The episode as NWS ALY wrote it up.
A moist and unstable air mass ahead of an advancing cold front led to the developing of thunderstorms during the early afternoon hours on Tuesday, June 9th across eastern New York. As the thunderstorms organized into small lines, some of the thunderstorms produced wind damage, mainly to trees and power lines. These thunderstorms reached southern Vermont by the mid afternoon hours and produced a report of wind damage near Halifax.
Thunderstorms ended over the region by the late afternoon, as the cold front crossed the region from west to east.

THEY ARE EXTREMELY HELPFUL AND HELP US MATCH UP WHAT WE ARE SEEING ON RADAR TO CONTINUE TO WARN OTHERS IN THE PATHS OF THE STORMS. LINE OF STRONG TO SEVERE THUNDERSTORMS TRACKING THROUGH WESTERN NEW ENGLAND. KALB 18Z SOUNDING SHOWS MORE INSTABILITY...AND SOME DRY AIR ALOFT...SO CONVECTIVE PRECIPITATION CORES GETTING ENHANCED AS HEAVY PRECIPITATION FALLS. SOME SMALL HAIL IN STORMS ALSO BUT BOWING SEGMENTS PRODUCING DAMAGING WINDS SEEMS TO BE THE BIGGER THREAT. BASED ON CONDITIONS TO THE EAST...CONVECTION SHOULD MAINTAIN STRENGTH AND SEVERE WEATHER WITH SCATTERED DAMAGING WINDS EXPECTED THROUGH THE TACONICS...SOUTHERN VT...THE BERKSHIRES AND NW CT BY SUNSET. THERE IS AN AREA OF RAIN BEHIND THE THUNDERSTORMS AND MANY AREAS WILL SEE THE PATCHY LIGHT RAIN THIS EVENING...WITH DECREASING COVERAGE THROUGH THE NIGHT. THE RAIN IS EXPECTED TO LINGER A BIT IN NORTHERN AREAS. HOWEVER...ALL AREAS WILL SEE SOME GRADUAL CLEARING BETWEEN MIDNIGHT AND SUNRISE. WITH PARTIAL CLEARING OVERNIGHT LOWS WILL FALL TO THE 50S. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/... WEAK HIGH PRESSURE CONTROLS OUR WEATHER WEDNESDAY...BUT ANOTHER WEAK COLD FRONT APPROACHES LATE WEDNESDAY AFTERNOON AND NIGHT FROM THE NORTH. MOST OF THE DAY SHOULD BE SUNNY...BUT SOME ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS COULD APPROACH THE WESTERN MOHAWK VALLEY AND SOUTHERN ADIRONDACKS LATE IN THE AFTERNOON. HIGHS WEDNESDAY IN THE LOWER TO MID 80S...SOME MID TO UPPER 70S SOUTHERN ADIRONDACKS. THE WEAK COLD FRONT SLOWLY DROPS SOUTH AND SOME INTERVALS OF CLOUDS AND SCATTERED TO ISOLATED SHOWERS AND THUNDERSTORMS WILL AFFECT MUCH OF THE AREA. BOUNDARY LAYER WEST TO SOUTHWEST WINDS STRENGTHEN QUITE A BIT BUT THERE IS CONSIDERABLY LESS DEEP MOISTURE EXPECTED WITH THIS FRONT. TEMPERATURES WILL FALL INTO THE 60S TO NEAR 70...AGAIN WITH PERIODS OF CLOUDS AND SCATTERED TO ISOLATED SHOWERS AND THUNDERSTORMS. THERE ARE SOME INDICATIONS THAT THE FRONT STALLS JUST SOUTH OF OUR REGION...BUT THE BOUNDARY LAYER THERMAL GRADIENT SETS UP OVER NORTHERN PARTS OF THE REGION. NOT INCLUDING ANY ISOLATED SHOWERS OR THUNDERSTORMS BUT WILL SEE WHERE THE FRONT STALLS AS WE GET CLOSER TO THURSDAY. HIGHS THURSDAY IN THE MID TO UPPER 80S...SOME UPPER 70S TO LOWER 80S IN THE SOUTHERN ADIRONDACKS. THERE COULD BE VERY GOOD MIXING WITH RELATIVELY STRONG WEST TO SOUTHWEST BOUNDARY LAYER WINDS AND BEING ON THE WARMER SIDE OF THE BOUNDARY LAYER THERMAL GRADIENT...SO TEMPERATURES COULD EVEN BE A COUPLE OF DEGREES WARMER. ANOTHER UPPER IMPULSE AND SOME WEAK LOW LEVEL FORCING IS EXPECTED FRIDAY...WITH INCREASING WARM ADVECTION...EXPECTED TO DRAW THE OLD SURFACE FRONTAL BOUNDARY FROM SOUTH OF OUR REGION NORTH THROUGH OUR REGION.

A SERIES OF WEAK LOW PRESSURE SYSTEMS AND FRONTAL BOUNDARIES NEARBY WILL MEAN A CHANCE FOR SHOWERS AND THUNDERSTORMS FOR MUCH OF THE PERIOD...MAINLY EARLY ON...THE BEST CHANCE OF WHICH WILL BE ON SATURDAY WITH A STATIONARY FRONT DOTTED WITH WEAK LOW PRESSURE AREAS DRAPED ACROSS NEW YORK STATE. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/...
