NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Raleigh NC 
330 am EDT Friday Apr 25 2014 


Synopsis...a warm front will lift north through NC and Virginia early 
today...ahead of a cold front that will cross the region late this 
afternoon and evening. Weak high pressure will follow for tonight 
through Sat...before a backdoor cold front settles into the area 
from the north Sat night and sun. 


&& 


Near term /through tonight/... 
as of 325 am Friday... 


Principle forecast concern for today will be the evolution of 
convection - some severe - in a complex surface pattern downstream 
of a primary surface low and trailing cold front analyzed from Illinois 
southwestward through the lower MS valley/to southern Texas this 
morning. A warm front in advance of the parent low - one that Marks 
the leading edge of boundary layer moisture supportive of 
surface/mixed layer-based convection - will retreat quickly 
northward with a strengthening low level jet...from the Savannah basin and 
across the Carolinas this morning. This boundary will continue to 
develop/retreat northward and assume an increasingly northwest to southeast 
orientation from north-central Virginia southeastward to the Virginia 
Tidewater/NE NC this afternoon. 


Aloft...a compact negatively-tilted shortwave trough near the MO 
bootheel will deamplify east-northeast across the central Appalachians and 
Middle Atlantic States this afternoon - slightly outpacing the 
synoptic surface cold front...which is not expected to cross central 
NC until between 23-04z this evening. The focus for convection today 
will consequently likely be in association with 1) the warm front 
early in the day...when initially scattered elevated showers...will 
become increasingly rooted in the boundary layer owing to both 
diurnal/diabatic heating and boundary layer moisture recovery/ 
transport with the passage of the warm front...and 2) along a pre- 
frontal surface trough/confluence axis that will develop from 
western NC eastward across the Piedmont and coastal plain this 
afternoon - coincident with the concentrated forcing for ascent 
attending the aforementioned shortwave trough. 


Thermodynamics will be good...with 850 mb-5 lapse rates forecast to 
exceed 6 c/km owing largely to differential thermal advection in 
that layer. In addition tot he steep lapse rates aloft...steadily 
increasingly middle level flow/0-6 km bulk shear in association with 
the approach/arrival of the shortwave trough/middle level jet will 
prove sufficient for storm organization...and an associated threat 
of large hail and damaging winds area-wide. However...the likelihood 
of supercells will be maximized over the eastern sandhills and 
coastal plain northeastward into south-central/southeastern Virginia - in 
an area bounded by the pre-frontal trough to the west and the warm 
front to the northeast. Surface flow will be locally backed in those 
areas...such that cyclonically-curved forecast hodographs will 
lengthen/srh values will increase into the 200-300 m2/s2 range - 
supportive of isolated tornadoes. 


Although it will remain unstable behind the pre-frontal 
trough...veered surface flow and the loss of larger scale forcing 
for ascent accompanying the passing shortwave trough will end the 
severe weather threat and cause the surface cold front to pass with 
relatively little fanfare this evening...with perhaps a band of 
widely scattered showers and an isolated storm - if that. 
Otherwise...it will be breezy and warm today...with highs in the 
middle 70s to around 80 degrees...but with a distribution modulated 
by pockets of denser cloud cover and convection. 


A subsident...cooler...and drier air mass will follow the cold front 
eastward and result in clearing skies...with lows generally 50-55 
degrees tonight. 


&& 


Short term /Saturday through Sunday night/... 
as of 300 am Friday... 


Dry weather with seasonable temperatures will ensue for the weekend 
in the wake of the cold front Friday night as a mild surface high 
surface builds into the area lower MS valley/northern Gulf Coast 
states on Saturday. A compact upper low/trough over the upper Great 
Lakes will move eastward-southeastward through southern New England 
on Sunday. Attendant height falls aloft across the northern Middle- 
Atlantic States will drive a secondary back-door cold front 
southward into the area Sunday and Sunday night...thats forecast to 
stall and wash out across the area as it encounters increasing 
heights aloft as shortwave ridge builds into the area from the 
southwest. Other than a few clouds...expect little sensible weather 
from this feature with continued dry conditions to close out the 
weekend. Highs one category above normal...75 to 80. Lows in the 
lower to middle 50s. 


&& 


Long term /Monday through Thursday/... 
as of 300 am Friday... 


An active and unsettled weather pattern looks to be in the cards 
from the MS valley eastward for much of the upcoming work week.. 
owing to the development of a strong closed upper low over the 
southwestern US that will drift slowly north and east...hampered by 
a developing Rex block over south central Canada. 


While models are are in good agreement with the overall big 
picture/location of synoptic features...finer forecast details are 
still currently beyond model resolution...further complicated 
locally with model depiction of an early warm season damming event 
across portions of the Carolinas and virginias Monday and into 
Tuesday with a warm/wedge front bisecting southern portions of the 
area. Sensible weather impacts Monday and into Tuesday could be 
delayed until the middle to late week time period...with central NC 
lying underneath the formidable ridging aloft...downstream of the 
upper juggernaut and east of the stronger southern moisture feed 
thats looks to remain largely west of the mountains. Such an idea 
fits well with the large scale blocking upper air pattern that will 
be in place with the more significant threat of heavy rain and 
severe storms coming Wednesday and into Thursday. Forecast should 
become clearer/less murky by Sunday once the upper low forms. Until 
then...will favor forecast continuity with continuation of high 
chance/likely probability of precipitation. Widespread clouds and prospects of precipitation should 
keep temperatures near normal... and possibly even a good 5 to 8 
degrees below normal Monday and Tuesday across the northern portions 
of the Piedmont...north of The Wedge front. Warmer more uniform 
temperatures by Thursday as wedge sector overtakes the area. 




&& 


Aviation /06z Friday through Tuesday/... 
as of 200 am Friday... 


A developing southerly return flow in anti-cyclonic flow around high 
pressure along the coast...will cause low level moisture to increase 
over NC this morning...such that IFR-MVFR stratus clouds are likely 
to develop and affect portions of central and western NC in the few 
hours surrounding 12z - lowest and most likely at triad terminals. 
The passage of a warm front this morning will also support the 
development of scattered showers between 11-16z...followed by a 
breezy SW surface wind and showers and thunderstorms becoming 
numerous this afternoon...ahead of a cold front that will cross the 
area late this afternoon and evening. Clear and cooler conditions in 
west-northwest Post-frontal flow will follow for tonight. 


Outlook: unsettled weather - with periods of sub-VFR conditions and 
rain/showers/thunderstorms - in the vicinity of a stalled surface 
frontal zone and in a regime of perturbed and moist SW flow 
aloft...will occur early to middle next week. 


&& 


Rah watches/warnings/advisories... 
none.
