...THERE IS A SLGT RISK OF SVR TSTMS FROM THE UPPER OH VALLEY EWD TO
SRN NEW ENGLAND AND SEWD TO THE CAROLINAS...

...THERE IS A SLGT RISK OF SVR TSTMS PARTS OF THE NORTHERN AND
CENTRAL PLAINS...

...CENTRAL/NRN PLAINS...
LOW LEVEL MOIST SELY UPSLOPE FLOW EXPECTED TO BE SUPPORTIVE OF
REDEVELOPMENT OF SCATTERED THUNDERSTORMS FROM ND TO WRN NEB/NWRN KS
BY MID AFTERNOON. INSTABILITY EXPECTED TO BE GREATEST SRN PORTION
OF THIS AREA WITH MLCAPES UPWARDS TO 2500-3000 J/KG ALONG WITH STEEP
MID LEVEL LAPSE RATES IN EXCESS OF 8C/KM. A LITTLE LESS LOW LEVEL
MOISTURE WRN DAKOTAS HOWEVER WITH STILL STEEP LAPSE RATES WILL
PROVIDE FAVORABLE ENVIRONMENT FOR SEVERE. WITH ONLY 20-30 KT OF MID
LEVEL WESTERLY FLOW...SHEAR COUPLED WITH INSTABILITY WILL BE
SUPPORTIVE OF A FEW SUPERCELLS...HOWEVER LARGE HAIL AND DAMAGING
DOWNBURST WINDS SHOULD BE THE PRIMARY THREAT. WHILE NON-ZERO
TORNADO THREAT EXPECTED TO BE VERY LIMITED.

DURING THE EVENING 30-40 KT LOW LEVEL JET DEVELOPS CENTRAL PLAINS
WHICH WILL AID THE DEVELOPMENT OF AN MCS VICINITY WRN/CENTRAL
NEBRASKA. THIS WILL THEN MAINTAIN A THREAT OF SEVERE INCLUDING
DAMAGING WINDS WELL AFTER DARK.
