AREA FORECAST DISCUSSION National Weather Service Raleigh NC 732 AM EDT Sat Jun 12 2021

SYNOPSIS. A cold front trailing an area of low pressure along the southern middle Atlantic coast will move south across central and southern NC this morning. Following north northeasterly flow and weak high pressure will result in cooler and cloudy or mostly so conditions through early Sunday.

NEAR TERM /THROUGH TONIGHT/. As of 350 AM Saturday .

A positive tilt mid and upper-level trough over the OH and TN Valleys this morning will move ewd across the cntl Appalachians today and the srn middle Atlantic and Carolinas tonight - slower by about 6-12 hrs than indicated by model guidance last night.

At the surface, a cold front analyzed at 08Z from the nrn Outer Banks (near MQI) wwd across cntl NC from near PGV to EXX will continue to move swd across the remainder of cntl and srn NC through late this morning, then across SC through the afternoon and evening. Following weak high pressure and nly to nely flow will build swd across the srn middle Atlantic and Carolinas through tonight.

Weak post-frontal low level cold air advection, and the associated development of a weak frontal inversion (~1500-2000 ft AGL), will trap low level moisture and associated overcast now expanding from VA swd across cntl NC, such that cloudy or mostly so conditions will prevail through most of the day. Nonetheless, some scattering and erosion of the low overcast will be possible around the edges, especially around the srn and wrn periphery from the srn Coastal Plain and Sandhills nwwd across the srn and wrn Piedmont by mid afternoon. It will be those areas where scattered showers and isolated storms are expected this afternoon, and where temperatures are most likely to warm into the upr 70s to lwr or mid 80s. It should remain mainly dry, cloudy, and cooler otherwise and elsewhere, with temperatures mainly in the lwr to mid 70s. Any afternoon to early evening clearing will result in pockets of radiational cooling there early tonight, such that areas of fog -- some possibly dense-- and low overcast will be likely to (re)develop, with lows in the 60s.

SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/. As of 405 AM Saturday .

A positive tilt mid and upper-level trough over cntl NC at the start of the period will drift ewd and weaken during the day Sun, while a series of stronger, progressive shortwave troughs amplify a longwave trough over the Great Lakes.

At the surface, weak high pressure extending down the middle Atlantic coast and across the Carolinas will drift toward the NC coast through Sun night, downstream of a cold front (related to the amplifying Great Lakes trough noted above) forecast to crest the cntl Appalachians and be on the doorstep of the nw NC Piedmont by 12Z Mon.

Lingering low level moisture/cloudiness early Sunday will lift and mix out through early afternoon, with noticeably lower humidity levels courtesy of surface dewpoints likely to decrease into the 60- 65 F range by afternoon. As such, forecast high temperatures mostly in the mid to upper 80s will not feel as oppressive as they have for the past week. Isolated to widely scattered convection may drift from the Blue Ridge sewd into the nw NC Piedmont by late afternoon- early evening, but it should otherwise remain dry, with lows again in the 60s.

LONG TERM /MONDAY THROUGH FRIDAY/. As of 335 AM Saturday .

Upper level pattern through the forecast period: Central NC will generally be situated between high pressure to the southeast (over the north-central Atlantic) and another high that will sit over the Four Corners through the end of next week. Relatively low pressure will persist over the East Coast, though amplification of the upper trough into the region will vary.

Monday: As the shortwave over the mid-Atlantic coast lifts to the northeast, another shortwave will dive south through the Great Lakes and mid-Atlantic, amplifying the parent trough as it does so. At the surface, a pre-frontal surface trough will develop east of the Appalachians, increasing warm southwesterly flow into the area. The cold front will approach from the northwest, moving into the area late Monday into Monday night. A surface low is expected to develop along the front as it moves through the area, coincident with the passage of the upper level shortwave. Still expect showers and storms over the area through Monday night. Highs in the upper 80s to low 90s and lows ranging from mid 60s to low 70s expected.

Tuesday through Friday: The front may stall out over or just south of the area on Tuesday, which could provide additional focus for convection, especially across the south and east on Tuesday. High pressure will build into the area Tuesday night, though the extent of which will depend on the stalled boundary, which for now is expected to move through the area by Wednesday morning. Cooler, drier weather is expected with the high pressure in place, though the greatest uncertainty with both temperature and weather will be along the SC/NC border on Thursday. The high amplitude, meridional flow aloft will persist through Thursday, with the trough remaining over the eastern US. As the upper trough shifts east Thursday night and the high over the Southwest weakens, a transient ridge will extend into the region before the next upper trough approaches on Friday/Friday night. Also of note (and keeping in mind a good deal of uncertainty at this time) will be keeping an eye on a tropical low over the Gulf and if/how it may impact the weather across the Southeast next weekend.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. As of 730 AM Saturday .

Widespread LIFR-IFR ceilings and patchy MVFR visibility restrictions will continue to develop and expand swd across cntl NC this morning, in nly to nely low level flow behind a cold front now moving through srn NC. Associated moisture will become trapped beneath a weak (frontal) temperature inversion around 1500 ft AGL today, such that ceilings will lift above 1000 ft by late morning to midday at all TAF sites except perhaps RWI, but remain in MVFR range through most of the day. Some scattering and erosion of the low overcast will be possible around the edges, especially the srn and wrn periphery from FAY nwwd to the INT and GSO. It will be those areas where scattered showers and isolated storms will also be possible this afternoon, but with a probability of occurrence too low to include in the TAFs at this time. Any such scattering to VFR late this afternoon into this evening will likely be followed by the redevelopment of low overcast and/or fog tonight. However, a pocket of low level dry air now along and offshore the nrn middle Atlantic coast will advect swwd and into cntl NC late tonight early Sunday; and that may serve to eradicate the low clouds and fog by the end of the 12Z TAF period, particularly from RWI swwd to RDU and FAY.

Outlook: Ceilings will rise through MVFR range and scatter through midday Sun, with just a small, following chance of an afternoon- evening thunderstorm with gusty surface winds at INT/GSO.
