Synopsis
High pressure remains centered just off the mid atlantic coast
through tonight. Low pressure will track from the gulf coast
states northeast up along the east coast late Monday through
midweek.

Near term through tonight
As of 1025 am edt Sunday...

latest sfc analysis shows ~1030 mb high pressure centered just
offshore. The high also extends up into the great lakes region.

To the west, a potent upper level closed low continues to slide
slowly east across the southern plains toward the lower
mississippi river valley, with an inverted surface trough
developing over the west-central gulf coast region. Late morning
msas data showing pressure falls over the deep south, in the
vicinity of developing sfc low pressure in E louisiana into ms.

It is this feature that will slowly lift our way tonight through
Monday, bringing increasing rain chances later Monday evening
through midweek.

For today, noting some increasing high cirrus over northern
portions of the area. Will continue to see mid to high clouds
increase through the afternoon, especially inland. However, will
nonetheless see another dry, pleasant day with comfortable
temperatures. Nudged high temps up slightly for the afternoon,
mainly in the upper 50s to low 60s along the immediate coast to
upper 60s to around 70 inland.

Local area remains under the influence of sfc high pressure
positioned just off the coast. Another dry night with any pcpn
staying well w-sw of the local area. Expect a partly cloudy sky
with low temps ranging through the 40s.

Short term Monday through Tuesday
As of 350 am edt Sunday...

unsettled wx pattern shaping up this week as low pressure
ejects east from the nations mid section and into the tenn
valley by late mon. Models prog a potent SRN stream S W around
the base of the long wave trof Mon night then move it NE to
near the carolina coast tue. This keeps the local area on the
cooler side of this system with a general rain expected to
overspread the area.

Keeping most of Mon dry except for some low chc pops after 18z
across the far swrn zones. Otw, bcmg cloudy with highs in the
60s except for upr 50s at the beaches. Rain overspreads the fa
mon night except for the lwr md ERN shore where it may take
until 12z Tue to reach. Pops ramp up to categorical south of
i64, likely-chc pops to the north. Lows Mon night mid 40s NW to
mid 50s se. Tue looks wet with cat likely pops throughout the
day. Enough lift gulf of mexico moisture noted for some areas of
mdt to heavy rain. Highs Tue upr 50s NW to mid 60s se.

Long term Tuesday night through Saturday
As of 350 pm edt Saturday...

after the main area of rain exits the region between 6-12z
Wednesday, we should see enough sunshine for temperatures to warm up
to around 70 Wed pm. 21 12z gfs ECMWF have showers lingering
throughout the day on wed, so kept pops between 50-60%. GFS even
hints at the possibility of a few thunderstorms Wed afternoon. Most
recent guidance has backed off on the rain Thursday-Friday am. Ecmwf
has the most qpf, and the best chance of rain looks to be over
southern eastern portions of the cwa. Thus, have lowered pops to
below 30%. Highs between 68-74 lows around 50 expected thu-fri.

A potent 500mb shortwave is forecast to track over the northeastern
us Friday into the weekend. This will set the stage for another
chance of rain late Friday-Saturday as well as another shot of
below average temperatures. Still quite a bit of uncertainty
regarding the strength timing of this storm system. Highs in the 60s
on Saturday with lows dropping into the 40s Sunday am.

Aviation 18z Sunday through Friday
As of 145 pm edt Sunday...

vfr through the 18z TAF period. Expect E SE winds at 5-10 kt
this afternoon. Few CU possible at ~5k feet through 22-23z for
ric sby ecg. High clouds gradually lower after 12z Monday from SW to
ne. Winds increase out of the E to 10-15 kt during the day Monday.

Outlook: expect conditions to deteriorate from SW to NE Monday
night as a large area of rain approaches the cwa. This will result
in flight restrictions throughout the day Tuesday at all terminals.

Restrictions will likely last through ~12z Wed before conditions
slowly improve during the day.

Winds remain E for all sites at ~10 kt through 9z tue. East winds
increase to between 15-20 kt (gusts to ~25 kt) at orf phf sby ecg
during the day on Tue and last through 0z wed. Slightly lower
winds (e at 10-15 kt) expected at ric during this timeframe.

Winds decrease after 00z Wed and turn to the SW by Wed afternoon.

Marine
As of 350 am edt Sunday...

high pressure centered over new england and atlantic canada
will prevail across the region today. A S SW wind of 5-10kt this
morning will become SE by this aftn. High pressure pushes off the
srn new england coast Monday and Tuesday as low pressure lifts from
the deep south into the tennessee valley. This will result in
increasing onshore flow. An E wind is expected to reach 10-15kt by
Monday, and then 15-25kt by late Monday night Tuesday Tuesday
evening, with the potential for 25-30kt S of the va nc border
Tuesday. Onshore flow will result in seas building to 5-9ft
Tuesday Tuesday night, with 4-6ft waves in the mouth of the bay (3-
5ft elsewhere in the bay). Broad low pressure crosses the region
Wednesday with the wind becoming NW in the wake of the low. A cold
front approaches from the W later in the week.

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.
