VALID 270335Z - 270500Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 65
CONTINUES.
SUMMARY...WIDESPREAD CONVECTION AND EMBEDDED WEAK THUNDERSTORM
ACTIVITY LINGERS, BUT THE POTENTIAL FOR SEVERE WEATHER APPEARS
UNLIKELY TO INCREASE. SEVERE THUNDERSTORM WATCH 65 MAY BE ALLOWED
TO EXPIRE AT 9 PM PDT.
DISCUSSION...CONVECTIVE DEVELOPMENT, AND EMBEDDED WEAK THUNDERSTORM
ACTIVITY, PERSISTS ALONG THE WESTERN SLOPES OF THE OREGON CASCADES.
HOWEVER, THE PRIMARY CLUSTER OF THUNDERSTORM ACTIVITY IS NOW RAPIDLY
SPREADING WITH THE MORE FAVORABLE MID/UPPER FORCING FOR ASCENT
ACROSS AND NORTH-NORTHWEST OF THE PUGET SOUND VICINITY. LOCALLY
STRONG SURFACE GUSTS MIGHT STILL BE POSSIBLE, BUT THERMODYNAMIC
PROFILES CHARACTERIZED BY RATHER MODEST TO WEAK MID/UPPER LAPSE
RATES, AND MORE LIMITED LOW-LEVEL MOISTURE THAN SOME MODEL GUIDANCE
INDICATED, APPEAR TO HAVE MITIGATED THE SEVERE WEATHER THREAT.
