CONCERNING...TORNADO WATCH 256...

VALID 050429Z - 050530Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 256 CONTINUES.

SUMMARY...THE THREAT FOR SEVERE-SIZED HAIL WILL BECOME INCREASINGLY
LOCALIZED AND THE TORNADO RISK APPEARS TO HAVE DIMINISHED
CONSIDERABLY OVER THE PAST 30-60 MINUTES.

DISCUSSION...SURFACE ANALYSIS SHOWS A SLOWLY COOLING BOUNDARY LAYER
AS INDICATED BY TEMPS FALLING INTO THE UPPER 70S NEAR I-70 IN CNTRL
KS TO THE UPPER 60S OVER NWRN KS AND S-CNTRL NEB.  THE DIURNAL
COOLING TREND COUPLED WITH EXPANDING COLD POOLS/OUTFLOW ARE
PROMOTING THE TRANSITION TO AN ELEVATED TSTM MORPHOLOGY WITH THE
PRIMARY RISK BEING LARGE HAIL.  THE SEVERE-HAIL RISK WILL PROBABLY
BECOME MORE LOCALIZED WITH TIME AS ADDITIONAL STORMS DEVELOP THEREBY
AIDING IN NEAR-SURFACE STABILIZATION.  THE TORNADO POTENTIAL HAS
DIMINISHED CONSIDERABLY ACROSS N-CNTRL KS AND...IN ABSENCE OF ANY
FURTHER SUPERCELL DEVELOPMENT...THE TORNADO THREAT WILL HAVE BECOME
EXHAUSTED IF THIS ADDITIONAL FACTOR IS NOT REALIZED.
