CONCERNING...SEVERE THUNDERSTORM POTENTIAL...

VALID 301911Z - 302200Z

CONVECTIVE TRENDS ARE BEING MONITORED FOR POSSIBILITY OF WW.

CLUSTER OF STORMS APPEARS TO BE INCREASING/ORGANIZING SOUTHEAST OF
MONTPELIER VT...EMBEDDED WITHIN MODERATELY SHEARED 30 TO 40 KT
WESTERLY MEAN FLOW REGIME ACROSS NEW ENGLAND.  AGEOSTROPHIC
CIRCULATION IN ENTRANCE REGION OF UPPER JET MIGRATING ACROSS QUEBEC
MAY BE ENHANCING ACTIVITY...WHICH IS EXPECTED TO INTENSIFY FURTHER
AS IT PROPAGATES OFF THE HIGHER TERRAIN TOWARD COASTAL AREAS OF
MAINE AND SOUTHEAST NEW HAMPSHIRE. 

MOIST AIR MASS ALONG THE COASTAL PLAIN HAS HEATED TO NEAR 90F...AND
WILL SUPPORT VIGOROUS UPDRAFTS ALONG OUTFLOW BOUNDARY/GUST FRONT
ASSOCIATED WITH DEVELOPING CONVECTIVE SYSTEM...WHICH SHOULD
STRENGTHEN NEXT FEW HOURS AND SURGE TOWARD THE COAST.  THIS WILL
ENHANCE THREAT FOR DAMAGING WIND GUSTS...IN ADDITION TO LARGE
HAIL...AS ACTIVITY SWEEPS THROUGH AUGUSTA/PORTLAND AREAS OF MAINE
BETWEEN 21/23Z.
