NWS Charleston, SC wrote its last area forecast discussion before the first event at Jul 8, 3:01 PM EST, 2 hours 41 minutes earlier.
Area Forecast Discussion National Weather Service Charleston SC 401 PM EDT Sat Jul 8 2017 .SYNOPSIS... A weak cold front will drop into the area Sunday then dissipate. The area will then remain situated between an inland trough and Bermuda high pressure for most of next week. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... This Evening and Tonight: High pressure will gradually retreat east over the western Atlantic while a weak cold front associated with a large-scale trough shifts over the Appalachian Mountains and Mid- Atlantic states, enhancing a piedmont trough inland. The setup will favor warm conditions and potentially greater coverage of showers and thunderstorms over parts of Southeast South Carolina and Southeast Georgia this evening and early tonight. Isolated showers ongoing inland will continue to struggle for the next hour or two, but should eventually expand in coverage into the evening. Weak mid- lvl lapse rates, lifted index values near -6 C, SBCAPE between 3000- 3500 J/kg, DCAPE around 1000 J/kg and PWATs up to 1.75 inches could support a few pulse/multicell type thunderstorms capable of damaging wind gusts this evening and early tonight. A lull in activity could then occur for a few hours later tonight, but weak sfc convergence and lingering instability should support a slight chance to low chances of showers and/or thunderstorms late as the sfc cold upstream gradually pushes over the Piedmont region. Chances of precip appear greatest over northern areas of Southeast South Carolina late tonight. Low temps are forecast to range in the mid to upper 70s. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/... Sunday: A series of upper shortwaves will approach from the west while a weak cold front drops into the area. It's unclear exactly how far southeast the front will move; at this point the most likely scenario is that it will stall across inland areas. Ahead of the front, moisture will pool, with Precipitable Water values rising to 2.15" across the area. Ample sunshine will push temps into the low 90s, yielding CAPEs 2000-3000 J/kg. There should be ample instability and forcing to trigger scattered to numerous showers and tstms, especially in the afternoon and evening hours. The severe thunderstorm potential may be slightly greater than a typical summertime day given a bit more 0-6 km shear than normal (15-20 kt in the afternoon). Monday and Tuesday: A broad upper trough pattern will persist across the Southeast while Bermuda high pressure tries to rebuild at the surface. A robust ribbon of 2"+ PWATs will remain overhead while the upper shortwaves and afternoon sea breezes provide ample forcing for scattered to numerous showers and tstms. High temps will be in the lower 90s. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... The forecast area will remain situated between the Bermuda High offshore and a weak Appalachian lee trough inland. For now, POPs in this period will remain near climatological normals. Near-normal temperatures are anticipated. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... VFR conditions will likely prevail at both CHS and SAV terminals through 18z Sunday. However, there is a fair chance of showers and/or thunderstorms impacting either terminal this evening into early tonight. Confidence in timing remains quite low, but have included VCSH between 22z-02z at the CHS terminal when chances of precip appear slightly higher. Otherwise, gusts as high as 15-20 kt will be possible for the next couple hours at the CHS terminal. Extended Aviation Outlook: Potential for brief restrictions will exist at KCHS and KSAV each day if terminals are directly impacted by showers/thunderstorms, primarily during afternoon and early evening hours. && .MARINE... This Evening and Tonight: The pressure gradient will remain somewhat enhanced across the marine zones between Atlantic high pressure and a trough of low pressure that reaches the Coastal Plain this evening. The setup favors a 15-20 kt southwest wind over much of the coastal waters to start off the night. Gusts of 25 kt should also be common over northern South Carolina waters until around midnight tonight when the pressure gradient begins to relax. As a result, A Small Craft Advisory will now be in effect until 2 AM tonight. Otherwise, winds will continue to decrease over all waters later tonight. Seas will range between 2-4 ft over most waters while peaking briefly to 5 ft over portions of northern South Carolina waters beyond 15 nm from the coast. Sunday through Thursday: The coastal waters will remain situated between Bermuda high pressure to the east and a lee trough to the west. This will maintain S to SW flow with the typical enhancements along the coast with the afternoon sea breeze and over the nearshore waters during evening nocturnal jetting. Rip currents: Gusty south/southwest winds are likely along the beaches into early evening. These winds in combination with the upcoming full moon this weekend support a moderate risk of rip currents for Charleston County into evening hours. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None.
