Synopsis
Weak high pressure moves off the coast today. A cold front will
move into the area this weekend and stall. This front will move
south of the area early next week.

Near term until 6 pm this evening
As of 3 am Thursday... Surface high pressure slides off the mid-
atlantic coast today while shortwave ridging builds aloft. Calm
winds with a moist boundary layer will bring areas of fog again
early this morning which is expected to burn off by mid
morning. A moist and unstable airmass continues across the
region but forcing will be limited and expect mainly isolated to
perhaps scattered showers and thunderstorms this afternoon,
generally west of highway 17. Highs expected around 90 inland to
mid 80s along the coast.

Short term 6 pm this evening through 6 am Friday
As of 320 am Thursday... Inland showers expected to diminish
during the evening with loss of heating but the upper ridge
pushes east after midnight with shortwave energy approaching
from the west and could see a few showers moving into the
coastal plain after midnight and may also see a few showers off
the water pushing into southern coastal sections. Patchy fog
possible late but light winds and increasing cloud coverage
expected to keep the fog pretty light. Lows expected in the mid
70s.

Long term Friday through Wednesday
As of 3 am Thursday... A more unsettled pattern is expected
Friday and Saturday, before slightly drier air takes hold Sunday
into early next week. An approaching mid-level trough will lead
to better rain chances by the middle of next week.

Friday through Saturday... A northward moving frontal trough
Friday will lead to an increase in low-level moisture and
instability and higher coverage of showers and thunderstorms,
especially during the afternoon and evening hours Friday and
Saturday. Instability will be especially high for Friday with
forecast CAPE values in excess of 3000 j kg and LI values in the
range of -8 to -10 during peak heating. Will have high chance
pops Friday and Saturday. A decent mid-level shortwave may also
keep storms going over the northern tier Friday night and will
have high chance pops north and slight chance south overnight
Friday night. Temperatures will also be quite warm Friday with
the SW winds, reaching the lower 90s over all but the immediate
coast. Temperatures may be a degree or two cooler for Saturday,
but still warm and very humid.

Sunday through Tuesday... Somewhat drier conditions are expected
Sunday into Tuesday as a mid-level ridge expands across the
area leading to hot temperatures and less convection as
precipitable water values drop to 1.5 inches or less for a
couple of days. There may be a few storms along the sea breeze,
but pops will be below climo through this period.

Wednesday... Upper ridge retrogrades to the west as a
strengthening mid-level trough dives south across the eastern
portion of the country. This will lead to better chances of
showers and thunderstorms for Wednesday into the latter part of
next week.

Aviation 07z Thursday through Monday
Short term through tonight ...

as of 2 am Thursday... Calm winds and a moist boundary layer will
bring areas of fog again this morning with lifr conditions
expected at the TAF sites. The fog is expected to dissipate by
mid-morning with predVFR conditions returning. Isolated to
scattered showers and thunderstorms possible this afternoon,
mainly west of highway 17. Light southerly winds and increasing
clouds with an approaching system expected to limit fog
development tonight but could see patchy light fog late
bringing mainly MVFR vsbys. Could also see a few showers move
into the region after midnight.

Long term Friday through Monday ...

as of 310 am Thursday...VFR conditions will prevail for much of
the extended period. However, occasional MVFR ceilings and vsbys
may occur in scattered convection Friday and Saturday with some
locally heavy downpours and gusty winds probable. A somewhat
drier pattern will lead to much smaller chances of precipitation
Sunday and Monday. Some early morning fog and patchy stratus
may also be possible in areas that receive decent rainfall
through the period.

Marine
Short term through tonight ...

as of 330 am Thursday... Weak high pressure moves off the mid-
atlantic coast today allowing light northerly flow below 10
knots to veer to south through the afternoon. Southerly flow
around 5-15 kt expected tonight with slight tightening of
gradients as a system approaches from the west. Seas will remain
around 2-3 ft through the period.

Long term Friday through Monday ...

as of 315 am Thursday... A fairly quiet marine forecast through
the extended period. High pressure offshore will lead to several
days of SW winds at 15 knots or less. Seas will generally run
2-4 feet through the extended period.

Mhx watches warnings advisories
Nc... None.

Marine... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
