Area Forecast Discussion National Weather Service Wilmington NC 1150 AM EDT Fri Apr 3 2020

SYNOPSIS. High pressure will build in from the north today into the weekend. A warmup will begin next week as this high shifts offshore. A weak cold front may reach the area midweek.

UPDATE/. No major edits are needed to the current forecast. SC forestry has issued a red flag fire 'alert, discouraging residents from conducting outdoor burns today, due to dry and breezy weather. 10-meter winds should peak at 12-14 mph through mid afternoon, with a decrease to around 7 knots by 8 pm. Max-RH to remain low as well in upcoming mornings, removing fog concerns.

NEAR TERM /THROUGH SATURDAY/. Dry weather and mainly clear through the near term period with temps near normal . highs in the low/mid 70s both days with lows tonight in the mid/upr 40s. Main item of note is relative humidity dipping to 24-29 percent most areas this afternoon, co-joined with gusty NW winds. This brings an elevated fire danger, and even though the ground remains soggy in spots, fine fuels and grasses will become capable of fire spread, as they are quick to dry.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/. Weak high pressure over the area through the latter half of the weekend. Light northerly flow will begin to veer around becoming more on shore, although remaining weak. Minor perturbations in the mid level flow and jet running over the top of upper ridge should help to produce some clouds around at times, but overall expect a dry period with warming air mass. Temps will run near normal with overnight lows creeping up a bit as onshore flow helps moisture slowly rise. Sat night will be near 50 most places and a few degrees higher for Sun night. Sun will warm into the 70s most places. Sea breeze should keep places close to the coast a bit cooler.

LONG TERM /MONDAY THROUGH THURSDAY/. High pressure shifts off the coast on Monday leading to a warmer and increasing moist return flow. The flow aloft remains more westerly with ridge to the south and shortwaves riding by to the north. Have introduced chc of pcp back in the forecast Mon through Wed with warm temps and rising dewpoints. Should see afternoon cu develop, aided by convergence along sea breeze boundary. Models also showing some impulses aloft possibly helping out with clouds and a few shwrs during the period. May see a couple of weak fronts affect the area through mid week, but overall, expect some clouds with limited chc of convection. Decent sea breeze should develop each aftn as temps warm near or above 80 each day.

AVIATION /16Z FRIDAY THROUGH TUESDAY/. VFR through the 12Z TAF period as high pressure builds in across the area. Light winds this morning will gust up to 17-20 knots by midday, still out of the northwest. Gusts should calm down by 21- 22Z. Dry and SKC today.

Extended Outlook . Great weekend to fly, with VFR conditions throughout. Flight restrictions possible for the early to mid week portion of next week.

MARINE. No headlines necessary with this forecast package. NW winds will still be breezy today (gusts up to ~20 kt) as strong low pressure pushes farther offshore. Diminishing winds then for tonight into Sat as sfc high pressure builds in from the NW. Seas persist at 2-4 ft, which includes ENE waves 1-2 feet every 12-14 seconds, as back-swell from the offshore low sends back low amplitude ripples our way.

Weak high pressure on Sunday will shift offshore by Monday with a transition from light NE-E flow to S-SW Mon through Tues. Winds less than 10 kts on Sun will increase to 5 to 15 kts Mon through Tues, with a spike up each aftn near shore in sea breeze. Seas will be 2 to 4 ft most waters. A longer period, up to 15 second, northeast to easterly swell will diminish slowly into mid week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
