The radar

The Wilmington radar (KLTX), 88 km from the middle of the area, began a volume at 22:13 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 severe thunderstorm 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, 10.2 hours before the alert went out and 141 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.

What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jun 23, 2:54 PM EDT, 3 hours 16 minutes earlier. Its key messages:

  • 1) Scattered Showers & Storms Possible Through This Evening. 2) Above Normal Temperatures Continue; Heat Advisory Possible This Weekend.
Area forecast discussion, Jun 23, 2:54 PM EDT, 3 hours 16 minutes before
Area Forecast Discussion
National Weather Service Wilmington NC
254 PM EDT Tue Jun 23 2026

.WHAT HAS CHANGED...
Severe Thunderstorm Watch in effect until 8PM this evening for Cape
Fear area, including the coastal waters. Small Craft Advisory end
time shifted earlier to 10PM. Discussions updated.

&&

.KEY MESSAGES...
1) Scattered Showers & Storms Possible Through This Evening.

2) Above Normal Temperatures Continue; Heat Advisory Possible
This Weekend.

&&

.DISCUSSION...
KEY MESSAGE 1...Scattered Showers & Storms Possible Through This
Evening.

A remnant MCV is currently moving eastward across central NC,
sparking convection ahead of it, including along the sea breeze.
Isolated strong to severe storms are possible given the abundant
heat and humidity in place, supporting plenty of instability while
modest wind shear helps with storm organization. While the most
supportive conditions for severe storms exist north of the area, a
Severe Thunderstorm Watch was raised for the Cape Fear area as
plenty of instability and greater DCAPE exist with southward extent,
which may help offset the weaker effective shear (~20 kts) this far
south. Behind the MCV, a mid-level shortwave trough will send a cold
front southward, serving as a lifting mechanism which should be able
to spark isolated to scattered showers and storms later this
afternoon into this evening, mainly near the boundary. Once again,
any severe storms should be isolated and relatively short-lived due
to the weak vertical wind shear. Nevertheless, convection associated
with the front will gradually shift southeastward into the Pee Dee
region and dissipate into tonight, with cooler and drier air
filtering in overnight.

KEY MESSAGE 2...Above Normal Temperatures Continue; Heat Advisory
Possible This Weekend.

Behind Tuesday's cold front, near-normal temperatures and dry
conditions are expected for Wednesday and Thursday. Expect
highs in the upper 80s to near 90 on Wednesday and lower 90s on
Thursday.

For Friday through this weekend, significant heat is anticipated as
ridging over the Atlantic pushes back into the South. Triple digit
heat indices return on Friday and rise considerably over the
weekend, with Heat Advisories possible as max temperatures push into
the mid-upper 90s and overnight lows settle only into the mid-upper
70s. Prepare to limit time outdoors and drink plenty of water!

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Gusty winds are affecting the terminals this afternoon ahead of a
cold front and isolated showers and storms will continue to pass
near or over the NC terminals for at least the next hour or two,
with brief restrictions possible. A cold front is expected to push
southward later this afternoon with a broken line of showers and
storms possible along it, bringing brief restrictions to the
terminals back into the picture into this evening while gusty winds
subside. After the showers and storms dissipate or move offshore,
expect a quiet night with mainly clear skies and light north winds
as cooler and drier air filters in. Fog is unlikely due to the
incoming dry air and expectation for winds to continue through the
night. However, if KLBT sees enough rain today and winds become calm
for long enough to support shallow fog late in the night, there may
be short-lived MVFR restrictions.

Extended Forecast...Mostly VFR through Sunday. The exceptions would
include a low potential for fog Thursday and Friday mornings, and
some slightly better convection chances Sunday.

&&

.MARINE...
The Small Craft Advisory is in effect until 10PM EDT this evening
for the coastal waters from Surf City, NC to South Santee River, SC
out to 20 nm. Gradient winds out of the southwest will continue with
gusts up to 25-30 kts until late afternoon. Seas peak around 5-7 ft
late this afternoon before subsiding this evening. A cold front
moves through the waters late tonight, allowing the winds to veer to
the NNW and settle around 10-15 kts. Seas also improve to 2-4 ft
early Wednesday.

With high pressure in control over land behind the cold front, winds
settle to 10 kts or less for Wednesday night through Friday
morning. Seas subside to 1-3 ft amidst the light winds. Bermuda
high pressure then takes over and abnormally hot temperatures
over land help to tighten the pressure gradient, leading to a
breezy Friday and Saturday with sustained winds as high as 15-20
kts and seas rising to 3-5 ft.
