NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
410 PM EST Monday Dec 22 2014 


Synopsis... 
low pressure will linger along the Carolina coast today through 
Tuesday. A strong cold front will cross the area Wednesday night. 
High pressure builds back in from the southwest Christmas day 
through Friday. 


&& 


Near term /through Tuesday/... 
current analysis depicts ~1031 mb surface high pressure centered over 
novia Scotia...ridging SW into the northern middle Atlantic region. Wedge/cad 
setup is in place but temperatures are above freezing throughout 
the County Warning Area ranging from 34-35 across the northwest Piedmont to the Lower-Middle 
50s at kecg. Surface trough of low pressure is situated off the 
Carolina coast. Best lift and Omega has shifted to the Eastern Shore 
with mainly just drizzle or very light rain for the rest of the 
area. Will maintain chance probability of precipitation across SW zones to likely/categorical 
elsewhere even though quantitative precipitation forecast amounts will be very light. Temperatures 
will change only slightly from current values...with lows 33-35 f 
over northwest Piedmont...to 45-50 f southeast coastal areas. Dew points have risen 
today...and with little in the way of wind later tonight and Tuesday 
(as coastal trough weakens)...think fog will become a concern just 
about anywhere (including the water). Have fog in the gridded 
forecast all areas after midnight and through midday (at least) on 
Tuesday. As for probability of precipitation later tonight...generally expecting only minimal 
additional quantitative precipitation forecast as infrared satellite shows area of cooling cloud 
tops/heavier precipitation along the coast likely to stay offshore. 
Models do hint at some increase in probability of precipitation after midnight west/ next 
weak shortwave aloft so will carry high chance probability of precipitation after midnight. 


Favored cooler met guidance for highs Tuesday...given a light onshore 
flow and strengthening inversion. Highs generally will range from the 
Lower-Middle 50s west of I-95 to the middle-upper 50s far southeast zones. Mot 
much support for precipitation other than continued drizzle and areas of 
fog. 


&& 


Short term /Tuesday night through Thursday/... 
Tuesday night/ Wednesday...surface warm front will lift north across the 
region later Tuesday night and will allow for the area to be warm 
hectored on Wednesday. Deep moisture transport occurs Tuesday night...raised 
probability of precipitation to near 100% Tuesday night...as moderate to heavy rain moves 
through the region. Potential for lingering fog over northwest areas 
where low level wedge is slower to scour out. Still decent model 
agreement with ~990 mb surface low tracking nine from the Tennessee Valley to 
the Great Lakes during the day Wednesday. Dew points soar into the upper 
50s to Lower-Middle 50s in strong southerly flow on Wednesday...so will 
continue mention of slight chance for for late after/evening thunderstorms on 
Wednesday (christmas eve). At this point there does not look to be much 
in the way of clearing potential (high shear but very minimal 
cape) on Wednesday to lead to severe excessive. Cps only has far southeast zones in a 
marginal risk attention. Timing also a bit slower...actual front now 
pronged to push through around 06z/Thu...which would further limit 
severe potential. Highs Wednesday into the M-u60s to lower 50s (close to record 
highs/see climate section). Categorical probability of precipitation all areas 
Wednesday...shifting off the coast later Wednesday night as the cold front 
pushes through and drier air moves in from the west by Christmas 
morning. Slower passage of the front will make for very mild mins 
Christmas morning with lows in the middle 50s far west...to the middle 
50s southeast. Skies become mostly sunny with breezy westerly flow by 
middle/late morning Christmas day. Raised highs to 55-60 f most areas 
as cold air advection is weak and will be offset by downslope warming (and due to 
a warm beginning). 


&& 


Long term /Thursday night through Monday/... 
high pressure builds across the southeast states and middle Atlantic region 
Thursday night/Fri...sliding off the southeast coast Friday night. A cold front 
gets sheared apart as it crosses the area Sat night into early Sun 
morning and should be relatively dry with a slight chance of light 
showers possible with its passage. The cold air advection occurring behind the 
front is becoming weaker with each model run so am not anticipating 
a significant cool down in its wake...except maybe in colder 
overnight lows. High pressure builds back into the region from the 
west sun through at least Monday. Highs should be in the middle-upper 50s 
Fri/Sat...then cool into the upper 50s to around 50 sun/Mon. Lows 
will generally be in the 30s (occasionally in the lower 50s 
immediate coast). 


&& 


Aviation /21z Monday through Saturday/... 
low pressure moving off the Outer Banks along with high pressure 
wedging south will continue the cool/rainy period through 
tonight with IFR vis/cigs. Expect 15-20 knots winds along the coast 
to continue through Monday evening as the low moves north and the 
pressure gradient tightens. Cool northerly flow continues through 
Tuesday after helping to keep IFR stratus and visible through the 18z taf 
period. 


Outlook...a series of low pressure systems and complex frontal 
boundaries will bring chances for rain and periods of low ceilings 
and visibilities through Wednesday. A cold front passes through 
Thursday morning with VFR conds and dry weather Thursday and Friday. A 
period of gusty winds expected Wednesday afternoon through midday 
Thursday ahead of and behind the front. 


&& 


Marine... 
north-NE winds 15-25kt across the Bay/sound/coastal waters from 
Parramore Island to Currituck light and waves 3-4ft (up to 5ft 
possible in the mouth of the bay) will persist until 7 PM this 
evening. 4-7ft seas in the aforementioned coastal waters will be 
slower to subside and Small Craft Advisory flags will remain in effect until 4 am 
tonight. Meanwhile...the surface low pressure located just off the Cape 
Hatteras coast late this afternoon will continue to track north-northeast up the middle 
Atlantic coast tonight...washing out off the Delaware-Maryland-Virginia/New Jersey coast on 
Tuesday. 


Light and variable winds later this evening/overnight will become 
east-southeast on Tuesday as upper level high pressure remains in place over the 
middle Atlantic region...and the next low pressure system organizes 
over the deep south. Southeast winds gradually begin to increase to 15-25kt 
late Tuesday night as a warm front lifts north through the area. A 
strong cold front approaches the waters from the west on Wednesday 
with winds becoming more southerly and increasing to solid Small Craft Advisory speeds of 
20-30kt across all waters except the rivers...where the fetch is not 
favorable for Small Craft Advisory conditions in southerly flow. Seas will also build to 
5-7 feet on Wednesday before subsiding again by late Thursday. Waves on ches Bay 
will reach 4ft during this timeframe. The front quickly sweeps 
through the area Wednesday night and offshore early Thursday. Winds remain 
above Small Craft Advisory levels through Thursday evening while becoming SW Wednesday 
night/early Thursday then west by Thursday afternoon. High pressure builds across the 
southeast states and middle Atlantic region Thursday night/Fri...sliding off the southeast 
coast Friday night. A dry cold front crosses the waters Sat night and 
the cold air advection that follows is becoming weaker with each model run. High 
pressure builds into the region from the west sun through at least 
Monday. Expect improved conditions late Thursday evening through the weekend 
and into early next week with variable wind directions at or below 15kt.
