NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
343 am EDT Wednesday Jul 23 2014 


Synopsis... 
surface high pressure will remain in place over the western 
Atlantic today. A cold front will approach from the northwest 
through tonight...then push across the region Thursday and 
Thursday night. High pressure will build over the area on Friday. 


&& 


Near term /through tonight/... 
latest weather analysis features ~1022mb surface Bermuda high pressure in 
place offshore of the southeast coast, with only a weak, wavy inverted 
trough lingering along and just inland of the southeast coastal plain. 
GOES WV imagery showing a weak impulse tracking NE along the 
trough over eastern NC, with kakq radar showing some light-moderate rain showers 
just offshore of the northern Outer Banks. Have retained a light chance 
pop early this morning in this area. 


Otherwise, with the trough washing out today, Bermuda high will 
become dominant weather feature today...with deep layered return flow 
advecting very warm/moist air into the region. Precipitable water values increase 
into the 1.75-2" range (highest se) today, which in tandem with 
highs in the u80s/low 90s should yield plenty of instability. 
However, once again, shear remains marginal at best (10-15 kt) 
and poor forcing for ascent is indicated for much of the day. 
Thus, disorganized pulse convection is the favored storm Mode for 
the day, with a developing (pre-frontal) Lee trough to the west and 
numerous boundaries southeast serving as subtle foci for isolated to widely 
scattered convection, mainly late this afternoon into the early evening. 
Otherwise, a partly sunny day is expected west/ highs into the low to 
middle 90s inland, 85-90 along the coast. Strong low level mixing and 
downslope flow should allow dewpoints to fall off a few degrees this 
aftn, so while heat indices around 100f are expected, drop in dew points 
should keep apparent temperatures below heat headline criteria. Weak 
shear/forcing should allow for a lull in probability of precipitation after sunset through 
early Thursday morning. 


Dampening upper trough and its associated surface cold front will 
drop from the upper Midwest (this morning) towards the region late 
tonight into early Thursday. Expect clouds to increase as the trough 
approaches, becoming overcast late across the north/northwest (partly cloudy 
se). As front sinks slowly south towards thea area late tonight, 
will probably see some spotty rain showers/isolated T develop to our 
northwest...potentially reaching northern County Warning Area by day break. 
Therefore went with a 30-40% pop across the north...20% farther 
south. Partly to mostly cloudy and muggy with early morning lows 
in the low to middle 70s. 


&& 


Short term /Thursday through Friday/... 


Surface cold front will be dropping southeast ac receiver station the County Warning Area Thursday 
morning...reaching the coastal plain by afternoon. Unfortunately for 
portions of the forecast area (namely central Virginia/Richmond metro) where precipitation 
deficits past month or so average a couple/few inches, model guidance 
continues to depict best forcing coincident with 60-70kt rrq of 
upper jet arriving by Thursday afternoon from central NC towards the 
Tidewater area. Therefore, have kept best pop/higher quantitative precipitation forecast across 
the southeast County Warning Area Thursday afternoon/evening, gradually spreading southeast as the cold front 
settles farther south into NE NC Thursday night/early Friday. As is typical 
for this time of year, front will then likely get hung up across 
far southeast County Warning Area lt Thursday and much of Friday. Otherwise, for bulk of 
forecast area...gradual drying from the northwest to southeast is indicated as surface hi pressure 
builds in from the Ohio Valley. Drop probability of precipitation off for most areas Thursday ngt, 
but did maintain 20-30% probability of precipitation along the stalled boundary across 
coastal NE NC through Friday afternoon. Otherwise clearing and becoming a 
bit drier late Thursday through Friday. 


For temps, look for highs in the M/u80s north...u80s to l90s S Thursday. 
Highs Friday in the M/u80s inland...l/m80s at the CST. 


&& 


Long term /Friday night through Tuesday/... 
stationary front remains over NC Friday night with high pressure 
over the local area. This will result in dry conditions. Front 
remains stationary over NC on Saturday before slowing lifting back 
north through Virginia Saturday night into Sunday morning. Will carry 
slight chance probability of precipitation across the far south Saturday for possibility of 
afternoon convection near the front. By Sunday...the front will align 
itself across northern Virginia and will be the focus for thunderstorm activity 
across the entire area due to increased moisture/instability. Will 
carry chance probability of precipitation into Monday as well as the front dissipates nearby. 
The models are in good agreement about bringing a cold front through 
the local area Monday night with dry/cooler air arriving next 
Tuesday/Wednesday. Highs Saturday in the 80s. Warmest Sunday/Monday 
with highs in the upper 80s to low 90s. Cooler again next Tuesday with 
highs in the 80s. Lows mainly in the 60s to low 70s. 


&& 


Aviation /06z Wednesday through Sunday/... 
a warm front near the coastal Virginia/NC border will keep lingering 
shower activity in the Albemarle Sound vicinity through at least 
23/0800z. Thereafter...an approaching cold front will cause the warm 
front to shift southeast and away from the area after daybreak. Fog 
may be problematic across southern Virginia/NE NC...in the vicinity of the warm 
front. Observations have shown variable visibilities of 1-5sm and 
ceilings fluctuating between 100-1000 feet above ground level. At this time...kecg and ksby 
should be most adversely impacted by fog with visibilities as low as 
1sm possible and ceilings below 500 feet above ground level. Any fog that develops should 
lift/dissipate by 23/1400z. 


Otherwise...early morning sunshine in a moist and warm environment 
will allow scattered-broken cumulus to develop by late morning/early afternoon. 
Pre-frontal thunderstorms are expected to form by middle to late afternoon 
today and all taf sites are anticipated to be impacted. The 
previously mentioned cold front moves into the region from the 
west by late this evening...bringing a more focused line of 
showers and thunderstorms to the region overnight tonight into 
Thursday. The front stalls along the NC coast by Friday morning. 
This will shunt precipitation chances over far southeast Virginia and NE NC through 
Friday...possibly into Saturday. Surface high pressure builds back 
into the region from the west-northwest on Friday and then slides off the middle 
Atlantic coast by Saturday...bringing a return to rain-free 
conditions during the weekend. 


Note: observations from ksby are not readily available due to a 
communications problem...technicians are aware of the issue. 
Current information may be obtained by calling into the ASOS site 
directly. In the meantime...amend not schedule will be appended to the 
ksby taf until further notice. 


&& 


Marine... 
a stationary front off the NC coast will dissipate heading into this 
evening and overnight. Meanwhile...more typical Bermuda high 
pressure takes control by Wednesday morning...and lasts until the 
next cold front passes over the waters on Thursday. East-southeast winds at or below 
10 knots currently will gradually veer to the SW tonight....then remain 
SW 10 to 15 knots into Thursday morning. Once the cold front passes on 
Thursday...winds will veer to the north-NE at or below 15 knots through Friday 
morning. Winds become S-SW again at or below 15 knots by this weekend. Small Craft Advisory 
conditions are not expected the next few days...and probably not 
through the weekend either. Stayed close to nwps depiction for 
significant wave heights through the weekend with seas 2-3 feet 
building to ~4 feet Wednesday night/early Thursday before subsiding as winds 
become north-NE Friday. Waves will remain 1 to 2 feet.
