NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
343 PM EDT Wednesday Apr 23 2014 


Synopsis... 
cool Canadian high pressure slowly builds in from the northwest 
overnight. High pressure then slides over the region into Thursday 
morning...locating off the southeast coast Thursday afternoon. A 
series of weak fronts will cross the area Friday into the weekend. 
A period of unsettled weather is expected over the area early next 
week. 


&& 


Near term /until 6 am Thursday morning/... 
temperatures have warmed into the middle-upper 60s to near 70 across the 
region this afternoon under mostly sunny skies. The exception is 
the Eastern Shore where temperatures have only warmed into the low 60s. Upper 
trough axis has shifted offshore per latest water vapor 
imagery...as surface high pressure builds southward from the Great Lakes 
region. The result will be clear skies overnight and decreasing northwest 
winds. With the high pressure to the west of the area...another 
round of cold air advection overnight will push temperatures into the middle-upper 30s 
inland and into the low 40s near the coast. Winds will not 
completely Delaware-couple tonight...ranging from 5-10 miles per hour inland to 10 
to 15 near the coast. Combine light mixing with rather dry ground 
conditions and low dewpoints...do not anticipate widespread frost 
and will leave out of grids. However...patchy frost is possible in 
sheltered locales. 


&& 


Short term /6 am Thursday morning through Saturday/... 
surface high pressure centers off the southeast coast Thursday as an upper 
ridge builds over the eastern Continental U.S.. upper trough over the 
intermountain west will Delaware-amplify and eject northeastward into the plains 
Thursday...pushing an associated cold front into the MS valley. Flow 
returns to the south late Thursday-Thursday night as a warm front lifts 
over the region. Middle-level westerly flow over the Gulf states into the 
middle-Atlantic will prevent much of a moisture return into the 
region....so dry conditions will prevail. Northwesterly winds will not be 
as strong Thursday afternoon...but min relative humidity values in the upper teens- 
low 20s and dry fuels will again result in potential fire weather 
concerns. Please refer to fire weather section below for more 
information. 


Ridge axis pushes offshore Friday morning as the upper wave reaches 
the Ohio Valley. Questions still exist on strength of the upper wave 
as it crosses the middle-Atlantic region Friday afternoon...with the 
latest GFS trending sharper than its previous runs and coming 
more in line with its NAM/European model (ecmwf) counterparts. Cold front will push 
across the region Friday afternoon-evening. Short lived low-level SW 
flow will be able to advect modest precipitation water values of 1-1.25 
inches into the region...but dewpoints only prognosticated to warm into 
the upper 40s to near 50 Friday. With the local area in the warm 
sector Friday...temperatures will warm into the upper 70s to near 80 
(depending on frontal timing). Combination of warm temperatures and 
Theta-E advection will result in a marginally unstable airmass 
(mlcape <500 j/kg)...mostly over eastern Virginia/northestern NC. Also...little 
instability/lift prognosticated in the mixed phase layer so anticipate 
only isolated/slight chance thunder in convection. Just like 
yesterdays front...biggest limitations are west-southwest flow and low 
dewpoints. Shear is also marginal (~30-35 kt) so do not anticipate 
organized convection along the weakly forced front. With that 
said...will maintain chance probability of precipitation over the region Friday afternoon 
along/behind the front. Quantitative precipitation forecast amounts will generally be less than 
one to two tenths. 


Front pushes offshore Friday night as a secondary dry cold front 
associated with an upper low over the Great Lakes approaches from 
the northwest. Breezy westerly/downslope flow Sat and increasing low level 
thickness values will result in daytime temperatures around 80 degrees most 
locales...even behind fridays front. Narrow band of moisture and 
measurable precipitation forecast to remain north of the local area late 
Sat-Sat evening. 


&& 


Long term /Saturday night through Wednesday/... 
models continue to point to a highly amplified/blocky pattern over 
the Continental U.S. Next week...resulting in an increasingly wet period. 


Models continue to struggle with this blocky flow...mainly in 
location of frontal boundary prognosticated to be drapped across the region 
along with timing of several batches of moisture prognosticated to rotate NE 
from the deep south. What todays models show different from ystrdys 
is a slower start to the precipitation Monday...somewhat higher confidence for 
an extended prd of wetness from Monday night through Wednesday along with a frontal 
boundary that will likely play havoc with temperatures. 


Kept sun dry / seasonable as 500 mb ridge builds across the area. Warm 
front apprchs the region from the SW Sun night...but guidance suggests any 
moisture stays west of forecast area through 12z Monday. Lows Sat / sun nights in the 
m40s-l50s. Highs sun 70-75 west of the Bay...M-u60s along the coast. 


Forecast rather problematic next week as the models differ on where 
this frontal boundary sets up. This will likely determine temperatures and precipitation 
types (convective vs stratiformed rain). Upper level low prognosticated to 
slowly eject east from the nations middle section Monday night only to the 
Ohio vlly by Wednesday. A moist east-southeast flow will likely add to the moisture 
content resulting in periodic chances for precipitation through the prd. Frontal 
boundary may also try to make a run farther north by Wednesday as surface low 
begins to cross the mts. Trailing cold front will eventually push 
all this out to sea...but that might not be until Thursday. Upshot 
will carry high chance probability of precipitation (shwrs) Monday through Wednesday. Temperatures coolest 
(l-m60s) along the coast due to an onshore flow. Highs u60s-l70s 
west of the Bay. Lows in the 50s. 


&& 


Aviation /20z Wednesday through Monday/... 
as the front continues to push farther off shore...the pressure 
gradient will tighten up near the immediate coast where west-northwest-northwest 
winds should average close to 20g30kt before tapering off during 
the evening and overnight hours. Northwest wind speeds briefly increase 
Thursday morning and then drop off through the afternoon as high pressure 
slides across the area and becomes located off the southeast coast 
by Thursday evening. 


The next cold front approaches the region Thursday night...causing northwest 
winds to back around to the S-se. The front is expected to cross 
the middle Atlantic region Friday evening...bringing showers and a 
slight chance for thunderstorms to area taf sites. Behind this 
front...winds will generally be northerly around 15 knots or less through 
the rest of the weekend. 


&& 


Marine... 
mixing still producing gusty winds late this afternoon across the waters. 
Expect winds over the rivers and Currituck Sound to slowly dmnsh next 
few hours...so Small Craft Advisory will continue through 7 PM there....10 PM for lower James 
ivof orf. Secondary surge noted in models keeps Small Craft Advisory headlines for 
ches Bay / coastal waters into Wednesday morning. 25-30 knots gusts possible as well. 


High prs builds into the area Wednesday afternoon then shifts offshore Wednesday 
night and Thursday. This results in dmnsh winds and improving seas. 
Thus...sca's will gradually end Wednesday...latest over coastal waters 
where it may take seas a few hours longer to drop below 5 feet. Southeast flow 
becomes S then SW as by Friday as return flow establishes itself on 
back sode of retreating high. 


Next front prognosticated across the region Friday night with a secondary trough 
crossing the waters Sat. Expect conditions to remain below Small Craft Advisory levels 
through Sat...although another weaker northwest surge is possible Sat afternoon. 


&& 


Fire weather... 
a red flag warning remains in effect late this afternoon until 8pm 
for portions of central and eastern Virginia (mainly along and north of 
ric metropolitan area) as well as the lower Maryland Easter shore for dry and 
breezy conditions. Winds of 15 to 20 with gusts to 30 miles per hour over 
interior Virginia...with winds of 20 to 25 miles per hour with gusts to 35-40 miles per hour 
over the Eastern Shore will continue through early evening. Special Weather Statement for 
increased fire danger over the south continues through 8 PM as 
well with winds 10-15 miles per hour with gusts of 25 miles per hour. 


Dry conditions (min relative humidity values 15-22%) will occur again on 
Thursday. However...winds will be below criteria. This will preclude 
the need for any fire weather watches/warnings over our area...except 
for the lower Maryland Eastern Shore where winds may remain elevated. 
However...anyone planning/involved in outdoor burning activities 
should continue to exercise caution. Will therefore mention 
continued dry conditions for tomorrow in the hwo/fwf.
