1233 PM CDT Tue Aug 15 2017

Areas affected...Much of central and eastern Nebraska

Concerning...Severe potential...Watch unlikely

Valid 151733Z - 151900Z

Probability of Watch Issuance...20 percent

SUMMARY...A threat of isolated severe hail may persist for a couple
hours across central and northeast Nebraska.

DISCUSSION...Several storms have rapidly formed north of an outflow
boundary/warm front, aided by southerly sfc to 850 mb flow with
theta-e advection out of KS. While this general area of low-level
warm advection will persist throughout the day, these winds will
begin to focus more into western NE later this afternoon where
additional severe storms are expected. Until then, periodic severe
hail cores are expected over central into northeast NE in the near
term.
