Area Forecast Discussion National Weather Service Wilmington NC 1018 PM EDT Wed Aug 4 2021

SYNOPSIS. Stalled front near the coast will keep area cool and cloudy through Thursday, with bulk of precipitation remaining offshore and occasional showers near the coast. Area wide rain chances return Friday night through Sunday night. Below normal temps this week increase to near normal for Sunday and early next week.

UPDATE. No big changes necessary from the ongoing forecast with this update.

NEAR TERM /THROUGH THURSDAY NIGHT/. Latest surface analysis shows an old stationary front aligned parallel to the Carolina coast, located about 40-50 nautical miles offshore. This front has steadily moved further offshore throughout the day, with showers and storms following suit. Low stratus, lingering around 1500-2500ft as of this typing, has slowly been improving, and very gradual clearing is expected tonight in a northwest to southeast fashion. Stratus might be slow to clear out along the coast by Thursday morning. Lows tonight in the upper 60s.

Upper trough axis should "bottom out" in the Deep South this evening before lifting towards the northeast through Thursday. Ahead of the main trough, some small shortwaves will traverse ahead of it, translating to weak low pressure at the surface. As was the case today, looks like most of the lift and vorticity remains offshore, and think most of the area remains dry Thursday, with some sunshine to boot. Left in a slight chance of showers and storms for the coast, where some extra energy from the shortwave and/or the seabreeze may push onshore. As the pattern slowly transitions, winds become more northeasterly throughout the day. With more sunshine, temperatures start to bounce back, with highs in the mid 80s inland and lower 80s at the coast.

Thursday night, trough continues to lift to the northeast and push offshore, and modest ridging will start to develop. Winds become more easterly overnight. Lows in the upper 60s inland with lower 70s likely closer to the coast.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. Initially mid level ridging will build in from the eastern Atlantic as a slow moving shortwave moves near the Tennessee Valley. In time the enhanced southwest flow induced by the shortwave moving more eastward will increase moisture and lift across the area. Of course a front will be lingering along the coast and this will enhance pops as well. Some guidance has backed off what was a seemingly a better forced area of convection Friday into Saturday although sufficient instability combined with the aforementioned factors warrant keeping pops high. Temperatures will be slightly below normal mostly for highs with the moisture playing a significant role.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Somewhat of an unusual mid level pattern for early August of a progressive flow seems to be shaping up for the extended period. This is leading to a relatively dry period as modest ridging builds in following the unsettled short term period. The forecast remains relatively dry for the afternoon package although I suspect moisture/pops will make an appearance in time. Temperatures will warm to at or just above climatology as the period progresses.

AVIATION /02Z THURSDAY THROUGH MONDAY/. To start off the 00Z TAF period . IFR at KILM with MVFR at the Myrtles and VFR inland. These categories may bounce around a bit tonight but for the most part should be consistent as the lwr cigs are more confined closer to the offshore frontal boundary. No precip expected, with patchy fog possible as well. Becoming VFR Thu with dry wx expected; only a slight chance of a shra.

Extended Outlook . Waves of low pressure will develop along this nearly stationary front draped across the eastern Carolinas later this week, resulting in periodic MVFR/IFR from shwrs/tstms. Early morning shallow fog may also reduce vsbys each morning this week.

MARINE. Through Thursday Night . Winds at 5-10kts from the NNE veer to the NE by Thursday and to the E by Thursday night. Seas 2-3ft along the beaches become more like 3-4ft out 20nm from shore. Main wave period lingers around 7 seconds.

Friday through Monday . Outside of a lingering northeast flow for a few hours Friday, a typical summer time pattern of south to southwest winds will be in place. Some brief distortion of the wind fields could occur in convection early in the period and sea breeze accelerations will probably occur daily as well. Significant seas are representative of weak wind fields and certainly no long period swell contribution from distant tropical entities with 2-3 feet overall.
