NEW YORK (PIX11) — For the next day or two, the jet stream will keep very cold air locked up over Canada. However, super typhoon Nuri, now a massively intense Low pressure
system will move up the Aleutian Island chain into Alaska. This in turn will force down that cold air and it will overspread the United States through the rest of the
week. The Rockies, northern plains, upper Midwest and Great Lakes will be the first to feel the outbreak of polar air with highs running 20 to 30 degrees below normal.

The force of the expanding cold air will push the polar jet all the way down into the southern states and even towards the Gulf Coast. Temperatures will
run 15 to 20 degrees below normal meaning highs only in the 50’s for places like New Orleans and Mobile.

As we progress through the week, the cold will nudge eastward as well and much of the eastern seaboard will feel its affects with highs
only in the 40’s and nighttime lows in the 20’s. Even NYC could drop to near freezing for the first time this season.

Snow will accompany the cold in the northern tier of the U.S. with 6″ or more in the next 48 hours. In our area, there is the potential for a period of snow, Thursday night into Friday IF a storm develops fast enough and close enough, while the cold air is pushing in.

Long range maps show below normal temperatures locked in for at least another week to 10 days once it arrives.
