Area Forecast Discussion National Weather Service Newport/Morehead City NC 350 PM EDT Thu Jul 29 2021

SYNOPSIS. Offshore high pressure will continue through tonight. A weak cold front will approach Friday, lingering over the area through the weekend. A much more active period emerges early to mid next week as several waves of low pressure traverse the area.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. As of 335 PM Thurs . Sunny and warm conditions will continue this afternoon due to some slight subsidence between upper level shortwaves, and infusion of much drier air into the mid and lower levels of the atmosphere. After a slow start, still expect highs to reach the upper 80s to low 90s with full sun expected through the rest of the afternoon. With dewpoints mostly in the low 70s inland, and mid 70s along the coast, heat indices will likely reach 100-105 later this afternoon during peak heating.

Mostly quiet weather will continue tonight though southerly flow will increase this evening ahead of a slow moving cold front. A slight breeze is expected to persist inland overnight which will limit cooling to the mid to upper 70s, while a decent wind closer to the coast will keep temps very warm in the upper 70s to low 80s.

SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/. As of 340 PM Thurs . Ahead of a slow moving cold front tomorrow, low level heights will peak, and we will likely see our hottest day of the year so far. Heating will get a head start thanks to very warm lows tomorrow morning, which should allow for temps to heat into the upper 80s by late morning. The temp forecast thereafter remains tricky with a likely area of convective initiation across the coastal plain and eastward towards the Albemarle Sound, while a strong sea breeze will be mostly pinned along the coast, but will make some inland advancement through the afternoon. In between these features temps will warm into the mid to upper 90s, with dewpoints remaining in the low to possibly mid 70s. This will lead to a period of heat indices 105-110 for the coastal plain south of US 70, and for portions of the Inner Banks over to the Northern Outer Banks. A heat advisory will likely need to be issued for these counties at least. Farther north along the coastal plain thunderstorm development should limit high temps from climbing past the mid 90s, and limit the duration of heat indices over 105. Along and behind the sea breeze temps will remain cooler, however dewpoints approaching 80 will result in heat indices right around105.

The area is also under a risk for isolated severe thunderstorms tomorrow afternoon, and SPC has highlighted a marginal risk over ENC. As moisture advection increases tomorrow, and temps climb into the 90s, moderate to strong instability will develop in the afternoon as wind shear increases to 30-40 kts. This will lead to the potential for damaging wind gusts, and some large hail. Some isolated areas of flooding are also possible if the coverage of storms is sufficient, as PWATs remain above 1.75".

LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/. As of 340 PM Thu . Hot weather and the potential for severe thunderstorms highlight Friday, with a very active pattern emerging over the weekend and continuing at least into the middle of next week.

Friday Night through Sunday . Convective activity will push off the south coast Friday night as the surface front is now expected to push across most or all of the area by sunrise Saturday. However, heights aloft will begin to fall as troughing digs across the Ohio Valley toward the southern Appalachians, and the first in what will be several waves of low pressure will develop over the Southeast along the stalled boundary. This wave will bring the next round of storms Sunday as the boundary slides back over the area, where it will remain for the better part of next week. Developing deep layer moisture transport on the east side of the unseasonably high- amplitude trough will bring the potential for heavy rainfall, with the severe threat dependent on the timing and strength of the wave as it crosses the area Sunday.

Monday through mid-week . Unsettled weather continues early to middle of next week as the surface boundary remains stalled over/near the area with a relatively high amplitude upper trough over the southern Appalachians. The second significant wave traversing the boundary looks to impact the area late Monday into Tuesday, but timing is uncertain at this point. Overall, expect a wet period with persistent deep moisture advection brining flooding rainfall concerns, and periods of severe weather concerns possible as well. Temps will be near to below normal owing to cloud cover and periods of rainfall.

AVIATION /20Z THURSDAY THROUGH TUESDAY/. SHORT TERM /Through Tomorrow Afternoon/ . As of 345 PM Thurs . VFR conditions are expected through the TAF period as quiet weather continues ahead of a cold front. Just a few clouds are expected through mid morning tomorrow as much drier air remains in the low to mid levels. Thereafter, the atmosphere will moisten ahead of a cold front and clouds, and eventually scattered thunderstorms will develop across the airspace, however most of the activity will occur after 2 pm tomorrow.

LONG TERM /Friday through Tuesday/ . As of 4 AM Thu . VFR prevails through midday Friday, with increasing convective activity later in the day bringing the potential for at least temporary flight restrictions. A much more active period will emerge later Saturday through the middle of next week, with periods of heavy rainfall and erratic winds in and around thunderstorms being the primary concerns.

MARINE. SHORT TERM /Tonight and Tomorrow/ . As of 345 PM Thurs . Subpar boating conditions are expected tonight and through most of tomorrow as winds strengthen ahead of a cold front. Have Small Craft Advisories set to go into effect tonight for all the coastal waters and Pamlico, Roanoke, and Croatan Sounds.

Currently winds have increased from relatively calm this morning to 10-20 kts out of the SSW, with seas still 2-3 ft. Winds are expected to continue to strengthen tonight becoming 15-25 kts by late evening, and then continuing through most of the day tomorrow. A cold front will push southward through the afternoon, leading to improving conditions from north to south late in the day. Seas are expected to be 4-6 ft tomorrow as well.

LONG TERM /Friday Night through Tuesday/ . As of 350 PM Thu . Strong storms are possible over the waters later Friday, with frequent lightning and strong/erratic winds the primary concerns. Light to moderate NE flow prevails behind the front Sat, with seas around 3 ft bringing seasonable marine conditions. However, the front will move back over the waters later Saturday, with several waves of low pressure moving along the front for the second half of the weekend through early next week. Generally moderate NE winds N of the front, with moderate SE to SW winds S of the front, with periods of breezy conditions when the low pressure waves are over/near the area Sunday and again Monday night. Unsettled conditions early next week, with periods of increased storm activity with high lightning activity and erratic/gusty winds possible.
