Area forecast discussion 
National Weather Service Wakefield Virginia 
401 PM EST Friday Feb 12 2016 


Synopsis... 
low pressure lifts northeast off the Virginia coast this evening. 
Arctic high pressure builds in for the upcoming weekend...resulting 
in the coldest temperatures so far this year. Low pressure lifts 
from the deep south into the middle Atlantic region early next 
week. 


&& 


Near term /until 6 am Saturday morning/... 
latest surface analysis centers 1014mb surface low pressure off the NC coast 
this afternoon...with high pressure centered just off the middle- 
Atlantic coast. Regional radar mosaic depicts area of light snow 
moving across east/southeast Virginia...with observation and radar returns 
indicating heaviest snow over NE NC. The heaviest band of snow/sleet 
and frontogenetic forcing remains along and just south of the 
Albemarle Sound. This will continue to be the highlighted area for 
the next few hours. Light snow will wind down across eastern Virginia into southeast 
Virginia by 5 PM...with little additional accumulation. Advisories remain 
in effect with an additional 0.5 inch of snowfall still possible 
back into Isle of Wight and Southampton counties. The surface low 
deepens and lifts northeastward as the upper level wave pushes offshore. Snow 
band will pivot into southeast Virginia late today before the light snow finally 
pushes offshore early this evening. The Arctic boundary then pushes 
through the region this evening. Have increased probability of precipitation for the Maryland Eastern 
Shore to likely late this evening as shortwave energy along the 
Arctic boundary will likely result in additional light snow. 
Accumulations will generally range from 1 to 2 inches. Northwest winds 
increase behind the Arctic boundary...increasing to 10 to 20 miles per hour 
with gusts 25 to 30 miles per hour coastal areas and the Eastern Shore. Sky clears 
SW to NE late tonight...with overnight lows falling into the teens 
to low 20s. Wind chills will drop into the single digits. 




&& 


Short term /6 am Saturday morning through Monday/... 
deep upper trough locates over New England into the Middle-Atlantic 
States Sat as the Arctic boundary pushes offshore. Polar front 
prognosticated to remain north of the local area. The Arctic high builds 
into the Ohio Valley late Sat...ushering in some of the coldest air of 
the season. 850 mb temperatures plummet to around -18 to -20c (-2 to -3 Standard 
dev). Highs only forecast in the middle/upper 20s inland to low 30s southeast. 
Windy...with northwest winds generally 15 to 25 miles per hour with gusts 30 to 
35 miles per hour. Gusts over the Eastern Shore and coastal areas expected to 
reach 40 miles per hour. While the air mass remains very dry (dewpoints below 
0)...Bay streamers and light snow showers are possible over the Eastern 
Shore. Will hold onto slight chance probability of precipitation there. Sky averages sunny 
southwest to partly cloudy NE. Large scale confluence in wake of the 
departing upper low will allow high pressure to build into the 
region Sat night. Winds diminish inland...allowing for great 
radiational cooling and lows plunging into the single digits to low 
teens inland to upper teens near the coast. Wind chill values 
generally 0 to 5 above inland and around 5 below Northern Neck to the Eastern 
Shore. Will hold off on Wind Chill Advisory at this time. 


The Arctic high centers over the middle-Atlantic sun...with highs only 
warming into the middle/upper 20s (-2 Standard dev). Sky averages mostly 
sunny with a light New York wind. Middle/upper level clouds begin to increase 
late Sunday as the next storm system approaches. 


The high shifts toward New England Sun night as the next storm 
system develops over the deep south Monday. Northern stream energy lifts 
north of the region Sun night/Monday as a middle level trough tracks 
across the central Continental U.S. Monday. Southwesterly flow aloft will result in 
moisture return into the middle-Atlantic region. Probability of precipitation increase late Sun 
night as the northern stream system weakens and weak isentropic lift 
advects into the region. Air mass will easily be cold enough Sun 
night for all snow as lows Sun night will be in the upper teens to 
around 20. Precipitation chances increase Monday as a coastal trough sharpens 
along the coast and the aforementioned deep south low begins to lift 
northeastward toward the local area. Have increase probability of precipitation to likely across the 
northwest Monday morning...with likely probability of precipitation across all but southeast Virginia/NE NC Monday 
afternoon. Warm air advection aloft/critical thicknesses still indicating a change 
over from snow/ice pellets Monday morning to rain closer to the coast Monday afternoon. 
Ptype likely to remain all snow northwest. There still remains some timing 
and spatial differences in the models...but current snowfall 
forecast calls for 1-2 inches along the Interstate 85 corridor into 
central Virginia and northern Virginia...with 2-4 inches across the northwest counties. 


&& 


Long term /Monday night through Friday/... 
12/12z numerical models depict low pressure tracking NE from the 
deep south to the southern Appalachians Monday evening...then rapidly 
deepening as it lifts NE into the middle-Atlantic region by midday 
Tuesday as a vigorous upper trough digs across the southern/central 
Appalachians. Thermal profiles suggest mixed precipitation could continue 
into the evening over the Piedmont. Overnight lows should occur in 
the evening...with rising temperatures overnight as the low-level 
flow becomes south-southeast. Colder temperatures will likely persist the 
longest in the far northwest Piedmont counties where some pockets of -fzra 
could continue overnight...but generally all rain is expected by 
early Tuesday morning. Periods of moderate rain are possible late 
Monday night into Tuesday as a band of strong vertical ascent passes 
over the region. Strong pressure falls could produce a modestly 
strong southerly wind across the eastern third of the area for a 3-6hr 
period Tuesday. Temperatures warm to at least the middle/upper 50s 
across the eastern half of the area Tuesday...with low 60s possible 
along the coast...while the Piedmont struggles to rise above the 
upper 40s/low 50s. Generally expecting drier conditions by Tuesday 
night...although some 20-30% probability of precipitation will linger across the north as a 
secondary trough swings across the northern mid-Atlantic. Dry and mild 
Wednesday under west-northwest flow with highs in the upper 40s to middle 50s. A 
cold front tracks across the area Wednesday night...followed by 
Canadian high pressure Thursday. This should push temperatures below 
normal...but within -1 St dev. A moderating trend commences late 
week as high pressure moves offshore and low pressure tracks through 
the Great Lakes. 


&& 


Aviation /21z Friday through Wednesday/... 
weak surface low pressure will be exiting NC/SC CST this aftn/eve. Broad area 
of snow to move across mainly southeast Virginia/NE NC. Period of MDT snow possible from about 
20-23z/12...especially at ecg. Elsewhere...dry low level atmos xpd to prevent 
anything more than flurries ric-sby. 


Trough aloft to push across the region tonight...ptntl for scattered -sn...mainly 
in vicinity of sby from about 02-03z to 08-09z/13. Otherwise...strong cold front to push 
across the region overnight. Gusty northwest winds to 25-35 knots to develop lt 
tonight/early Sat morning...continuing through the day Sat. VFR and dry weather 
will prevail Sat through Sun night. Precipitation develops Monday as the next 
weather system approaches from the west. Precipitation begins as snow Monday morning...mainly 
inland...before warmer air works in and changes any snow to rain from 
southeast to northwest during Monday. Rain continues into Tuesday as low pressure tracks across 
the area. Dry weather returns Wednesday. 


&& 


Marine... 
low pressure is tracking east-northeast off the NC coast this 
afternoon. Meanwhile...another area of low pressure is tracking 
across the eastern lakes...with an Arctic cold front trailing through 
the Ohio Valley...and Arctic high pressure spilling into the upper 
Midwest. The coastal low will bring a period of snow...which will 
reduce visibility late this afternoon and evening (mainly s). As the low 
lifts to the NE tonight the Arctic cold front will pass across the 
region with strong cold air advection developing late tonight...and continuing 
through Saturday into Saturday night as the Arctic high builds in 
from the northwest. A northwest wind will average 25-30kt with frequent gusts of 
35-40kt over the ocean and Bay. Seas build to 5-8ft with 4-5 feet 
waves in the Bay. Gale flags continue for late tonight through 
Saturday night. For the rivers and sound...wind speeds remain capped 
at high-end Small Craft Advisory at this time. Freezing spray is expected as 
temperatures plummet Saturday and especially Saturday night/Sunday 
morning...with a freezing spray advisory in effect for Saturday 
night into Sunday morning. The wind will diminish Sunday into Sunday 
night as the high settles across the area. Low pressure approaches 
form the SW early next week...and tracks up the Piedmont Tuesday. 
This will allow for a modestly strong south-southeast wind and building 
seas/waves. 


&& 


Tides/coastal flooding... 
strong northwest flow associated with an Arctic cold front could produce 
blow-out tides / low water advisories Saturday afternoon and night.
