Synopsis
High pressure will slide offshore tonight and Monday. A cold front will move
through Tuesday. High pressure will build in from the northwest late next week
then pass offshore next weekend.

Near term until 6 pm this evening
As of 1210 pm Sunday... Fcst on track with mainly sunny skies
except for some high clouds skirting the imd central and srn
cst. Temps already lower 60s most inland spots and shld rise to
mid upr 60s this aftn with 50s beaches.

Short term 6 pm this evening through 6 am Monday
As of 350 am Sunday... With axis of surface ridge offshore, the
low level flow will become more southerly tonight. Temperatures
will moderate a few degrees with lows by Monday morning in the
upper 30s over most areas, with lower 40s outer banks. Winds
will remain light under clear skies except for some occasional
cirrus.

Long term Monday through Sunday
As of 4 am Sunday... Mild weather is expected through the
extended period. A cold front will bring a threat of showers and
perhaps an isolated thunderstorms on Tuesday. Otherwise dry
conditions are expected for the extended period.

Monday and Monday night... High pressure weakens across the area
as an upper low lifts from the central plains toward the great
lakes while the attendant cold front pushes from the miss river
valley early Monday to the appalachians by late Monday night.

Increasing southerly flow brings low level WAA and expect
increasing stcu across the region through the period. Some
models, ECMWF and NAM especially, suggest enough moisture to
bring a few light showers to the region, mainly southern section
Monday afternoon, spreading across most of the region Monday
night and have slight chance to low end chance pops. Temps
will be very mild with highs Monday in the mid 60s inland,
perhaps upper 60s southern sections, and around 60 along the
coast. Temps Monday night remain mild as southerly flow
continues to increase and expect lows in the low to mid 50s.

Tuesday... A robust frontal system approaches the region Tuesday
and is progged to push across the region Tuesday afternoon.

Models have trended slightly slower with the progression of the
front over the past several runs but the 00z 21 models are in
generally good agreement with the timing. It will be a high
shear low CAPE scenario with models indicating 0-6km bulk shear
up to around 70kt but very little CAPE per the gfs ECMWF while the
nam has a little higher CAPE values to around 500 j kg. Cannot
rule out an isolated storm bringing strong wind gusts but with
better forcing for ascent displaced to the north expect the
overall severe threat to be minimal at this time. Continued very
mild with highs in the upper 60s to around 70 inland but cooler
water temps will hold temps in the low to mid 60s along the
coast.

Tuesday night through Saturday..Broad upper troughing continues
across the eastern CONUS with high pressure across the southern
southern plains Wednesday building into the region through the
end of the work week. Upper ridging builds in Friday into
Saturday with high pressure sliding offshore by Saturday with
return flow bringing milder conditions to the region. Expect
dry conditions with mainly clear skies much of the period.

Temps will be near climatology with highs in the low mid 50s
and lows in the low mid 30s, warming to around 60 Saturday.

Coastal sections will be cooler with highs mainly in the
mid upper 40s and lows in the mid 30s to lower 40s.

Aviation 17z Sunday through Thursday
Short term through Monday ...

as of 1210 pm Sunday... MainlyVFR thru period however there is
a threat for some fog late tonight. High pres will drift slowly
e tonight but cont to influence the region with mclr skies.

Dewpts have risen signif past 24 hrs and expect overnight temps
to drop to dewpts late. With calm winds could SE some patchy fog
develop after 06z. Given guidance not indicating much will just
show high end MVFR for now. Fog that develops will burn off mon
morn withVFR thru mid aftn. Late Mon could see some MVFR cigs
start to spread N over SRN tier as moisture increases on
backside of high pres.

Long term Monday night through Thursday ...

as of 430 am Sunday... Periods of MVFR CIGS and an isolated
shower Monday night. A strong frontal system pushes across the
region Tuesday with a period of sub-vfr conditions and gusty
southerly winds expected across rtes. Pred-vfr expected Tuesday
night through Thursday as high pressure builds toward the
region.

Marine
Short term today and tonight ...

as of 1210 pm Sunday... Winds cont to diminish and expect light
winds and 1 to 3 foot seas rest of the day with high pres over
the region.

Prev disc... Minimal changes needed to the current
marine forecast. Good boating conditions for late january
expected today and tonight as the axis of the high pressure
ridge moves from west to east across our region. Winds will be
westerly at 5-15 knots, although some gusts to 20 knots are
possible early this morning off the central waters. By this
afternoon and tonight, expect winds to gradually become more
e SE at 5-10 knots. Seas will be around 2 feet today, except 3-5
feet over the central waters early today. Seas will be 2-3 feet
in all areas for tonight.

Long term Monday through Thursday ...

as of 430 am Sunday... Good boating conditions continue Monday
with winds around 10 kt or less, gradually trending to S se
through the day and seas around 1-2 ft. Sly flow increases
Monday night and Tuesday ahead of strong frontal system and
expect ssw winds increasing to around 20-30 kt with gale force
gusts possible by Tuesday morning and seas peaking around 6-11
ft Tuesday afternoon. The front pushes across the waters late
Tuesday with winds becoming W NW around 10-20 kt Tuesday night
and early Wednesday with seas subsiding to 3-5 ft Wednesday
morning. Winds diminish 5-15 kt Wednesday afternoon but a mid
level disturbance moves across the region Wednesday night that
will serve to increase wind back to 10-20 kt into Thursday
morning before becoming N around 5-15 kt Thursday afternoon.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
