.SOUNDING DISCUSSION...

THE 00Z SOUNDING IS VERY UNSTABLE...AND SHOWS A THERMODYNAMIC
PROFILE THAT IS CONDUCIVE TO HIGH WIND EVENTS. THE SOUNDING HAS A
CLASSIC HOURGLASS SHAPE AS A LAYER OF DRIER AIR BETWEEN 850 AND
700MB RESIDES JUST ABOVE THE LIFTED CONDENSATION LEVELS. STEEP
NEARLY DRY ADIBATIC LAPSE RATES BELOW 500MB AND A LOW WET BULB
ZERO HEIGHT OF 11.6K FEET WERE ALSO NOTED. WITH A HAIL CORE LIKELY
MELTING AS IT DESCENDS...AND DRY AIR ENTRAINING INTO THE DOWNDRAFT
IN THE MID- LEVELS...THE DOWNDRAFT COOLED AND TURNED MORE DENSE.
THIS WOULD INCRAESE DOWNWARD MOMENTUM OF THE DOWNDRAFT AND RESULT
IN STRONGER WINDS AT THE SURFACE. THIS WAS NOTED BY LOCALIZED
WIND DAMAGE REPORTS WITH THE STRONGEST STORMS TODAY.
