The local office's own words before this special weather statement 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 special weather statement went out at May 24, 1:42 PM EDT, 33 minutes earlier.
Area forecast discussion, May 24, 1:42 PM EDT, 33 minutes before
Area Forecast Discussion National Weather Service Charleston WV 142 PM EDT Wed May 24 2017 .SYNOPSIS... Upper level low digs into the Tennessee Valley and brings chances of showers today through Thursday. Unsettled again for the weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 935 AM Wednesday... Some clearing moving south to north this morning, so this should add to the convective potential today. On the fringe for the severe today with good directional shear profiles, but the instability is not as impressive. As of 230 AM Wednesday... Sfc low pressure system over KY and TN will move north into the OH Valley through tonight. A series of mid level shortwaves rotating around the upper low will produce unstable conditions for showers or storms to develop mainly across southeast OH and over the eastern mountains. Abundant cloudiness will keep temperatures in the 70s this afternoon and into the 50s tonight. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... As of 310 AM Wednesday... Upper low will be overhead on Thursday with scattered showers expected. An isolated thunderstorm is not out of the question with the cold temps aloft, but overall thunder threat is quite low. Ridging builds into the region by Friday morning and will briefly dry us out as warmer temperatures return as well. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... As of 345 AM Wednesday... The pattern is starting to take shape for Memorial Day weekend and the potential for severe thunderstorms is growing. A stationary boundary will set up from west to east across the area and current guidance is indicating several short waves moving through the zonal flow Saturday and Sunday. Deep southwesterly return flow from the Gulf of Mexico will bring a warm and moist airmass into the region. Both the Euro and GFS indicate a plume of high mid level lapse rates moving into the area on the zonal westerly flow Saturday afternoon. BUFkit soundings in the GFS indicate this EML on Saturday with very high CAPE values on forecast soundings in the order of 2000 to 2500 J/Kg and 700mb to 500mb lapse rates around 8C/km. The uncertainty lies on timing of a short wave in order to break a decent Cap and tap into this unstable air. Confidence is still rather low due to timing disagreement between the models with the arrival of the short wave. However, I think there is at least enough ingredients in place that it warrants mention here that a severe outbreak is possible. Also, instability does weaken by Sunday but strong 0-6 km bulk shear with the passing of a cold front could produce severe storms as well. Finally, PWATs will be on the rise this weekend and GEFS indicates values about 2 standard deviations above normal. With the potential for thunderstorms and low flash flood guidance values due to rains today and on Thursday, there will be potential for flash flooding to occur. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... As of 125 PM Wednesday... Showers and thunderstorms moving into the area. Restrictions in ceilings in visibilities expected to arrive in the first 6 hours of the forecast, with some IFR possible in TSRA. Have avoided TEMPO groups given the large shield of precipitation moving in as opposed to a more scattered nature of precipitation. Once the heating ends and the dry slot from the upper level low moves in, take the visibility restrictions out with enough wind in place to keep the low levels stirred. Ceilings should come down however, with some IFR under 1kft after 06Z Thursday. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z THURSDAY... FORECAST CONFIDENCE: Low. ALTERNATE SCENARIOS: Timing of TSRA or VCTS could vary. Amendments likely. Post thunderstorm environments later tonight may vary from forecast.
