THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 664
CONTINUES.

STORMS CONTINUE TO VACATE WW 664. DOWNSTREAM WATCH NOT ANTICIPATED.

SEVERE THREAT IS FORECAST TO SLOWLY DIMINISH WITH TIME AS DIURNAL
STABILIZATION CONTINUES. THREAT WILL LIKELY LINGER THE LONGEST
ACROSS PARTS OF NRN ID AND PARTICULARLY INTO A SMALL PORTION OF NWRN
AND FAR WRN MT...WHERE A SMALL MCS IS ONGOING AHEAD OF THE MAIN
UPPER CYCLONIC VORTICITY CENTER. THOUGH DEEP-LAYER WIND FIELD
REMAINS SUPPORTIVE FOR ORGANIZED/SEVERE STORMS AHEAD OF THIS
ENEWD-MOVING CLUSTER...BOUNDARY-LAYER STABILIZATION SHOULD
EVENTUALLY LIMIT THE POTENTIAL FOR DAMAGING WINDS AT THE SURFACE.
