Western New York Weather History

APRIL 5

 

1941

As a result of heavy rains in western New York, streams and rivers in many sections overflowed their banks, causing flood conditions to prevail. Many of the main roads were closed in part. In the vicinity of Lancaster the water rose 13 feet above normal. Many cellars were flooded and a number of telephone lines were out of order. Losses probably will exceed $10,000. At the city office 1.28 inches fell in less than 24 hours and 2.02 inches at the Buffalo Airport.

2003

4TH-5TH...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 were severely damaged, especially the tart cherry trees in Wayne county.

2007

5th-8th...The lake event began late Wednesday April 4th following a sharp cold front. A massive upper level low then set up over Quebec and poured near record cold across the eastern two thirds of the nation for several days. Late season lake effect snows continued through the 8th. Although Lake Erie had a good deal of ice cover, the moist northwest flow brought residual moisture from the Upper Lakes and dropped up to a foot of upslope and lake enhanced snow across parts of Chautauqua and Cattaraugus counties. For the next few days, lake snows became more organized during the late night and early morning periods—breaking up into cellular activity during the afternoon and early evening hours. The heavier accumulations were at night. The Thursday night-Friday morning period brought 6-12” to much of Oswego county and southern Tug Hill and also another 6 to 12 across Chautauqua county. The Friday night-Saturday morning period saw an intense band across southern Jefferson county with somewhat of a repeat along the south shore of the Lake Saturday night and Sunday morning. Conditions finally moderated enough to shut down any lake snows late Sunday. Some representative total amounts off Lake Erie: Perrysburg 26”; Mayville 23”; Arkwright 18”; and Jamestown 15”. Off Lake Ontario: Redfield 28”; Parish and Hooker 24”; Highmarket 18”; Fulton 16”; and Constantia 15”.
