The National Weather Service in Charleston has issued a * Flash Flood Watch for a portion of southeast South Carolina, including the following areas, Charleston, Dorchester, Inland Berkeley, and Tidal Berkeley. * from 4 AM EDT Friday through Friday morning * A cluster of thunderstorms are forecast to develop along the South Carolina coast during the pre-dawn hours Friday. These thunderstorms are expected to expand across Charleston, Dorchester, and Berkeley Counties through the early daylight hours on Friday. By late morning, the storms should push inland of the region. These slow moving storms will develop in a very moist environment and will be capable of torrential downpours. Average rainfall may range between 1.5 to 2.5 inches, isolated amounts as high as 5 inches are possible. * Heavy rainfall was observed across portions of the Charleston Tri-County area on Thursday. The heavy rainfall produced multiple flooded roads, especially around the Summerville area. In addition, the heavy rainfall over recent days has resulted in elevated water levels on small creeks and streams. The heavy rainfall expected Friday morning could result in flash flooding along streams and creeks and within urban areas. PRECAUTIONARY/PREPAREDNESS ACTIONS... Be prepared to protect life and property, especially in areas prone to flooding. If flooding develops, move to higher ground immediately. If driving, be prepared for flooded roadways and possible road closures. && $$ NED

What forecasters said that day
The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, SC wrote its last area forecast discussion before this flash flood watch went out at Aug 2, 7:58 PM EDT, 2 hours 15 minutes earlier.
Area forecast discussion, Aug 2, 7:58 PM EDT, 2 hours 15 minutes before
Area Forecast Discussion National Weather Service Charleston SC 758 PM EDT Thu Aug 2 2018 .SYNOPSIS... Unsettled conditions will persist through Friday as the region remains situated between high pressure offshore and an inland trough of low pressure. Atlantic high pressure will build in for the weekend, before another inland trough develops during the early and middle parts of next week. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... Tonight: Aloft, the area will remain positioned between a ridge of high pressure over the western Atlantic and a trough of low pressure inland. At the sfc, a light onshore will continue to pull moist air off the Atlantic ahead of a large line/cluster of weakening showers and thunderstorms currently shifting north through parts of Southeast Georgia and Southeast South Carolina late this evening. Expect the bulk of this activity to drift north over the next couple hours, producing episodes of locally heavy rainfall and gusty winds. The risk of severe weather remains fairly low, especially with the loss of diurnal heating heading into early tonight. Given the latest trends, numerous to widespread showers and thunderstorms are included in the forecast late this evening with a south to north ending trend as we approach midnight. Given PWATs remain around 2.0 inches overnight, there remains a chance of precip through the morning. Much like previous nights, CAMs suggest showers and thunderstorms redeveloping over coastal waters late and eventually shifting onshore around daybreak, especially along the Southeast South Carolina coast. Heavy rainfall will once again be a concern around daybreak near the coast. Overnight lows remain on track despite recent cooling from convection. In general, lows should range in the low/mid 70s inland to upper 70s along the coast. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/... Friday: An unsettled weather pattern will persist over the Southeast United States as the area remains positioned between high pressure over the western Atlantic and a trough of low pressure inland. A southwest flow between these two features will continue to advect deep moisture to the area while an onshore sfc wind also draws moisture from the Atlantic. Much like the past several days, the morning should start off with coastal showers/thunderstorms that shift onshore, especially along much of the Southeast South Carolina coast. PWATs around 2.0 inches along with SBCAPE around 1250 J/kg suggest a localized heavy rainfall threat with the potential for minor flooding, starting off in the Quad County area early before shifting inland. Precip activity should trend westward through the afternoon as a seabreeze circulation develops and shifts inland with most areas experiencing scattered to numerous showers/thunderstorms by late afternoon. A stronger and/or briefly severe thunderstorm can not be ruled out during peak heating, but the overall threat will remain low. In general, high temps should reach the upper 80s for most areas. Models indicate a Tutt Low shifting north off the Mid-Atlantic coast late in the day, which should allow the Atlantic ridge to begin building over the Southeast by early night. Given the expected trend, a slightly quicker end to shower/thunderstorm activity should occur during the evening and/or early night hours. Low temps should range in the mid/upper 70s, coolest inland. Saturday and Sunday: High pressure will strengthen over the western Atlantic this weekend, building across the Southeast United States and presenting a much more typical summertime environment than experienced over the past several days. The bulk of deeper moisture will shift inland and perhaps just north of the region, leading to noticeably less shower and thunderstorm coverage through late weekend into early next week. However, a slight chance to chance of showers/thunderstorms will remain possible, mainly along an inland moving seabreeze each afternoon. Given the building ridge aloft, 1000-850mb thicknesses will be marginally greater and suggest overall high temps peaking in the lower 90s away from the immediate coast. Overnight periods should be rain free for most locations with lows temps ranging in the low/mid 70s inland to upper 70s near the coast. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... Mid and upper ridging overhead early next week will drop S into the middle of next week, as various short waves help to establish a broad trough over much of the eastern half of the country. Similarly at the surface the Atlantic ridge is bumped S-SE as a lee-side trough develops. Moisture is limited by a deep offshore flow, but should be sufficient enough to combine with lift from the sea breeze and nearby trough, and typical summer instability to produce at least a chance of showers and t-storms through the period. A slight downslope component of winds and H8 temps as high as 19-20C will support max temps at least in the lower 90s each day. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/... Showers and thunderstorms could impact both terminals over the next hour to two when tempo MVFR conditions have been included between 01-03Z Friday at CHS and 00Z-01Z at SAV. A period of VFR conditions are then expected until late tonight and/or around daybreak before another round of showers and/or thunderstorms shift onshore and mainly impact the CHS terminal. Tempo MVFR conditions have been included between 12-16Z Friday to account for morning precip at CHS. Confidence is too low to include flight restrictions at the SAV terminal late Friday morning. Extended Aviation Outlook: Flight restrictions are possible at both CHS and SAV terminals Friday for occasional heavy rains and gusty winds within scattered showers/thunderstorms. VFR conditions should then prevail Saturday through Monday as high pressure builds over the area, but an afternoon shower and/or thunderstorm will remain possible each day and could produce brief flight restrictions. && .MARINE... Tonight: The coastal waters will remain sandwiched between high pressure offshore and an inland trough. Expect southerly winds peaking around 15 kt. Seas will average 2-4 ft. Friday through Tuesday: The area will remain along the western edge of high pressure to start off the weekend with south/southeast winds generally remaining at or below 10-15 kt outside shower/thunderstorm activity. Southerly winds should gradually decrease and remain around 10 kt or less late this weekend and early next week as the Atlantic high builds over the coastal waters and dominates the weather pattern. Shower and thunderstorm coverage should also become noticeably less as well late this weekend into early next week. Waterspouts: Given lighter wind fields there appears to be some potential for isolated waterspouts each morning from Saturday through Monday. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None.
