NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
333 PM EDT Sat Jul 4 2015 


Synopsis... 
unsettled weather conditions will prevail through the Holiday 
weekend as a frontal boundary oscillates north and south across 
the region. The front finally lifts north of the area by Tuesday 
ahead of the next cold front that should move into the local area 
the middle of next week. 


&& 


Near term /until 6 PM this evening/... 
late morning analysis indicates surface low pressure centered just off 
the Atlantic coast of the Eastern Shore...with trailing surface boundary 
aligned west-east over northern portions of the forecast area. Another area 
of surface low pressure is centered across SW PA with a trailing cold 
front over WV and eastern Kentucky. West-southwest flow prevails aloft. Scattered 
showers still ongoing along the front over the Upper Bay and into 
Accomack Colorado Virginia and Maryland zones. Elsewhere...radar generally precipitation-free 
under mostly cloudy conds...with increasing amts of sunshine over 
far southern Virginia and NE NC. 


For the rest of today...have scaled back on probability of precipitation to go west/ a dry 
forecast through about 18-19z most areas (except will maintain 
low chance probability of precipitation north/NE close to the front) as region will be in between 
the 2 systems. After 18-19z...surface low in SW PA tracks east-northeast with 
trailing cold front pushing east of the mountains upper level shortwave 
will push across the region as well...and area will even be into 
some rrq forcing from 250-300 mb upper level jet. With surface 
heating/increasing instability...expect probability of precipitation to rapidly ramp back 
up to high chance central and southeast (40-50%) to likely (60%) N/NW. Will 
then gradually shift likely probability of precipitation into eastern/southeast Virginia after 20-21z. 
Storm Prediction Center/rap mesoanalysis shows ~30kt of effective shear into southern /se 
Virginia by late afternoon...so some gusty winds possible with storms (more 
likely if enough sunshine can prevail through middle aftn). 
Still...the main concern later this afternoon/evening will continue to 
be from potential additional areas of of MDT/heavy rain (especially over 
southern Virginia/NE NC where some of these areas received 1-3 inches/locally 
higher amts Friday eve). Depending on radar trends later today...may 
need to issue a flood/Flash Flood Watch west/ afternoon forecast through 
tonight for portions of the County Warning Area (mainly southern 1/2). Highs today 
range from upper 80s/around 90f far S/southeast with variably/partly 
sunny skies to the upper 70s/lower 80s north where skies average cloudy/mostly 
cloudy. 


&& 


Short term /6 PM this evening through Monday/... 
frontal boundary stalls in vicinity of Virginia/NC border tonight...then begins to move 
back north once again lt sun into Monday as low pressure surface-aloft lifts NE from 
the Gulf states to the central mountains there remain some model 
inconsistencies in this scenario...largely relating to timing and 
where axis of highest quantitative precipitation forecast takes place. 


Lingering rain showers/thunderstorms tonight far southern Virginia/NE NC while drying occurs 
over north-northeast portions of the forecast area (esp after mdngt). The favored area of 
additional rain showers/thunderstorms on sun likely to be from scntrl Virginia to far southeast 
Virginia/NE NC in vicinity of stalled frontal boundary. Mostly cloudy S...partly cloudy 
NE tonight through sun. Low temperatures from the M/u60s north to the u60s- l70s S. 
Hi temperatures sun mainly in the l/m80s. 


00z/06 NAM farther west west/ axis of significant precipitation Sun night into Monday as low 
pressure moves into the central mountains will have probability of precipitation gradually incrsg 
into central/interior eastern Virginia into Monday...while keeping probability of precipitation lower at 
much of the CST. Most low temperatures Sun night in the u60s-l70s. Vrb 
clouds-mostly cloudy Monday west/ hi temperatures in the l/m80s. 


At this time...total quantitative precipitation forecast through Monday expected to average 1-1.5 inches central/scntrl 
Virginia to interior NE NC...tapering to an average of about 1/2 inch over the 
lower Maryland Eastern Shore. However...lclly much higher amts are certainly possible 
due to hi precipitable waters  (1.75-2 inches)/slo moving or repeating 
shras/tstms. Will highlight ptntl in severe weather potential statement. 


&& 


Long term /Monday night through Saturday/... 
the medium range period is characterized by continued low amplitude 
upper troughing over the eastern conus, with gradual re-reemergence 
of the subtropical ridge over the southern tier of the Continental U.S. By the 
end of the week. Expect that with occasional upper 
disturbances/perturbations pushing across the northern middle-Atlantic, 
as weak surface trough persists in place overhead, mainly diurnally 
driven showers/storms can be expected. Have kept probability of precipitation in the chance 
range by day (near climatology norms), west/ slight chance or less overnight. 
Forecast precipitable water values will also remain high through the 
period...lingering around +2 S.D. Above normal. Accordingly, we'll 
need to be on guard for heavy rainfall with any showers through the 
period. Additionally, with this increased humidity/dewpoints through 
the period, continued to ride on the low end of guidance with 
forecast highs in the midweek period...generally favoring a typical 
middle-July warm/moderately humid set up across the area through much 
of next week. Look for daytime highs in the 80s to near 90 inland, 
with early morning lows 65 to around 70. 


&& 


Aviation /19z Saturday through Thursday/... 
showers and thunderstorms will continue to increase in coverage 
this afternoon and into tonight. Upper level energy along with surface 
boundary stretching east to west across central Virginia will phase over the 
area supporting the storm development. Heavy rain reducing visible and 
gusty winds(up to 3okt) will be the main impact of the storms. 
Rain chances will linger into Sunday as the boundary slowly moves 
south and waves of upper energy move over the area. MVFR ceilings 
are possible on Sunday for sites that get north/west of the front. 


Precipitation chances remain elevated into Monday as weather pattern 
remains unchanged. 




&& 


Marine... 
west-southwest gusts have been to 20-25 kts near the mouth of the ches Bay 
from around 0930z this morng...and will calm down to more like 15-20 
knots gusts by 13z. So...since this will only last about 3 hours...have 
not issued a Small Craft Advisory...and have winds at 15 knots for the forecast. 


No headlines in the short term today through Sun night. Unsettled weather 
conditions continue over the waters over the Holiday weekend. 
Frontal boundary was lifting north across the waters early this morng...and 
will lift just north of the area by around midday as low pressure moves north-northeast 
off the Delaware/Maryland CST. Winds will shift from the east-southeast over the lower Maryland and 
Virginia eastern shr...to the SW or west during this morng to around midday. The 
front will then drop back S of the area this eveng into sun 
morng...as surface low tracks NE out to sea. Waves average 1-2 feet...seas 
2-3 feet. 


&& 


Akq watches/warnings/advisories...
