Damaging Supercell Thunderstorm

A small thunderstorm developed in a rapidly destabilizing atmosphere over western Schenectady County around 4pm on Sunday June 22. The storm rapidly intensified, developing a modest mid level rotating updraft, becoming a supercell, and subsequently becoming severe between 4:20pm and 4:30pm over Schenectady and Niskayuna producing frequent vivid cloud to ground lightning, large hail, up to two inches in diameter, torrential rain, and damaging wind. The combination of the mid level rotation evident on Doppler radar and a public funnel cloud report over Guilderland at 4:22pm caused the Albany National Weather Service to upgrade a severe t-storm warning that had been issued for the storm to a tornado warning at 4:30pm valid until 5:15pm. The tornado warning included the far northern portions of Albany County, eastern Schenectady County and southern Saratoga County. A tornado warning was extended for southeast Saratoga County and issued for northern Rensselaer County at 5:12pm, valid until 6:15pm. As the storm tracked into northern Rensselaer County the mid level rotation weakened which marked the end of the severe weather. The tornado warning was cancelled shortly before 6pm as a result. Large hail (up to 1" in diameter ) and pockets of wind damage also occurred in Saratoga Springs and Wilton between 5:15pm and 5:22pm as a small locally severe t-storm split off of the main supercell and tracked to the northeast before weakening over South Glens Falls.

An Albany National Weather Service damage survey conducted on June 23 across northern Albany, Schenectady, and southern Saratoga counties concluded straight line winds ranging from 60-75 mph caused the pockets of wind damage along the path of the supercell. No tornado occurred. The damage survey also found areas where hail, up to two inches in diameter, stripped the leaves off of trees in parts of Schenectady and Niskayuna.

#1: Albany NEXRAD base reflectivity, lowest tilt, 4:55pm, June 22, 2008: Supercell t-storm over eastern Schenectady and southern Saratoga Counties. An inflow notch is clearly evident west of the Northway and just south of Clifton Park Center. The pendant area of heavy precipitation just north of Vischer Ferry at this time was the storm's hook echo as the circulation caused the precipitation to wrap around the rotating updraft. Damaging wind and large hail were occurring at this time in Clifton Park.

#2: Albany NEXRAD base reflectivity, lowest tilt, 5:04 pm Sunday June 22, 2008: Supercell over southern Saratoga County with damaging wind and large hail falling over a small portion of Clifton Park, marked generally by the magenta colored region north of the inflow notch

#3: Albany NEXRAD base reflectivity, lowest tilt, 5:27 pm Sunday June 22, 2008: Weakening supercell over northern Rensselaer County. The mid level rotation was disappearing at this time, noted by the loss of the hook echo feature that briefly became well defined over southern Saratoga County. The last of the straight line wind damage was occurring in the vicinity of Schaghticoke at this time.
