NWS STORM PREDICTION CENTER NORMAN OK
0545 PM CDT FRI SEP 27 2013

AREAS AFFECTED...NORTHERN KS...CENTRAL NEB

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 272245Z - 272345Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...SCATTERED THUNDERSTORMS OVER NORTH-CENTRAL KS WILL TRACK
NORTHEASTWARD INTO CENTRAL NEB THIS EVENING. ISOLATED SEVERE STORMS
ARE POSSIBLE WITH DAMAGING WINDS THE MAIN THREAT.

DISCUSSION...A BROKEN LINE OF STRONG THUNDERSTORMS HAS FORMED ALONG
A PRE-FRONTAL BOUNDARY EXTENDING FROM LANE COUNTY KS NORTHWARD INTO
RED WILLOW/FURNAS COUNTIES NEB. THESE STORMS ARE MOVING
NORTHEASTWARD AT 35-40 KNOTS AND WILL LIKELY TRACK INTO
SOUTH-CENTRAL NEB DURING THE NEXT FEW HOURS. A CORRIDOR OF MARGINAL
SURFACE-BASED INSTABILITY IS PRESENT AHEAD OF THE STORMS...
SUGGESTING SOME RISK OF DAMAGING WIND GUSTS REACHING THE GROUND IN
THE STRONGEST STORMS. WINDS FIELDS ARE RELATIVELY STRONG...POSING
THE POTENTIAL FOR ROTATING STORMS CAPABLE OF HAIL AS WELL. THE
GREATEST RISK WILL LIKELY BE ASSOCIATED WITH THE STORM OVER NORTON
COUNTY KS AS IT TRACKS ROUGHLY ALONG THE SURFACE BOUNDARY NEAR AND
WEST OF GRAND ISLAND DURING THE NEXT COUPLE OF HOURS. WE ARE
MONITORING FOR INCREASING COVERAGE OF SEVERE THREAT AND A POSSIBLE
WW.
