Temperature pattern to change to much colder for the eastern US

The overall weather pattern has been very warm across the eastern states in recent days with spells of cold weather in the western US.  In fact, temperatures on Monday climbed well up into the 70’s in many parts of the Mid-Atlantic and Northeast US…very likely the warmest day until next spring.  The passage of a cold front ushered in noticeably cooler air for today and Wednesday, but an even more significant change to the temperature pattern will take place this weekend.

After Nicole exits out to the open waters of the western Atlantic early this weekend, the wind flow aloft will change to allow for the intrusion of cold air masses into the eastern states.  These air masses have been bottled up in the western US and Canada in recent weeks, but will now be able to penetrate much farther to the south and east.  Temperatures on Saturday night are likely to drop to near freezing in the Mid-Atlantic’s I-95 corridor and then a widespread hard freeze is possible late Sunday night with temperatures likely dropping well below the freezing mark.  Looking ahead, there may be the threat of snow next week in parts of the eastern US as a couple of opportunities exist for moisture to push northward from the southern US and into the cold air mass that will become entrenched across the northeastern states.

Get ready…as discussed in the 2022-2023 Winter Outlook, winter this year may get off to a quick start.
