Area Forecast Discussion National Weather Service Newport/Morehead City NC 713 PM EST Fri Jan 15 2021

SYNOPSIS. A cold front will cross the area tonight. High pressure regains control this weekend through middle next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. As of 700 PM Fri . A slow moving cold front will push across the region tonight, which will be felt through a band of light to medium showers which are currently moving into the coastal plain this evening. There could also be some showers that develop over the coastal waters and move onshore to the Outer Banks and Down East Carteret. The front will gain some eastward momentum tonight, and should be offshore of the Outer Banks before sunrise. Initially mild temps this evening in the 50s, will drop precipitously overnight behind the front, with temps falling into the mid to upper 30s by morning over the coastal plain, and low to mid 40s along the coast. With this rapid cooling expected right before sunrise (and wet ground), there is a good chance for some dense fog to develop along the coastal plain, which could reduce visibilities below 1 mile for a few hours around sunrise.

SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/. As of 3 PM Fri . Cold upr low will pivot across the Carolinas during the day, leading to blustery and cool weather conditions. Very steep lapse rates and unidirectional flow will produce quite gusty winds. Mixed down from 850MB suggests wind gusts easily approaching 25 kt, possibly even higher. Have retained iso rain showers as core of upr low pivots through the region with widespread strato cu. With the freezing level at only 2.5k ft or so, cannot rule out some mixed graupel falling out of the sky, but not enough to mention in grids, and certainly no impacts as sfc temps will be well into the 40s.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/. As of 315 AM Friday . High pressure will rebuild over the area Sunday with clear skies expected.

Another strong mid-level shortwave crosses the area on Monday, but the best moisture will be to our north and will keep Monday dry. Generally sunny and seasonable weather into midweek. A dry cold front crosses the region Wednesday, just a wind shift expected with this front. High temperatures will mainly be in the lower 50s with lows in the 30s, with upper 20s Tuesday morning.

By Thursday, a warm front surges north with increased low-level moisture in the Carolinas. Have low PoPs in the forecast for Thursday with temperatures moderating into the mid and upper 50s.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/. Short Term /Through Saturday Evening/ . As of 705 PM Fri . VFR conditions are present across the airspace currently, but that will soon change as a cold front enters the region, and will move across the region and offshore overnight. MVFR conditions are expected for the first half of tonight with light rain falling and ceilings coming down to below 2500 ft . there could also be some patchy fog as well. During the heaviest rainfall, conditions are likely to briefly come down to IFR, which will be late this evening to just after midnight.

After the front pushes offshore, there will not be much of an airmass change, and as skies clear, temperatures will plummet down into the 30s across the coastal plain. This set up, combined with freshly wet ground, should allow for a sizable area of fog and low stratus to develop a few hours before sunrise, and then lasting a few hours. IFR to potentially LIFR conditions are possible, with the eastward extent somewhat unknown at this time, as it depends on how quickly, and exactly where, the clouds clear out overnight. By mid morning, VFR conditions are expected to return to all locations, and will last through the rest of the day.

Long Term /Saturday night through Tuesday/ . As of 315 AM Friday . Mostly VFR conditions. VFR conditions expected Sunday through Tuesday with high pressure in control of area weather.

MARINE. Short Term /Through Sat/ . As of 3 PM Fri . An approaching cold front will deteriorate conditions through tonight, as swrly winds become gusty in the 20-30kt range for the srn/ctrl waters. Elsewhere, cold water will limit the mixing and winds should stay 10-20 kt or so through Sat morning. Behind the front on Sat, winds pick up in strength everywhere as CAA will be underway by afternoon, with gales still on tap for the srn/ctrl waters as well as Pamlico Sound. Have added the interior rivers Neuse and Pamlico to suite of SCA's, as gusty winds will easily blow above 25 kt beginning Sat afternoon and lingering through Sat evening. Seas will respond in the gales by building to as high as 7-9 ft.

Long Term /Saturday through Tuesday/ . As of 330 AM Friday . A period of gusty winds and rough seas will continue through the weekend. Westerly winds Saturday on the coastal waters and Pamlico Sound will run 20-30 knots with some gusts to 40 knots. Seas will build as high as 6-9 feet over the coastal waters during Saturday into Saturday night. Winds subside a bit on Sunday, but seas remain elevated. By Monday into early next week, westerly winds drop off to 10-20 knots with seas 3-5 feet.

MHX WATCHES/WARNINGS/ADVISORIES. NC . None. MARINE . Small Craft Advisory from 1 PM Saturday to 1 AM EST Sunday for AMZ136-137. Gale Warning from 5 PM Saturday to 1 AM EST Sunday for AMZ135.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

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