THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 452
CONTINUES.

SUMMARY...ONGOING SEVERE TSTMS WILL CONTINUE TO POSE A RISK OF
SEVERE HAIL AND WIND FOR THE NEXT 1-2 HRS. SPATIAL/TEMPORAL
EXTENSION OF WW 452 MAY BECOME NECESSARY BEFORE 00Z ACROSS SRN

ERN PART OF WW 452...WITH A LONG-LIVED CELL NOTED IN OXFORD CO.
MAINE AND A BOWING SEGMENT APPROACHING PWM. CONVECTION WILL LIKELY
CONTINUE INTO THE EVENING AHEAD OF THE STRONG VORT MAX MOVING INTO
NRN NEW ENGLAND...BUT THE SEVERE THREAT IS EXPECTED TO DIMINISH WITH
ERN EXTENT...WHERE SURFACE-BASED INSTABILITY BECOMES QUITE MINIMAL
IN AN AREA DOMINATED BY LOW CLOUDINESS AND COOL SELY FLOW OFF OF THE
ATLANTIC. AS A RESULT...ADDITIONAL WW ISSUANCE IS NOT
ANTICIPATED...BUT SPATIAL/TEMPORAL EXTENSION OF WW 452 MAY BE
NECESSARY BEFORE 00Z TO COVER THE REMAINING SHORT-TERM THREAT
DOWNSTREAM OF THE ONGOING CONVECTION ACROSS SRN MAINE. T
