The radar

The Columbia radar (KCAE), 108 km from the middle of the area, began a volume at 22:46 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

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

Charleston AFB, SC (KCHS), launched 12:00Z, 10.7 hours before the alert went out and 169 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.

expected. Flash flooding likely is ongoing.

What 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 Wilmington, NC wrote its last area forecast discussion before this flash flood warning went out at Aug 3, 4:53 PM EDT, 1 hour 51 minutes earlier. Its key messages:

  • 1) Unsettled weather pattern continues, with scattered to numerous showers and storms likely through at least midweek.

.WHAT HAS CHANGED...
Updated discussions below.

&&

.KEY MESSAGES...
1) Unsettled weather pattern continues, with scattered to
numerous showers and storms likely through at least midweek.

&&

.DISCUSSION...
.KEY MESSAGE 1...Unsettled weather pattern continues, with
scattered to numerous showers and storms likely through at least
midweek.

Showers and storms will continue into tonight with heavy rain
possible. A similar pattern looks to continue into midweek. Isolated
flooding could be possible should slow-moving, heavy rainfall move
over the same areas for several hours. Things will start to shift
into the latter half of the week and the weekend as less mid-level
energy traverses the area and high pressure attempts to build
in.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
Varying levels of restrictions expected through the TAF period. At
least MVFR stratus will stick around with worsening conditions late
tonight as another round of rain pushes over the area. This could
also be mixed with low stratus/fog, particularly at inland
terminals. Activity will then shift back towards the coast come
Tuesday morning, similar pattern to today.

Extended Forecast...Periodic sub-VFR restrictions will be possible
in showers and thunderstorms through at least Wednesday. The moist
low-level airmass will also support a greater potential for morning
stratus each day. Widespread VFR might return late week.

&&

.MARINE...
6 ft waves may linger near 20 nm out but otherwise conditions within
20 nm will fall below Small Craft Advisory thresholds. Shower/storm
activity will remain possible overnight with reduced visibility in
heavy rain. Sub-SCA conditions thereafter for the remainder of the
week with S/SE flow as Bermuda high pressure is locked in place off
to the east, but periodic heavy rainfall may linger through
midweek.

&&

.ILM WATCHES/WARNINGS/ADVISORIES...
NC...High Risk for Rip Currents until 8 PM EDT this evening for NCZ106-
     108-110.
SC...High Risk for Rip Currents until 8 PM EDT this evening for SCZ054-
     056.
