Synopsis
Low pressure will track northeast off the mid atlantic coast
this morning. The storm continues to track east northeast
farther out to sea this afternoon while high pressure builds in
from the west. High pressure sliding from the gulf coast states
eastward to off the southeast coast will bring dry weather and
moderating temperatures to the area Friday through Sunday.

Near term until 6 am this morning
Current WV imagery and 310k mont. Stream function depict a
potent upper low gradually pushing across va nc early this
morning. The 3 goes-16 WV channels each show the presence of a
trowal over ERN nc, with akq mhx radars showing some rather
impressive banding, although the past few scans show that some
dry air is beginning to entrain. Lightning has been observed
offshore on the WRN periphery of the surface low, with even some
flashes earlier into far ERN nc. Not much ground truth so far
for snowfall in NE nc near the albemarle sound and atlantic
coast, but 3hr dual- pol precip analysis depicts 0.3-0.6" of
liquid for these locations and 850-700mb thickness values ~1520m
would support about a 12:1 slr, so there could be 4-8" of snow
accumulation overnight. This is combined with a nnw wind of
20-30 mph with gusts to 40 mph. Snow will continue to taper off
through 7 am, but the winter storm warning will continue through
7 am to account for blowing and drifting of snow.

Otherwise, drier air is spreading over the remainder of the
area. Clearing has occurred across the WRN half of the area,
which has allowed temperatures to drop into the teens, and even
some upper single digits. Drier air will continue to overspread
the region this morning. Mid-level WAA resumes rather quickly by
this aftn. A cold start to the day is expected with
temperatures only rising into the mid upper 20s through 9-10 am.

Limited mixing combined with slowly melting snow should result
in rather stable lapse rates and and this will offset mid-level
waa with surface high temps only reaching the upper 30s to
around 40f.

Short term 6 am this morning through Saturday
High pressure will then slide from the gulf coast states
eastward to off the SE coast tonight through Saturday, and bring
dry weather, a clear sunny sky, and moderating temperatures to
the area. Lows tonight will mainly be in the low to mid 20s,
with some upper teens possible over the SW piedmont where a
thicker snowpack will be present. Highs Friday will mainly be in
the upper 40s to low 50s. Lows Friday night will range from the
mid 20 to around 30f. The airmass will continue to modify
Saturday with high temperatures ranging from the upper 50s to
perhaps around 60f well inland, with low to mid 50s for the ern
shore and coastal SE va NE nc.

Long term Saturday night through Wednesday
Milder spell of wx through the extended forecast pd. Pattern evolving
fits transition of mjo through phase 4 toward phase 5... Leading to
aoa normal temperatures. Other than a very wk upper level system
tracking off SE CONUS coast sun... Sfc hi pres and upper level

cold front approaching the mtns. That front will make progress
across the local area Mon night-early Tue W potential shras
(though 12z 17 ECMWF a tad slower than 12z 17 GFS attm).

Drying clearing out and a bit cooler (returning to near seasonal
levels) for Tue afternoon-wed.

Lows Sat night ranging through the 30s. Highs Sun in the l50s
on the ERN shore to 55-60f elsewhere. Lows Sun night mainly
35-40f. Highs Mon in the m50s on the ERN shore to the u50s-l60s
elsewhere. Lows Mon night in the u30s to l40s. Highs Tue in the
l50s on the ERN shore to the m-u50s elsewhere. Lows Tue night in
the l-m30s. Highs Wed in the u40s-l50s.

Aviation 09z Thursday through Monday
Drier air slowly filtering from the nw, with mainlyVFR
conditions at all sites but ecg, and ecg should improve through
12z. Wind will generally be N with gusts to 25 kt near the
coast early this morning. The sky gradually become sct to skc
through 12z, with breezy N to NW winds continuing.VFR mainly
clear for the remainder of the day with winds shifting to the w
by aftn.

Outlook: predominantVFR conditions Thursday night through
Sunday as the trough departs well to the NE and a ridge builds
across the region. Next chance for showers (rain) and flight
restrictions will arrive later Mon mon night.

Marine
Added the northern coastal waters to the gale warning which
runs through 7 am est. Continue to see gusts of 35 to 40 knots
over all coastal waters mouth of the bay this morning. A few
gusts to 35 knots will also be possible over the bay this
morning, particularly on the east side of the bay.

The surface low has moved off the coast and will continue to
push out to sea through the day. Strong CAA continues this
morning with gale and scas in effect for all waters. Seas are
also churned up this morning with seas of 6 to 10 feet over the
coastal waters (waves 3 to 5 feet). High pressure settles back
into the area today allowing for winds to quickly diminish
through the morning. High pressure will persist through the
weekend allowing for sub-sca conditions.

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.
