Winter to Tighten Grip on Northeast, Midwest Into Late January

Winter will tighten its grip on the Northeast and Midwest through late January as shots of colder air pour in.

A dip in the jet stream will allow chilly air from Canada to sink over the regions, reducing the chance of any prolonged warmth from New York City to Chicago through the end of the month.

"We are seeing the northern branch of the jet stream [the driver of arctic blasts] bullying the southern branch, which will prevent warmer air from getting to the Midwest and Northeast during the next 10 days," stated AccuWeather.com Long Range Expert Paul Pastelok.

"While this limits major storms from developing, it will open the door for re-enforcing cold shots," Pastelok added.

One such cold shot will pour into the northern Great Lakes and Northeast on Tuesday as the storm system that brought rain, ice and snow to the Northeast on Sunday departs.

The core of Tuesday's cold will encompass the St. Lawrence Valley, where high temperatures will average about 10 degrees below normal.

The cold will set the stage for another system to deliver a swath of snow and slick travel from the northern Plains to the Northeast through midweek.

In the wake of this system, the door will open for fresh cold to arrive later this week. However, the cold will definitely not be as harsh as what was experienced earlier this month.

Through the end of the month, Pastelok has identified Jan. 26-30 as being the coldest period for the Midwest and Northeast.

"While we have seen worse [in terms of arctic blasts], it could be a pretty cold period with temperatures averaging 6-9 degrees below normal."

As each cold shot arrives, AccuWeather.com Meteorologist Brian Lada stated that "Lake-effect snow should not be as significant as it was earlier in the winter."

"This is due to lower water temperatures when compared to earlier in the season. Ice cover is another factor that impacts lake-effect snow."

As of Sunday, 22.9 percent of the Great Lakes were covered with ice, according to the GLERL.

For those looking for a break from the cold, Pastelok anticipates a slight rebound in temperatures during the first few days of February. However, that does not mean an early start to spring.

"Another surge of arctic air is likely the second week of February," continued Pastelok.
