PLAINS...
...THERE IS A SLGT RISK OF SVR TSTMS FROM THE TN VALLEY EWD TO
COASTAL NC...
...ROCKIES/HIGH PLAINS...
THUNDERSTORMS CONTINUE ATTM FROM ERN WY SWD INTO NERN NM...WITHIN
ZONE OF LIFT ASSOCIATED WITH LOW-LEVEL UPSLOPE FLOW. SUFFICIENT
INSTABILITY /1000 TO 1500 J/KG CAPE/ COMBINED WITH SHEAR
MARGINALLY-SUPPORTIVE OF SUPERCELLS SUGGESTS THAT THREAT FOR HAIL
AND/OR LOCALLY-DAMAGING WINDS WILL CONTINUE. THREAT MAY LINGER INTO
THE OVERNIGHT HOURS...AS INTENSIFYING SELY LOW-LEVEL JET SHOULD
SUPPORT AN INCREASE IN CONVECTIVE COVERAGE THIS EVENING...THOUGH ERN
EXTENT OF THREAT INTO THE PLAINS WILL BE LIMITED BY A LACK OF
INSTABILITY FROM N CENTRAL KS NWWD INTO THE WRN DAKOTAS.
...TN VALLEY EWD TO THE NC COAST...
TWO MAIN CLUSTERS OF STRONG/SEVERE STORMS -- ONE MOVING ACROSS
CENTRAL KY AND THE OTHER OVER CENTRAL AND ERN NC -- ARE ONGOING
ATTM...WITHIN BELT OF MODERATE WLY MID-LEVEL FLOW. STORMS OVER KY
APPEAR TO BE BUILDING WWD INTO WRN TN...WITHIN ZONE OF LOW-LEVEL
CONVERGENCE ALONG SURFACE FRONT. AMPLE INSTABILITY SUGGESTS THAT
STORMS SHOULD CONTINUE -- POSSIBLY THROUGH THE REMAINDER OF THE
EVENING...ACCOMPANIED BY A CONTINUED THREAT FOR LOCALLY-DAMAGING
WINDS AND/OR HAIL. OVERALL SEVERE POTENTIAL SHOULD WANE WITH TIME
LATER THIS EVENING...WITH LITTLE THREAT ANTICIPATED OVERNIGHT.
...SRN ID AND VICINITY...
ISOLATED THUNDERSTORMS HAVE DEVELOPED ACROSS SRN ID...IN
MARGINALLY-UNSTABLE/MODERATELY-SHEARED ENVIRONMENT. THOUGH
SHORT-WAVE RIDGE IS FORECAST TO AMPLIFY ACROSS THIS REGION

THREAT -- MAY PERSIST FOR A FEW MORE HOURS.
