Area Forecast Discussion National Weather Service Charleston SC 130 PM EDT Wed Jun 5 2019 .SYNOPSIS... High pressure will remain anchored offshore through late week while a surface trough lingers over Georgia and the Carolinas. A series of upper level disturbances are expected to result in periods of unsettled weather this weekend into early next week. && .NEAR TERM /THROUGH TONIGHT/... As of 130 PM: SPC now has most of our area under a Slight Risk due to increasing instability. We're updating the forecast to reflect this along with the latest synoptic models and CAM data. An inverted sfc trough / seabreeze will develop over the Coastal Plain this afternoon. Instability is forecast to build to 2000-2500 J/kg during the mid to late afternoon, supported by dewpoints in the low 70s and highs in the upper 80s to low 90s. Forecast soundings indicate that the LFC will exist below 4 kft. As a result, it appears that scattered to numerous thunderstorms will develop within the sfc trough from mid afternoon into early this evening. Once the storms develop, steering flow should result in slow moving ESE storm motions. As the storms move east, across the seabreeze, the storms should gradually weaken. Given the slow storm motions and PW values around 1.75 inches, I suspect that a few inland locations will see rainfall amounts around 2 inches by this evening. It is possible that the strongest updrafts could produce small hail. Tonight: Thunderstorms will generally dissipate during the late evening hours. Isolated showers and thunderstorms are expected to linger through the overnight hours. Low temperatures will be complicated by rain-cooled pockets. However, generally expecting low temperatures to range from the low 70s inland to the mid 70s along the coast. && .SHORT TERM /THURSDAY THROUGH SATURDAY/... Thursday: Models over the past few runs have been flatter with mid level ridging with more zonal upper flow, likely apt for weak disturbances to pass through GA and the Carolinas. The stronger of these short waves looks timed into areas to the west of I-95 later in the day. Deep moisture and broad low-level moisture convergence along the sea breeze and inland surface trough corridors will be in place for another round of showers and tstms, mainly afternoon and evening. Instability looks less impressive, probably tempered by fairly widespread clouds and warm temps aloft. We could see some heavy downpours with these storms, otherwise severe weather potential looks marginal at worst. Friday and Saturday: A complex storm system with a cut-off mid level low pressure area will drift east from Arkansas to the upper Gulf Coast and Big South region by Saturday. This will signal the start of a significant pattern change for our area. Mid and upper flow over the region will gradually back during this period as tropical moisture from the Gulf of Mexico is shunted north and east over GA and SC. Plenty of cloud cover and periods of showers and tstms are on tap with timing a bit uncertain, still likely diurnally driven for the most part on Friday. We have boosted POPs to likely all areas for both days as confidence in wet weather increases. Locally heavy rain could occur dependent on the mesoscale, severe weather risk mainly lower end. A backdoor front should enter into the mix on Saturday but the GFS and ECMWF continue to disagree on it's eventual location in the Carolinas. Temps will be held down by more clouds, we lowered some high temps a bit per latest guidance. && .LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/... Confidence in an extended bout of well above climo rain chances continues to grow this period. A complex low pressure system will move through the Lower Gulf Coast region, pumping plenty of deep moisture into our forecast area. It looks like the entire region will get in on episodes of soaking convective rains with several inches of rain likely and much higher localized amounts a good bet sometime before the system exits sometime prior to mid week. Widespread clouds should keep highs in the mid/upper 80s each day. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... 18Z TAFs: VFR early. Showers and thunderstorms are expected this afternoon and evening. We have TEMPO groups in for both TAF sites during the time periods with the greatest potential impacts. We're only going MVFR in those groups, but wouldn't be surprised if brief IFR is possible. We'll amend as necessary. The convection will wind down late this evening, allowing for VFR to prevail. Extended Aviation Outlook: Flight restrictions are possible due to afternoon/evening showers and thunderstorms each day. Greatest chances of prolonged flight restrictions should occur this weekend when showers and tstms become more numerous over the coastal corridor. && .MARINE... A broad area of low pressure will linger across the Coastal Plain of SC and GA today into tonight. Sfc winds will remain from the south between 10-15 kts, with gusts around 20 kts this afternoon. Thunderstorms are forecast to range from scattered near the coast to isolated across the outer waters this afternoon into tonight. Wave heights are forecast to range from 2-4 feet. Thursday through Sunday: A southerly component should prevail through late week as the waters remain along the western edge of high pressure becoming centered over the western Atlantic. Winds will mainly remain 15 kt or less with seas no higher than 2-3 ft. Surface winds may back more onshore for a period this weekend as a storm system to the west begins to influence the region. The gradient could also strengthen over the weekend into early next week, however models continue to differ on the surface pattern during this time period. It appears convection will result in localized turbulent conditions at times, especially over the weekend into early next week when coverage of showers and tstms peak. && .TIDES/COASTAL FLOODING... The combination of astronomical influences on onshore winds will lead to elevated tides. Minor coastal flooding will be possible with the evening high tides through late this week, mainly for the SC coast. && .EQUIPMENT... WFO Charleston SC will only conduct upper-air soundings at 12Z until further notice due to a shortage of helium. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None.
