NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
409 PM EDT Wednesday Jul 30 2014 


Synopsis... 
high pressure will slide off the coast for tonight into Thursday. 
A frontal boundary will develop along the coast by Friday...then 
move inland through the weekend. 


&& 


Near term /until 6 am Thursday morning/... 
weak hi pressure over the region was providing another comfortable afternoon 
undr a partly to mostly sunny sky. Dewpoints ranged through the 50s to 
near 60...and temperatures ranged from the upper 70s to lower 80s. The hi will 
slide offshr tonight into Thursday morng...resulting in a dry forecast under a 
mostly clear to partly cloudy sky. Still rather comfortable night 
with lows ranging from the upper 50s to middle 60s. 


&& 


Short term /6 am Thursday morning through Saturday/... 
trough aloft will weaken/shift westward into the Ohio/TN/MS valleys 
Thursday into Friday. Weak surface hi pressure will be off the CST Thursday...with south-southeast 
low level flow across the area. A gradual increase in humidity is 
expected...but still should be a dry day with warmer temperatures. Under 
a partly or mostly sunny sky...highs will be in the middle to upper 
80s. 


During Friday...Bermuda hi pressure rebounds across the western Atlantic...with 
deep layered southwesterly flow aloft (ovr the eastern seaboard) and a surface 
frontal boundary developing along the southeast Virginia/NE NC CST. In 
addition...an easterly surface flow from the Atlantic will provide increasing 
low level moist. The combination of these features will result in 
increased shower/thunderstorm chances...esply Friday aftn/eveng...and thus will 
carry solid chance probability of precipitation (40-50%). With plenty of clouds around and 
precipitation possible...hi temperatures on Friday will likely be a touch cooler than 
Thursday...in the lower to middle 80s. 


Friday night and Sat...the frontal boundary will nudge inland a bit 
more...at least into eastern portions of the area. With a continued 
moist surface-aloft flow over the region...and weak low pressure areas moving 
north-northeast along the boundary...have gone with likely probability of precipitation (60%) 
everywhere during this time. Expecting plenty of clouds...so highs 
on Sat will be in the upper 70s to lower 80s. Lows Friday night ranging from 
the middle 60s to lower 70s. 


&& 


Long term /Saturday night through Wednesday/... 
a stalled frontal boundary and associated plume of Atlantic moisture 
will linger over the middle Atlantic Saturday night through Monday 
between a strong ridge over the western Atlantic...and a trough over 
the Midwest. Generally expecting mainly diurnal afternoon/evening 
showers/thunderstorms Sunday and Monday...with lingering overnight/early 
morning showers. A cold front drops through the Great Lakes Monday 
night and Tuesday...and then into the Ohio Valley by midweek. This 
will shove the plume of moisture offshore...with probability of precipitation gradually 
diminishing to slight chance northwest-southeast by midweek. Highs should average in 
the low/middle 80s Sunday/Monday...and trend upward to the middle/upper 
80s Tuesday...and upper 80s to around 90 Wednesday. Low temperatures 
should generally be in the upper 60s to low 70s. 


&& 


Aviation /19z Wednesday through Monday/... 
VFR and dry through the 18z taf period. Surface high pressure slides offshore 
this eveng. This will lead to areas of sky clear with some scattered/broken 
middle-level clouds possible at times. Winds stay light through the period. 


Outlook...dry weather is forecast through Thursday. There will be a 
a chance for mainly afternoon/evening thunderstorms Friday into the weekend. VFR 
is expected outside of precipitation through the weekend. 


&& 


Marine... 
weak high pressure will drift farther offshore tonight into Thursday 
night. The wind should average 5-10kt out of the south-southeast. A 
coastal/inverted trough develops along the southeast and middle 
Atlantic coasts Friday and Saturday. The wind will become easterly 
Friday...and shift to southeast by Saturday with speeds averaging at or below 15kt. 
The trough pushes inland Sunday and Monday with the wind becoming 
southerly and remaining at or below 15kt. Seas should average 2-3ft...with 
1-2ft waves in the Bay. 


&& 


Akq watches/warnings/advisories... 
Maryland...none. 
NC...none. 
Virginia...none. 
Marine...none.
