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 Aug 15, 2:21 PM EDT, 5 hours 26 minutes earlier.
Area forecast discussion, Aug 15, 2:21 PM EDT, 5 hours 26 minutes before
AREA FORECAST DISCUSSION National Weather Service Charleston WV 221 PM EDT Sun Aug 15 2021 .SYNOPSIS... Stalling front brings isolated to scattered storms today. With an abundance of moisture ahead of, and then with, Fred, the chance for locally heavy rain persists into midweek. && .NEAR TERM /THROUGH MONDAY/... As of 140 PM Sunday... Surface high pressure backs off through today allowing the meandering front to our south to retrograde some. This will support increasing chances of convection throughout the rest of the day, especially over the higher elevation areas, and chances will stay elevated enough to make it possible for an isolated storm even for the overnight. Anomalously high PWATs will exist through the period which will fuel the potential for heavy downpours or prolonged steady rainfall under convection which will consequently entertain the possibility of flash flooding to low lying or flood prone areas. Chances for showers and storms ramp up again for the daytime on Monday as the Bermuda high continues to funnel in moisture from the deep south. Even though temperatures will only increase to around 5 degrees below normal, showers and storms will remain on tap through the day. Storms will generally be sub-severe although the threat that will remain on the table within storms will be flash flooding, especially with any backbuilding or training cells. This will be the main theme through the rest of this period and beyond as the area becomes primed very well from recent rainfall amounts and future amounts which will continue to lower flash flood guidance over the area. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 215 PM Sunday... Overall little change in the forecast thinking in the short term period. Moisture streaming north from remnants of Fred on Tuesday, with Fred moving over the area on Wednesday. Anomalously high moisture content associated with remnants of Fred will create a good soaker across the region, with a general 2 to 4 inches of rain expected. Area continues to remain in a slight risk for excessive rainfall, and a flood watch may be necessary in future shifts, but for now, will continue to monitor the situation, especially with abnormally dry conditions continuing across the area at this time. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 220 PM Sunday... Extended period remains unsettled with multiple upper shortwaves crossing the area. Showers and storms will continue at times, particularly during peak heating hours in the humid, unstable conditions. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 140 PM Sunday... Light northeasterly flow switches over to southerly by overnight. Chances of isolated thunderstorms will remain through the period as plenty of moisture is funneled into the area along with a meandering frontal boundary along our south. The majority of the time, borderline MVFR CIGs will prevail along with showers and MVFR reductions to VIS. At times, IFR VIS/CIGs will make an appearance, especially in the late morning at most terminals since fog will likely form over any area that was previously saturated from the daytime. Chances are slim for overnight storms although we cannot rule them out, however the chances will increase for Monday afternoon. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: None. 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.
