Area Forecast Discussion National Weather Service Newport/Morehead City NC 400 PM EST Tue Mar 2 2021

SYNOPSIS. Low pressure developing off the Southeast coast tonight will pass south of the area Wednesday. High pressure builds back in to round out the work week. Another offshore low could affect the area over the weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 330 PM Tue . High clouds linger this evening, inhibiting radiational cooling despite relative light winds. Then, overnight, low pressure developing off the Southeast coast will push a lower to mid level warm front toward the area. This warm front will likely reach coastal areas south of New Bern by sunrise, bringing increased cloud cover, warming temps, and the change for light rain. However, much of the area will remain north of this front, with the very dry low level airmass currently in place lingering. If skies are able to clear for a couple of hours then temps could cool quickly, and have dropped lows a couple of degrees mainly across the inner coastal plain north of Kinston.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/. As of 340 AM Tuesday . Low pressure will pass well offshore south of the area through day Wednesday. There will be a sharp gradient in low to mid level moisture across the day with this passing feature, and the primary adjustments to the forecast were to try to reflect this gradient. Rainfall is likely along the coast south of the New Bern, with QPF generally around one quarter of an inch or less. North of New Bern, low level moisture will be very limited, with little to no QPF, and more limited cloud cover. Highs are most reflective of expected sky cover, in the upper 58s along the US HWY 64/264 corridor, but mainly lower to mid 50s Crystal Coast/Jacksonville/New Bern areas.

LONG TERM /WEDNESDAY THROUGH TUESDAY/. As of 205 AM Tuesday . The overall pattern for the next 7 days is looking cool and mostly dry. The models appear to be arriving on a consensus regarding developing low pressure off the southeast coast this weekend. The trend is to keep the low suppressed south and further offshore with only small chances for light rain along the immediate coast.

Thursday through Friday . High pressure will build over the area with dry weather expected and a reinforcement of the cold temps Fri. Temps will be slightly below climo due Thu around 60, dropping much below normal on Fri with highs in the 50s.

Saturday and Sunday . Low pressure will be developing off the southeast coast this weekend. The track of this system will be critical to how much wind/precipitation impact's there will be across Eastern NC. The trend is to keep the low suppressed south and further offshore with only small chances for light rain along the immediate coast and keeping the strongest winds well offshore. Temps will be below normal with highs in the 50s.

Monday and Tuesday . High pressure is expected to build south over the area early next week producing dry/cool weather.

AVIATION /21Z TUESDAY THROUGH SUNDAY/. Short Term /Through Tonight/ . As of 1245 PM Tue . High confidence in VFR conditions through the period. High pressure continues to build over the Carolinas this afternoon keeping low level subsidence and mainly clear conditions in place. Exception is a healthy band of mid and high level clouds streaming off of developing low pressure over the northern Gulf of Mexico, which is forecast to deepen and lift off the SE coast overnight. Guidance continues to track this feature further south, lowering the odds of sub-VFR impacts. EWN/OAJ the most likely candidates for periods of MVFR cigs, although probability based on current data is AOB 30%.

NE winds this afternoon become light and variable tonight, backing to the north at 5-10 kt as low passes to our south. Despite light winds, persistent high clouds should prevent any fog formation.

Long Term /Wednesday through Sunday/ . As of 205 AM Tuesday . A low pres area moves off the coast Wed with good rain chances and sub VFR possible. High pressure builds in Thu through Sat inland with dry weather and VFR conditions.

MARINE. Short Term /Through Wednesday/ . As of 1145 PM Mon . Weak high pressure builds in from the north as low pressure develops off the Southeast coast tonight, passing offshore south of the waters Wednesday. Moderate NE to E winds prevail overnight, with mainly 3 to 5 ft seas, though some 6 ft seas remain possible 10-20 nm off Hatteras Island through early evening (SCA in effect through 9 PM).

The gradient tightens mainly south of Cape Hatteras Wednesday as the low moves eastward from the NC/SC state line. NE winds 15-20 kt with gusts to 25-30 confined to these coastal waters late morning through the afternoon, with NE winds 10-20 prevailing elsewhere. Accordingly, seas increase, to 5-7 ft mainly south of Ocracoke Inlet Wednesday, lingering into Wednesday night, with an SCA now in effect for these coastal waters. Elsewhere, 3 to 5 ft seas prevail Wednesday.

Long Term /Wednesday Night through Sunday/ . As of 205 AM Tuesday . Seas gradually subside and moderate NW winds develop Wednesday night as low pressure pulls further away from the coast. For the remainder of the forecast Thu through Sun, high pressure will build over the waters with northerly flow 10-20 kt with seas mainly 2-4 ft.

MHX WATCHES/WARNINGS/ADVISORIES. NC . None. MARINE . Small Craft Advisory until 9 PM EST this evening for AMZ152- 154. Small Craft Advisory from 10 AM Wednesday to 3 AM EST Thursday for AMZ156-158. Small Craft Advisory until 6 PM EST this evening for AMZ150.
