Area Forecast Discussion National Weather Service Newport/Morehead City NC 459 AM EDT Thu Apr 22 2021

SYNOPSIS. A strong cold front will move offshore early this evening. High pressure will build in from the west Thursday and Friday. Low pressure will impact the region later Saturday into Sunday, followed by high pressure early next week.

NEAR TERM /THROUGH TODAY/. As of 4 AM Thu . Blustery springtime conditions continue early this morning as cooler high pressure pushes in from the west behind a departing cold front. Lingering clouds over the OBX will continue to clear through sunrise.

Downsloping low to mid level flow will keep dry conditions in place today, as continued CAA brings temps well below normal. The upper level trough axis moving overhead could bring some low to mid level clouds this afternoon, but mainly sunny skies on tap. Winds will become gusty again this afternoon, and RH values dipping down to the lower 20s% for much of the area justifies another Fire Danger Statement for this afternoon given that fuel moisture remains low. See the FIRE WEATHER section for more information.

SHORT TERM /TONIGHT/. As of 4 AM Thu . Dry conditions continue overnight as the gradient continues to gradually relax. Inland areas will likely decouple overnight as skies remain mostly clear, and efficient radiation cooling will occur within the chilly and dry airmass already in place. Patchy frost is likely inland, and could occur across much of the area not immediately adjacent to the water if decoupling occurs earlier in the night. A Frost Advisory will likely be needed.

Additionally, a few areas could challenge record lows. See the CLIMATE section for more info.

LONG TERM /FRIDAY THROUGH WEDNESDAY/. As of 430 AM Thursday . High pressure slides offshore Friday with a strong low pressure area lifting NW of the are Saturday night followed by a strong cold front Sunday. High pressure builds back in early to middle part of next week.

Friday and Friday night . High pressure migrates offshore Friday with return flow bringing warming temps with highs expected in the upper 60s to around 70 inland with coastal sections in the mid 60s. Continues dry Friday night but will see increasing clouds in advance of a system pushing across the deep south.

Saturday through Sunday . A robust mid-level shortwave and attendant sfc low track across the southern states Saturday then deepens as it tracks through the southern mid-Atlantic Saturday night. Much better moisture transport will surge into the area bringing widespread rainfall. Guidance backing off on QPF amounts some with generally 1/2 to 1 inch possible. Significant shear will be in place with guidance showing 50-70 kt 0-6km bulk shear but instability will be very limited with MLCAPE only peaking around 500 J/Kg Saturday night as the low tracks NW of the area with will serve to limit the overall severe threat, however SPC does have ENC outlooked for a Marginal Risk of severe storms as a few storms could become severe if the instability is realized. A few lingering showers possible early Sunday but the low will quickly lift away from the area with clearing skies. High temps Saturday will be in the mid to upper 60s warm into the low to mid 70s Sunday.

Monday through Wednesday . High pressure will build into the area early to middle part of next week with strong ridging aloft bringing dry conditions and a warming trend with 70s to around 80 by Tuesday and mid 80s inland on Wednesday.

AVIATION /06Z THURSDAY THROUGH MONDAY/. Short Term /through Tonight/ . As of 2 AM Thu . Gusty post-frontal NNW winds continue through sunrise under clear skies. This could create crosswind impacts for all terminals. The gradient relaxes after sunrise, but W/WNW downsloping flow will become gusty again in the afternoon/evening. Mainly clear skies with some mid/high clouds mainly north of the terminals. Very dry air will limit the fog threat tonight.

Long Term /Friday through Monday/ . As of 430 AM Thursday . Pred VFR conditions expected into Saturday morning. A strengthening low pressure center will impact the area later Saturday and Saturday night with sub-VFR conditions likely with gusty S to SE winds. Skies clear quickly Sunday with VFR conditions returning however, gusty NW winds continue behind the departing low. VFR with lighter winds expected Monday.

MARINE. Short Term /through Tonight/ . As of 4 AM Wed . Hazardous marine conditions early this morning as CAA is resulting in gusty winds mixing across all waters, with gusts to 25-30 kt. The gradient will relax some before sunrise, with gusty winds subsiding a bit for the morning hours. However, offshore flow will increase again this afternoon, with 20-25 kt gusts possible for most area waterways exposed to the NW winds. Gust frequency expected to be too low to justify extending SCAs through this evening, but mariners should be prepared for gusty winds at times through the day. Winds subside more quickly overnight as high pressure becomes more dominate.

Seas remain elevated this morning in mainly local windswell, with buoys reading 6-8 ft east of the OBX. Seas gradually subside with the wind, with SCAs for coastal zones more sheltered from Nrly windswell coming down this morning, but SCAs for zones near and north of Cape Hatteras continuing into Midday/early afternoon. Seas subside to 2-4 ft this evening and overnight as the windswell responds to the diminishing winds.

Long Term /Friday through Monday/ . As of 430 AM Thursday . High pressure will dominate Friday bringing good boating conditions but a strong low pressure area will approach the area Saturday and lift NW of the area Saturday night and expect a period of strong SCA conditions to develop Saturday afternoon with a period of Gales possible Saturday night with seas peaking around 7-10 ft. Slow improve expected Sunday and Sunday night. Lingering 6 ft seas may continue to bring SCA conditions into Monday morning across the northern and central waters.

FIRE WEATHER. As of 4 AM Wed . Gusty NW winds continue today, with a very dry airmass now in place bringing RH values to 20-25% this afternoon. This, combined with still low fuel moisture values, means that there is once again an increased fire danger today. A Fire Danger Statement is in effect today into this evening.
