AN ISOLATED BRIEF TORNADO/MARGINAL HAIL THREAT WILL BE POSSIBLE WITH
CLUSTER OF STG TSTMS AS THEY MOVE NWWD ACROSS SCENTRAL NEB IN THE
NEXT FEW HOURS. LIMITED/MARGINAL THREAT SHOULD PRECLUDE THE NEED FOR
A WW.

LATEST VWP DATA FROM HASTINGS INDICATED MODERATE LOW LEVEL SHEAR /15
KTS FROM 0-1 KM/ AS 30 KT SSELY 1-2 KM WINDS EXIST ABOVE ELY SFC
WINDS. A SMALL CLUSTER OF TSTMS THAT HAS DEVELOPED IN AN AREA
DIFFERENTIAL HEATING /ON THE NERN PERIPHERY OF AN UPPER LOW OVER
SWRN KS/ WILL CONTINUE TO MOVE NWWD AROUND 20 KTS THROUGH SCENTRAL
NEB. THERE EXISTS A SMALL THREAT FOR AN ISOLATED/BRIEF TORNADO WITH
THESE TSTMS OVER THE NEXT FEW HOURS AS CONTINUED HEATING WILL
SUPPORT INCREASING 0-3 KM CAPE ENHANCING LOW LEVEL VERTICAL MOTION.
RELATIVELY LIMITED DEEP LAYER VERTICAL SHEAR AND MARGINAL
INSTABILITY SHOULD PRECLUDE AN ORGANIZED SVR THREAT AND NEED FOR A
WW.
