What forecasters said that day
The local office's own words before this flash flood warning went out, 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 this flash flood warning went out at Sep 1, 2:12 PM EDT, 15 minutes earlier.
Area forecast discussion, Sep 1, 2:12 PM EDT, 15 minutes before
Area Forecast Discussion National Weather Service Charleston WV Issued by National Weather Service Pittsburgh PA 212 PM EDT Sat Sep 1 2018 .SYNOPSIS... Showers/thunderstorms will be possible across the region on Labor Day Weekend with the higher elevations having the greatest chance of receiving storms each day. Temperatures will be well above normal for September and heat index values may reach near 100 by next week. && .NEAR TERM /THROUGH TONIGHT/... As of 940 AM Saturday... Fog that developed overnight has dissipated leaving the region with mostly sunny skies. However, satellite imagery shows a large area of clouds was pushing east into the area. Radar mosaic continues to show showers and thunderstorms were moving east across portions of Ohio and Kentucky. Have made tweaks to sky, temps and POPS to reflect the latest trends and guidance. Previous Discussion... The previous forecast remains on track. Fog has been limited to the far northern and eastern portions of West Virginia as cloud cover elsewhere has inhibited widespread development. Any fog will quickly mix out after sunrise. Warm, humid conditions are expected over labor day weekend. Showers/Tstorms will develop in the afternoon hours as diurnal heating destabilizes the atmosphere. A weak shortwave rotating around the NW periphery of the Atlantic High may help initiate some convection today. Otherwise, most activity will be confined to the higher elevations where insolation combined with this warm, moist boundary layer will more than suffice for tstorm development. Forecast soundings are rather unimpressive for organized or severe convection. Winds will be mostly light and uniform through the profile. Lapse rates are modest at best. Still, lapse rates will climb to near or in excess of 1500 J/kg during peak heating. Not much in terms of capping... so will likely see a decent CU field with some showers or weak thunderstorms. && .SHORT TERM /SUNDAY/... Convection will diminish after sunset Saturday with the loss of heating. Broken or perhaps overcast skies will likely prevent widespread fog formation... but like this morning, valley fog will still be possible in the most susceptible areas. Sunday will be similar but with a few less storms as high pressure builds into the region. Temperatures will remain well above seasonal both days. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... The hot, humid conditions will continue through the long term period. Models are in good agreement that a H5 595+ dm high pressure becomes nearly centered over the region through late next week or just east, allowing for persistent southerly flow in the low levels. This will keep the stream of very warm, moist air in place. Without much in the way of upper level forcing, convection will be mostly confined to the Allegheny Front / other high elevations during peak heating. Temperatures will be much above normal over the next 7 days. Heat index values may very well reach near or above 100 outside of the high elevations. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... Scattered showers and thunderstorms with IFR conditions have developed across the region. Outside of the precipitation, VFR conditions prevailed. Expect the storms will continue into the evening hours with storms dissipating after sunset. With light winds and few clouds, dense fog will likely develop after midnight in the favored valley locations as well as locations that receive rainfall today. Any dense fog that develops overnight should dissipate after sunrise on Sunday with VFR conditions expected region-wide. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SUNDAY... FORECAST CONFIDENCE: MODERATE ALTERNATE SCENARIOS: The coverage and intensity of the fog may vary. EXPERIMENTAL TABLE OF FLIGHT CATEGORY OBJECTIVELY SHOWS CONSISTENCY OF WFO FORECAST TO AVAILABLE MODEL INFORMATION: H = HIGH: TAF CONSISTENT WITH ALL MODELS OR ALL BUT ONE MODEL. M = MEDIUM: TAF HAS VARYING LEVEL OF CONSISTENCY WITH MODELS. L = LOW: TAF INCONSISTENT WITH ALL MODELS OR ALL BUT ONE MODEL. AFTER 18Z SUNDAY... May have brief IFR in thunderstorms Sunday. && .RLX WATCHES/WARNINGS/ADVISORIES... WV...Flash Flood Watch until midnight EDT tonight for WVZ522>526. OH...None. KY...None.
