A Major Nor'Easter is on the Way


NAM forecast for 00z/8 PM tomorrow (18z/2 PM model run)
Energy moving across the southeast, ample tropical moisture, and cold air draining into New England are setting the stage for a major October Nor'Easter.  Heavy snow and high winds will create near whiteout conditions tomorrow night.  We are experience and well seasoned in snowstorms around here, but this is an obvious but critical difference; its October.  That means that the leaves are still on the trees which will lead to widespread tree and power line damage across Southern New England.  The combination of the leaves, the saturated ground from recent wet weather, high winds, and weakened trees from Irene will cause numerous power outages tomorrow night.  We can deal with snow; its going to be difficult dealing with snow with downed trees and power lines.
NWS Taunton snowfall forecast

The timing of the storm is terrible.  Tomorrow night is a big party night and many people planned to be on the roads.  If you must travel (and I would advise against travel) you must take precaution.  Bring gloves, a shovel, blankets, and food and water.  Snowfall will be coming down at nearly 1-2 inches per hour at the height of the storm.  These may last for several hours.  Thus, I am forecasting 6-10 inches of snow for the Blackstone Valley, 8-12 as you head further north and west.   Folks down in the Providence to Boston corridor can expect 3-6 inches.



A Winter Storm Warning is in effect
The whole event starts as rain.  Clouds increase from South to North throughout the day and rain begins to fall between 2-4 PM.  The changeover to snow occurs as the sun sets or whenever the precip begins to become heavy, whichever occurs first.  Conditions will deteriorate quickly once the changeover occurs.  I advise for people to be off the roads by 6 PM.  The storms clears out by mid morning Sunday.  High winds will rush in behind the storm, so if power is out crews will not get to work until Sunday evening at the earliest.

Finally, I leave you with the National Weather Service in Tauton's final words about the storm...




AS A FINAL NOTE...THE CURRENT FORECAST WOULD RESULT IN THE LARGEST

EARLIEST SEASON SNOWSTORM ON RECORD FOR PORTIONS OF THE REGION.
THIS IS SHAPING UP TO BE AN EXTREMELY ANOMALOUS EVENT FOR LATE
OCTOBER.  THE MAIN CONCERN WILL NOT BE EXACT SNOWFALL AMOUNTS...BUT
THE POTENTIAL FOR SIGNIFICANT TREE DAMAGE/POWER OUTAGES.
