AREAS AFFECTED...CNTRL KS...SE NEB

CONCERNING...TORNADO WATCH 136...

VALID 070417Z - 070545Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 136 CONTINUES.

SUMMARY...AN ISOLATED SEVERE THREAT IS EXPECTED TO CONTINUE FOR A
FEW MORE HOURS ACROSS SE NEB WHERE LARGE HAIL AND STRONG WIND GUSTS
MAY OCCUR. A TORNADO CAN NOT BE RULED OUT IN SE NEB. THE SEVERE
THREAT ACROSS CNTRL KS APPEARS TO BE DIMINISHING.

DISCUSSION...THE LATEST SFC ANALYSIS SHOWS A TROUGH OF LOW PRESSURE
FROM WRN KS NWD INTO CNTRL NEB WITH A COLD FRONT LOCATED IN WRN NEB.
A ZONE OF LOW-LEVEL CONVERGENCE IS PRESENT ACROSS NRN KS EXTENDING
NEWD INTO SE NEB WHERE A LINE OF STRONG TO SEVERE THUNDERSTORMS IS
ONGOING. THIS CONVECTION IS NEAR THE AXIS OF A 50 TO 65 KT LOW-LEVEL
JET. THIS FEATURE ALONG WITH MODERATE DEEP-LAYER SHEAR EVIDENT ON
THE HASTINGS WSR-88D VWP SUGGESTS THAT A SEVERE THREAT MAY CONTINUE
FOR A FEW MORE HOURS. THE SHEAR ENVIRONMENT SHOULD SUPPORT ROTATING
STORMS EMBEDDED IN THE LINE WITH A HAIL AND POSSIBLY AN ISOLATED
TORNADO THREAT.

FURTHER SOUTH ACROSS CNTRL KS...RADAR TRENDS SUGGEST THAT THE SEVERE
THREAT IS DIMINISHING. ALTHOUGH HAIL AND STRONG WIND GUSTS COULD
STILL OCCUR OVER THE NEXT HOUR NEAR THE OK-KS STATE-LINE...WW 136
COULD POSSIBLY BE CANCELED EARLY FOR PARTS OF SCNTRL KS.
