25What forecasters said that day
The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Aug 11, 2:36 PM EDT, 1 hour 4 minutes earlier.
Area forecast discussion, Aug 11, 2:36 PM EDT, 1 hour 4 minutes before
Area Forecast Discussion National Weather Service Charleston WV 236 PM EDT Sat Aug 11 2018 .SYNOPSIS... A deep closed low pressure system approaches from the north tonight and lingers overhead through early next week. && .NEAR TERM /THROUGH SUNDAY/... As of 200 PM Saturday... Wx charts show a weak frontal boundary across southeast OH at 18Z. Diurnal heating and abundant moisture will keep this storm activity through sunset. Expect convection to gradually diminish after sunset. This reasoning comes from high bouyancy, low deep layered shear, and PWATs reaching 1.8 inches. Very heavy downpours can be expected per slow storm motion and repetitive showers. The most likely area that could experience water issues will be southern portions of southeast OH, the tri-state area, and portions of southern WV. Convection will tapper off later tonight with areas of dense fog developing over areas that clear overnight. Any fog will dissipate by 13Z Sunday. The diffused frontal boundary will linger overhead Sunday, and will serve as the focus mechanism for the development of showers and thunderstorms mainly during the afternoon and evening hours. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... As of 230 PM Saturday... Upper low continues to linger across the area Sunday night into Monday, with continued showers and thunderstorms, particularly during afternoon hours. The low will slide off to the east on Tuesday, with a gradual drying trend taking hold Tuesday night. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 235 PM Saturday... Upper low moves off to the east Tuesday night, with upper ridging taking hold for Wednesday, providing dry and warmer conditions. The dry spell is short lived however, as another upper shortwave trough approaches for the end of the week. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... As of 145 PM Saturday... Pockets of clearing and low level available moisture contributed to scattered showers and storms mainly across southeast OH and along the northeast mountains. Brief periods of IFR/LIFR conditions possible along the heaviest storms. Otherwise, VFR conditions will prevail at least through 06Z. There is a chance that areas that receive rainfall this afternoon and evening to fog before 06Z tonight. After 06Z, dense fog is expected to develop along river valleys as BL winds still weak, and clearing should spread from west to east overnight. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SUNDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: After rainfall, an IFR low stratus deck could develop overnight and prevent fog formation.
