Synopsis
Low pressure intensifies off the DELMARVA coast this evening,
bringing widespread rain to the region. High pressure returns
Sunday with mostly sunny skies and seasonable temperatures. A
warm front lifts north through the area Monday and Monday night.

High pressure becomes anchored off the southeast coast Tuesday
and Wednesday bringing a return to well above normal
temperatures.

Near term until 6 am Sunday morning
Current WV imagery depicts the tail of an upper jet progressing
across the NRN mid-atlantic with a trough digging across the
great lakes. At the surface, low pressure is organizing off the
coast of the delmarva. Light rain continues across
central ERN sern va and NE nc with temperatures ranging from
the mid upper 30s N to the low mid 40s SE under a cloudy sky.

Light rain will continue through midnight and then gradually
taper-off through the overnight hours as the primary upper
forcing lifts farther NE and as drier mid-level air arrives from
the NW as low pressure intensifies off the delmarva, and then
heads out to sea by Sunday morning. Lows in lower 30s NW to the
upper 30s lower 40s se. QPF amounts to avg 0.25 to 0.50" N to
0.15 to 0.30" s.

Short term 6 am Sunday morning through Tuesday
Sfc high pressure builds over the region Sunday for a dry mostly
sunny day. Highs mainly from the mid to upper 50s west of ches
bay (warmest south central va), with cooler conditions, mainly
in the in the upper 40s lower 50s close to the coast with light
onshore flow. Models bring next system and a return of moisture
back from the SW by mon. Mostly clear Sun evening with
increasing clouds overnight from SW to ne. Lows mainly 35-40f
though readings may actually rise a bit after midnight across
the west. A slight chance for rain late west of i-95. With the
sfc high well off the mid- atlc new england coast on mon,
overrunning moisture pushes across the local area with mainly
cloudy skies and a light E SE flow. Best forcing remains off to
our NW however, so not necessarily looking at a lot of qpf. Will
carry pops to 40-50% most areas for now. Not a true cad setup,
but a lot of clouds and shallow mixing will keep it cool for
much of the day, especially across the piedmont. Late day highs
will avg 50-55f W NW to the mid 60s far se. Increasing SW flow
mon night as upper ridge axis begins to amplify build off the se
coast.Models indicate some continued light QPF amounts mon
night, but there is little forcing for precipitation so will
genly keep pops capped at just 20%. Milder with little drop in
temperatures due to the SW flow, lows ranging from the upper 40s
to mid 50s. Area will be firmly in the warm sector on tue, with
strong upper ridge centered over the gulf stream off the se
coast. GFS nam depict a lot of low level moisture across the
area so skies may start of mostly cloudy. Suspect the SW low
level flow and 850mb temperatures rising to +10 to +12 c will be
sufficient to scour out the low level clouds by late morning
and allow for a partly sunny day. Highs expected into the 70s
except for locally cooler conditions at the immediate coast.

Long term Tuesday night through Saturday
A strong +2 st dev 500mb ridge will be located over the
subtropical WRN atlantic Wednesday bringing very warm temperatures.

Lows Tuesday night Wednesday morning are forecast to be in the mid
50s to around 60f, followed by highs Wednesday in the upper 60s low
70s over the ERN shore, and at least mid upper 70s elsewhere. There
is the potential for low 80s over SE va NE nc. A weak shortwave
trough is progged to rotate around the ridge Wednesday, and this
could result in some more clouds and low pops (20-30%) over the
piedmont. The ridge slowly breaks down Wednesday night into
Thursday, but remains strong. Therefore, a cold front to the NW will
have slow progress reaching the mid-atlantic. Pops Wednesday night
will range from 20-30% S to 30-40% n, then ~30% S to 50-60% n
Thursday. Lows Wednesday night will mainly be in the 50s, with the
potential for wide ranging highs Thursday possibly around 60f low
60s N to the 70s SE depending on where the cold front reaches. Upper
level ridging will continue to prevail but gradually weaken off the
southeast coast later next week into next weekend with well above
normal temperatures continuing. There remains some uncertainty with
the cold front, with the general consensus for the front to be into
nc Friday with highs in the 50s to low 60s, and then lifting back n
as a warm front with highs in the 60s to around 70f by Saturday.

Forecast pops are mainly 20-30% Thursday night through Saturday.

Aviation 03z Sunday through Thursday
Widespread MVFR ifr conditions as low pressure system just off
the coast and upper level cyclonic pattern pushes light to
moderate rain through the region. The low is forecast to
continue NE over the waters overnight and the rain will
eventually move off the coast before daybreak as high pressure
moves into the area. Ceiling and visibility conditions will
slowly improve through the night and likely becomeVFR between
midnight and 4:00 am. Winds will mostly be light less than 10 kt
during the overnight and shift to the NW and ne.VFR conditions
expected for Sunday with few clouds as high pressure builds in.

Another round of rain showers and flight restrictions lower
cigs are possible by Monday and possibly lasting through mon
night Tue morning with low stratus. ExpectVFR warm ssw flow to
prevail Tue after the early am clouds scour out. A cold front
approaches from the NW on Wednesday but expectVFR conditions to
prevail.

Marine
Latest sfc analysis shows high pressure off the new england coast
with weak low pressure off the carolina coast. Seas remain close to
5 ft over far southern coastal wtrs this aftn, but with a slight
downward trend expected and this being quite marginal will not hoist
any headlines. The aforementioned low slides NE along the coast
tonight and strengthens. A brief period of SCA criteria winds is
psbl over the wtrs, but with this expected to last less than a few
hours, will maintain previous thinking that a mws or smw will likely
be best suited to handle this. Pressure gradient then slackens into
sun, with sub-sca conditions expected to continue through at least
the middle of next week. Nne winds late Sun veer around to the ese
sun night as a surface high slides offshore, becoming southerly mon
night into Tue as a warm front lifts north across the waters. Ssw
flow persists into midweek, with seas remaining 2-4 ft.

Climate
Another round of record highs will possibly be challenged tue

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.
