May 18, 2026 · NWS FSD · 4 events in 1 county or zone

A slow moving frontal boundary from northeast Nebraska into northwest Iowa focused development of scattered thunderstorms during the late afternoon and very early evening. Storms fired and intensified with elevated instability above a stratus layer around 1000-1500 J/kg and 40-50 knots of effective shear.

What happened

The episode as NWS FSD wrote it up.

A slow moving frontal boundary from northeast Nebraska into northwest Iowa focused development of scattered thunderstorms during the late afternoon and very early evening. Storms fired and intensified with elevated instability above a stratus layer around 1000-1500 J/kg and 40-50 knots of effective shear. Stronger and more organized cells produced large hail up to golf ball size.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Sioux Falls, SD wrote its last area forecast discussion before the first event at May 18, 12:01 PM CST, 3 hours 17 minutes earlier. Its key messages:

  • Showers and isolated thunderstorms return to the area this afternoon this evening into tonight.
  • A few storms along and southeast of a Wayne to Sheldon to Windom line may be strong to severe late this afternoon into this evening. The main threat would be hail to half dollar size but storms this strong should remain very isolated and likely closer to near and east of Highway 60.
  • Areas of frost or freeze will be possible on Wednesday morning, with the better chances north of I-90.
  • Cool conditions prevail this week. Dry weather expected mid week. Another round of storms is possible Thursday through Friday.

.DISCUSSION...
Issued at 1258 PM CDT Mon May 18 2026

Early this afternoon the surface to 925 mb front was across southern
NE into southern IA. Given the marginal strength of the incoming
wave, this boundary should not lift far enough north and west
by late afternoon to get into the area. This should limit any
wind and tornado threats and keep them off to the southeast.
However, some elevated hailers will remain possible across
mainly northwest IA as elevated CAPE values ramp up to about
1000-1500 J/KG and deep layer shear is a fairly strong,
unidirectional 40-50 knots. This would be lifting a parcel from
above the stratus layer, which would likely be in about the
800-750mb layer. The better chances will be from about 5 pm to 9
pm.

After this wave pushes the remaining instability out of the area
this evening, dry and cool conditions are expected for Tuesday and
Wednesday. The only concerns on these two days will be the potential
for frost and freeze conditions, mostly north of I-90, as surface
high pressure is in place. Another weaker wave moves through the
area on Wednesday but for now this appears to bring mainly mid level
cloud cover.

The next better chance for showers and thunderstorms will come
Thursday night into Friday night. At this time severe weather looks
to remain isolated as model instability fields are hinting at 1000
J/kg CAPE or less for the most part.

Once this wave passes a warming trend should move in as flat ridging
aloft develops ahead of a deepening low pressure in the Northern
Rockies. Saturday should be mild, likely in the 70s, while Sunday
sees the better chance to warm into the 80s.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1243 PM CDT Mon May 18 2026

Widespread stratus, mai.nly IFR but occasionally MVFR, will
persist through much of the night, but gradually improve later
tonight into Tuesday morning. Scattered showers and isolated
thunderstorms will increase in coverage through the afternoon
into the early evening, then gradually diminish through the
early overnight hours. The strongest thunderstorms will be in
parts of northwest IA, with the better chance from 5 pm through
9 pm. A few of these storms could contain hail.
