Area Forecast Discussion National Weather Service Wilmington NC 1125 AM EST Wed Feb 24 2021

SYNOPSIS. Dry high pressure will dominate today into Thu. Above normal temps are expected both days, with 70s possible each day, mainly away from the immediate coasts. A dry cold front, dropping south, will stall in the vicinity of the Carolinas late Thu followed by cooler and unsettled weather conditions Fri into the upcoming weekend as weak surface lows move along it.

UPDATE. No changes made with this update. Previous forecast still on track for a warm and clear day.

NEAR TERM /THROUGH THURSDAY/. Zonal flow will develop overhead today and persist thru Thu. This will help push the sfc high and it's center off the Carolina Coasts today, and well offshore by Thu. A sfc cold front will lose much of it's moisture as it reaches the ILM CWA midday Thu and tries to further drop across the FA by sunset Thu. Dry atm column thru the period with thin jetstream cirrus today and possibly altocu and possibly stratocu Thu aftn. Forcing avbl along the cold front but just not enough moisture avbl for pcpn occurrence. Will see widespread 70s for max temps today and near 70 for highs Thu. With adjacent Atlantic SSTs only around 50, should see a resultant wind, aka sea breeze, limit the immediate coast temps in the 60-65 range today. Decent westerly flow 925-850 mb will limit the inland progression of the sea breeze today and especially on Thu. The AC/SC may limit max temps Thu, especially closer to the cold front, ie. across the ILM NC CWA. Will stay a degree or 2 higher than model MOS consensus for Thu max temps, especially across ILM SC CWA.

SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/. Broad surface high pressure moves into the Northeast, setting up a cold air damming (CAD) wedge for parts of the Southeast and the mid- Atlantic states. Clouds increase Thursday night, with lows in the low-to-mid 40s. Wedge creates a cooling trend on Friday, with overcast skies and highs only reaching the 50s. Meanwhile, a shortwave trough at 500mb works with a surface low pressure system to produce a chance of showers for Carolinas Friday night, with the best chances to the north and west. Lows in the mid-to-upper 40s.

LONG TERM /SATURDAY THROUGH TUESDAY/. Surface low located offshore of the Carolinas moves northward, carrying the wedge with it. Forecast guidance has really shot up this time, with forecast highs in the upper 60s to near 70. A series of weak low pressure systems continue through the weekend, which keeps the rain chances going, especially during the daytime. Sunday looks to be quite unseasonably warm, with highs in the low-to-mid 70s. A more robust cold front surges southward Monday, though forecast guidance diverges on the timing. The cloud cover hinders high temperatures, but still remain well above climatology. Rain chances increase due to the cold front. After frontal passage, the forecast dries out and temperatures cool back down on Tuesday, with highs near 60.

AVIATION /15Z WEDNESDAY THROUGH SUNDAY/. High confidence for VFR conditions. High pressure in control with very little moisture through the column. Unseasonably warm today, except along the immediate coast. Little to no fog expected tonight.

Extended Outlook . VFR to dominate thru late Thu with high pressure prevailing across the Carolinas. Cold front to drop south and stall across the area late Thu night into Sun with periods of MVFR/IFR possible Fri thru Sun.

MARINE. Through Thursday: Center of sfc high to move across the waters and offshore today, and further offshore Thu. Relaxed sfc pg to start today with some tightening this aftn that will likely hold well into Thu as a dry cold front drops southward. Winds and resulting seas should stay below SCA thresholds this period. Could see some gustiness to the winds, 20 kt, near shore today. This the result of a resultant wind, aka the sea breeze pushing inland. 2 factors aiding the sea breeze, daytime temps 70+ degrees over land and adjacent SSTs hovering around 50 degrees. Seas will be elevated near shore and dominated by wind driven produced short period wind waves. An underlying but small ESE-SE 8+ second period swell will persist thruout this period. For Thu, the sfc pressure pattern may yield a more synoptic SW-W direction ahead of the cold front dropping south. Have indicated the CFP reaching Cape Fear by sunset Thu with the NE surge in close proximity.

Thursday Night through Sunday: High pressure wedge in place keeps northeasterly winds at 15 kts Thursday night through Friday,with gusts up to 20-25kts possible Friday afternoon. Seas 2-3ft, increasing slightly to 2-4ft. Wedge starts to erode Friday night, as a low pressure system makes its way up the coast. Winds veer to the SSW at 10-15kts through Saturday. Seas increase to 3-5ft. Wind direction and speed remain consistent through Sunday, with seas relaxing slightly to 2-4ft.
