Back in early January 1973, Croton was in a deep freeze similar to the one now---click on the photo--but there are 'warmer' days ahead according to News 12. In the meantime, stay warm. Wind chill advisories still in effect and it is brutal out there: http://westchester.news12.com/weather
And check out this January 2013 photo of the ice wall on Route 129 near the Croton Dam; click on the photo below.
Always a spectacular sight.
And entertaining people for generations.
