There have been a number of very memorable dis-orderly breakups here on the Mohawk and elsewhere in Upstate NY (and elsewhere). 1997 was very damaging on the Mohawk.

Higher moisture with this storm has led to some steady to heavy snowfall rates. Trends have also gone in the direction of a colder storm. 3-6" is likely across much of northern New England. A changeover to a wintry mix remains likely for southern New England. #MAwx #CTwx #RIwx #NHwx #MEwx #VTwx

There are many small scale factors that can derail long-term warm forecasts this time of year, so the extent of warmth remains to be seen. #MAwx #CTwx #RIwx #NHwx #MEwx #VTwx
