NWS Charleston, WV wrote its last area forecast discussion before the first event at Aug 9, 1:43 PM EST, 2 hours 17 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Charleston WV 243 PM EDT Mon Aug 9 2021 .SYNOPSIS... Upper level disturbances bring isolated/scattered afternoon showers and storms through the work week, with the heat and humidity continuing. A cold front approaches the area late Friday. && .NEAR TERM /THROUGH TUESDAY/... As of 230 PM Monday... Showers and storms are moving into the area this afternoon as a system pushes in from the east. Greatest instability remains west of the area today, though some moderate instability and higher moisture to the west and southwest could allow for a few stronger, possibly severe storms to develop. SPC has included our northeast KY counties and portions of southeast Ohio, southwest WV, and southwest VA in a marginal risk for severe weather with wind as the main threat. Heavy rain may also accompany stronger storms today. Showers and storms are expected to diminish in coverage tonight, then increase again early on Tuesday as a shortwave trough slides by to the north. High moisture and daytime heating will then keep chances for showers and storms present into the evening. With moderate instability and steepening lapse rates in the afternoon, it is possible for isolated storms to become strong to severe. A marginal risk of severe weather is present for the entire CWA with wind as the main threat. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... As of 240 PM Monday... The warm spell featuring abnormally high temperatures and heat indices stretching into the upper 90s/low 100s continues through the period amid stagnant upper level flow. With no reprieve from this current pattern we find ourselves in, the opportunity for diurnally driven showers and thunderstorms will remain present each day through the work week. With a plethora of instability hanging overhead, strong to potentially severe thunderstorms will be advertised each day. A cold front will begin dropping down from the northern Plains after midweek and aim for the Central Appalachians closer to the weekend. Until then, expect very warm afternoons and the potential for thunderstorms during prime heating hours. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... As of 240 PM Monday... A change in the weather pattern arrives in the form of a cold front late in the work week. Widespread showers and thunderstorms will accompany the boundary, followed by a burst of cooler air in the wake of its passage, cooling us back down closer to our climatological norm. Upper level high pressure banked up along the eastern seaboard will begin to break down over the weekend as the surface cold front gets hung up along our southern borders. The boundary is progged to become stationary through the conclusion of the forecast period and promote a chance for precipitation as far north as the Ohio River Valley into the start of next week. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... As of 155 PM Monday... Isolated showers have developed this afternoon, so have coded VCSH at most sites to account for them. Widespread showers and storms are also moving into the area from the east as a system approaches. These showers/storms are expected to continue through the evening. Activity should diminish for the first part of the night, then increase again late tonight into Tuesday. VFR conditions should persist for much of the area through the valid TAF period; however, MVFR/IFR is possible within showers or storms this afternoon and evening. Also, if enough clearing occurs overnight some fog could develop in the mountains, but confidence remains low. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing of showers and thunderstorms could vary. If fog develops, IFR/LIFR conditions may be possible in the mountains.
