Tornadoes in Western New York
April 28, 2002

On Sunday, April 28, 2002...Severe thunderstorms moved across portions of Western New York.  The hardest hit areas where in Southern Erie, Allegany, and Livingston Counties.  A National Weather Service Survey Team visited these areas, reporting the most significant damage occurred in Allegany County finding evidence of a moderately strong tornado touchdown. This tornado ranked an F2 on the Fujita Scale with winds estimated from 113 to 157 mph.  The team reported significant damage in Southern Erie County near the Town of Concord, finding evidence of a weak tornado touchdown. This tornado ranked an F0 on the Fujita Scale with winds estimated from 70 to 75 mph.  Storm damage also occurred in Livingston County near the town of Livonia, evidence suggested strong thunderstorm downburst winds.  Reportedly, there were no injuries or deaths.

Synoptic Setting...Strong short wave trough produced considerable dynamic forcing during the best part of the afternoon across Western New York. An east-west oriented warm front stretched from southern Erie county across Wyoming and into Livingston county. To the north of the front, temperatures were in the 50s and the atmosphere was stable. Along and south of the front however, temperatures reached 70 degrees and the atmosphere was very unstable. Deep low surface pressure tracked east across the length of Lake Erie and the Southern Tier counties of New York with the triple point passing just south of Buffalo. Highest surface dew points were in the mid to upper 50s across the Southern Tier. Helicity values were in the 250 to 300 range with Lifted Index values of minus 3 to minus 9 across that same area.
