This is true. Scandinavia and Eastern Europe saw two pronounced cold snaps during the first three weeks of January.
Helsinki and SP reached -28C during each one, and they had days with highs below -20C. Further south, even places like Minsk, Warsaw, Bucharest, and Kiev saw nights in the -20s C with daytime highs below -10 at times.
If you do the math, those anomalies are the same or even greater than those of the Eastern and Central US during the best cold spells.
It was just Western Europe that was lame (as usual).
Are they though, relatively speaking? Especially if you consider the latitude difference?
On the coldest day in Helsinki this January, the 24h mean anomaly was -24.3C, x4.86 below the average mean. On that day (7 Jan) the day was 6h 10min long.
Last year on 20 Feb, NYC had an mean temp of -12C, a x7 anomaly, and the day was 10h 53min long. The same 7x anomaly was reached in January 2015. In Charleston, a 7x anomaly in February would mean a 24h mean temp of 1.5C
On the other hand, the coldest day in Helsinki in January 2015 had an 24h anomaly of x2.1 of the average.
After all, there is a huge latitude difference. So a -24C mean temp for Helsinki 60N is not as spectacular as a -12C on the latitude of Rome.
Max temps Wednesday from NAM6z. This cold is not an in & out thing. It's going to last. There is no "warmth" coming! Goodbye Ridge crap, hello Arctic.
Will be seasonable "at times" but there are reinforcing shots of Arctic air.
The first shot aims at the Southeast
The next one at the Northeast. The Flow is finally from the NW...not SW!
Almost lost my father last year due to that stupid ice storm in feb. Not to mention that they got in 2 major life threatening wrecks that month first due to error second due to stupid ice. Oh well cold and winter kill more than heat unsurprisingly. Here we go again I guess. 1958 is being used as an analog for this feb. Funny thing is Feb 1958 is an almost exact copy of Feb 2015.
How are you getting the 7x and 4.86 x? But yes, eastern North America is much colder at the same latitude in the winter than almost all of Europe at equivalent latitude.
Coldest day last year was February 16, mean temperature of 0.5°F or an anomaly of -14.6°C. Here's the distribution of winter minimums here and Paris:
I'd guess Helsinki would have a longer cold tail, with a rather skewed shape.

Daily mean divided with the normal monthly mean temp.
Also this January was the second-coldest in 30 years in Helsinki:
Daily mean divided with the normal monthly mean temp.
That measure would get skewed if a monthly mean temperature is close to 0°C, a standard deviation based measure would be better.

Looks like warm Januarys happen a bit more often, but cold January can be more anomalous than warm ones. Since 1990 looks obviously warmer than before.
Regarding on-off daily deviations (and not considering the frequency of such devoations), after checking numerous locations in non-western America and Europe, they seem pretty even to me. For example, the record low high is 22°C below average in Churchill, MB. In Helsinki it's 30°C below normal. it's 18°C and 19°C below in NYC and Bucharest, respectively.

In other news, it's been raining since I've woken up here. 82 mm (3.2") so far in Cannes, but only 27 mm (1.1") in Nice. Probably somewhere in between here. But it's so mild that it doesn't even means good snow below at least 2,000 m asl. Had it been colder, it wouldn't have rained as much though.

A simple Google search will prove that that's complete bull****. I don't know why people always say this **** without looking it up.
