First snow of the season looks to be supported by most of the guidance we use for forecasting our weather across the CONUS.  Our weather in New England this time of year gets particularly colder as we venture to the beginning of November through the end of March, this time period is notorious for heavy snowstorms, more so towards DEC through FEB sometimes including NOV and MAR.  This winter supports a La Nina pattern, although weak, but present should feature more of a negative PNA and positive NAO, but you never know how these blocks of the atmosphere will behave.  We could have our first widespread snowstorm either NOV 9-11 or NOV 14-16th of this upcoming two week period as the PV (polar vortex) enters our side of the hemisphere and tries to get involved in our air masses from Canada and the Arctic Circle.  We are entering the season for explosive nor'easters in the North Atlantic/Arctic region which lends us to believe that cold air is indeed present on our side of the hemisphere, now this upcoming week from Thursday Nov 2nd to Nov 9th will be a step down period from modestly warm weather tomorrow through the weekend to appreciably colder and perhaps an arctic chill to the air will be felt next weekend, this should set the stage for our first rain/snow storm.  Stay tuned!
