What happened
Low pressure over Illinois brought a mix of wintry weather to parts of the Genesee Valley, the Finger Lakes and the North Country. Across the North Country the precipitation mainly fell as snow mixed with sleet at times. Nine to twelve inches accumulated over the higher elevations. Across the Genesee Valley and the Finger Lakes, the precipitation fell mainly as freezing rain. Up to an inch of ice accumulation was measured. Hardest hit areas were eastern Monroe, Wayne and northern Cayuga counties. A Federal Disaster Declaration included Livingston, Monroe, northern Cayuga, Ontario, Orleans, Oswego, and Wayne counties. The heavy ice accumulation downed trees, limbs and power and telephone lines. Over 175000 customers lost power. In some cases power outages lasted for up to one week. Schools and businesses closed for several days. Over 100 shelters were opened to house people without utilities. The falling trees and power poles produced a significant amount of damage to structures and automobiles. In Cato, northern Cayuga county, a sixty-year-old woman was killed when an ice-laden maple tree fell onto and crushed the pickup truck she was sitting in. Agriculturally, fruit trees...

Lyons, Wayne County
$5.5M damage
What happened
Severe thunderstorms moved onshore over northeast Niagara county shortly before midnight near Olcott and Golden Hill State Park in Barker. The line of storms quickly moved across Orleans, Monroe, Wayne, Ontario, and northern Cayuga counties. Across the area the damage path was nearly one hundred miles long and five to ten miles wide. Winds were estimated between 80 and 100 mph throughout the two hour event. Along the entire path, damage and debris all laid in an easterly direction consistent with the damage from straight-line winds. Most of the damage consisted of downed trees and limbs. The falling trees and limbs in turn downed power and telephone lines and resulted in damage to buildings and automobiles. Power outages, some lasting nearly a week, were widespread across parts of Orleans, Monroe and Wayne counties. Hundreds of thousands of customers were without power. The strong winds themselves also resulted in structural damage to homes, barns and buildings along the path including some in Lydonville, Albion, Holley, Brockport, Bushnells Basin, Macedon and Clyde. Several aircraft were damaged at the Rochester Airport where wind gusts were measured at 89 mph. States of...

Palmyra, Wayne County
$3.5M damage
What happened
Western and central New Yorkers experienced a rare widespread large and damaging hail event on the 16th of June. A warm humid airmass at the surface combined with an increasingly cold airmass advecting in aloft. Thunderstorm activity initially focused on the main lake convergence boundary between the Lake Erie and Lake Ontario breezes. The first cells exploded over Niagara and Orleans counties shortly before 1 p.m. and reports of hail came in almost immediately. For the next two hours, cell after cell rolled along a similar path across southern Niagara, southern Orleans, Monroe, Wayne and northern Cayuga counties���many of which had hail of up to an inch-an-a-half diameter. The activity waned for next few hours but after some additional heating due to clearing skies, more hail-filled cells developed. These storms produced hail up to two inches in diameter���a rare event for western New York. One particular thunderstorm formed over Grand Island, Erie county, and intensified as it moved southeast across the densely-populated northern and eastern suburbs of Buffalo. The golf-ball sized hail damaged thousands of automobiles as well as windows, roofs and awnings on homes. At the...
