Kathleen,
I like the Sunset Climate Zones for advice about my specific zone.
And "Weather Underground" for really detailed weather from specific weather stations.

I searched (in the search bar at the top of the page) for "Westfield NY", and got a choice of around 12 stations. Would one of these be closer to you?
Weather Station - Meadville (KGKJ) - Elevation - 1398 ft
East Lakewood Weather, Lakewood - Elevation - 1325 ft
Jamestown (KJHW) - Elevation - 1722 ft (airport??)
I keep a link to "Weather Underground" in my signature block, as "W.U."
