Area Forecast Discussion National Weather Service Wilmington NC 359 PM EDT Thu Jul 29 2021

SYNOPSIS. A warming trend continues into Friday as an upper ridge builds over the area, and a Heat Advisory has been issued over the entire area for Friday. A front will drop into the region Friday night, stalling along the coast this weekend through next week, bringing rounds of showers and periodic thunderstorms.

NEAR TERM /THROUGH FRIDAY NIGHT/. After a mostly clear night with lows in the mid 70s, the main weather concern in the near-term becomes the heat on Friday. A broad 500 mb ridge will extend from the Pacific Northwest, across the central plains, and into the mid-south states. Unseasonably warm air associated with these height anomalies will advect into the forecast area Friday afternoon on southwest winds ahead of a cold front. High temperature will reach the upper 90s, and although dewpoints will mix out into the lower 70s west of the sea breeze, this will still yield heat index values of 105-109, which will necessitate the issuance of a Heat Advisory. An afternoon sea breeze will knock temperatures down into the lower 90s close to the coast, but the net effect on heat indices will be minimal, as dewpoints in the marine layer will surge into the upper 70s.

Scattered thunderstorms are expected to develop Friday afternoon along and ahead of the cold front, and begin to impact our western counties as early as 19-20Z. This activity will push east through the late afternoon and likely linger into the evening in a moderately unstable airmass. Some of these storms may become strong to severe, with damaging wind gusts the primary threat. Areas generally along and north of a line from Florence to Shallotte to Southport are included in a marginal threat for severe weather in the Day 2 convective outlook.

SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/. Saturday starts off mainly dry before possible aftn shras/tstms especially near the coast due to the sea breeze. PoPs up to 40% along the coast and down to 20% far NW areas. High temps in the low/mid 90s, with heat indices around 105 over SW areas where another Heat Advisory may be necessary. Low rain chances continue into Sat night with a weak frontal boundary over the area and a slight uptick in deep-layer moisture. Low temps in the mid 70s most areas.

LONG TERM /SUNDAY THROUGH THURSDAY/. Long Term period will feature frequent high rain chances and slightly below normal temps on average due to the rain/cloud cover. Exception will be Sun when the combined heat and humidity will lead to another Heat Advisory possibly over the entire area. Best chance of rain will be Mon and Tue (80% PoPs most areas) as an upr-level trough takes stage over the eastern CONUS with a persistent low-level frontal boundary draped across the area providing additional forcing for ascent. Moderate to heavy rain possible as well at times next week.

AVIATION /19Z THURSDAY THROUGH TUESDAY/. VFR through the 18Z TAF period. This morning's fog near KFLO and KLBT was indeed pesky, as it eventually lifted to a low stratus deck, and is now transitioning into a stratocumulus deck. KFLO still has some lingering MVFR ceilings, but that will eventually give way to a VFR deck as the afternoon continues. Elsewhere, the seabreeze has initiated and has mostly moved past KCRE and KMYR, but some stratocumulus may straggle behind here and there.

Winds out of the SSE veer to the SW tonight. Ground retains plenty of moisture, but think it'll be just a bit too breezy for fog tonight. Coastal terminals get more of a southerly wind towards the end of the TAF period, due to the seabreeze.

Extended Outlook . VFR expected Fri with return of possible MVFR with another front into the weekend and early next week.

MARINE. Through Friday Night: A weak surface trough inland combined with Bermuda high pressure will produce 10-15 kt southerly winds over the waters tonight into Friday. Surface pressure falls over the interior Carolinas on Friday ahead of a cold front will tighten the gradient, and SW winds will increase to 20 kt, with gusts to 25 kt. Will go ahead with a Small Craft Advisory all waters beginning at noon Friday. Seas will be predominantly composed of a 4-5 second SW wind wave that will build from 2 ft this evening to 3-4 ft on Friday.

Saturday Through Tuesday: Sub-SCA conditions expected this weekend into early next week. Main story through the period will be frequent chances for shras/tstms, as a frontal boundary remains just inland allowing for S/SW flow to continue over the local waters. Winds mainly 10-15 kt, but up to 20 kt at times especially late in the day. Seas mainly 2-4 ft, up to 5 ft out 20nm on occasional at times as wind waves pick up. A weak ESE swell will persist as well into early next week.
