67 BELOW ZERO IN ALASKA!

The temperature dropped to frigid 67 below zero at Chandalar Lake in NE Alaska today. This is the coldest I have noticed in Alaska or Canada so far this winter. The wind chill was 95 below!

It was 65 below at Burwash in the Yukon Territory of NW Canada. Tanna, Alaska had 57 below. In Fairbanks, visibility was only 1/4 mile in ice fog with a temperature of 47 below but a wind chill 65 below!

Chandalar Lake is in the Brooks Range of NE Alaska 60 miles north of the Arctic Circle. It can be reached only by air (bush pilots) although snow machines are used in winter. The FAA maintains an aircraft navagation beacon there. There are also some year-round resort inns on the shores of the lake.

What does this mean for us in the Deep South? Don't know but for the time being the worst of this frigid airmass is locked up although occasional pieces of it will invade the northern Lower 48. Even tonight, blizzard conditions are expected in Eastern Montana with temperatures falling far below zero.

JB,
you told me once in an email several years ago that you look for high pressures in that region as a precursor to arctic air intrusions here. I take it with air that cold, the pressures must be very high.

Winter is indeed a long way from over.

The pressure is high but not excessively so. at least not yet. I really get concerned when the SLP rises to over 31 inches and 1060 MB or higher with it that cold.

The upper air pattern is progged to stay unfavorable for an invasion of the bitter cold into the Deep South anytime soon. (zonal flow at 500 MB) Sort of a fence against the cold.
