Area forecast discussion, May 31, 8:06 PM EDT, 50 minutes before
Area Forecast Discussion National Weather Service Wilmington NC Issued by National Weather Service Charleston SC 806 PM EDT Fri May 31 2019 .SYNOPSIS... A cold front will cross the region tonight, the weak low pressure will persist over the area this weekend. Then, another cold front will cross the region by Monday, followed by high pressure and drier weather with temperatures closer to normal through Tuesday. A trough of low pressure could increase the chance for showers and thunderstorms mid to late week. && .NEAR TERM /THROUGH TONIGHT/... Main concern is severe thunderstorm threat through this evening as an upper shortwave and surface cold front approach from the west and the sea breeze moves inland in an environment favorable for organized convection and strong downbursts given decent mid-level dry air, instability and shear. A Severe Thunderstorm Watch remains in effect for our NC counties until 11 PM EDT. The main hazards are damaging winds and large hail, although an isolated tornado is possible, mainly near and north of Wilmington. The front should push offshore around midnight with improving conditions afterward. Lows should range from the mid 60s inland to near 70 at the coast, still slightly above normal for this time of year. && .SHORT TERM /SATURDAY THROUGH MONDAY/... Saturday: Deep layered troughing on the southern periphery of a shortwave trough exiting the east CONUS could support isolated/scattered afternoon/evening thunderstorms especially across northern/eastern sections. While MLCapes should remain limited to the 500-1000 j/kg range, the mid level thermal trough could support isolated hail. Otherwise, high temperatures in the middle to upper 80s most locations should feel somewhat cooler as compared with the recent heat wave. Saturday night, expect low temperatures in the middle to upper 60s most areas except lower 70s on the coast. Sunday: While deep-layered troughing will persist, drier air should maintain rain-free conditions. Ahead of another approaching cold front, well-above normal for early June. Then, the next cold front should cross the region late Sunday night or early Monday. Guidance has trended drier with this front, so PoPs remain below 15 percent with no mention of precipitation. Monday: In the wake of dry cold fropa, high pressure will push drier and somewhat cooler air into the region. temperatures should only top out in the middle to upper 80s. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... High pressure should provide a dry day Tuesday featuring high temperatures in the middle 80s and nighttime lows in the 60s inland and around 70F on the coast. Then, high pressure will shift offshore. Resulting southwest flow will push more humid and somewhat warmer air into the region, and guidance depicts a surface trough developing inland. Thus, conditions should become more favorable for showers/thunderstorms mid to late week. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... Thunderstorms will impact some/all terminals with gusty winds and brief flight restrictions as a cold front advances into the region by 06z. Then, VFR conditions should prevail through the remainder of the 00z TAF period. Of note, patchy fog could develop overnight, especially at terminals which received rain, and a thunderstorm cannot be ruled out Saturday afternoon, especially at KFLO, KLBT and KILM. However, the probability of these events remain to low to justify any mention/associated flight restrictions within 00Z TAFs. Extended Outlook...Low probability for brief flight restrictions in daybreak stratus/fog at inland sites. Also, any showers or thunderstorms could produce brief flight restrictions Saturday afternoon/evening and then again Wednesday. Otherwise, mostly VFR. && .MARINE... Tonight: Southwest flow will remain elevated near Advisory range early ahead of an approaching cold front which will move through after midnight. A weaker pressure gradient late will result in lighter winds and improving conditions. Also, scattered thunderstorms could be severe this evening prior to the frontal passage. Saturday through Wednesday: Offshore winds in the wake of cold fropa will quickly give way to the sea breeze Saturday afternoon, then south/southwest winds will prevail until the next cold front passes late Sunday night or Monday. During this time, winds should remain capped at 15 knots, and seas should average 2-3 feet. Then, winds will swing into the northeast as high pressure expands south Monday through Tuesday. While we cannot rule out marginal Small Craft Advisory conditions, winds have been capped at 15-20 knots, and seas should most likely remain no higher than 3-4 feet. Late Tuesday through midweek, the high pressure will shift offshore, and winds are expected to veer through east/southeast to south. By Wednesday, south winds could average 15-20 knots, accompanied by seas of 2-4 feet. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...None. NC...None. MARINE...None. && SYNOPSIS... NEAR TERM...
