NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
757 PM EDT Friday Oct 31 2014 


Synopsis... 
weak high pressure will slowly dissipate across the region through 
tonight. A strong low pressure system will develop off the middle 
Atlantic coast Saturday and Saturday night before exiting the area 
on Sunday. High pressure returns for the beginning of next week. 


&& 


Near term /until 6 am Saturday morning/... 
the latest surface analysis shows weak high pressure over the 
Piedmont...with a 1005mb area of low pressure off the NC Outer 
Banks...which has formed in response to a shortwave trough pushing 
off the southeast coast. A stronger shortwave trough lags back over 
the southern Great Lakes and this will become the primary feature into 
Sat. The leading wave will continue to pull to the NE tonight...as 
the stronger wave continues to dig south-southeast across the lower Ohio Valley. 
Overall dry conditions are expected...with increasing middle/high 
clouds (once afternoon cumulus dissipate) as the local area remains in a 
region of subsidence between the two systems. 12z high-res data does 
indicate some moisture could back into the lower Maryland Eastern Shore late 
tonight seemingly related to a NE fetch associated with a cold 
conveyor belt. A high chance to low end-likely (50-60%) probability has 
been included late tonight to account for this. Temperatures should 
drop into the low/middle 40s late this evening...which should be the 
eventual overnight lows as temperatures become steady after midnight. 


&& 


Short term /6 am Saturday morning through Monday/... 
the overall forecast scenario remains similar. A strong shortwave 
trough will dig across the Tennessee Valley tonight and across the 
Carolinas Sat. Good agreement continues with respect to a closed 
upper low forming off the Carolina coast midday Sat...with surface 
cyclogenesis off the Outer Banks Sat afternoon/evening. The surface 
low will quickly lift to the NE later Sat night into Sunday...with 
~1032mb surface high pressure building in from the northwest through Sun 
night. The aforementioned area of subsidence should remain over the 
area (with the exception of the Eastern Shore and far SW piedmont) 
through midday Sat. The chance of rain then increases Sat afternoon 
across NE NC/southeast Virginia as the low develops off the coast. Overall quantitative precipitation forecast 
amounts will be minimal and generally less than 0.25in. The highest 
amounts (0.25-0.50in) should be across the Eastern Shore where the 
duration of rain should be longest. 


A period of strong north-northeast wind (25-35 miles per hour with gusts to ~45mph) is 
expected along coastal zones as the low deepens off the coast and 
strong cold air advection commences. Areas of minor tidal flooding are possible 
along the Atlantic beaches and lower ches Bay (see coastal flooding 
section below). A Wind Advisory may be needed over at least some of 
the coastal zones Sat night for a 6-10 hour period. This will remain 
highlighted in the severe weather potential statement at this time. 


Rain will taper off Sat night with subsidence in the wake of the 
departing wave. The sky clears out quickly into Sunday morning 
(although a band of SC could develop off the Bay Sunday due to the 
cooler drier air advecting over SSTs ~62-64f). The surface high of 
Canadian origin sinks from the Ohio Valley into the southeast 
beginning Sunday. This will usher in the coolest air of the season 
to date. Highs Sunday should range from around 50 N/NE...to the middle 
50s S. The first widespread freeze of the season should occur late 
Sun night/early Monday morning as lows drop to 28-32 over the interior 
coastal plain and Piedmont. Enough surface pressure gradient will likely 
linger closer to the coast...which will keep lows in the middle/upper 
30s. 


The high shifts offshore Monday...with south-southwest flow resuming across the 
region. Highs should rebound into the upper 50s/middle 60s under a 
mostly sunny sky. 


&& 


Long term /Monday night through Friday/... 
medium range period characterized by general moderation of 
temperatures to begin the period as high pressure slides off the 
southeast coast Tuesday/early Wednesday with resultant 
south-southwest flow allowing maxima to rebound into the 60s to 
lower 70s Tuesday and Wednesday, with early morning lows moderating 
back into the 40s to near 50 Wednesday and Thursday morning. 


Aloft, upper pattern will be characterized by upper ridging, which 
will gradually break down and slip offshore late Wed/Thu. Northern 
stream disturbance traversing the Canadian prairies into the upper 
Great Lakes during the midweek period, with the associated weak 
surface front dropping into the area by late Wednesday ngt/Thursday. Once 
again, the best forcing/dynamics look to remain confined to the 
north/northeast. Therefore, suspect the frontal passage will once again have 
little moisture with which to work. Will keep pop no higher than 20% 
for Wed/Thu...with only a slight drop off in temperature Post 
frontal late in the into the 60s, with early morning lows near climatology 
values Friday and Sat mornings. 


&& 


Aviation /00z Saturday through Wednesday/... 
the region is between systems as of 00z. Several waves of low 
pressure are sliding along a stalled front off the coast while a 
strong upper level disturbance continues to move southeastward through the 
Ohio Valley. Low pressure off the North Carolina coast will begin 
to develop overnight and into the day on Saturday. This will 
strengthen the onshore flow and clouds will develop and lower to 
MVFR/IFR levels toward sunrise Sat and continuing through the day. 
As the low strengthens...expect winds to increase to 10 to 15 kts 
by 12-15z...increasing to 20-25kt by 18z...with gusts to around 30 
knots along the coast. 


The low will pull away from the coast after 06z sun with VFR 
conditions by 10z...but gusty northwest winds will linger through the 
day on Sunday. High pressure nudges into the area Sunday night 
continuing VFR conditions. 


&& 


Marine... 
latest observation reflect north-NE winds this afternoon 10-15kt. Surface low 
pressure has developed along the stalled coastal front oriented 
offshore. Winds have increased to low end/marginal Small Craft Advisory criteria this 
afternoon and have raised a Small Craft Advisory over the Lower Bay and sound 
through early this evening. Winds should diminish for the middle 
evening hours into early Sat as system pushes farther NE away from 
the area and farther offshore...to a position off of the New England 
coast by late tonight. 


Winds will be ramping up again towards sunrise Sat morning, as low 
pressure develops rapidly near Hatteras. Winds/waves/seas increase 
as this low pressure strengthens off the NC CST Saturday in response to 
a very potent middle-level shortwave trough. Small Craft Advisory over northern coastal waters (added 
Parramore to Cape Charles Light to existing sca) remains in effect for 
Saturday before the Gale Warning GOES into effect Saturday night. A 
period of 5 feet seas is expected over this area, while conditions 
elsewhere over the Bay and lower James look to deteriorate quickly 
enough Sat afternoon to warrant going directly to the gale headline. 


&& 


Tides/coastal flooding... 
low pressure is expected to rapidly strengthen off the coast late 
Saturday afternoon into early Sunday morning. Strong north-northwest winds are 
likely to result in tidal departures on the order of 1-2 feet above 
normal Saturday night along the Atlantic coast and Lower Bay. 
Minor tidal flooding is expected for these locations as the surge 
appears to coincide with the high tide cycle Saturday night/early 
Sunday morning.
