What forecasters said that day
The local office's own words before this small craft advisory 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 small craft advisory went out at Aug 31, 2:00 PM EDT, 1 hour 22 minutes earlier.
Area forecast discussion, Aug 31, 2:00 PM EDT, 1 hour 22 minutes before
Area Forecast Discussion National Weather Service Charleston SC 200 PM EDT Tue Aug 31 2021 .SYNOPSIS... High pressure will shift off the Southeast coast today as the remnants of Ida lift into the Tennessee Valley. A cold front will pass through the region Wednesday night into Thursday, followed by high pressure through the weekend. && .NEAR TERM /THROUGH TONIGHT/... Early this afternoon: Radar imagery shows that the anticipated line of thunderstorms is approaching from the southwest with isolated convection developing out ahead of it. The near storm environment is somewhat conducive to severe weather potential, mainly in the form of damaging wind gusts. Ahead of the line, DCAPE values increase into the 800-1,000 J/kg range with MLCAPE on the order of 1,500-2,500 J/kg. Most of the shear is displaced to the west, but the upstream storms are displaying decent momentum with storm motion approaching 30 knots. Storms should reach the Altamaha River counties by around 245 pm or so. Late this morning: Visible satellite imagery shows that much of the forecast area is under full sun, with the beginnings of scattered diurnal cumulus across the Tri-County and increasing high clouds approaching interior southeast Georgia. The main forecast issue today will be determining if a broken band of scattered showers and thunderstorms can develop west of the area and make it in late in the day. The airmass across the forecast area will undergo some changes today and we can see this coming in 12z RAOB data from surrounding sites. For example, precipitable water values across the region vary from 2.04" at KFFC, 1.76" at KJAX, and 1.13" at KCHS. Furthermore, the difference in the near storm environment from central Georgia to southeast South Carolina is pretty stark. KFFC shows a 0-3 km SRH of nearly 400 m2/s2 and shear of 40 kt, meanwhile KCHS has virtually no SRH and only a meager 15 kt of 0-3 km shear. All that to say, it is obvious why there is a Slight Risk to the west across much of southern and central Georgia near the remnants of Ida. The the afternoon, over the last several days model solutions have tended to only show isolated at best coverage. This appears to be mainly because as the bands associated with the remnants of Ida progress eastward they run into drier air and an environment less conducive to maintenance or development. The HREF and the HRRR continue to support rain chances in the 20-30 percent chance range for the western half of the forecast area late in the afternoon. The HRRR is showing considerable run to run differences though, with some solutions even being completely dry. Given the amount of heating and expected destabilization, it is hard to argue that we won't at least see isolated coverage. With that in mind, we have maintained the PoP scheme we had in place. It isn't out of the question that if a few storms can make it in that they could become strong to possibly marginally severe as the better storm environment start to make eastward progress. No changes to highs today with low 90s just about everywhere. Winds will be a little breezy along the coast today, with frequent gusts into the 20-25 mph range especially along the Charleston County coast. Tonight: What's left of Ida will approach the southern Appalachians as the trough to our west-northwest draws closer to the local vicinity. There is some QG-forcing that occurs in advance of the trough, and higher PWat spreading eastward with time. However, the CAPE and instability is rather insignificant, with the exception of coastal Charleston, where there is also some low level convergence within a south-southwest synoptic flow. Due to this scenario we look for mainly 20/30 PoPs. Winds never fully decouple and actually remain a little breezy at times near the coast. This will keep min temps about 2-4F above climo. && .SHORT TERM /WEDNESDAY THROUGH FRIDAY/... Aloft, high pressure will prevail over the adjacent coastal waters while the remnants of Ida and the associated upper level low pressure maneuvers from the Tennessee River Valley into the Mid- Atlantic states. Moisture will increase across the forecast area Wednesday as a cold front approaches the region associated with the remnant low. There continues to be some model discrepancy, leading to uncertainty in the coverage of precipitation. However, with PWATs greater than 2 inches and the synoptic forcing from the cold front, showers and thunderstorms will likely occur, with highest chances across the northern zones. After the cold front passes through the region Wednesday night into Thursday, drier air will replace the previously moist atmosphere, decreasing precipitation chances. High pressure will build into the region Friday, both aloft and at the surface. Temperatures Wednesday will top out in the upper 80s due to ample cloud cover over the region. Low temperatures Wednesday night will range from the low to mid 70s. Thursday and Friday both feature high temperatures in the upper 80s. Lows Thursday could dip into the upper 60s inland, with mid 70s closer to the coast. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... High pressure will continue to build into the region through the weekend, bringing drier air and cooler temperatures. High temperatures should be a degree or two below normal, with low temperatures dropping into the upper 60s inland. Monday a weak front looks to approach the region, bringing the possibility of showers and thunderstorms back. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... VFR conditions should mostly prevail with the best chance for MVFR or lower conditions coming with direct impacts from showers and thunderstorms. This afternoon, the best chance for showers and thunderstorms will be at KSAV where a few have already developed upstream of the terminal. These are moving quickly so any impacts should be short-lived. Have initialized KSAV with VCTS and a TEMPO group for TSRA conditions. Overnight, while there could be an isolated shower or thunderstorm just about anywhere at anytime, direct impacts at the TAF sites are unlikely. Additional showers and thunderstorms are expected to start developing by mid morning Wednesday and the best coverage should be near KCHS and KJZI. Confidence in direct impacts is too low to include anything more than VCSH at this point. Gusty southwesterly winds outside of any thunderstorms are expected to begin developing by mid to late morning Wednesday. Extended Aviation Outlook: Flight restrictions are possible with showers and thunderstorms Wednesday. Otherwise prevailing VFR. && .MARINE... Today and tonight: High pressure pulls further offshore as TD Ida moves through parts of the Southeast. The gradient steadily becomes tighter, and eventually transitions from anticyclonic today to cyclonic by late today and tonight. Under these circumstances, S and SW winds will climb as high as 15 or 20 kt throughout the entire marine area, with even some higher gusts at times. Seas will respond to the higher winds to build from 2-3 feet today to 3-4 feet tonight. Wednesday through Sunday: The pressure gradient will tighten Wednesday as the remnants of Ida move from the Tennessee Valley into the Mid-Atlantic states. This tightened pressure gradient will support sustained southwesterly winds of around 20 knots across all of the waters, with frequent gusts to 25 knots. In addition, seas are expected to be 4 to 6 feet, especially in the Charleston County waters and the 20 to 60 nm GA waters, with 3 to 4 feet elsewhere. Small Craft Advisories will likely be needed for most waters, including Charleston Harbor Wednesday afternoon into Thursday morning. A cold front is expected to cross the waters Wednesday night into Thursday, shifting winds to west northwesterly by Thursday afternoon generally 10 to 15 knots. Seas will also reduce to 2 to 3 feet by Friday morning. High pressure will prevail through the weekend, no additional marine concerns are expected. Rip Currents: Building seas and gusty winds will create conditions conducive for the formation of rip currents, therefore a moderate risk has been raised for all beaches Wednesday. && .CHS WATCHES/WARNINGS/ADVISORIES...
