Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Newport, NC (KMHX), launched 12:00Z, 7.5 hours before the alert went out and 146 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

22What 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 Raleigh, NC wrote its last area forecast discussion before this flash flood warning went out at Aug 21, 2:45 PM EDT, 42 minutes earlier. Its key messages:
- As of 245 PM Friday... 1) There is a risk of excessive rainfall across the entire forecast area, primarily during the afternoon and early evening. 2) There is a risk of severe thunderstorms across the entire forecast area this afternoon and evening, with the greatest threat along and south of US-64.
Area forecast discussion, Aug 21, 2:45 PM EDT, 42 minutes before
Area Forecast Discussion National Weather Service Raleigh NC 245 PM EDT Fri Aug 21 2026 .WHAT HAS CHANGED... * Severe Thunderstorm Watch issued for southern counties this afternoon. * Flood watch expanded to Anson county. && .KEY MESSAGES... As of 245 PM Friday... 1) There is a risk of excessive rainfall across the entire forecast area, primarily during the afternoon and early evening. 2) There is a risk of severe thunderstorms across the entire forecast area this afternoon and evening, with the greatest threat along and south of US-64. && .DISCUSSION... As of 245 PM Friday... KEY MESSAGE 1... There is a risk of excessive rainfall across the entire forecast area, primarily during the afternoon and early evening. The Weather Prediction Center has the entire forecast area under a slight (level 2 of 4) risk for excessive rainfall. Locally, a flood watch was issued overnight for much of the area, excluding the Triad and areas northeast of the Triangle, going through Saturday morning. A boundary is set up across southern counties, having pushed slightly farther south than anticipated. From Sanford and Erwin to the northeast, low clouds and northerly flow have kept temperatures primarily in the 70s, while out in the Triad and southern counties, more sun has allowed for temperatures to climb in the 80s and lower 90s. While convective-allowing models have performed poorly over the last day or two, there are still indications that thunderstorms currently developing along the North Carolina/South Carolina border will expand in coverage and push to the north during the afternoon. With slow storm movement, deep moisture, and "skinny CAPE", these storms will have the potential to bring multiple inches of rain in a short period of time. In particular, the 12Z HREF shows approximately a 50% potential for 3 inches of rain in 3 hours just to the south of the Triangle during the late afternoon. Showers and thunderstorms will likely peak in coverage before sunset, continue into the evening, then rapidly drop off after midnight. KEY MESSAGE 2... There is a risk of severe thunderstorms across the entire forecast area this afternoon and evening, with the greatest threat along and south of US-64. The Storm Prediction Center has placed the Triad and counties along the VA/NC border in a marginal (level 1 of 5) risk, with the rest of the forecast area in a slight (level 2 of 5) risk. The primary threat is damaging winds, although large hail cannot be ruled out. As of 2pm, there is minimal MLCAPE and large amounts of CIN along and to the north of US-64, while the greatest instability is to the south of the boundary that was discussed in Key Message 1. That is the primary reason that the Severe Thunderstorm Watch that was issued around 1:30pm only included the southern half of the forecast area and did not extend any farther to the north. Across Cumberland and Sampson counties, the MLCAPE is as high as 3000 J/kg. There is at least 30 kt of effective bulk shear across the forecast area, which should help to eventually organize storms. The greatest threat for severe thunderstorms should be over the next several hours, and the Severe Thunderstorm Watch is valid through 9pm. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... As of 145 PM Friday... TAF period: Confidence is lower than normal in the details of these TAFs due to the uncertainty with thunderstorms and where they will develop today; however, confidence is high that all terminals will experience at least some rain this afternoon and have low ceilings overnight. Thunderstorms are beginning to develop along the North Carolina/South Carolina border and will increase in coverage as they move northeast. Have gone with prevailing showers at all sites, continuing a TEMPO group during the most likely 4 hour window for thunderstorms. Visibility reductions with the storms may be slightly greater than normal considering heavy rain rates are expected today. There is a bit of uncertainty as to how long the prevailing rain will last into this evening, but IFR ceilings are likely to quickly expand from INT/GSO south and east after dark, with all sites expected to eventually develop LIFR ceilings. The ceilings should lift to MVFR by late Saturday morning, with scattered showers developing by that time at RDU/FAY/RWI. Outlook: Precipitation will primarily be at RDU/FAY/RWI Saturday afternoon, although it cannot be ruled out at INT/GSO. Widespread restrictions are not currently forecast for any sites Saturday night, although if precipitation is heavy enough, there could be local restrictions. Dry VFR conditions are expected Sunday through Tuesday night before a chance of thunderstorms returns to all terminals Wednesday. && .RAH WATCHES/WARNINGS/ADVISORIES...
