Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. Weak high pressure will prevail across the waters through Sunday while a large ocean low well off the mid-atlantic coast, moves farther offshore. Long period back-swells from this low will peak this weekend. High pressure will drop off the southeast coast early next week, bringing sw winds. Low pressure passing north of the waters will bring moderate west winds Wednesday and Thursday.

Area Forecast Discussion National Weather Service Wilmington NC 804 PM EDT Sat Apr 4 2020

SYNOPSIS. High pressure will build in from the north over the weekend before moving offshore on Monday, leading to a warmup. A few showers may pop up Tuesday and Wednesday. Rain will also be possible Friday and Saturday as a cold front approaches.

UPDATE/.

A 'coastal flood advisory' was needed for the lower Cape Fear River for early Sunday morning, as tidal levels are expected to exceed minor flooding benchmarks by several inches. Impacts will be minimal.

No significant edits needed with early evening updates. Dewpoints slowly ascend overnight while 10-meter winds hold steady at 5 knots. Ensemble spread of 2-meter RH shows 80-95% throughout the interior after 9z/5am, so patches of ground fog probable in spots. Observed dewpoints also bumped up this afternoon over the coastal interior, on the ocean side of the sea breeze front, and this pool of slightly higher absolute humidity could foster pockets of dense fog late.

NEAR TERM /THROUGH SUNDAY NIGHT/. Overall . expect fair weather through the near term period. There could be a few more mid and high clouds over southern areas than northern areas tonight as moisture moves through in the southern stream aloft. We could then see an increase in clouds northern areas Sunday night as a front approaches from the north. Look for mins tonight in the mid 40s to around 50 with maxes Sunday in the low to mid 70s. Mins Sunday night will fall to the low to mid 50s.

SHORT TERM /MONDAY THROUGH MONDAY NIGHT/. high pressure moves off the coast on Monday allowing for a warming return flow. A weak surface trough drifts into the area from the northwest and it appears to enhance convergence along the sea breeze as model QPF appears concentrated along the coast. Have tweaked POPs accordingly. Most places away from the immediate coast will have a high close to 80. Forecast soundings show just enough instability that isolated thunder has been added.

LONG TERM /TUESDAY THROUGH SATURDAY/. Surface forcing appears to weaken on Tuesday but stronger mid level impulses will keep POPs in the forecast on Tuesday. Piedmont trough forms on Wednesday but interestingly guidance remains rain-free as will our forecast. The decrease in cloud cover will bolster the warmth. Rain chances return Thursday and Friday as a cold front approaches slowly. The timing of this boundary is not well agreed upon between various models making it difficult to ascertain both the best rain chances and when the area dries out following FROPA.

AVIATION /00Z SUNDAY THROUGH THURSDAY/. Very fine flight conditions this TAF cycle as VFR and easy winds are anticipated. The only exception may be shallow ground fog oozing onto a few tarmacs prior to daybreak, KCRE might be slightly favored 9z-11z. This should not pose much problem due to isolated coverage and limited depth. NE-VRBL winds 4 kt or less, til 18z or so, then return flow brings SE winds at the coast and SSW winds over interior airfields, generally 5-8 kts, with VFR through end of TAF period.

Extended Outlook . Flight restrictions are possible early to mid next week with increasing rain chances from a weak system moving through. Flight restrictions lift toward the end of the week.

MARINE. Light E to NE winds this evening will gradually become S to SE by Sunday night. Speeds will remain less than 15 KT through Sun. At night and seas will generally run 2 to 4 FT through then. Periods at or above 10 seconds could result in steep waves at inlet entrances, especially during a falling tide.

Southwesterly flow on Monday as high pressure moves off the coast where it will remain on Tuesday. Wednesday will see this high move further out to sea bringing more of a westerly flow. Seas will run 3- 4 ft early in the period and should get reduced by about a foot with the Wednesday veer.

ILM WATCHES/WARNINGS/ADVISORIES. SC . None. NC . Coastal Flood Advisory from 7 AM to 9 AM EDT Sunday for NCZ107. MARINE . None.

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