Concerning...Severe Thunderstorm Watch 397...
Valid 080212Z - 080345Z
The severe weather threat for Severe Thunderstorm Watch 397
continues.
SUMMARY...Severe gusts of 70-80 mph and isolated large hail remain
possible with a southward-moving complex of storms in Severe
Thunderstorm Watch 397.
DISCUSSION...Latest radar data from KUEX shows a gradually
upscale-growing complex of storms tracking southward at around 30-35
kt across south-central Nebraska. While a consolidated cold pool
appears to be intensifying, intense/separated supercell structures
remain evident along/immediately behind the gust front. Given these
persistent separated supercells and a favorable supercell wind
profile downstream (upwards of 70 kt of effective shear and a
large/looping hodograph), instances of large to very large hail up
to around 2.75 inches remain possible in the near term. However, the
overall severe risk should be transitioning to a damaging-wind
threat, owing to the gradual upscale growth. This upscale growth
should be aided by increasingly orthogonal deep-layer shear to the
consolidated cold pool and a strengthening southerly low-level jet
(around 40 kt sampled by downstream VWP). If more robust upscale
growth does occur, 70-80 mph gusts could become more common.
