What happened
The episode as NWS ALY wrote it up.
On June 29, a backdoor cold front lay east to west through the St Lawrence Valley at daybreak.A weak upper level short wave trough was moving eastward across the Great Lakes. The frontdrifted a little further south during the day, but stalled over central New England. This boundary andthe approaching upper level short wave combined to trigger thunderstorms in the humid and conditionallyunstable air mass that covered southern Vermont. Thunderstorms containing heavy rain produced flashflooding in the Athens area of Windham County.

COLD FRONT DROPS SOUTH INTO REGION TODAY/TONIGHT THEN LIFTS BACK TO THE NORTH THURSDAY. FRONT COMBINED WITH PASSAGE OF UPPER TROUGH WILL BE FOCUS FOR SHOWERS AND THUNDERSTORMS INTO THIS EVENING. SCATTERED CONVECTION TUESDAY EVENING GRADUALLY DIMINISHED BUT LARGE BLOB OF CONVECTION IN CENTRAL NEW YORK AT MIDNIGHT LASTED MUCH OF THE NIGHT. TENDENCY HAS BEEN TO SLOWLY WEAKEN AND TURN NORTHEAST SO IT MAY JUST BRUSH CWA. OTHER SHOWERS POPPING UP TO OUR SOUTH. WILL BLEND EARLY MORNING POPS INTO 60-70 POPS FOR THE AFTERNOON. DRIER AIR WILL WORK INTO EXTREME NORTHWEST AND WILL LOWER POP THERE BY LATE PM.
