Much of New England will experience sub-zero temperatures by morning. That, along with a wind still gusting past 20 mph, creates a wind chill factor of 20 to 30 degrees below zero for many of us late Wednesday night and early Thursday morning.
The old Christmas storm continues to spin well north of New England, but its influence is felt with this wind from the northwest.
Over the next couple of days, high pressure from Ontario, adjacent to a wayward polar vortex, will settle over New England. At that point, we will see a decrease in the wind and perhaps a little bit less cold air for the New Year's weekend.
High temperatures for our Thursday will be pretty close to 10 degrees; only zero if you're headed for the ski slopes, where the temperature may remain subzero.
Wind for our Thursday is gusting past 30 mph, keeping the wind chill factor near zero or colder. As a matter fact, we may have record low high temperatures for the date. The coldest high temperature for Boston on this date is 18 in 1924. We feel it may not reach 18 for a high.
Clear and cold air allows temperatures to plummet to subzero again Friday morning.
Clouds will be on the increase Friday, when the high temperature will be back up into the teens.
U.S. & World
A weak weather system, called an Alberta clipper, will race through New England on Saturday, with some light snow possible.
There will be a new storm forming at sea, but most of the heavy precipitation should stay off shore.
The exception could be from the coast of Connecticut through Rhode Island to Cape Cod, where there may be enough snow for the plows to be called out Saturday.
Otherwise, the sky will turn fair with a high temperature once again in the single numbers north and teens south.
The final day of 2017 is cold once again, but it now appears that any weekend storm should be progressive and stay far enough away that we have dry weather for New Year's Eve.
By the stroke of midnight, much of New England will again see temperatures near zero after topping out in the teens for our Sunday.
The wind will likely be active, so it'll be about as cold as it gets around here for New Year's.
New Year's Day Monday looks mostly dry, with a good amount of sunshine and a high temperature of 5 degrees north to 15 degrees south
Temperatures have to moderate a bit next week, and we may get a better shot at some snow or a wintry mix by about Thursday.
In the meantime, we will keep an eye on the coastal storms to make sure they behave.
Stay safe.
