Area Forecast Discussion National Weather Service Wilmington NC 928 PM EST Sun Mar 7 2021

SYNOPSIS. Dry high pressure will dominate the weather through the week along with plenty of sunshine. Unseasonably cool temperatures to start the week will reach near normal by Tuesday and continue to warm to above normal through the mid to late week period. A cold front should bring an end to our sunny and warm weather late next weekend.

UPDATE. Forecast on track tonight with no updates.

NEAR TERM /THROUGH MONDAY NIGHT/. 5H s/w trof moving off the Carolina Coasts at the moment. This will accelerate the movement of low pressure offshore from the GA/SC Coasts to the well offshore Atl Waters off the NE States by Mon daybreak. With NW flow aloft, Canadian high pressure will drop to the SE, with it's 1035mb center nearly overhead come sunset Mon and temporarily hold that position during Mon night. The atm column will remain quite dry thru this period given various model progged RH time height series. This the result of the dry airmass itself combined with a NW downslope flow aloft that further scours out any moisture that makes it across the Appalachian mountains before reaching the FA. The lowest various model thickness schemes (1000- 500, 1000-850) bottom out this evening and into the overnight. Have indicated some decoupling of winds across portions of the FA tonight which will further enable Min temps to drop. Have indicated widespread 20s to lower 30s at the beaches. Mon night will be more of an excellent radiational cooling night, with winds decoupling early. Have undercut MOS mins for Mon night by several degrees. Mon highs should see the 60 degree mark broken across the majority of the FA, except NE portions of the FA, but all still below the normal mid 60s highs.

SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/. High pressure nearly overhead Tues will begin to shift farther offshore through midweek as ridge aloft builds up the Southeast coast. A minor perturbation in the mid levels will pass across the area overnight Tues into early Wed and may produce some passing mid clouds, but overall expect a dry period with plenty of sunshine. Variable winds will become more southerly by late Wed into Wed night but will remain on the light side. The dry air mass with light winds will allow for large diurnal swings. Should see decent radiational cooling overnight, but passing sfc dewpoints will rise through midweek keeping overnight lows on an upward trend. Plenty of sunshine, height rises as ridge builds aloft, and WAA will produce daytime temps above normal, into the 70s, except at the beaches. Seabreeze during aftn should keep temps cooler close to the coast.

LONG TERM /THURSDAY THROUGH SUNDAY/. Southerly return flow will continue through much of the late week period with a slow rise in dewpoints and moisture through the column. Temps will run well above normal as WAA and plenty of sunshine produce readings well into the 70s, except at the beaches. As dewpoints rise into the 50s, may see some overnight fog and some potential for sea fog as winds increase out of the SW into the weekend.

Some uncertainty arises for the weekend forecast. GFS builds stronger ridge up the east coast but ECMWF and Canadian weaken the ridge allowing for a cold front to drop south into the Carolinas Fri night into Saturday. The GFS keeps this backdoor front well north of the area leaving the weekend warm and drier, and brings cold front from the west late Sun into Sun night. For now, will introduce some potential for clouds and pcp over the latter half of the weekend. Could end up with more in the way of clouds and potential for light pcp late Sat into Sun. This could also affect the temps on Sun, potentially making for a cooler day.

AVIATION /03Z MONDAY THROUGH FRIDAY/. VFR conditions continue for the next 24 hours. Clear skies a few high level clouds and light north winds under 10kts.

Extended Outlook . VFR through at least the end of the week.

MARINE. Through Monday night . The modest NNW-NNE surge this aftn will last thru tonight, finally letting up as the center of high pressure drops to the SE, reaching the Eastern Carolinas during Mon and hanging out across the waters Mon night. Overall, winds peak in speed tonight and steadily diminish during Mon becoming variable in direction Mon aftn and night. Will identify a dominate direction in lieu of indicating VRBL in the CWF. Seas will run 2 to 4 ft, with 4 footers occurring this aftn into this evening, mainly outer waters off Cape Fear and possibly Romain. This the result of the wind driven waves from the surge combining with an underlying small easterly swell from the exiting lows.

Tuesday through Friday . Light and variable winds on Tues will start to come around as high pressure overhead migrates farther offshore through mid to late week. Seas less than 3 ft will start a slow and steady rise with a light onshore to southerly flow developing. By Thurs eve seas will be between 2 and 4 ft, with 3 to 4 ft more common by Fri into the weekend. The cool ocean temps and unseasonably warm temps will create a healthy sea breeze through much of the mid to late week period with choppier seas late aftn into early evening. May also see some patchy sea fog as the week wears on.
