Synopsis
Surface high pressure remains centered over the region this
afternoon and slowly drifts east, becoming anchored along or
just off the carolina coast over the weekend. A weak cold front
will push across the area Monday and Monday night.

Near term until 6 pm this evening
As of 1120 am edt Friday...

temperatures have moderated nicely this morning from early
morning lows in the 40s-l50s (in many areas). Sfc hi pres will
be slow to move just off the coast by late this afternoon early
evening. Pleasant wx W plenty of sunshine and light vrb winds
becoming ssw (remaining blo 10 mph). May only very minor
adjustments to present fcst. Highs from the m-u70s along the
coast to the u70s around 80f well inland (warmest from the
piedmont to metro ric).

Short term 6 pm this evening through Sunday night
As of 330 am edt Friday...

clear tonight not quite as cool with lows mostly in
the 50s though a few upper 40s could occur over interior
southern va and interior NE nc directly under the sfc high.

The sfc high more or less remains in place or shifts just
slightly off the coast of nc on Saturday. Continued mainly sunny
and dry for Sat with temperatures moderating a few more degrees
(to slightly above avg) with highs into the mid 80s well inland
and upper 70s around 80f at the coast. Clear Sat night Sun am
with lows in the upper 50s to mid 60s. Turning a bit warmer
Sunday with increasing southerly flow should see highs into the
upper 80s to near 90f well inland with low to mid 80s near the
coast.

Long term Monday through Thursday
As of 330 am edt Friday...

medium range period characterized by very warm temperatures on
Monday in ssw low level flow ahead of a weakening cold front.

Highs will be mostly in the mid 80s to around 90f. After that,
models have trended a little stronger with upper troughing
diving ese from central canada into new england Mon night
through tue. This will allow for somewhat cooler temperatures
tue into Wed (though still near of slightly above avg). Ridging
aloft over the southeast us will slowly re-amplify over the
region wed-thu, with temperatures gradually warming a few
degrees by thu.

Rain chances remain essentially nil through the first half of
the period, and don't go much higher even with the next front
early next week. Aforementioned upper ridge holds strong over
the southeast, and keeps moisture from next (weak) front... And
any remnant moisture from TC imelda... Well north of the local
area late Monday and Tuesday. Pops are no better than slight
chance over far northern CWA Mon night and tue... And silent
(<14%) central and south through the period.

Aviation 14z Friday through Tuesday
As of 710 am edt Friday...

vfr conditions through the period under mainly clear skies.

Winds today will be much lighter for coastal areas compared to
the past few days. Generally expect a light SW flow today
(locally onshore NE at korf), with wind speeds 5-10kt or less.

Outlook: high pressure remains in control through the weekend. A
cold front crosses the region late Monday or early Tuesday with
little to no precipitation expected. High pressure then builds
in behind the front on Tuesday.VFR conditions through this
period with winds generally 10kts or less.

Marine
As of 355 am edt Friday...

early morning surface analysis shows ~1027 mb high pressure
centered just nnw of the waters. This has resulted in
light variable winds across areas N of CAPE charles, with 5-10
kt northeast winds over the SRN coastal waters currituck sound.

However, seas are still 6-7 ft N 7-9 ft S of the va-nc border
(due to swell from departing post-tropical cyclone humberto).

Waves are 1-2 ft on most of the ches bay with 3-5 ft waves over
the mouth of the bay (again... Due to swell from humberto). The
high settles over the waters today before becoming centered just
to our S by late tonight. This will allow light variable winds
today to become SW around 10 kt tonight. Seas (and waves in the
mouth of the bay) will be very slow to subside. The SCA has been
extended through 1 pm for the mouth of the bay, while scas
remain in effect for all ocean zones through 12z sat. While nwps
guidance suggests that waves remain AOA 4 ft in the mouth of
the bay through a good part of the day on Saturday, not
confident enough to extend the SCA farther ATTM (as wavewatch is
forecasting seas at CAPE henry to drop to 5 ft by midday
today).

The high is expected to migrate offshore this weekend. Winds will
mainly be s-sw AOB 12 kt from Sat through Sun am. Seas should fall
below SCA criteria by Sat evening (at the latest) over the ocean
before falling to 2-3 ft by late Sun am. A slight uptick in s-sw
winds (and seas) is expected by Sun evening (increasing to 15 kt
over the bay 15-18 kt over the ocean... Highest n). Winds diminish to
10-15 kt on Mon as a weak cold front then approaches the region
before crossing the area from Mon night-tue am. The current forecast
has winds seas remaining just under SCA criteria from Sun evening-
sun night, with sub-sca conditions expected with the fropa.

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.
