AREA FORECAST DISCUSSION National Weather Service Raleigh NC 255 PM EDT Thu Aug 22 2019 .SYNOPSIS... Bermuda high pressure will remain in control of our weather conditions into Friday. A cold front will move south across the region Friday night and Saturday, bringing a good chance of thunderstorms. The front will then bring cooler and cloudy conditions for the weekend. && .NEAR TERM /TODAY AND TONIGHT/... As of 250 PM Thursday... Plentiful sunshine throughout the morning/mid afternoon hours has allowed for ample heating and destabilization to occur across just about all of central NC. RAP analysis shows SB CAPE values ranging from 3500 J/KG (West) to 4500 J/KG (East) with additional destabilization likely over the next few hours. Convective initiation is ongoing across much of the area, especially along an old MCS outflow boundary, now progressing east of the Blue Ridge and through the Foothills. Out ahead of the primary band of storms, additional convection has fired along a remnant outflow boundary situated along/just north of the US-64 corridor across the western Piedmont, in the vicinity of the lee side trough. Convective coverage and intensity will likely increase over the next few hours, especially as the more organized band of storms progress east into the Triad region (likely between 3 - 6pm) and eventually the Triangle (4 to 8pm) before continuing into the eastern Coastal Plain. These areas, especially toward the northern Piedmont zones, will be better suited for a possible damaging wind gust threat. Here, DCAPEs range in the 1100 - 1300 with slightly lower values as you progress south. PWAT values in the 1.6 to 2.1 inch range (Higher east) will also support some very heavy rainfall embedded with these storms, keeping a low end urban and small stream flood threat active, especially with a 20 - 25kt storm motion. Storms will likely continue into the overnight hours, becoming elevated and feeding off of residual ML CAPE which should remain impressively high, especially east of the Triangle, until areas get worked over. Coverage should diminish after midnight, allowing skies to clear and patchy fog/stratus to develop, primarily in vicinity of large water bodies in areas that see appreciable rain Thursday evening. Overnight lows will settle into the lower 70s. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... As of 210 AM Thursday... Strong to severe thunderstorms expected Friday afternoon and evening. Showers and thunderstorms should be ongoing over portions WVA and VA associated with the outflows and disturbances aloft early Friday. Our region should be mainly cloud free with the exception of some very early morning stratus and some residual high cirrus. Otherwise, partly sunny skies will result in strong heating Friday. This will lead to strong heating of the very moist boundary layer that will be in place out ahead of the convection and the approaching front. As highs warm into the upper 80s to lower 90s, PW's will be 2-2.25 inches, and resultant MLCAPES should again reach over 2000 J/KG. Clusters of thunderstorms are expected to develop/spread ESE off the Blue Ridge and into the Piedmont during the day. As the front drops slowly southward toward the region late in the day and during the evening, additional convection is expected. The shear is again expected to be weak, thus wet microbursts and damaging wind gusts will be the primary hazards as these storms work through the region. Clusters of showers and thunderstorms should continue into the night as the front and outflows slowly move SE. The Southern Piedmont east to the Sandhills and SE Piedmont, Coastal Plain will have the highest POP for Friday night, with convection likely diminishing in the NW-N Piedmont overnight. Lows 65-70 north, and lower 70s south. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... As of 255 PM Thursday... Extended portion of the forecast remains relatively on-track, with uncertainty remaining high, especially early next week. Have adjusted POPs slightly upward Sun - Tue as the front lingers/drifts north and hints of some tropical/sub-tropical influences begin to appear. Models continue to trend wildly with these features, so thought it best to linger CHC/SCHC POPs into the middle of next week, with a gradual warming trend likely. Previous valid discussion... Meanwhile, it's worth noting as mentioned in the latest TWOAT, the trough of low pressure located over the central Bahamas is progged by several models, including the latest ECMWF, to lift north and merge with the aforementioned cold front remnants off the SE coast on Sunday. Fortunately these models keep any low pres development well off the coast, but should this happen, central NC may actually benefit from this pattern by way of increased N/NE flow which would advect drier air into our area from the north. On the other hand, a front that stalls closer to the immediate coast would warrant PoPs across our eastern zones for Sunday. But the trends have tended to favor the drier option. Finally, such vigorous NE flow would keep temps below normal for daytime highs. That system will exit to our NE on Monday, with mainly dry weather continuing for our area. The next short wave will then approach from the west Monday night and Tuesday, with climo or higher PoPs needed for Tuesday and perhaps into Wednesday with the passage of this short wave. && .AVIATION /17Z THURSDAY THROUGH WEDNESDAY/ ...As of 100 PM Thursday... 24 hour TAF period: VFR conditions continue to remain dominant across central NC. This trend should continue through the early portion of the afternoon/evening hours, with deteriorating conditions (periods of IFR/MVFR) possible with thunderstorm development. Timing of evening convection has been a bit difficult to pinpoint, but expecting to see a general NW to SE movement with any multicellular clusters that do form. Thus, have introduced VCTS along with TSRA tempo groups across the Triad terminals (KINT, KGSO) between 21z/5pm and 02z/10pm, with an hour or so delay as you head east. Can't rule out some isolated airmass storm development out ahead of this main line, but will account for that with amendments as needed. Any storms that do impact terminals will result in periods of reduced visibilities, ceilings, and gusty winds up to 40kts. Tonight, storm coverage diminishes from west to east, leading to steadily clearing skies. Can't rule out some patchy fog/stratus formation, especially in areas that see appreciable rainfall Thursday evening. Looking ahead: Beyond 18z/Friday through Wednesday... Showers and thunderstorms are expected to develop Friday across northern NC early in the afternoon before dispensing across the area into Friday night. Sub-VFR CIGs/VSBYs will be common with any storms that do impact terminals. A cold front is set to pass through the region Friday night into Saturday, introducing widespread SUB-VFR conditions that could linger much of the weekend, especially across the southern terminals. Can't rule out some brief breaks in the CIGs/VSBYs late Saturday/Sunday across the northern terminals, but expecting deteriorating conditions once again as the front lifts back north into the first half of next week. && .RAH WATCHES/WARNINGS/ADVISORIES...

DURHAM AND FRANKLIN COUNTIES UNTIL 330 PM EDT...
At 227 PM EDT, Doppler radar was tracking a line of strong
thunderstorms along a line extending from 6 miles south of Creedmoor
to near Pittsboro to near Asheboro. Movement was east at 5 mph.
Wind gusts up to 40 mph will be possible with these storms.
Locations impacted include...
Raleigh, Durham, Cary, Chapel Hill, Asheboro, Hillsborough,
Creedmoor, Randleman, Pittsboro and Louisburg.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Wind gusts as high as 40 mph are capable of knocking down tree limbs
and blowing around light outdoor objects.
Locally heavy rain will quickly reduce visibility and result in
ponding of water on roadways. Drivers are urged to slow down and use
extra caution to avoid hydroplaning.
If on or near Jordan Lake or Falls Lake, get out of the water and
move indoors or inside a vehicle. Remember, lightning can strike out
to 10 miles from the parent thunderstorm. If you can hear thunder,
you are close enough to be struck by lightning. Move to safe shelter
now! Do not be caught on the water in a thunderstorm.
