KEY MESSAGES
1) Above-normal temperatures return today, with even hotter weather likely next week. No measurable rain is forecast over the next seven days.
DISCUSSION
KEY MESSAGE 1... Above-normal temperatures return today, with even hotter weather likely next week. No measurable rain is forecast over the next seven days.
Surface high pressure and ridging aloft will result in an increasingly warm and humid weather pattern into next week.
Expect a slight cool down on Sunday with highs in the 70s near the coast and low 80s inland on Sunday as a backdoor cold front nudges into the area. Thereafter, a warming trend ensues with surface high pressure offshore and upper-level ridging resulting in well-above normal temperatures. Mid-upper 80s will be common away from the coast with low 90s possible well-inland, nearing record temps during mid-late week at Florence and Lumberton.
AVIATION /18Z SATURDAY THROUGH THURSDAY/
Mostly VFR through the 18Z TAF period. Light and variable winds inland, while a seabreeze at the coast will veer the winds to the ESE here within the next hour or two. Dry front moves in tonight, and may try to bring in a few clouds at 5000-7000 ft, but confidence is low. Can't rule out some brief MVFR fog inland heading towards sunrise Sunday morning, but that doesn't look too favorable either.
Weak frontal boundary is offshore by Sunday morning, allowing winds to veer to the southeast and increase up to 10 kts near the end of the TAF period.
Extended Forecast...Predominantly VFR. High pressure to dominate during the upcoming work week.
MARINE
Through Sunday...Southwesterly winds at 10 kts will continue this afternoon ahead of a dry front heading in from the north. Front will move through the waters tonight, allowing the winds to back to the ESE. Seas remain locked in at 2-3 ft, perhaps some 4 ft waves out 20 nm from shore from Cape Fear to Surf City.
Sunday night through Wednesday night... As the backdoor front lifts away, expect southeasterly winds on Sunday night to veer to southerly on Monday. As high pressure shifts offshore early in the week, expect south to southwesterly flow to prevail with speeds varying between 5-15 kts, with nearshore gustiness likely due to the sea breeze.
Seas in the 2-4 ft range this weekend will subside to 2-3 ft from Monday onward. The primary contributor to the wave spectrum will remain east to southeasterly swells with a period around 9-10 sec while southerly wind waves become more noticeable starting on Monday in the 1-2 ft range.
