Synopsis
A warm front lifts north of the area later today as high pressure
becomes centered off the southeast coast. A cold front crosses the
region Monday night. High pressure returns Tuesday and Wednesday.

Near term until 6 pm this evening
As of 650 am edt Sunday...

will keep low chc pop across oxb next hr to account for exiting
comvection.

Latest msas has high pressure off the new england coast as well
as near the fla panhandle. In btwn, a frontal boundary remains
nearly stnry just west of the ches bay. Models show the frontal
boundary slowly moving nne as a warm front later today as the
high moves farther off the new england coast. This will put the
area in the warm sector dominated by the SRN high.

Once again, short range high res data offer up different solutions
wrt any convection that develops today. Will be watching two areas,
the first one with the advancing warm front mainly E of i-95 where
data does show enough wind moisture convergence for sct storms to
fire up on aftr 18z. The second will be across the nwrn zones where
some of the convection that pops over the blue ridge drifts se. Will
maintain the low chc pops across the ERN two-thirds of the local area,
although coastal beach areas may be saved from the convection due to
local sea-breezes. The activity across the NW is where SPC has
issued a marginal slght risk for the ptntl for large
hail damaging wind gusts with any strong storm that dvlps.

Appears the best support for svr tstms today remains across nrn
va. Will highlight this in the hwo.

Another summer-like day under pt to mstly sunny skies. Highs upr 80s-
lwr 90s west of the bay, in the 80s near the water, 75-80 beaches.

Short term 6 pm this evening through Tuesday night
As of 330 am edt Sunday...

any on-going convection weakens dissipates after sunset with loss
of heating. Will carry lw chc pops thru midnite across the ne, otw
a warm and humid nite ahead. Lows 65-70.

Monday starts off mstly sunny, then becomes pt sunny with chc late
day eve convection tracking nw-se ahead and along a cold front that
is progged to push offshore arnd 06z. Models show limited moisture
for this front to tap, so will carry low chc pops attm. Remaining
hot ahead of the front with highs upr 80s-lwr 90s except low-mid 80s
at the beaches. Decreasing clouds and turning cooler Mon nite. Lows
upr 50s NW to mid 60s se.

Sunny cooler Tue as high pressure builds in from the north. Highs
mid 70s north to lwr 80s south. Mstly clr comfy Tue nite. Lows low-
mid 50s north to upr 50s-lwr 60s south.

Long term Wednesday through Saturday
As of 330 am edt Sunday...

an upper-level ridge centered over the SE us will dominate the weather
pattern for much of the extended forecast, bring hot and dry conditions.

Wednesday will be the beginning of the warming as a high pressure NE of
the area moves well off of the new england coast. Areas near the coast
will remain in the 70s with an onshore flow, while inland areas will
reach around 80.

Pops of 20-30% we added for Thursday for an slight chance of a showers
or thunderstorms as a disturbance moves off the nj DELMARVA coast. Highs
will be near 90 inland and low mid 80s for hampton roads and the eastern
shore, with lows in the 60s.

Friday and Saturday will be the hottest days of the week. The upper-level
high will build northeast over the mid-atlantic and the sfc flow will be
out of nw. With the ridge and downsloping, highs will easily reach the mid
90s, especially in the richmond metro although heat index values may not be
much higher than the actual temp given dp temps in the low-mid 60s. Highs
will get to near 90 at the va and nc beaches and inland eastern shore.

Temperatures at night will not cool off much, lows will be around 70.

Aviation 12z Sunday through Thursday
As of 650 am edt Sunday...

patchy fog stratus at ecg next hr or so thenVFR conditions. A warm
front lifts nne of the area later today. This could spark off an
isltd TSTM across the north east after 18z, but not enuf confidence
to include thunder at any TAF site attm. Winds become south 10-15
kts today.

Outlook...

a stronger SW wind for Mon with late day nite tstms possible ahead
of a cold front. Winds shift to the N Mon night into tue... And will
be fairly strong for a brief period along the coast through midday tue.

Marine
As of 330 am edt Sunday...

clockwise flow around a surface high south of CAPE cod is leading to
south and southeast winds ~10 knots this morning across the marine
zones. Seas offshore are 2-3 ft with 1-2 ft waves in the bay.

The pressure gradient between high pressure offshore and strong low
pressure over the great lakes will allow southeast winds to increase
after noon today. Generally expecting sustained winds around 15
knots with gust approaching 20 knots in the bay, especially at
elevated sensors. Waves briefly build to 2-3 ft while seas offshore
are 2-3 ft S and 3-4 ft n. This event looks to be pretty marginal
and of relatively short duration so will hold off on any sca
headlines with this package. Winds become south and southwest 10-15
knots by Monday morning as a trailing trough cold front from parent
low pressure over the northeast approaches the local area. Ssw winds
10-15 knots in the bay and 15-20 knots offshore will stretch into
Monday evening before the cold front crosses the waters from NW to
se. Models continue to show general agreement regarding a
northwesterly surge of 15-20 knot winds behind the front early
Tuesday morning before decreasing to 10-15 knots by Tuesday
afternoon. Waves will build to 2-3 ft in the bay with 4-5 ft
seas N and 3-4 ft seas s.

Southerly flow returns for the second half of the week with strong
high pressure in control of the local weather.

Tides coastal flooding
As of 645 am edt Sunday...

a few spots in the bay may see water levels approach or slightly
exceed minor flooding (mainly bishops head) with the high tide
cycle tonight.

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.
