area forecast discussion
national weather service wakefield va
1009 am edt Thu oct 17 2019

Synopsis
Strong low pressure over new england will produce gusty west or
northwest winds across the area today. High pressure builds
into and over the region for tonight into Saturday resulting in
cool and dry weather. A disturbance in the gulf may bring
showers to the area late in the weekend.

Near term through tonight
As of 1000 am edt Thursday...

strong low pressure over new england and high pressure building
in from the west resulting in a tight pressure gradient across
the area. W NW winds will gust to 30-40 mph near the coast in
md and va and 15-30 mph inland piedmont this aftn into early
this evening. Some gusts up to 45 mph will be possible over the
lwr md ERN shore and into accomack co va) where a wind advisory
is in effect until 8 pm this evening. Otherwise, partly to
mostly sunny this aftn with high temps in the lower to mid 60s.

Short term Friday through Saturday night
As of 400 am edt Thursday...

the pressure gradient will relax tonight into Friday morning,
and winds should subside to 5-10mph by 12z Friday. High pressure
centered over the ohio valley will remain in control for Friday
and Saturday. Temps will remain cool with high temps in the
60s, and low temps ranging from the upper 30s to mid 40s along
the coast. A few locations across the western portions of the
area may drop into the mid 30s Saturday morning. Winds will be
nearly calm and with clear skies expected, would not be
surprised to see some reports of frost Saturday morning.

Long term Sunday through Wednesday
As of 400 am edt Thursday...

our next chance for rain will likely come from a disturbance
currently in the western gulf. Models are in better agreement
that this system will ride up the southeast coast this weekend
and will be in our vicinity beginning late Saturday night into
Sunday morning and likely bring showers to our forecast area
during the day on Sunday. Both the latest runs of the GFS and
ecmwf have precip exiting the area by late Sunday and keeping
Monday dry. Lowered pops for Monday but did not completely
remove them as confidence that far out is still on the lower
side. Trended cooler with the temps on Sunday, as rainfall and
cloud cover should hold MAX temps into the 60s. Assuming precip
does exit the region by Sunday night, temps rebound to the low
to mid 70s on Monday ahead of an approaching cold front. The cold
front will cross the region on Tuesday bringing another round
of showers and then cooler and drier conditions for Wednesday.

Low temps on Wednesday will be in the upper 40s to lower 50s and
high temps on Wednesday will struggle to reach 70.

Aviation 14z Thursday through Monday
As of 630 am edt Thursday...

vfr conditions through the TAF period. Gusty W NW winds through
the period due to a tightening pressure gradient from a
strengthening low in the northeast and high pressure to the
west. Wind gusts will be 20-25kts throughout the day with gusts
to around 35kts at ksby. Winds will decrease to 10-15kts late
Thursday night into Friday morning as the pressure gradient
relaxes.

Vfr conditions through at least Saturday. A storm system
currently in the western gulf is forecast to make it's way up
the southeast coast this weekend... Bringing the threat of
showers to our area for Sunday.

Marine
As of 430 am edt Thursday...

strong W winds prevail across the waters as intense sfc low
pressure (~975mb) is moving NE along the new england coast while
sfc high pressure is building into the lower ms valley. Decided
to extend the gale warning in the northern bay through this
evening even though conditions have dropped a little below gale
thresholds for the moment. High res models suggest some deeper
mixing may bring a return of slightly higher winds this
aftn early evening as wind slowly veer from the W to the nw.

Gales remain in effect into early Fri am for the coastal water
n of CAPE charles light. SCA is in place elsewhere for winds
mainly 20-25kt with gusts to 30 kt. Seas are mainly 5-7 ft with
bay waves 3-5 ft. The current forecast has winds remaining aoa
sca thresholds for bay and coast through ~12-15z fri. Sub-sca
conditions return by late fri, as high pressure settles over the
waters. Latest gfs ECMWF models have trended into better
agreement with the approach of another low pressure system from
the ssw Sat night, pushing off the mid-atlantic coast on Sunday.

Did not go as high with waves seas winds as some of the model
guidance but did increase winds to 15-20 kt over much of the
area with seas building to 5-6 ft Sunday and waves to 3-4 ft at
the mouth of the bay. And late this weekend before exiting to
the NE early next week. Thus, another round of scas (starting by
Sunday) looks likely now for at least the coastal waters and
lower bay.

Tides coastal flooding
As of 430 am edt Thursday...

water levels at bishop's head and cambridge, md crested right
at major flood thresholds yesterday and have rapidly dropped off
given the strong W flow and ebb tide dominance that will
continue today tonight. No additional coastal flooding with
subsequent high tide cycles through sat. While the water levels
have dropped, they are not expected to get down so far that any
low water advisories would be needed.

Akq watches warnings advisories

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.
