All sorts of low-temperature records were broken on Thanksgiving with temperatures in the teens and single digits and this cold continues into Black Friday.
So why so cold? The usual answer is also the answer today: the jet stream. This is an area of strong winds high in the sky that acts as a track for storms and also helps to separate cold air to the north and mild air to the south.
When the jet stream takes a dip, like it is over the northeast, then cold air is allowed to drop in. An area of low pressure to our northeast is helping to draw in even more cold air to New England.
This air is coming straight from Canada right into New England, bringing temperatures almost 30 degrees below average.
The cold continues into Black Friday, but we expect temperatures to moderate this weekend into the 40s and even near 50.
