0144 PM CDT SAT APR 14 2012
AREAS AFFECTED...CNTRL/WRN KS
CONCERNING...TORNADO WATCH 165...
VALID 141844Z - 141945Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 165 CONTINUES.
THE THREAT FOR SIGNIFICANTLY TORNADIC SUPERCELLS IS INCREASING OVER
PARTS OF SWRN KS INCLUDING THE DODGE CITY AREA. INFLOW INTO DISCRETE
SUPERCELLS EVOLVING OVER MEADE AND GRAY/FORD COUNTIES IS LIKELY
BECOMING SURFACE BASED PER MODIFIED RUC/OBSERVED SOUNDINGS. SBCAPE
VALUES OF 2000-3000 J/KG AMIDST STRONG DEEP-LAYER SHEAR WILL SUPPORT
RAPID INTENSIFICATION WITH THESE STORMS. STRONG LOW-LEVEL SHEAR --
0-1 KM SRH OF 297 M2/S2 PER HAVILAND KS PROFILER THAT ALSO INDICATES
A LARGE AMOUNT OF STREAMWISE VORTICITY CONCENTRATED IN THE LOWEST
0.5 KM AGL -- COULD SUPPORT SIGNIFICANT TORNADOES. ADDITIONAL
CLUSTERS OF STORMS INCLUDING SUPERCELLS FARTHER NORTH ACROSS THE WW
AREA WILL POSE MAINLY A LARGE/VERY LARGE HAIL THREAT AND PERHAPS A
COUPLE OF TORNADOES BEFORE A MORE FAVORABLE THERMODYNAMIC
ENVIRONMENT FOR SFC-BASED SUPERCELLS ARRIVES WITHIN A FEW HOURS.
