According to the paper, the Aleutian high contributed to the SSW event on December 30th, 1984.

During that AH period in 1984, we were cold a few days after it formed, had a light snow event, highs in the 20s and single digit lows. Then the rest of December except for a couple of days, was very warm. We were in the 70s a week after the single digits and back in the 70s a few days after Christmas, with plenty of 60s in between. That continued into early January and the AH finally started breaking down and it flipped cold, then it flipped exceptionally cold.

Unfortunately they are notoriously hard to discharge. On average, they persist for 33 days in winter, but can go longer. About 60 percent of the time they lead to a split or displacement of the Polar Vortex, and over 95 percent of the time an early AH saw the PV disturbed later in the season. A paper I read about them noted that there could be a connection to extreme weather after they break down. They used December '84 as an example. One formed on December 3rd, the PV was disturbed on December 30th, and the AH dissolved on January 4th 1985.

Went to 5 this morning. High today has been 33.

Currently at 7 degrees, still a little more time to go a little lower.

This is the station closest to me that same date.

This is the 2nd snow in Pennington Gap in January 84. There is a 3 inch two days before.

The official record for Pennington Gap shows 2 events, a 3 and 4 inch event two days later. No idea if it's accurate or not. Shows them on the 16th and 18th. The cold front passage was one for the books. It was 63 here one day and had fallen to 1 the next day at midnight.

That's surprising to me. We had a 3 inch, 5 inch and 8 inch event in January and some -10s on multiple days. Another 7 inch event in early February with a -8 after it.

This continues to be so much like a warmer version of Dec 1983. The roller coaster temps, the light snow events with most precip falling as rain during warm ups. 1984 was a great Jan and Feb. Hopefully that is similar as well.

High was at midnight, but my afternoon hi is 18 degrees.

Downtown LaFollette during the NW flow earlier today while I was out.

18 with light snow falling this morning. Have a dusting out there.

Down to 34 with a mix falling here.

The official BOM observed for the last 3 days available (8th, 9th, 10th) has been COD/6, COD/5, and back to COD/6, but headed towards 8 (hopefully). It's 3 days behind so it could be in 8 now.

I use freeimage.host and then get the link.

Last night when it really started accumulating quickly.

Looks like I'm gonna finish up at about 1.5 inches. Shocked by this one.

Really heavy burst underway currently. Maybe the heaviest of the evening.

I'll forgive the RAP for its failure last system. I'm about to cross the 1 inch mark. Complete surprise.

Still pouring down quarters.

It's absolutely dumping here right now. Heaviest snow since November 10th.

Solid dusting down here. May be able to squeeze out 1/2 to 3/4ths inch.

For some reason a huge hole just opened up around me on radar. I was getting steady nickels and it just collapsed down to flurries with the returns going to my east and west. Hopefully it fills soon.
