Synopsis
High pressure builds into the region today into Monday, then
slides off the coast Monday night and Tuesday. The next cold
front will impact the region on Wednesday.

Near term through tonight
Latest analysis indicating a weak frontal boundary nearly
stationary along the nc coast, stretching back wsw into south
central nc. Weak sfc high pressure is centered along the
central southern appalachians. Aloft, a trough axis is pushing
east towards the coast and taking the associated shortwave
energy with it. Had a few showers tstms earlier acrs dorchester
county md, but this has since dissipated and skies are now
mostly clear. Patchy fog has developed, mainly over southern va,
but has genly not been dense thus far. For early this morning,
will maintain mention of fog in the forecast through 12-13z over
interior southern va NE nc, otherwise quiet conditions with
cooler temperatures than past several nights (readings in the
60s over much of the interior).

Skies become sunny after any early fog with some scattered
clouds this aftn. Overall, with sfc high pressure in place, pops
will be kept silent today (14% or less). Seasonably warm with
highs mainly in the mid-upper 80s at the coast to the upper
80s lower 90s inland. Humidity will be moderate with aftn dew
pts in the 65-70 f range most areas (lower 70s SE coast). Mostly
clear tonight, with lows in the upper 60s to lower 70s, patchy
fog possible again after midnight.

Short term Monday through Wednesday
The area of high pressure slides off the coast on Monday and
the flow turns more to the S se, which will allow some
additional moisture to return to the area. The orographic lift
will allow some convection to form along the blue ridge and
appalachian mountains. Some of this convection could slide newd
off the higher terrain and impact portions of the piedmont
counties and the NRN neck ERN shore later on Monday afternoon
and evening so have continued the slight chance pops. But most
areas should be dry due to a lack of lift and little mid level
moisture. Temperatures should begin to climb with most areas
getting back up into the lower 90s (85-90 f at the coast).

Monday night into Tuesday will see mainly dry weather as well,
but the humidity will increase slightly as the southerly flow
strengthens. Lows during the overnight hours should be in the
low to mid 70s and the highs on Tuesday should be a little
warmer into the low 90s. The southeastern portion of the cwa
would have the best chance for an isolated shower as some
atlantic moisture lifts newd into NE nc and the va tidewater.

Cold front will move into the region from NW to SE late tue
night through wed. Enough lift and moisture convergence on wed
for at least high chc pops all zones, and have raised them to
likely (60%) Wed aftn evening over the south as the front looks
to slow down with a wave of low pressure then tracking along the
front. Highs Wed mid 80s N to lower 90s s.

Long term Wednesday night through Saturday
A cold front exits the coast by Thu morning. Lingering
showers storms possible far SE va NE nc on thu, although they
should taper off from NW to SE as the front moves farther
southeast and away from the area. Otherwise, cool canadian high
pressure builds across the midwest into the ERN great lakes thu-
sat with dry conditions anticipated during this timeframe.

Highs thu-sat mainly upper 70s to lower 80s. Lows Wed night
mid- upper 60s NW to 70-74f se. Lows Thu Fri nights around 60f
nw to around 70f se.

Aviation 08z Sunday through Thursday
Earlier tstms acrs the md eastern shore diminished, with mainly
clear skies across the region. Seeing patchy MVFR ifr conditions
in fog over southern va, but thus far none of this is affecting
taf sites. Still think some MVFR fog will be possible from
09-12z (except at orf). All fog should quickly dissipate after
12z. After that...VFR conditions today through Monday as sfc
high pres builds back into the region. There will once again be
the potential for some patchy fog early on Monday morning. The
next cold front approaches the region late Tue and into wed.

Sub-vfr conditions and showers thunderstorms will be possible
wed, and may linger across the SE terminals into Thu morning.

Marine
No headlines in the short term today thru Mon night. High
pressure will build over the area today, then slides offshore
and out to sea late tonight thru tue. W winds 5 to 10 kt early
this morning, will become nne later this morning into this aftn,
then E by this evening. Waves 1 to 2 ft, and seas 2 ft. E or se
winds arnd 5 kt tonight, SE or S 5 to 10 kt mon, then S 5 to 10
kt Mon night. Increasing S and SW winds Tue aftn into Tue night,
as a cold front approaches fm the nw. Speeds could reach 15-20
kt bay ocean with seas building to 3-4 ft north and 2-3 ft
south; waves building to 2-3 ft. SCA flags may be possible for
the ches bay Tue night. The cold front will cross the area
during wed, and exit the coast by Thu morning. Winds n-ne aob
15 kt behind the front late Wed thru thu.

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.
