NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
407 PM EDT Friday may 29 2015 


Synopsis... 
high pressure over the northeast states will gradually slide off 
the coast tonight into Saturday. A slow moving cold front will 
approach from the northwest late Sunday...and will settle over the 
middle Atlantic Monday afternoon into Monday night. 


&& 


Near term /until 6 am Saturday morning/... 
a shortwave trough is slowly pulling off the New England coast 
this afternoon...with a trailing weak cold front lagging back over 
the middle Atlantic. This has provided enough low-level convergence 
to support isolated-scattered convection over the Piedmont and isolated 
convection from the Northern Neck to the Maryland/Delaware portion of the Eastern 
Shore. Conditions farther southeast have stabilized evidenced by a more 
spars cumulus field. MLCAPE values over the Piedmont are on the order 
of 1000-1500 j/kg...with minimal deep layer shear. Hence storm 
organization will be pulse in nature. A few stronger updrafts are 
possible...but should be short-lived with minimal shear and 
unlikely to produce large hail or strong wind gusts. 


Showers/thunderstorms should dissipate quickly this evening followed by a 
partly cloudy to mostly clear night. Lows should range from the 
middle to upper 60s. Locations over the Piedmont that have received 
rain this afternoon could potentially have some patchy fog 
overnight. 


&& 


Short term /6 am Saturday morning through Monday/... 
the primary trend amongst 12z/29 numerical models is an overall 
slower progression with respect to the longwave pattern Saturday 
through Monday. Middle/upper level ridging is expected to remain 
strong along the middle Atlantic and southeast coasts through Sunday. 
This will allow our period of Summer-like weather to continue. 
Continuity will be maintained Saturday with probability of precipitation at or below 10% as there 
is little forcing underneath the ridge. A shortwave trough lifts 
across the upper Ohio Valley and eastern Great Lakes Sunday. This 
could provide enough of a trigger for showers/thunderstorms to drift into 
north/northwest portions later in the afternoon and into the evening. A 
30-50% pop is forecast for the northwest half of the area. 
Otherwise...expect a partly to mostly sunny sky Saturday and 
Sunday...with mostly clear to partly cloudy nights. Highs Saturday 
and Sunday should range from the upper 80s to around 90 
inland...to the 70s to low 80s along the coast. 


A better chance for showers/thunderstorms arrives for most of the area by 
Monday afternoon. A northern stream trough drops into the Great 
Lakes...which pushes a cold front toward the middle Atlantic region. 
GFS/European model (ecmwf) each indicate a pre-frontal Lee-side trough...and the 
GFS additionally depicting a weak surface low over the northern middle- 
Atlantic. This should provide low-level convergence in what is 
forecast to be a warm/humid unstable airmass. Forecast probability of precipitation range 
from 20-30% over far southeast portions...to 40-50% over the northwest half of 
the area. Sky condition should be partly to mostly cloudy...with 
highs ranging from the middle 70s N/NW...to the low/middle 80s southeast...and 
locally cooler along the immediate coast. 


&& 


Long term /Monday night through Friday/... 
low pressure settles over the region Monday night through Tuesday...then 
becomes shunted south of the Virginia/NC border by Wednesday morning. Expect 
unsettled conditions with periods of showers and thunderstorms 
(although Monday appears to be the best day for widespread rainfall 
across the entire fa). High pressure builds in from the northwest Wednesday 
afternoon through Thursday and then slides off the Delaware-Maryland-Virginia coast by Thursday 
night. With high pressure off the coast...any chance for 
showers/storms should stay west of the middle Atlantic region. Long 
range models are hinting at a coastal low developing anywhere from 
the southeast coast to moving the Cape Hatteras coastline Friday into next 
weekend. There are significant timing differences and have 
preferred to lean the far extended portion of the long term 
forecast more toward climatology across the far southwestern area of the forecast area. 
High temperatures generally in the middle-upper 70s during the more rainy 
periods Tuesday/Wednesday with a warm-up into the low 80s for the end of the 
week (roughly 5 degrees cooler at the beaches). Lows Monday night 
through Friday night generally in the low-middle 60s (roughly 5 degrees 
warmer at the beaches overnight). 


&& 


Aviation /20z Friday through Wednesday/... 
cumulus field developed quickly this morning...but current satellite 
imagery shows that the cumulus field is beginning to thin as high 
pressure builds into the area from the east. Scattered convection 
as formed in the Virginia Piedmont as a result of the increasing southeast flow 
around the high centered over the New England coast. These storms 
will continue to move west away from terminal locations. This area 
of high pressure will slowly slide off the coast tonight and 
outside of some lingering low level moisture...will see drier air 
aloft move in. This will allow for VFR conditions to continue 
tonight into the day on Saturday. The cumulus field should dissipate 
tonight and will not be a prominent tomorrow with the drier air 
around. 


The next chance for MVFR to IFR conditions would be beginning 
Sunday night through early Tuesday as a cold front slowly moves 
into the area and convection is expected to develop along and 
ahead of the front. 


&& 


Marine... 
a diurnal increase in onshore Ely winds has been observed this 
afternoon with wind speeds around 10kt with gusts to around 15kt over 
the waters...including the eastern Virginia rivers and Currituck Sound. 
Winds are expected to diminish shortly after sunset as the wind 
direction becomes more south-southeast. Waves 1-2 feet and seas 2-3 feet. As high 
pressure remains over the western Atlantic through the weekend... 
winds remain south-southeast with afternoon/early evening surges in speeds but will 
they will stay within sub-Small Craft Advisory conditions (i.E. Generally at or below 
15kt/seas 2-3ft/waves 1-2ft but up to 2-3ft during surges). Seas 
will reach up to 4ft out near 20nm Sat night through early next 
week. The overall flow weakens Monday into early next week as a 
cold front settles into the region. Expect increasing NE flow by 
middle week.
