Well it's 14F with 7" of snow outside now. It's going to be quite different. Everyone was posting about models biasing cold earlier in the year, but PNA's at -2 to -3std for an extended period stick. Models don't bust that bad and they don't change to cold in the pattern late Dec/early Jan.

Jay was teporting 97" avout 3wks ago. Now over 177". I know Jay slant sticks at times, but closing in on 200" seems fake. Maybe their video is AI, lol Sent from my SM-S921U using Tapatalk

Thanks. I’m sure this brings you great joy.

I’m at 5.

Temp down to 21 this morning.

I ended up bottoming out at 17 yesterday morning and hit a high of 26. Am currently at the same low of 17 with dp 14. Looks like a warm-up and rain by the end of the week and then another cold shot. That means that snow piles and plowed mounds will saturate with the rain and then freeze into glaciers.

Lots of single digits on personal weather stations this morning along the Susquehanna and in the Harrisburg area this morning. Coldest one I saw was +2 in Holiday Park near Linglestown. Here in my backyard, though, I'm sitting at 14.

snowedin knows it just takes that one south shore tuck storm, to net that area at least 20 if not 40-50 inches in 12 hours

At least you aren't angry about it lol

Exactly what I’ve come to expect on Christmas Day for about the past 15 years..we take!

The WPO has been negative through our cold snap since late November. It was deeply negative a couple of days ago, which is one of the reasons we got this big cold snap the last couple of days. It looks like it goes + in about a week on the GFS and it's positive on Christmas. Which means warm east. It flips back negative towards the end of the run on the GFS. The aleutian ridge moves east over Alaska and could be working towards a +PNA, but it could be a headfake.

Maybe it will lead to a bigger SSW eventually this winter. That would be nice. It will take alot to beat mid Feb 2021. A week of winter storms

-28 with 9.5 inches of snow on the ground. -2 high temp. It snowed 4 inches, then snow showers for a couple days, then 8.5 on the 21st. It got up to 37 one of the days or we'd have had 12-13 inches on the ground. That would have probably produced -30s here.

Christmas on the 0z GFS

How many days was the less than 4" record?

Any idea how many days this -WPO has existed?

Absolutely agree & well said. Crazy how many of us love winter months. It’s truly a special time of year. It’s great smelling the firewood burning in the crisp cool fall. Nothing like a snow cover under a full moon. Plus it’s freaking great to have no insects!!!! Here is to hoping we all get plenty of snow soon!

Well said. Love learning in this forum. I had never heard of the chinook effect till here. Really good stuff! Thank You!

Yeah, the most amazing imo was Knoxville hitting -24. -27 at my house west of Pennington gap Va. Couple -30 readings and a -32 reported in rural Wise County near Norton as I recall. What did you record there John ?

29/18 for the day for DCA

Speaking of inflated measurements, someone else in Metuchen reported 8.7" vs. my report of 6.7". There's simply no way that's right, as it's an outlier vs. all other county reports (especially when, generally, more snow fell in southern Middlesex than northern) and it's a huge outlier vs. the nearby Edison reports (6.6" and 5.6") and my report of 6.7". Even when I measured on grass, the most I saw was about 7.4" so I can't imagine how someone got 8.7" - and Metuchen is only 1 square mile, so it's not like there is some gradient across town. ...Middlesex County...

Amazing what just a 1" coating of fresh snow can do if the skies can clear with very little to no wind. At 12:30am I'm down to 11.1 degrees and continuing to drop. I think that anyone with several inches of solid snowpack will find their temps in the single digits come dawn. I'll bet THV makes it down to zero. Last week my coldest reading was +6.6 degrees F. I think that's breakable. We'll see... Also, I melted down my snowfall, however I missed probably half of the accumulation because I didn't have my gauge outside on my board. I recorded somewhere between 0.8" and 1.0" of snowfall, but all of that only melted down to 0.01" of liquid! So, if you want to go with 80 : 1 SLR, I guess we can...lol. There's no doubt this snow was high ratio, however, I think the highest ratio I've ever officially recorded was around 30:1.

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