       NORTH CENTRAL KANSAS

EFFECTIVE THIS FRIDAY NIGHT FROM 650 PM UNTIL MIDNIGHT CDT.

TORNADOES...HAIL TO 3 INCHES IN DIAMETER...THUNDERSTORM WIND
GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE

RUSSELL KANSAS TO 45 MILES NORTH OF RUSSELL KANSAS.  FOR A

TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH

VERTICAL SHEAR TO THE NORTH OF THE WARM FRONT...COUPLED WITH HIGH
CAPE VALUES WILL PROMOTE THE RISK OF INTENSE SUPERCELLS CAPABLE OF
LARGE HAIL AND DAMAGING WINDS.  ISOLATED TORNADOES ARE ALSO
POSSIBLE...ALTHOUGH A MITIGATING FACTOR IS THE WARM TEMPERATURES IN
THE EML AND RATHER WEAK LOW LEVEL CAPE VALUES.
