AREA FORECAST DISCUSSION National Weather Service Raleigh NC 1014 PM EST Thu Dec 5 2019

SYNOPSIS. High pressure will drift overhead and offshore through early Friday. Meanwhile, an upper level disturbance will approach from the west, then cross the Carolinas later Friday into Friday night. High pressure will follow and build down the eastern seaboard through the weekend.

NEAR TERM /TONIGHT/. As of 1010 PM Thursday .

Within multiple branches of the mid-latitude westerlies, the most prominent feature over the CONUS this evening is a former closed low over the cntl Rockies as of 12Z, which has become a positive tilt, open wave trough centered over wrn KS per 00Z upr air and WV satellite data. This feature is forecast to track esewd into AR by 12Z Fri, with weakly anticyclonic flow downstream across the sern US. Meanwhile at the surface, the center of 1022 mb high pressure now over the sern US will drift offshore tonight.

An initial stream of cirrus in wnwly upr lvl flow extending from the mid MS Valley ewd across the lwr OH Valley and srn Appalachians will briefly peak over cntl NC between 06-09Z, then depart the middle Atlantic coast. That cloud cover will remain thin and inconsequential to surface temperatures tonight. Thereafter, an area of moisture/cloudiness centered around 700 mb, between 10-12 thousand ft per observational data over the lwr/mid MS Valley and mid-South and in a mid lvl WAA regime preceding the aforementioned positive tilt trough aloft, will overspread wrn NC by early Fri morning (between 09-12Z). While that cloudiness will arrive too late to appreciably impact low temperatures mostly in the lwr-mid 30s tonight, it will result in a rapid increase in mid lvl overcast -- one generating precipitation aloft-- that will overspread and lower across cntl NC on Fri. These types of mid lvl-generated precipitation regimes, atop an initially relatively dry sub-cloud layer, often over-perform relative to model solutions, including most notably this past Mon morning. As such, it is likely that PoP will require some upward adjustment for Fri-Fri evening, particularly over the Sandhills and srn and cntl Coastal Plain region, where an area of lwr lvl/850 mb WAA centered along the sern US coast will augment otherwise mid lvl lift and moisture over cntl NC.

SHORT TERM /FRIDAY AND FRIDAY NIGHT/. As of 315 PM Thursday .

The surface high centered over the eastern Carolinas early Fri will drift out over the Atlantic Fri/Fri night as a weak frontal zone moves in from the WNW. The aforementioned mid level wave will dampen as it tracks across the Southeast Fri and off the SC/GA coast and offshore Fri night. While this feature will bring a solid deck of clouds, bases will remain fairly high with a dry 5-6 kft subcloud layer, a function of the weak MSLP pattern, broad weak frontal zone, and limited opportunity for moisture return in the lowest few thousand feet, except for perhaps our far SE sections which may see a short period of Atlantic moisture influx around 850 mb. The bulk of the forcing for ascent, including mid level DPVA and upper divergence, will be weakening and holding mostly to our S, so despite the moisture aloft, it will be difficult to generate enough lift to overcome the surface-based dry air, so expect very low QPF. Have kept pops on the low side, slight chance over all but the S and SE where mid-range chances have been introduced, focused from mid afternoon until around midnight. Expect highs in the mid 50s to lower 60s, with the higher readings in the SE where some filtered sunshine is expected early. Lows should be in the upper 30s to lower 40s, although readings should hold in the 40s through much of the night, only falling very late as cooler high pressure begins to build in behind the front toward daybreak. -GIH

LONG TERM /SATURDAY THROUGH THURSDAY/. As of 255 PM Thursday .

Saturday and Sunday: Primarily dry forecast through Sunday. A cold Canadian surface high will build eastward through the Great Lakes and OH Valley. This high will ridge southward into central NC, resulting in a CAD wedge setting up over the area, which will hold through Saturday night and in some places (i.e. the northwest) through Sunday/Sunday night. With the CAD in place, temperatures will be slightly below normal, highs in the upper 40s north to mid 50s south and lows in the upper 20s north to mid 30s south. There will likely be a large temperature spread across the area from NW to SE on Sunday, with highs ranging from upper 40s to upper 50s.

Sunday night through Thursday: As the surface high moves away from the Northeast US, the Gulf low will weaken and move inland. Meanwhile, the strengthening easterly return flow impinging upon the wedge will amplify an inverted trough along the Southeast and mid- Atlantic coasts Sunday night. Warm, moist air will advect into the region and isentropic lift will result in increased cloudiness and rain chances Sunday night/Monday. The remnants of the Gulf low will increase moisture advection from the west as the associated weak s/w aloft swings through the region. Aloft, the upper trough out west will deepen as it swings through the Intermountain West and Plains Sunday night/Monday. A surface low and strong cold front will develop over the Plains/Midwest in response to the aforementioned upper trough Monday/Monday night. While some aspects of this system are still in question, this front is expected to surge east- southeast and move through the area by the middle of next week as the surface low races off to northeast into the western/central Great Lakes. Temperatures will moderate ahead of the front, especially in the east where highs could approach 70 degrees on Tuesday. Fropa should occur in the Tuesday/Wednesday time frame, with a return to cool (below normal), dry weather in its wake.

AVIATION /18Z THURSDAY THROUGH TUESDAY/. As of 640 PM Thursday .

Confidence is high that VFR conditions will dominate central NC through early Fri afternoon. Skies will be generally clear through this evening, then high clouds will overspread the area from the west later tonight, continuing into Fri morning/afternoon with steadily thickening and lowering cigs, although they should remain VFR through the 24 hr period. Winds will have a southerly component through the night, although very light, and will pick up to 5-10 kt during the afternoon. Cannot rule out some drizzle or a light shower at KFAY during the late afternoon, but have only included a VCSH mention at this time.

Starting late Fri night through Sat, behind a passing cold front, there is a slight chance of sub-VFR cigs as cool and stable air builds in from the N. VFR conditions should resume by late Sat, persisting through Sun. We'll then move into a more unsettled pattern, with a chance for sub-VFR conditions and increasing rain chances from late Sun through Tue.

RAH WATCHES/WARNINGS/ADVISORIES. None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
