NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
412 am EDT Tuesday Sep 2 2014 


Synopsis... 
high pressure builds over the southeastern states today. A weak 
front drops into the area tonight and settles near the Virginia 
North Carolina border Wednesday. High pressure returns Wednesday 
night and Thursday. 


&& 


Near term /until 6 PM this evening/... 
per latest water vapor imagery...high pressure remains over the 
southern Continental U.S. With ridging over the western Atlantic. At the surface...high 
pressure remains over the western Atlantic into the southeast states with a 
weak surface trough over eastern Virginia. A shortwave trough over the upper 
Midwest is producing a broad area of showers/thunderstorms from 
the lower MO valley into the Ohio Valley. This shortwave and an 
associated cold front will approach the local area today. 
Meanwhile...latest regional radar mosaic depicts echo free local 
area with only a few showers lingering well offshore. Dry 
conditions will prevail through the morning with mild morning temperatures. 


For today...shortwave will Delaware-amplify and lift into the NE states 
as the weak cold front reaches the central Appalachians late. Warm air advection in 
SW low level flow will push 850 mb temperatures to around 20c (~+1 Standard dev). 
Combined with deep mixing and SW wind of 10-15 miles per hour...high temperatures 
expected to warm into the middle-upper 90s inland with low 90s along 
the coastlines. Afternoon dewpoints forecast to mix back into the 
middle 60s...which should once again serve to keep heat indices at or below 
100. Forecast highs average around +1.5 to +2 St dev above seasonal 
means...and approach but fall just short of records (please see 
climate section below). Model soundings show much of the area to 
be well-capped above cumulus bases...and thus have kept a silent pop 
through much of the day. The exception is over NE NC along 
possible sea breeze. The best chances for precipitation (albeit low-end 
chance) hold off until the short term as the front drops through the 
region. 


&& 


Short term /6 PM this evening through Thursday/... 
cold front drops into the region tonight as a weak wave pushes 
over the central Appalachians. Warm/moist and marginally unstable 
airmass in place in advance of the weakening front will result in 
only isolated to widely scattered showers/thunderstorms. While 
precipitable waters  prognosticated around 1.8 inches...lack of upper level 
support/forcing for ascent and westerly flow will limit overall 
coverage. Front washes out over the area/just south of the area 
Wednesday as westerly flow aloft prevails. Surface high pressure builds over the 
region Wednesday as weak surface trough remains over the southeastern portion of 
the local area. Given continued warm/moist and marginally unstable 
air mass...will maintain slight chance-low end chance probability of precipitation Wednesday 
and Thursday...centered mainly along the trough axis and Theta-E 
ridge over the southern local area. 


Highs remain nearly +1 Standard dev through the short term...generally 
around 90 degree inland and slightly cooler along the immediate 
coast. Mild overnight lows generally in the upper 60s to lower 
70s. 


&& 


Long term /Thursday night through Monday/... 
long term period will start off with above normal temperatures and 
occasional chances for rain. For Thursday ngt/Fri...surface hi pressure centers 
offshore with a broad upper-level ridge across the eastern Continental U.S.. did 
include a slight chance-chance for a rain showers/thunderstorm (especially over western 
areas) closest to the greatest moisture axis and surface Lee trough...but 
nothing widespread expected. Temperatures Friday will rise into the upper 80s to 
lower 90s under a mostly/partly sky and light southerly winds. 


For the remainder of the period...cold front approaches from the west 
as an upper-level trough digs across the eastern Continental U.S.. chances for rain 
will increase into the weekend as the front drops into the middle 
Atlantic. Tough to exactly time the precipitation this far out in 
time...but for now will go with a 30-40% chance for rain showers/thunderstorms both 
Sat and sun. Hi temperatures ahead of the front Sat will be near 
90...dropping into the low to middle 80s on sun with increased cloud 
cover and the front in the vicinity. 


&& 


Aviation /08z Tuesday through Saturday/... 
VFR conditions prevail early this morning through today in warm SW 
flow. SW winds will average around 10 knots this aftn/evening...and will 
slowly shift to the northwest overnight into Wednesday morning. Could see 
isolated showers/thunderstorms late this afternoon...but expect the greatest chance 
will be from 00-06z/Wednesday as the front pushes into the region. 
Coverage will tend to be scattered so still too much uncertainty 
to include rain showers or thunderstorms and rain in tafs at this point. 


Mainly dry/VFR conditions Wednesday-Friday as surface front washes out across 
NC...although an isolated late afternoon/evening shower or thunderstorm still 
possible for far southern Virginia/NE NC. Does appear to be a higher 
probability for showers/thunderstorms and reduced visibilities and ceilings by Sat as 
next front moves into the area and stalls. 


&& 


Marine... 
conditions look to remain sub-Small Craft Advisory through the next several 
days...S/SW flow averages 10-15 knots or less today as surface high stays anchored 
over the western Atlantic with a weak trough over the interior. 1-2 feet 
waves over the Bay and 2-3 feet seas over coastal waters for the most part. 
A frontal boundary drops into the area and weakens later tonight/early 
Wednesday. While there will probably be an hour or two of increased winds 
as they shift to the north/northwest as the front passes...not anticipating 
any headlines. This due to an overall lack of cold air in the wake 
of the front. Pressure gradient is rather weak as well as surface high 
pressure builds to the north of the area on Wednesday. Winds shift from 
north/northwest Wednesday morning to the east/southeast late Wednesday afternoon/Wednesday night. Winds generally 
should be east-southeast to S Thursday into Friday at 10-15 knots or less...eventually 
shifting to the south-southwest Friday night/Sat as next cold front approaches.
