Area Forecast Discussion National Weather Service Wilmington NC 931 AM EST Mon Mar 8 2021
SYNOPSIS. Dry high pressure will result in mainly clear skies and a pronounced warming trend through the week. A cold front may approach the area next weekend.
UPDATE. Minor tweaks to dewpoints other current forecast discussion still holds.
NEAR TERM /THROUGH TUESDAY/. Freezing start but desert-like column dryness in full sun coupled with weak adiabatic compression today off the highlands, will boost temperatures 30 degrees fahrenheit or more by afternoon from first light's frigid onset. Wind plumes aloft cross-cutting mountain- ridges inducing terrain-cirrus presently, but should remain thin, not impactful on temperature curves. Although we receive SW wind flow by tonight, it will be too weak to combat the dense continental air, so early decoupling will introduce another crisp night tonight, above freezing most areas, but deep in the 30s under a clear sky dome. Another huge diurnal range Tuesday after a chilly beginning, rising well into the 60s, above normal by several degrees for March 9th with sunshine minutes racking up near maximum, H2-H4 cirri late.
SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/. The chilly nights end Tuesday night as light southerly winds will bring seasonable lows as the center of high pressure moves off the coast. The same light winds will help usher in some mild air Wednesday afternoon as most places away from the immediate coast take a run at 70. Synoptic scale flow will be light enough through the boundary layer for a sea breeze to develop as soon as temperatures warm sufficiently so a few places along the beach will have early highs. Meanwhile the southerly winds ahead of any sea breeze may keep coastal Brunswick struggling to hit 60. A shortwave crossing the area early Wednesday will have PWs of 0.4" to work with and will likely thus be hard-pressed to even be much of a cloud producer.
LONG TERM /THURSDAY THROUGH SUNDAY/. Not only will we still be having some low level return flow early in the period but mid level heights will be rising as a ridge in the Gulf gains amplitude. This will help to bolster the warmth as will the fact that the days will start with milder values as the nights grow increasingly mild. Lastly this will widen the range in highs experienced beaches vs inland as the low 50s SSTs sweep inland each afternoon; the seabreeze slightly more pinned to the coast compared to the mid week period by the offshore flow resulting from the GOMEX ridge growth. The pattern may be ready to change on Sunday. A large and slow moving cutoff in the southern branch will be heading east though likely not as fast as portrayed by any guidance. The northern branch will be developing a trough over the Great Lakes that may backdoor a front into the area. This may be too fast as well but will show some lowered temperatures and small rain chances.
AVIATION /15Z MONDAY THROUGH FRIDAY/. Skies will be nearly cloud free through the forecast period. A south southwest resultant is expected along the coast, with cooler temperatures. Light winds tonight with little or no fog expected.
MARINE. Through Tuesday . Improved marine conditions upcoming, wind easing, seas diminishing, as high pressure slips SE off land and overhead of the local waters this evening, drifting seaward through the period. NE waves will decrease in height, increase in wave period, from 4-6 seconds today to 6-7 seconds Tuesday, easing the vessel bump-factor noticeably. As the axis of said surface high moves farther SE, local winds will remain light, but take-on a SW direction by sun-up Tuesday. The atmosphere is dry so no marine weather impacts this period. Inshore water temperatures remain frigid, 52-55 degrees, but this to increase this week as atmospheric warming emerges. Rising sun-angle also increasing heat conduction in ICW/near-shore waters, climate not to be held back.
Tuesday night through Friday . As the center of high pressure moves just barely off the coast Tuesday night a light southwesterly wind becomes established. Due to the proximity of the high wind speeds will be capped in the 5-10kt range and with all long period swell remaining well to our south seas will run just 2 ft. Not much changes for the remainder of the period save for a slight continuation of the eastward progression of the high leading to a slight backing of the wind to southerly. Wind speeds and dominant wave heights will remain unchanged. Each day will grow quite mild and an active sea breeze expected and so a little choppy near some beaches and inlets.
