...SYNOPSIS...
A LOW AMPLITUDE SHORTWAVE TROUGH WILL MOVE ACROSS THE NRN PLAINS IN
ADVANCE OF THE LARGER AMPLIFICATION FARTHER W...AND WILL BRING A
COLD FRONT SEWD TO A SRN MN TO CNTRL NEB LINE BY LATE AFTERNOON.
THIS FRONT WILL CONTINUE SWD INTO KS OVERNIGHT...AND WILL PROVIDE A
FOCUS FOR SCATTERED STRONG STORMS WITH A MARGINAL HAIL AND WIND
THREAT FROM NEB/KS INTO IA AND MN.

...NEB/KS INTO IA AND SRN MN...
HEATING AHEAD OF THE FRONT AND MOISTURE ADVECTION WILL RESULT IN
MARGINAL INSTABILITY WITH STORMS EASILY FORMING ALONG THE FRONT BY
MID/LATE AFTERNOON...INITIALLY FROM NRN NEB INTO SERN SD. WHILE SOME
LOW LEVEL VEERING OF THE WIND PROFILES WILL PERSIST...FLOW ALOFT
WILL BE MARGINAL AND HODOGRAPHS SUGGEST MAINLY SEWD PROPAGATING
MULTICELLS. A FEW OF THE STRONG UPDRAFTS COULD PRODUCE MARGINALLY
SEVERE HAIL ESPECIALLY DURING THE DAY...AND GUSTY WINDS WILL ALSO BE
LIKELY DURING THE EVENING WITH BACK BUILDING STORMS SUPPORTED BY A
SWLY LOW LEVEL JET.
