Area Forecast Discussion National Weather Service Newport/Morehead City NC 104 PM EST Thu Feb 20 2020

SYNOPSIS. Low pressure will develop to the southeast today then deepen and lift northeast well offshore tonight and Friday. Cold high pressure will rebuild over the area for the weekend, before another area of low pressure impacts the area early next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 1100 AM Thurs . Areas of light precip have spread out quickly across eastern NC with a few reports of brief moments of sleet mixing in for areas surrounding Hwy 264. Surface temperatures remain warm at the time, in the low 40s, so no impacts are expected from any sleet mixing in. Mesoanalysis shows an area of strong 850mb frontogenesis parked over Hwy 64 south to around Hwy 70, providing an area of enhanced shower activity with some sleet mixing in.

Temperatures have begun steadily dropping across inland areas and are expected to continue through the day. CAA will strengthen as the gradient increases between cold high pressure pinching down from the north, and a developing low pressure off the South Carolina coast. This will further decrease temperatures into the 30s by late this afternoon, with rain changing to snow as soon as 4 or 5 pm across the NW coastal plain. At first little to no accumulations are expected, as temps remain above freezing until early evening.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. As of 320 AM Thurs . Winter Storm Warnings are now in effect for much of the area, with Winter Weather Advisories continuing for the rest of Eastern NC except for Hatteras and Ocracoke Islands, as confidence has increased on a more widespread moderate snow event with snow totals of 4-6 inches expected generally north of the Neuse River and then spreading east to the Alligator River. With some mesoscale banding expected to develop in this area, locally heavier snow amounts of 6-10 inches are possible. Further to the south and east, initially warm temps both aloft and at the surface will limit snow totals as the changeover to snow will be delayed until 10 pm or midnight (There could be a few hour period of sleet along and south of US 70 early tonight). Still amounts of 1-2 inches are expected with some locally higher amounts of 2-4 inches possible.

Snow will be heaviest from midnight to 6 am across the northern half of the area, and then heaviest from 6 to 9 am across the southern and eastern NC coasts. Precip looks to linger a bit longer as well, with chances for rain/snow through mid morning. Whiteout conditions will be possible along and near the coast as winds gust to 30-40 mph, and could be enough to cause isolated power outages with heavy, sticky, snow clinging to trees and power lines.

On a different note, rain will be moderate to heavy at times before the changeover along the coast, with 1 to 2 inches expected, which could lead to some minor flooding issues in poor drainage areas.

Behind this system Friday skies will clear from west to east, but strong winds will continue. Strong CAA and snow cover will limit surface heating, and temperatures will struggle to reach past the upper 30s, with wind chills in the 20s all day.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. As of 245 AM Thu . High pres will build in Fri night thru the weekend with dry weather. With expected snow pack and clear skies Fri night expect very cold temps with cooler inland areas dropping to around 20. Beaches will be a bit milder with upr 20s to lower 30s. Temps remain cold Sat with highs in the 40s to around 50 with plentiful sunshine. Temps moderate on Sunday as the high builds overhead and hgts aloft increase. Highs shld reach upr 50s to lower 60s most spots.

Mon through Wednesday . Looks mild and unsettled this period as a cold front approaches Mon and slowly pushes thru Tue and Tue night before dissipating. Plenty of moisture will spread N in advance of the front with likely pops Mon/Mon night and chc Tue. May see bit of break in shra Wed but kept low chc pops in with dissipating front just off the coast. Highs Mon will be mainly in the lower 60s with mid/upr 60s Tue and Wed.

AVIATION /18Z THURSDAY THROUGH TUESDAY/. Short Term /through Friday morning/ . As of 1250 PM Thu . Precip shield can be seen covering most of the TAF sites and conditions are expected to deteriorate from here. VFR conditions will switch to MVFR within the next few hours as the coastal low continues to strengthen this afternoon. Late afternoon/early evening is when we will begin to see ceilings drop as rain begins to change over to a wintry mix, bringing with it IFR conditions. Tonight into the overnight hours, precip will transition to all snow beginning NW and pushing SE, dropping visibilities down to 1 mile, or potentially less. Ceilings and visibilities will improve once the snow tapers off W to E Friday morning. Strong NNE winds will persist throughout the TAF period.

Long Term /Fri Through Monday/ . As of 1215 AM Thu . Bulk of precip will be east of taf sites by 12Z Fri with ceilings grad improving to VFR. N winds will remain gusty Fri. VFR conditions expected to prevail through the weekend as high pres builds across. Shra threat increases Mon ahead of approaching cold front with sub VFR poss.

MARINE. Short Term /Today and tonight/ . As of 245 AM Thu . Dangerous boating expected as strong NNE winds develop today and cont tonight as low pres develops and deepens well to the SE. Cont Gale Warning for all but Pamlico River where have SCA. Winds will increase to 25 to 35 kt later today then increase further to 30 to 40 kts most wtrs tonight with some gusts close to 50 kts warmer outer wtrs. These winds will lead to seas reaching 6 to 9 feet late today and 9 to 14 ft tonight.

Long Term /Fri through Mon/ . As of 245 AM Thu . Strong winds cont first half of Fri with cont Gales . Winds will slowly begin to decrease later Fri as the low moves further offshore, however seas of 10 to 15 ft expected thru the day. Winds will cont to grad subside Fri night reaching 10 to 20 kts late with seas only slowly subsiding to 6 to 9 ft. Winds become light Sat as the high builds close with seas subsiding to 4 to 6 ft late. Light winds cont Sunday with the high overhead . seas finally drop below SCA lvls Sun at 3 to 5 ft. The high moves off the coast Mon with front approaching from the W. SSW winds will increase to 15 to 20 kts later Mon with seas building back to 4 to 6 ft.

TIDES/COASTAL FLOODING. As of 245 AM Thu . NNE gale force winds are expected late today into Friday, as an area of low pressure lifts east to northeastward well off the Carolina coast. These strong winds will lead to minor soundside water level rises for areas adjacent to the Southern Pamlico Sound, mainly Eastern Carteret and areas along the lower Neuse River, as well as Ocracoke and Hatteras Island south of Buxton. Minor inundation 1-2 ft (agl) are expected, and a Coastal Flood Advisory conts for these areas. A High Surf Advisory was issued for the OBX from Cape Hatteras North this evening thru late Fri night for 8 ft+ waves in surf zone.

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