The severe weather threat for Severe Thunderstorm Watch 199
SUMMARY...Locally strong wind gusts are possible in portions of
central Nebraska. A relatively greater threat for strong/severe wind
gusts will be in northwest Kansas and far southwest Nebraska where
instability remains slightly higher.
DISCUSSION...The line of thunderstorms has weakened in north-central
Nebraska where more limited buoyancy and increasing inhibition
exist. Strong cold-pool driven gusts will remain possible for
perhaps an hour or two more. Farther south into northwest Kansas,
greater instability is evident on objective mesoanalysis. A
relatively greater threat for strong/severe wind gusts will exist
across this region. Given storm mode, marginally severe hail will be
quite isolated if it occurs. The overall trend, though, will be for
storms to continue to decrease in intensity over the next few hours
as inhibition continues to increase to the east.
