VALID 210204Z - 210300Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 276
CONTINUES.

SUMMARY...THE RISK FOR DAMAGING WIND AND LARGE HAIL APPEARS TO BE
DIMINISHING...AND WW 276 COULD BE CANCELED PRIOR TO THE SCHEDULED
04Z EXPIRATION.

DISCUSSION...THUNDERSTORMS HAVE SPREAD SWD AHEAD OF THE COLD
FRONT...AND HAVE WEAKENED GRADUALLY OVER THE PAST 1-2 HOURS.  GIVEN
THE LOSS OF DAYTIME HEATING...SLOW STABILIZATION OF THE BOUNDARY
LAYER WILL CONTRIBUTE TO A DECREASE IN BUOYANCY...AND CONTINUED
GENERAL WEAKENING OF THE STORMS.  AS SUCH...THE SEVERE STORM RISK
APPEARS TO BE DIMINISHING...AND WW 276 COULD BE CANCELED PRIOR TO
THE 04Z EXPIRATION TIME.
