No change to the forecast. Looks like half an inch to an inch of snow will be possible. Snow mixes with and changes to rain after 2am. Could be a brief period of freezing rain through 4am. The changeover time will determine delay potential, but still doesnt look all that promising.

It's time to nowcast though. We have snow entering central NY now, and will likely be reaching Cheshire County after 9pm. Currently 34 in Keene with a dew point of 18. Temperatures will fall to around 30 through midnight, before starting to rise as warm air advection moves in, and boundary layer temps rise.
