0306 PM CDT Sun May 26 2024
Areas affected...portions of western and southern South Dakota into
western and northern Nebraska
Concerning...Severe potential...Watch unlikely
Valid 262006Z - 262230Z
Probability of Watch Issuance...20 percent
SUMMARY...A couple instances of large hail or severe gusts are
possible through the remainder of the afternoon. Given the sparse
nature of the severe threat, a WW issuance is not expected.
DISCUSSION...Scattered multicellular/briefly transient supercellular
thunderstorms have been percolating in intensity over the past few
hours, with at least 1 report received of hail over 1 inch in
diameter. These storms are developing over marginally buoyant
airmass characterized by mainly steep low-level lapse rates. Given
limited deep-layer shear, any storm that becomes strong should only
do so for short periods of time, and a brief burst of marginally
severe hail/wind cannot be completely ruled out. Some storms may
merge cold pools later this afternoon, which may increase the severe
gust threat slightly. Nonetheless, the severe threat will be
isolated and brief at best, precluding the need of a WW issuance.
