fri night into the weekend.

Tides coastal flooding
The continued onshore flow combined with high astro tides will
result in elevated water levels through Friday. The sse winds
continue to pile up the water across the middle ches bay so
based off the latest data, went ahead and extended the coastal
flood advisory for the bay side of the lower md eastern shore
for the next high tide cycle. Also issued coastal flood statements
for the va northern neck and atlantic coastal waters from oxb-cape
charles for levels approaching minor flood levels. See cfwakq
for more details.

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.
