CONCERNING...TORNADO WATCH 206...

VALID 250216Z - 250345Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 206 CONTINUES.

SUMMARY...THE THREAT FOR LARGE HAIL AND A FEW DAMAGING WIND
GUSTS...AS WELL AS A TORNADO OR TWO...CONTINUES PRIMARILY ACROSS FAR
SRN PORTIONS OF WW 206.

DISCUSSION...THE 02Z WSR-88D MOSAIC EXHIBITS A PAIR OF SUPERCELLS
OVER SEWARD CO KS. MEANWHILE...A BAND OF CONVECTION FROM WICHITA CO
TO STANTON CO /WITH AN EMBEDDED MESOVORTEX ON THE NRN END/ CONTINUES
TO PROGRESS EWD. ADDITIONALLY...AN EMBEDDED SUPERCELL APPEARS TO
HAVE EVOLVED WITHIN THE SRN END OF THIS LINE. NRN PORTIONS OF THIS
LINEAR SYSTEM HAVE WEAKENED OVER THE LAST HOUR...BUT THE
AFOREMENTIONED CELLS TO THE SOUTHEAST /AS WELL AS THE TAIL-END
SUPERCELL/ ARE CONTINUING TO SUPPORT A THREAT FOR LARGE
HAIL...DAMAGING WINDS...AND A COUPLE OF TORNADOES. WHILE NOCTURNAL
COOLING HAS COMMENCED AND THE 00Z DDC RAOB SAMPLED SOME MLCIN AROUND
750-700 MB /INDICATIVE OF A MORE HOSTILE THERMODYNAMIC ENVIRONMENT
TO THE EAST/...UPDRAFT ORGANIZATION/ROTATION AIDED BY STEEP
MID-LEVEL LAPSE RATES AND A VEERING 0-3-KM WIND PROFILE MAY MAINTAIN
CONVECTIVE INTENSITY VIA DYNAMIC PRESSURE PERTURBATION PROCESSES.
INDEED...SEVERAL REPORTS OF LARGE HAIL /INCLUDING A 3-INCH REPORT/
IN SEWARD CO HAVE BEEN RECEIVED. AS SUCH...THE SEVERE THREAT
CONTINUES ACROSS SRN PORTIONS OF WW 206. WHILE CELLS WILL LIKELY
WEAKEN AS THEY PROGRESS EAST...A LOCAL AREAL EXTENSION BY A TIER OF
COUNTIES EWD MAY BE NECESSARY IF CELLS MAINTAIN THEIR CURRENT
INTENSITY.
