cold February projected
Re: cold February projected
This is agrees with Joe Bastardi's outlook for last week of January for the month of February.
"The winter is not over and the reprieve, at least in temperatures, that North America has enjoyed during the last few weeks will return to a typical La Nina state. It's one that favors clipper systems moving through the Canadian Prairies into the north-central U.S. and bringing bouts of cold, arctic air behind them. Some of these pushes could be harsh going into February, and enough to make it down into the Southeast, but that is not guaranteed.
The polar vortex will be making a visit yet again, spreading the cold, arctic air through Canada and into the U.S., but it may take a little time yet to do so. The question now is, how long does this last?
There are a few reasons to believe this pattern will continue through February and into March. One of those is the orientation of the polar vortex higher up in the stratosphere. Models suggest a warming event late this month into early February. When those events occur, cold events tend to happen a few weeks later, which would be in late February into March. If the beginning of February favors cold across Western Canada and the north-central U.S. and the late month does as well, we could see a good portion of the middle of North America staying colder through a good chunk of February."
Joe Bastardi expects the weather pattern (dip in the jet stream) will hang around east of the Rockies well into March and may keep April cooler than normal.
