The clocks have changed and just like that the chill is on this week, according to AccuWeather forecasts.

In the coming week, a dip in the jet stream will allow for even more cold air to pour into parts of the northern Plains and the Midwest. And this could persist through the first half of November.

A train of weak storm systems moving across the northern tier of the U.S. will keep delivering cold shots, that have been confined to the Plains thus far, all the way to the East Coast.

“A couple of disturbances tracking farther south around the end of the first week of November can bring the potential for some snowflakes all the way to the mid-Atlantic coast,” AccuWeather Meteorologist Dan Pydynowski said.

Temperatures across the northeastern U.S. will generally be 5-10 degrees below normal for the first few weeks of November.

Multiple widespread freezes will occur across the Northeast and mid-Atlantic.

Heavy jackets, hats, gloves and other apparel people use to stay warm will get plenty of use across the East during the first couple of weeks of November.

“The cold in much of the East is expected to ease toward the end of November. However, it looks to remain more persistent through the month in the Plains,” Pastelok said.
