Synopsis
Above normal temperatures will prevail much of the upcoming
week as high pressure offshore brings southerly winds. A series
of low pressure systems will bring a chance of rain Monday into
Tuesday, and again late next week. A cooling trend is expected
into next weekend.

Near term /through Monday/
As of 230 pm Sunday... Once again, a warm southerly flow has allowed
temperatures to rise in the mid and even upper 70s most places with
60s at the beaches. A diurnal CU field has formed, not as extensive
as yesterday, as ample low level moisture advection continues off of
the ocean. A few very light returns have appeared on radar but no
ground truth of any precip actually touching the ground yet.

Considering the very dry air aloft and lack of triggers, will be
keeping pops today below mentionable levels.

For tonight a light southerly flow will continue with high pressure
dominating the western atlantic. Lows will be in the mid 50s for
most locations.

Model soundings suggest another partly cloudy yet dry day as the
moist southerly low level flow continues around the western atlantic
ridge. Temperatures will remain above normal with highs in the mid
to upper 70s most places. A few places will hit 80.

Short term /Monday night through Tuesday night/
As of 230 pm Sunday... Another in a series of dampening shortwaves
will move across the tennessee valley and mid atlantic region
through the period with a a cold front trailing at the surface.

We continue to advertise low chance pops for the daytime hours
Tuesday with slight chance either side of this to address any
timing issues. The front will cross the area in the early
morning hours of Wednesday. Thermal profiles look slightly
warmer than recent days with the southwest flow ahead of the
system. Depending on the amount of sunshine Tuesday, there could
be widespread 80s. Overnight lows remain entrenched in the 50s.

Long term /Wednesday through Sunday/
As of 230 pm Sunday...

Aviation /19z Sunday through Friday/
As of 18z... High confidenceVFR for the next 12 hours of the taf
valid period for all sites. Moderate confidence ifr in fog
around and just before daybreak for our inland sites of lbt and
flo.

Extended outlook... Flight category restrictions are possible in a
few bouts of showers and thunderstorms late Mon through Tue and
again thurs night. ExpectVFR conditions after cold front moves
through on Wed lasting into thurs.

Marine
Near term /through Monday/...

as of 230 pm Sunday... A light south to south-easterly flow of
around 10 kts will continue through the near term as high
pressure continues its hold over the western atlantic. Winds
near shore this afternoon and Monday afternoon will be a little
bit higher, in the 10 to 15 kt range, and gustier as the
afternoon sea-breeze circulation sets up. Seas will remain right
around the 3 ft range through the period.

Short term /Monday night through Tuesday night/...

as of 230 pm Sunday... Very light winds from the south, southeast
initially will become better defined through the day Tuesday as a
cold front approaches from the west. Not the most overpowering flow
however as speeds increase to 15-20 knots briefly before backing off
Tuesday evening as the front loses some of its identity. Significant
seas will increase from initial 2-4 foot values to 3-5 feet Tuesday
afternoon and evening with the increase in winds.

Long term /Wednesday through Friday/...

as of 4 am Sunday... Light winds Wednesday in wake of a cold
front can be expected, followed by a wind-shift to the n_ne
Wednesday night as a back door cold front pushes across the 0-20
nm waters. Briefly this intrusion will transition to light wind
as the high moves overhead Thursday afternoon. A strong and
progressive southern system will bring increasing se-s winds
late Thursday and an advisory may very well be needed for 25 kt
gusts late Thursday night ahead of its cold front. Strong storms
and numerous showers appear likely on the water Friday.

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.
