THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 483
CONTINUES.
SUMMARY...LIMITED THREAT FOR STRONG STORMS IS ANTICIPATED INTO EARLY
EVENING WITHIN WW 483, MAINLY ACROSS NH AND SOUTHERN ME.
DISCUSSION...OVERALL STRONG TO SEVERE STORM ACTIVITY HAS DIMINISHED
INTO PEAK HEATING. OUTFLOW FROM LEADING CONVECTION OUTPACED DEEPER
CONVECTIVE CORES AND HAS MITIGATED A MORE SUBSTANTIAL DAMAGING WIND
THREAT. LOCALLY STRONG GUSTS REMAIN POSSIBLE ACROSS THE REMAINDER OF
DOWNEAST ME THAT HAS YET TO OVERTURN. THE UPSTREAM ROUND OF
CONVECTION FROM SOUTHERN VT TO FAR WESTERN ME HAS STRUGGLED TO
APPRECIABLY INTENSIFY DESPITE ONGOING AIRMASS RECOVERY TO ITS SOUTH
OVER MOST OF NH INTO FAR SOUTHERN ME. IT IS PLAUSIBLE THAT
CONVECTION MAY STILL INCREASE ALONG THIS OUTFLOW WITH A RISK OF
LOCALLY STRONG GUSTS. FARTHER NORTH IN ME, SURFACE TEMPERATURES IN
THE MID 60S TO LOW 70S APPEAR UNLIKELY TO SUPPORT AN INCREASED
DAMAGING WIND THREAT PRIOR TO 22Z WATCH EXPIRATION.
