A cold weather pattern will persist across much of the East after passes through the region to start this week.

The weather pattern could also feature some additional rounds of snow over the next seven days or so from the Upper Midwest to the Great Lakes and Northeast.

Cold Pattern Persists

Tuesday's Forecast

(Below-average temperatures will engulf the East by Tuesday.)

Below-average temperatures are likely for much of the East, especially as we head for the beginning of February. However, at this time, this cold blast does not appear to be as widespread and strong as the .

According to storm specialist Dr. Greg Postel of The Weather Channel:

"Some of the larger pattern drivers do support a trend toward colder temperatures in the eastern half of the U.S. as we head toward early February. How long the below-average temperatures lasts remains to be seen. The magnitude of the anomalous regime over North America could certainly lead to temperatures (at least) 10 to 15 degrees below average for several days. And the likelihood of fresh snowcover in the Upper Midwest and Northeast will probably make this cold pattern a little more fierce than it would otherwise be."

We are confident that below-average temperatures will take over the Northeast and much of the Southeast as we head through Tuesday of this week. Some locations in the Northeast could see temperatures up to 20 degrees below average on Tuesday as Winter Storm Juno moves through.

Beyond this initial cold blast, more surges of chilly air are likely to sweep across the East late this week and over the weekend. These cold air surges could be accompanied by more snow as well in the Upper Midwest, Great Lakes and Northeast. It should be noted that , for late-January standards, will be in place across the northern Plains and Upper Midwest to start this week before the cold arrives.

Temperature Outlook from NOAA

(This temperature probability forecast issued on Jan. 25 by the Climate Prediction Center is valid for Jan. 31 to Feb. 4.)

Looking even farther out in time, indications are that the cold air will hang around for the start of Feburary.

This is shown in the latest temperature probability forecast issued by the Climate Prediction Center branch of NOAA that is valid for the period between Jan. 31 and Feb. 4. The darker shades of blue show locations that have the greatest probability of seeing below-average temperatures to end January and start February.

The reason for the cold weather pattern is a broad dip in the jet stream that will stay in place from the Upper Midwest into the Northeast. This will keep cold air from Canada locked in over these regions.

Meanwhile, the West will see the opposite with the jet stream bulging northward allowing for above-average temperatures.
