Synopsis
A weak cold front will cross the today. High pressure will
build over the area Wednesday... Then slides off the coast for
Wednesday night and Thursday.

Near term until 6 pm this evening
Broad trough aloft slides from the eastern great lakes oh
valley E through the NE CONUS and mid atlantic region into
(early) this evening. A relatively potent S W aloft will track
across the local area this afternoon early evening. Despite
relatively dry airmass... This system could prove strong enough
to squeeze out isold-sct shras tstms... Mainly in the aftn early
evening... ESP E of I 95. Will carry 20-30% pops... W the
highest pops over SE va and NE nc. Highs in the u70s-l80s.

Short term 6 pm this evening through Thursday
Sfc hi pres will finally build into over the region tonight
through wed... Providing dry weather and comfortable conditions
under a mainly clear sky. Lows tonight in the l-m50s inland... To
the u50s to l60s at the coast. Highs on Wed ranging in the
l-m80s... Mainly 70s at the beaches.

The high will slide off the coast for Wed night and thu... Maintaining
dry wx. A little more humidity returns as ssw flow starts to
dominate again (dewpoints return to more climo normal levels (in
the 60s) by Thu afternoon). Lows Wed night in the u50s-l60s
inland... L-m60s at the coast. Highs Thu 85-90f... Except l80s at
the beaches.

Long term Thursday night through Monday
Long term period will begin mainly dry Thu night Fri as the
models remain in good agreement with the pattern of high
pressure at the sfc and aloft centered off the mid-atlc se
coast. Highs Fri look to warm into the upper 80s lower 90s with
dew pts increasing to the upper 60s lower 70s. An isolated late
day TSTM possible over the far W and for interior NE nc but have
genly kept pops <15%. A little better chance for rain arrives
sat aftn Sat night as somewhat deeper moisture develops along a
lee trough. Will cap pops at 20-30% in the aftn evening under
partly-mostly sunny skies as any more significant forcing stays
w of the mtns closer to an approaching cold front. Lows mainly
70-75 f with highs again primarily in the upper 80s to lower
90s. Sunday will see a further increase in pops to ~40% by
aftn evening as the cold front gets closer to the local area.

With this several days out will cap pops at 40% for now, but may
raise pops for this in future updates if the timing holds. Mon
will see the front slow or stall across mainly southern portions
of the area with ~40% pops S to 20-30% elsewhere. Lows upper
60s to lower 70s and highs 85-90 f.

Aviation 07z Tuesday through Saturday
Vfr conditions early today across the local area W only a sct-
bkn high based clouds. A weak cold front will pass through the
region today. Isold-sct shras tstms are possible... Mainly this
afternoon and especially E of I 95. Otherwise,VFR conditions
expected for much of the week... As sfc hi pres builds over the
region then slides off the coast.

Marine
Generally a quiet pattern through Wed night with a weak pressure
gradient, although there will be a few brief wind shifts w
weak frontal passages early this morning and with pressure rises
wed morning as sfc high pressure builds into the region from
the nw. Weak CAA today will only bring N NW winds behind the
front of 10-15 kt, diminishing by aftn to 5-10 kt. Sfc high
pressure returns for Wednesday aftn leading to an aftn sea
breeze 10 kt or less. Waves over the bay only 1-2 ft with seas
over the coastal waters 2-3 ft thru wed. High pressure slides
well off the coast Thursday Friday with return flow resulting in
increasing s-sw winds to 15-20 kt. Waves 2-3 ft on the bay and
seas possibly building to 4-5 ft north of parramore island
(genly more like 2-4 ft for southern coastal waters). A few sca
headlines may be needed late Thu thu night, but they will be
marginal events.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
