NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
907 PM EDT Wednesday Apr 1 2015 


Synopsis... 
high pressure will build over the area tonight...then gradually 
shift off the coast on Thursday. The next cold front approaches 
from the northwest on Friday...and crosses the region Friday night 
into Saturday morning. High pressure returns from Saturday 
afternoon through Easter Sunday. 


&& 


Near term /until 6 am Thursday morning/... 
clear skies and lght winds resulting in good radiational cooling this 
evening as temperatures have dropped some 10-15 degrees in some areas since sunset. 
Given the current deep temperatures...lows should drop into the m30s most areas 
xcpt l30s in the normally colder spots along the rt 460 corridor 
east of ptb and inland sections of the Eastern Shore. 


A frost adsy remains in effect for most of the zones that have 
started the growing season today (april 1st). This includes the 
NE NC counties from Chowan east to the Atlantic coast / Chesapeake / 
Virginia Beach. Kept Norfolk and coastal/Outer Banks Currituck out of 
it due to slightly warmer temperatures west/ a few knots of wind anticipated. 
It should be noted that counties in the adsy along the sound and 
along the Atlantic coast (va beach oceanfront) will likely be a few 
degrees warmer and frost is unlikely...just that we do not have 
the ability to issue polygon-based frost advisories. Patchy frost 
also possible farther inland in NC and Virginia...but these zones do not 
start the growing season until April 8th or later. 


&& 


Short term /6 am Thursday morning through Saturday/... 
with surface high pressure axis offshore by middle/late thus morning and 
a weather disturbance approaching the region from the SW...the area 
will be within a warming airmass as breezy south winds develop by 
the afternoon. Most inland locations should reach around 70 f under 
mostly sunny skies...with highs in the l/m60s at the immediate 
coast. 


Increasing clouds Thursday night as upper ridge axis shifts off the 
coast and a more moist SW flow aloft develops. In general...models 
remain slower at bringing in deep moisture and the northern stream and 
southern stream are slower to phase. Will continue west/ highest probability of precipitation on Friday 
to north-northwest 1/3rd of forecast area by early Friday am through Friday afternoon. Very mild 
Thursday night in south-southwest flow and increasing clouds...lows in the 50s to 
possibly as warm as 60f in a few spots. Warm/variably cloudy Friday 
with 20-30% chance for -shra and perhaps some late day thunderstorms as the 
surface front moves closer to the region. Highs mainly in the 
M/u70s to around 80f (u60s/l70s on the eastern shore). Main rain 
event looks to hold off until Friday night...as the actual front 
moves through the County Warning Area from northwest to southeast from 06-12z. Not a long period 
of deep moisture and lift with this front however...and given some 
continued model discrepancies regarding these features will keep 
probability of precipitation in the high chance range Friday night...except likely across the 
north. Lows Friday night mainly in the 50s. Dry air moves in from northwest 
to southeast Sat morning...and most areas should be dry after 15z. Temperatures 
aloft cool...but a downslope west-northwest flow should allow for highs 
mainly 60-65 f under afternoon sunshine. 


&& 


Long term /Saturday night through Wednesday/... 
high pressure builds across the Tennessee Valley and into the southeastern 
states/middle Atlantic region Sat night into sun...sliding off the 
Carolina coast by sun evening. Aside from some breezy northwest winds 
along the immediate coast Sat night...the middle Atlantic region will 
experience relatively quiet and dry conditions Sat night through 
early next week. Highs will begin at to slightly below average on 
sun (upper 50s to low-middle 60s) and then warm 3-5 degrees each 
consecutive day with forecast highs generally in the lower 70s 
(mid-upper 60s at the immediate coast) by Tuesday. Overnight lows will 
experience the same gradual warming trend with lows in the upper 
30s to lower 40s Sat night...warming roughly 5 degrees each night 
with lows in the low-middle 50s forecast for Tuesday night. Timing varies 
regarding when the next chance for precipitation is expected to 
occur. The GFS model brings intermittent periods of light rain 
showers to the area Monday evening through Wednesday...while the European model (ecmwf) 
model does not bring rain to the area until Wednesday. Went with a long 
range model blend to average out rain chances during the 
aforementioned timeframe. 


&& 


Aviation /01z Thursday through Monday/... 
calm to light winds will prevail overnight as high pressure will 
remain centered over the region. The high slips off the coast for 
Thursday with gusty S/SW winds by midday. Low dew points will prevent 
fog formation for Thursday morning. A mainly clear sky is 
indicated with only scattered high clouds. 


Outlook...the passage of a cold front will bring a chance for 
showers and thunderstorms late Friday and Friday night. Otherwise a 
dry forecast is in place through Monday. 


&& 


Marine... 
Small Craft Advisory flags cancelled for southern coastal waters now that seas are 
finally falling below 5ft as high pressure settles over the waters 
through tonight. Light northerly winds veer around to the south after 
midnight tonight and remain light (aob 10kt). High pressure slides 
off the coast by Thursday afternoon and the surface pressure gradient begins to 
tighten ahead of an approaching cold front. Breezy S winds begin 
to increase in northern waters Thursday afternoon and then become widespread 
across all waters by Thursday evening. Speeds will average 15-20kt with 
gusts of 20-25kt (up to 30 knots in northern coastal waters). A new round 
of Small Craft Advisory flags have been issued for the northern coastal waters from 
Fenwick Island to Parramore Island and all of ches Bay beginning 
Thursday afternoon through at least Friday afternoon. Coastal waters from Parramore 
Island to the Virginia/NC border may briefly reach Small Craft Advisory gusts of 25kt Thursday 
evening...but the duration anticipated is not long enough to 
justify Small Craft Advisory flags at this time. Waves will average 2-3ft Thursday afternoon through 
Thursday night. Seas will average 2-3ft...building to 3-5ft northern coastal 
waters Thursday evening. 


A cold front approaches the waters on Friday and pressure gradient 
winds tighten further with SW winds averaging 20kt with gusts of 
25-30kt throughout the day. Waves average 3-4ft and seas build to 
3-5ft all coastal waters by early Friday evening. The front crosses 
the waters late Friday night into Sat morning...resulting in a quick 
surge of winds/seas with the frontal passage. Conditions remain 
well-rooted in Small Craft Advisory flags on Sat in the Post-front environment as 
winds/gusts become northwesterly and seas average 4-6ft north of Cape 
Charles and 3-5ft south of Cape Charles. Ongoing Small Craft Advisory flags from 
Thursday will likely be extended through Sat...and any waters not 
within Small Craft Advisory flags will likely be in them by early Friday morning 
(beginning roughly around daybreak). High pressure builds back 
into the region by Sat evening and all conditions (winds/waves/seas) 
are expected to diminish below Small Craft Advisory criteria. High pressure settles 
over the waters sun through early Monday with southerly winds remaining 
at or below 15kt. 


&& 


Fire weather... 
the combination of low relative humidities and gusty south to 
southwest winds will produce an increased fire danger threat 
Thursday afternoon. Sustained winds of 15 to 20 miles per hour with gusts to 
25 miles per hour and relative humidity levels dropping between 20 to 30 
percent are expected during the afternoon hours. 


&&
