An isolated severe thunderstorm produced wind damage in Newberry Co SC.
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 Columbia, SC wrote its last area forecast discussion before the first event at Jun 29, 6:57 PM EST, 53 minutes earlier.
Area Forecast Discussion National Weather Service Columbia SC 757 PM EDT Mon Jun 29 2020 .SYNOPSIS... An upper level trough will be over the eastern US through much of week. At the surface a weak boundary will be stalled over the area and combine with abundant low level moisture to produce diurnally driven convection. Although, several upper level shortwaves may enhance convective activity outside of peak heating hours as well. Late in the week, the closed upper low will move east and should be replaced by a weak upper trough. This will continue shower and thunderstorm chances into the weekend. Temperatures will be near normal for much of the period. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... Regional radar showing convection in the Upstate early this evening. Weak to moderate instability across the Midlands and CSRA, so could see storms move into the Midlands and CSRA this evening as shortwave energy moves through. Ample moisture is in place with pwat values around 1.6 to 1.9 inches. MLCAPE around 1000 to 2000 J/kg. Some of the storms could contain strong to damaging winds with DCAPE values 800 to 1200 J/kg. The overall severe threat is low given weak shear and disorganized nature of expected convection. Overnight lows will be in the low to mid 70s with some cloud cover and mixing expected. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY NIGHT/... The upper level low will linger over the Northeast through mid week. During the short term, a series of upper level disturbances will round the base of the trough and move over the Mid Atlantic and Carolinas. At the surface a weak surface boundary will also sag into the region. This will provide an area of convergence as well as a focus for increasing low level moisture. PW values increase to around 2.0 inches across the Midlands and CSRA. This will be a focus for afternoon/evening showers and thunderstorms. SPC has the area outlooked for a marginal risk of severe thunderstorms for Tuesday. Model soundings indicate a bit of a inverted v sounding and main threat will be potential for strong damaging wind gusts. There will be a very similar setup across the area for Wednesday. SPC day 3, also has a marginal risk of severe thunderstorms across the area. Once again wind will be the main issue with strong/severe thunderstorms. Both days, storm motion should be from NW to SE at around 20 kts, which should help with potential for any flash flooding. However, with PW values around 2.0 inches storms will have the ability to produce locally heavy rainfall. With the convergence boundary in the area any training of storms could produce locally high rainfall amounts. Highs each day will be seasonable with highs in the low/mid 90s and overnight lows in the lower 70s. && .LONG TERM /FRIDAY THROUGH MONDAY/... The blocking pattern may give way late this week allowing the closed upper low to shift out of the CONUS. During the remainder of the long term period, models favor weak troughing over the eastern US, with the trough axis west of the FA. An associated surface low may develop over the weekend into early next week and keep the region in a wet pattern/slightly cooler temperatures along with diurnal showers and thunderstorms for the holiday weekend. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/... VFR Conditions expected to persist through the forecast period. Only chance at restrictions will exist in convection at the beginning of the time frame and towards the end. As of 29/2345z, a cluster of strong to severe thunderstorms has developed to the NW of CAE/CUB. This is marching SE, and looks like it should persist into the region and impact CAE/CUB in the 01-02z timeframe; have included a tempo group to account for this. Wind could be gusty with these storms, and they could reduce visibilities at both airports with heavy rainfall. There is a chance that this holds together and moves into the OGB area, but holding off on a tempo group for now. Isolated showers are popping up around the AGS/DNL region, but are more hit and miss. All showers/storms should weaken with the loss of daytime heating. Overnight, winds will really die down at all TAF sites, with some falling to 0 or 1 kt overnight. Guidance is suggesting that mid/high level clouds will remain, precluding a risk of fog across the region. Winds will pick back up as we warm up after sunrise tomorrow before our next expected weather impacts. Showers and thunderstorms should be numerous across the entire forecast area tomorrow afternoon, but specific timing of when these will impact TAF sites is unknown at this time. Have included VCTS at all TAF sites to account for this until more specific timing can be nailed down. .EXTENDED AVIATION OUTLOOK...The chance for restrictions from diurnal convection will persist through Friday. && .CAE WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None. && SYNOPSIS...99 NEAR TERM...99 SHORT TERM...99 LONG TERM...99 AVIATION...99
