AREAS AFFECTED...EXTREME NERN KS AND EXTREME NWRN MO INCLUDING AREAS
BETWEEN KANSAS CITY AND ST. JOSEPH

CONCERNING...TORNADO WATCH 178...

VALID 212151Z - 212245Z

A POTENTIAL TORNADIC SUPERCELL WILL TRACK ESEWD ACROSS ATCHISON
COUNTY KS AND INTO AREAS BETWEEN KANSAS CITY AND ST. JOSEPH MO
THROUGH 00Z.

SRN SUPERCELL WITHIN AN ARC OF STRONG-SEVERE TSTMS WAS MOVING ACROSS
ATCHISON COUNTY KS AT 2145Z...HAVING MADE A DEVIANT RIGHT TURN SINCE
21Z.  NEARBY LTH PROFILER SHOWED AROUND 142 M2/S2 0-1KM SRH FOR THIS
SUPERCELLS MOTION.  GIVEN THAT THE WARM FRONT LIES ACROSS THE NRN
SUBURBS OF KANSAS CITY ESEWD INTO CNTRL MO...THIS STORM APPEARS TO
BE INGESTING PARCELS IN A RESERVOIR OF ENHANCED HELICITY.  LCLS ARE
A LITTLE ON THE HIGH SIDE...BUT WITH EXPANDING ANVILS DOWNSTREAM...
BOUNDARY LAYER MAY COOL AND THE CLOUD BASES MAY LOWER THE NEXT
COUPLE OF HOURS.  AS SUCH...THE TORNADO POTENTIAL IS INCREASING IN
AREAS BETWEEN ST. JOSEPH AND KANSAS CITY THROUGH 00Z. 
OTHERWISE...POTENTIALLY VERY LARGE HAIL CAN BE EXPECTED...ESPECIALLY
SWRN BUCHANAN COUNTY MO WITHIN THE FORWARD FLANK OF THE SUPERCELL.
