915 pm edt Mon jun 26 2017
A weak cold front will cross the area tonight into Tuesday
morning. A secondary boundary will push across the region late
Tuesday into Tuesday night. Surface high pressure will build
over the area Wednesday, then slides off the coast for Wednesday
night and Thursday.
Near term until 6 am Tuesday morning
Clouds associated with a weak trof now pushing to the coast with
additional clouds to move into the area from the NW late ahead
of the approaching cold front. Thus, text products to avg out
partly cloudy for the rest of tonight. Cooler with lows in the
upr 50s to lwr 60s.
Short term 6 am Tuesday morning through Thursday
Broad trough aloft slides fm the ERN great lakes oh valley ewrd
acrs the NE u.S. And mid atlc region Tue into Tue evening. A
relatively potent S W aloft will track acrs the local area tue
aftn into Tue evening. Despite relatively dry airmass, this
system could prove strong enough to squeeze out isolated to
sctd showers or tstms in the aftn into the evening, esply E of
i 95. Will carry 20-40% pops, with the highest pops over SE va
and NE nc. Highs in the upper 70s to lower 80s.
Sfc high pressure will finally build into over the region tue
night thru wed, providing dry weather and comfortable conditions
under a mainly clear sky. Lows Tue night in the lower to mid 50s
inland, to the upper 50s to lower 60s at the coast. Highs on wed
ranging fm the upper 70s to mid 80s.
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. Lows Wed night 60 to 65, and highs on
thu in the mid to upper 80s.
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 01z Tuesday through Saturday
Vfr conditions across the CWA with only a few scattered clouds
this evening. A weak cold front will pass through the region
overnight and Tuesday. Isolated or scattered
showers thunderstorms are possible Tuesday afternoon evening,
especially in the southeast portions of the cwa. Otherwise,VFR
conditions expected for much of the week, as surface high
pressure builds over the region then slides off the coast.
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 Tue morning and with pressure rises Wed morning as sfc high pressure
builds into the region from the nw. E winds will shift to the sse and increase
a bit this evening but only to 10-15 kt for a few hrs. Weak CAA on Tue 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.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
