Winds gusting to close to 60 mph brought down trees and power lines and left thousands of utility customers without power on Sunday.
And that was after record-breaking warmth on Saturday, with a high of 64 degrees. That broke the daily record of 63 set in 1975.
But the weather service says that a cold front traveled through the Genesee Valley early Sunday sending temperatures downward.
There was a high wind warning until 11am on Sunday.
The National Weather Service recorded a peak wind gust of 63 mph just after 6am on Sunday. Batavia saw a peak gust of 68 mph early Sunday.
Early Monday morning, RG&E listed about 200 customers without power in Monroe County, down from more than 6,500 at the peak of the outages on Sunday.
RG&E and NYSEG, which are both part of the company Avangrid, say that in anticipation of the storm they did mobilize additional resources.
National Grid and NYSEG had restored power to most customers in the Rochester area by late Sunday night. RG&E expects to have all customers restored to power by 4:00 p.m. on Monday.
The strong winds also caused structural damage to the Williams Opera house in the village of Attica.
The temperature fell to 28 degrees by late Sunday afternoon.
Monday will see a chance of rain or snow showers, and otherwise cloudy skies with a high of 40.
