SYNOPSIS
Dry high pressure will build in tonight and dominate through the weekend with a gradual warmup commencing as the high shifts off the Southeast coast Friday night. The next chance of rain will accompany a cold front late Tuesday into Wednesday.
UPDATE
No major changes were made with the latest update. Seeing some fog develop where winds have dropped off and low-level moisture remains high. However, not expecting it to last too long as drier air will be moving in and boundary layer flow should increase a bit so have not added to the forecast. Otherwise, should be a colder than normal night with lows near 40 most locales.
NEAR TERM /THROUGH FRIDAY/
Moderately strong mid level trough impinging upon the area showing up best in WV imagery while visible channel shows baroclinic leaf moving off the coast. The trough has pushed a surface front off the coast evident by this afternoon's well below climatology. So too will tonight's lows be below normal. Luckily guidance is pretty tightly clustered and there doesn't seem to be any potential for frost as temperatures remain just mild enough and we also hold on to a few knots of NW wind. Dry air will precede the cold air and skies will clear out quickly this evening. As wind turns from NW to W tomorrow the CAA will shut down tonight and then reverse to WAA Friday allowing for a return of seasonable temperatures.
SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/
For those who enjoy warm weather, conditions are shaping up for a pleasant weekend. With surface high pressure shifting off the southeast US coast on Friday night and remaining north of the Bahamas, warm southwesterly winds will usher in increasingly warm temperatures through the weekend. These warm temperatures will come courtesy of increasing 1000-500mb thicknesses and mainly sunny skies as mid-level subsidence keeps low-level cumulus at bay while some passing cirrus grace the sky on Saturday.
An initially chilly Saturday morning with lows in the mid-upper 40s is expected to see highs reach the mid- to perhaps upper 70s and somewhat milder morning lows on Sunday in the low-mid 50s are expected to rebound into the low 80s. Thicker high-level clouds are expected to move overhead on Sunday night, limiting overnight lows to the upper 50s to around 60F.
LONG TERM /MONDAY THROUGH THURSDAY/
Mid-level ridging and temperatures are still expected to peak on Monday with highs in the low-mid 80s, which would be about 10 degrees above normal for April 1st, but still about 5-10 degrees below record highs. High-level cloudiness and a considerable amount of cumulus are expected though, which could limit highs depending on their thickness and extent. In addition, those clouds will keep overnight lows well-above normal, with low to mid-60s forecast for Monday night.
Beyond Monday night, model guidance appears to be coming into better agreement on a potent shortwave trough diving down from central Canada and spinning up a closed low over the Great Lakes on Wednesday. This will cause surface low pressure to strengthen as it crosses New England, bringing a better shot of cool/dry air behind its associated cold front. This front is still expected to approach during the midweek period, but the daylight hours on Tuesday should stay dry while rain chances increase over Tuesday night. A band of showers associated with the front should cross the area from Tuesday night into Wednesday with the frontal passage and dry northwest winds taking over for Wednesday night. The airmass behind this front looks to knock temperatures back to near or below- normal, with highs in the 60s and lows in the 40s.
AVIATION /02Z FRIDAY THROUGH TUESDAY/
High confidence in mainly VFR conditions through the 00Z/29 TAF period across SE NC and NE SC under building high pressure.
Expect KMYR/KCRE to become VFR by 00Z with KILM following shortly thereafter. Also, could see brief vsby restrictions as fog develops this evening but increasing boundary layer winds and drier air should prevent significant, long-lasting impacts.
Otherwise, winds will increase from the west Friday with gusts near 20 kt at times, especially in the afternoon.
Extended Outlook...VFR.
MARINE
Through Friday...
High pressure building behind this morning's cold frontal passage. The tight gradient will keep winds and seas in SCA realm through the evening and into the first part of tonight.
Both should drop below thresholds later tonight and the 08Z expiration time for the headline still appears to be on track.
As the center of the high draws closer from the west as Friday progresses local winds will veer to W and continue to abate.
Seas will have trouble dropping much below the 3-5 ft range.
Friday night through Tuesday...
Initially westerly winds will back to southwesterly Friday evening and will prevail through the entire period. We will see occasional enhancements to the flow as the pressure gradient oscillates between tightening and loosening as low pressure areas pass by well to our north. Overall, winds will stay sub- SCA, although gusts may approach or reach ~25 kts at times. In addition, seas generally remain in the 2-4 ft range with some 5 foot seas possible mainly on Saturday night and again late on Tuesday. Seas will initially be a combination of 1-3 ft easterly swells at 11 sec and 2-3 ft southwesterly wind waves at 4-5 sec. The easterly swells subside to 1-2 ft by late Saturday and diminish through Sunday while the southwesterly wind waves take over as the primary contributor to wave heights with a period of around 5 sec.
