The episode as NWS RLX wrote it up.
On the morning of August 14th, an advancing cold front, coupled with a strong upper level system, produced showers and thunderstorms. Heavier bursts of rain in southeast Ohio led to one instance of flash flooding in Gallia County. A section of State Route 850 was closed for a brief period of time due to a local creek spilling out of its banks and onto the roadway. Precipitation coverage quickly shifted eastward by the early afternoon.
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 Charleston, WV wrote its last area forecast discussion before the first event at Aug 14, 4:44 AM EST, 2 hours 46 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTED National Weather Service Charleston WV 544 AM EDT Mon Aug 14 2023 .SYNOPSIS... Warm front today. Severe storms are possible this afternoon and evening. A cold front pushes through Monday night. A quieter pattern ensues the rest of the week. && .NEAR TERM /THROUGH TONIGHT/... As of 210 AM Monday... An approaching cold front will combine with a strong upper level system to produce impressive dynamics across the region today and tonight. Timing of an early line of precipitation however, could hamper surface heating today, thus possibly serving as a disrupter for severe weather potential. The meso NAM is showing that northern West Virginia and east central Ohio never realize CAPE values over 1000 due to this line. Northeast Kentucky, southwest West Virginia and southwest Virginia would have the most time to recover with the Meso Nam showing effective layer CAPE now only recovering to 1200 to 1700 (yesterday it was showing 2000 to 2500). Models also not showing a cap on the sounding between the first line and maximum CAPE, meaning that other thunderstorms could form and kill the energy before the CAPE fully rebuilds. Therefore, this is not a perfect setup for severe weather, but due to the impressive dynamics, it remains a possibility. Due to some areas of northern West Virginia getting 1.5 to 2 inches of rain Saturday night, and models showing precipitable water of 1.75 to 2.25 inches today and tonight, there is a concern for flash flooding. Working against this however is that the storms should be moving rather fast and in northern West Virginia where the flash flood guidance is the lowest, the meso NAM is not showing over 1000 CAPE. Will hold off on a Flash Flood Watch for now, but will need to keep a close eye on the potential for any training storms that could produce flash flooding. && .SHORT TERM /TUESDAY THROUGH THURSDAY/... As of 245 AM Monday... Key Points: * Chances for scattered showers and storms persist until the axis of a trough crosses Tuesday night into early Wednesday. * Cooler through mid week, temperatures warm again Thursday. A 500mb trough shifts eastward overhead, maintaining chances for scattered showers and storms until the axis of the trough crosses Tuesday night into early Wednesday. High pressure building in behind this trough brings drier air into the area during the day Wednesday. Quieter weather then persists as high pressure remains in control through Thursday. A cooler air mass - arriving behind today's cold front - will keep temperatures below normal into mid week, with high temperatures likely remaining in the 70 to 80 degree range in the lowlands and mid 60s to 70s along the mountains. Temperatures moderate back to normal for Thursday. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... As of 245 AM Monday... Key Points: * Little to no precipitation expected with a late week front. * Dry, with high pressure building this weekend. A shortwave trough crossing to the north is projected to bring a front through the CWA Thursday night into Friday. While models generally agree on the timing of the front, there is some question as to how much - if any - precipitation will accompany its passage. At this point, model ensembles generally favor drier conditions. Surface high pressure and an upper ridge build in behind the front, resulting in a dry and quiet weekend. Temperatures are expected to be near normal at the start of the long term period, then rise above normal this weekend. && .AVIATION /12Z MONDAY THROUGH FRIDAY/... As of 540 AM Monday... Showers and thunderstorms will move into the area this morning and cause restrictions as a warm front pushes northward across the area. Showers and thunderstorms will continue to be a possibility today, with some this afternoon possibly producing damaging winds and large hail. A cold front will then push through tonight. Showers and thunderstorms remain a possibility along and in advance of the front. Behind the front, some MVFR stratus and lighter rain showers remain a possibility.
