Sleet and freezing rain

This storm is nowhere near finished. There remains a significant amount of moisture to our west. After a general 5 to 8 inches of snow through early afternoon across Cheshire County, snow changed to sleet. Moderate to heavy sleet has been falling for the last two to three hours, and has actually racked up notable accumulations around an inch or more, which is very difficult for removal. Sleet will continue through the evening hours, and may mix with and change to freezing rain as strong warm air advection continues aloft.



Currently in eastern New York, very heavy precipitation is showing up on radar. This will likely begin as freezing rain, with sleet under the heaviest echoes. Significant accumulations of both sleet and ice accretion are possible, and travel will be extremely difficult especially during the next 3 hours.

Precipitation will wind down after 8pm. Cold air advection will change precipitation on the back side to light snow, and additional accumulations of 1-2 inches are possible through midnight.
