NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
402 am EDT Wednesday Aug 20 2014 


Synopsis... 
a warm front slowly pulls north into the area today...then remains 
nearly stationary across the area into the upcoming weekend. 


&& 


Near term /until 6 PM this evening/... 
weak surface low pressure offshore continues to slowly move east and away from the 
mdatlc CST today. Lingering frontal boundary S of the forecast area this morning...W/ 
surface hi pressure to the north-northeast...resulting in continued surface flow from the east-northeast 
across the forecast area (in the wake of departing surface low pres). Remnant boundary 
to the S pulls slowly north into the forecast area today as weak surface low pressure in vicinity of 
lakes/upper Ohio Valley approaches from the west-northwest. Isolated/scattered convection along 
weak cold front and associated west/ middle/upper level short wave moving through eastern Ohio 
Valley at this time. During today...patchy fog to start...though right now not 
enough to include in forecast...then expecting vrb clouds to pcldy weather across 
forecast area. May be an isolated rain showers in vicinity of coastal southeast Virginia/NE NC this morning...and 
possibly far west-northwest areas in forecast area. Otherwise...from midday through afternoon/evening 
hours...scattered convection possible...especially northern portion of forecast area...as system passes 
by just to the north of the forecast area. Hi temperatures from the l/m80s at the CST...to 
M/u80s inland. 


&& 


Short term /6 PM this evening through Friday/... 
the overall pattern is agreed upon in the Middle Range part of the 
forecast as the upper low over the Great Lakes slides into the 
east and the upper ridge over the MS valley builds 
northward...setting up northwest flow aloft over of the middle Atlantic 
region. However...beyond the that...the timing of individual waves 
and the potential for convective complexes makes the timing of 
precipitation very uncertain for Thursday and Friday. At the 
surface...a weak frontal boundary that will be in the vicinity should 
be some stationary and nearly parallel to the flow aloft and could 
also be a focus for convection. At this point...with the 
uncertainty...will continue to lean more toward climatology with best 
chances in the Piedmont early in the afternoon and then area wide 
in late afternoon through about midnight. 


Low temperatures tonight from the m60s to around 70f. Hi temperatures Thursday from the m80s at 
the CST to l90s inland. Hi temperatures Friday in the l/m80s. 


&& 


Long term /Friday night through Tuesday/... 
unsettled weather pattern continues into the extended period in northwesterly 
flow aloft...but drier conditions expected by early next week. Temperatures 
will be slightly below seasonable...late Summer norms to begin the 
extended before returning to near normal early next week. 


Upper level flow during the extended is highlighted by split/blocky 
flow off the eastern Canada and northestern US coast and amplifying high 
pressure over the southern Continental U.S.. this places the middle-Atlantic region in 
northwesterly flow aloft. Associated back door front will push south of the 
local area Saturday morning. Surface high pressure prognosticated over the NE 
will ridge southwestward along the coast and into central Virginia. Northerly low-level 
flow indicated in medium range guidance will drive dewpoints 
downward into the middle 60s. However...model derived precipitable waters  remain 
around 1.8 to 2.0 inches. Combined with perturbations in the northwesterly 
flow...will have mainly cloudy weather and maintain chance probability of precipitation for 
diurnally driven showers/thunderstorms. Will also need to watch 
for possible mesoscale convective system development upstream...rounding the ridge and 
dropping into the region overnight through the weekend. By early next 
week the ridge axis will begin to build into the region as surface 
high pressure is prognosticated to locate off the coast. Block will 
remain off the NE coast...but moisture feed will be cut off. 
Decreasing moisture and increasing subsidence will likely result 
in dry conditions. However...confidence is not high at this time...so will 
leave probability of precipitation silent. 


North of the boundary...thicknesses and guidance yield temperatures in the 
low to middle 80s through Monday (around -1 Standard dev). Overnight lows 
generally in the upper 60s to low 70s near the water. Warming back 
up to near seasonable norms toward the middle of next week. 


&& 


Aviation /08z Wednesday through Sunday/... 
high pressure briefly builds over the area from the north behind 
departing low pressure system. Upper level short waves in a west/northwest 
flow will keep conditions unsettled for the next several days. Moist 
ground and low level conditions will maintain the chance for issues 
with ceiling/visibility each morning. 


As of 06z...NE winds prevailed at the taf sites with no precipitation 
expected early this morning. Sky conditions will be variable with 
gradual lowering of ceilings and visibilities. The main limitation is 
indicated to be ceilings but visibilities are not off The Table. Used the 
results of the previous overnight as a partial guide and a mix of 
MOS guidance to make a plan for the current taf. Despite ecg 
having the closest T/dew point spread...experience would indicate they 
may not go down to IFR for a while (i.E. Around 12z) and may have 
no lower than MVFR. Have ric/phf with some periods of IFR. Sby MOS 
is biased by temperatures that are too low. Kept orf out of IFR 
due to climatology. 


Conditions should be VFR by around 14-15z. Later today...there 
will be a chance for late afternoon/evening thunderstorms...especially north 
portions. Winds veer toward E/se. 


Outlook...chance for afternoon thunderstorms Thursday through Saturday. Some 
MVFR/IFR possible near sunrise each morning. Current forecast is dry on 
Sunday. 


&& 


Marine... 
no headlines necessary with this forecast package. Hi pressure persists just north 
of the area today as low pressure and an associated frntal boundary slowly 
slide southeast of the waters. The result will be NE flow mainly 5-10 knots over 
the Bay/sound/rivers and 10-15 knots over coastal waters. Expect 2-3 feet seas 
over the ocean and 1-2 feet waves over the Bay for today into tonight. 
Sub-Small Craft Advisory conditions continue as the aforementioned boundary lifts north as a 
warm front Thursday into Friday...then slides offshore over the weekend. 
During the weekend...the pressure gradient tightens with northeasterly winds 
increasing to 10-20 knots. This will push seas in the northern waters to 3-4 
feet...with 5 feet possible 20nm out.

Virginia...none.
