The episode as NWS GSP wrote it up.
Isolated to widely scattered thunderstorms developed ahead of a cold front during the afternoon across upstate South Carolina. A few of the storms produced large hail and brief damaging wind gusts.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at May 16, 1:29 PM EST, 52 minutes earlier.
Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 229 PM EDT Mon May 16 2022 .SYNOPSIS... Relatively dry high pressure returns Tuesday into Wednesday. A subtropical airmass will spread over the area Thursday, bringing hot weather to the area which will last into the weekend, along with seasonable chances for showers and storms. Scattered to perhaps numerous showers and thunderstorms are expected this weekend ahead of a cold front. && .NEAR TERM /THROUGH TUESDAY/... As of 150 PM EDT Monday: Isolated to scattered convection has developed ahead of the cold front crossing the area. Best coverage still expected over NC and the eastern Upstate. Can't rule out a strong to possibly even severe storm, mainly over and east of the I- 77 corridor, but chances are better to our east. Convection moves out of the area by early evening. Gusty west to NW winds expected until early evening when speeds drop off and direction turns more northerly. Skies clear through the evening as well. Can't rule out some mountain valley fog, especially in the Little TN Valley. However, chances very low elsewhere. Lows will be slightly below normal. N to NW winds and drier dew points expected Tuesday as high pressure builds in from the west. No convection expected either. Highs will be up to 5 degrees above normal. && .SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 221 PM Monday: The middle part of the week still looks relatively quiet across the area as we should be underneath a quasi-zonal flow through Wednesday. Sfc high pressure should move off the Mid-Atlantic coast Tuesday night, beginning the warming trend. Thus, our near normal low temps Wednesday morning will be the last we will see for a few days. Highs Wednesday will be on the order of ten degrees above normal, and Wednesday night will remain warm. The wildcard in the fcst will be the possibility of MCS remnants that could track eastward and reach the fcst area before dissipating late Wednesday or early Thursday. This will mainly be a concern over the mountains, but not a very great one at this stage. && .LONG TERM /THURSDAY THROUGH MONDAY/... As of 203 PM Monday: Still looking like July for the end of the week as the upper pattern amplifies with a ridge on the East Coast supporting a Bermuda High beginning on Thursday. A sfc boundary strung out west-to-east across the central Appalachians might just be close enough to help trigger/organize a few storms across the nrn part of the fcst area during the afternoon/evening on Thursday, but don't bet on it right now. Instead, this day should be our first of the year with many temps reaching the lower 90s outside of the mtns. The upper ridge amplifies quickly Thursday night into Friday. The ensuing deep warm layer aloft will not be conducive to any deeper convection on Friday because the moisture will not have come up from the Gulf yet, so expect Friday to be rain-free. Some locations might make it to the middle 90s. The weekend looks much more unsettled, but confidence on which day might be the more active of the two is sketchy, and it will depend on the timing of a front being driven eastward by a short wave moving through the trof to our west. The ECMWF is more suggestive of Saturday, while the GFS is more Sunday. Either way, we may find ourselves at the southern end of a severe thunderstorm risk one or both days with modest buoyancy and shear, but a cold front to trigger/organize the storms. Temps will be mid-summer-like over the weekend, but the passage of the cold front, probably Sunday, will knock them back down to around normal for Monday. Assuming the pattern stays progressive, that would mean Monday would be quiet with high pressure moving past to our north. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... At KCLT and elsewhere: Isolated to sct convection has formed ahead of a cold front crossing the area. Have TEMPOs in place for TSRA and vrb gusty winds based on radar and latest guidance trends. Winds turn NW behind FROPA with maybe some lingering gusts which end by early evening as winds turn more northerly. SCT Cu and BKN Ci diminish this evening with clear skies expected overnight. Can't rule out some mountain fog in the Little TN valley again, but don't expect any at KAVL. Clear skies with N to NW wind expected Tuesday. Outlook: Dry conditions continue into Wednesday. Summerlike conditions expected through Friday, with slowly increasing chances of afternoon convection and nocturnal fog/stratus occurring wherever rain has fallen the previous afternoon. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...None. NC...None. SC...None. && SYNOPSIS...DEO NEAR TERM...RWH SHORT TERM...PM LONG TERM...PM AVIATION...RWH
