The episode as NWS RLX wrote it up.
On the northern periphery of an upper level ridge, a subtle short wave kicked off showers and thunderstorms on the 25th. Heavy rainfall led to minor flash flooding in Washington County.
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 May 25, 10:52 AM EST, 2 hours 38 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Charleston WV 1152 AM EDT Sat May 25 2019 .SYNOPSIS... Convective activity on the northern side of the ridge tonight. A weak cold front approaches the area Sunday into Monday, before returning north as a warm front early next week. && .NEAR TERM /THROUGH TONIGHT/... As of 1150 AM Saturday... Mid to upper ;level short wave trough crossing the area has not amounted to much, its comma head pattern visible in GOES-R imagery, coincident with associated scattered showers. Scattered convection may persist in its tail in and near the mountains through mid afternoon. As of 635 AM Saturday... Bumped up temperatures slightly area wide this afternoon. Also timed the showers in central KY for arrival in our western CWA using the WRF and RAP. As of 240 AM Saturday... Life on the northern side of the upper level closed high/ridge will continue to be on the active side through today. First off, will be tracking a subtle mid level wave currently producing showers over central KY this morning, and expect this to ride the upper level flow into the CWA in the late morning hours. NAM and rapid update models have been keying on this feature for several hours. Early arrival should not have an affect on inhibiting later convection during the afternoon/evening as the atmosphere should have plenty of time to recover once it moves through and out of the CWA, not to mention the surface based instability could increase from it. Expect some blossoming of storms later today, and along with the thinking from SPC, stronger storms should reside over the northern CWA. Any storms advecting into the CWA, especially north, will be moving into an overall favorable environment for sustainability despite weaker mid level lapse rates and a profound lack of moisture above 650mb or so. Activity should wave significantly with sunset. An overnight MCS tracking nearly west to east from the mid Mississippi Valley warrants POPs across the west for later into the overnight. Temperatures/dewpoints continue the warm and muggy trend. 70F dewpoints likely again today. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... As of 200 AM Saturday... A frontal boundary will remain near the area for Sunday into Monday, before returning northward as a warm front. This will provide periods of showers and thunderstorms. With the front providing a focusing mechanism, there is some concern that flash flooding could become an issue. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 200 AM Saturday... An upper level ridge will build over the region for Tuesday and Wednesday, allowing for 20 C temperatures at 850 mb. This could allow temperatures to reach into the lower 90s for much of the lowlands. A cold front or series of cold fronts will then effect the area for late in the work week. Still considerable differences between the models in the timing of these fronts and the intensity of the cooler air behind them. This leads to a lower confidence forecast for late in the week. && .AVIATION /16Z SATURDAY THROUGH WEDNESDAY/... As of 635 AM Saturday... Expecting more rounds of scattered showers and thunderstorms for the region later this morning through the early evening. Tailored the timing of the convection at each terminal with the highest POPs in the forecast, but this could change going forward. AMDs likely today as IFR and prevailing TSRA are not in the 12Z forecast. For the terminals that receive rain, and expect this to be all of them at some point through the day, this will pave the way for fog tonight. Trended this to IFR visibilities for after 06Z Sunday, which will likely need to be lower in some cases, but wanted to convey the degrading conditions expected in valley fog. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SUNDAY... FORECAST CONFIDENCE: Low. ALTERNATE SCENARIOS: Shower and thunderstorm timing could vary from forecast. Fog development tonight could vary from forecast timing.
