06/25/2026 Laramie WY Trained Spotter
Photos from several trained spotters and
chasers show a rotating wall cloud with a
short funnel underneath/behind this feature
lasting 2-3 minutes. Other photos of a
possible landspout were determined to be a
hail shaft ahead of the gust front. No
ground circulation was visible in the
photos, possibly due to wet grass/prairie
despite strong rotation of the wall cloud.
