Moscow, Russia here.
Since Autumn we have had warm and humid weather. With frequent windstorms and lots of rain and temperatures above 0 C until yesterday or so. Yesterday
the temperatures dropped to around -2 C and it began to snow heavily. From yesterday till today we had at least two inches of wet snow that fell. It
clings to everything and makes the scenery very winter-ish and pretty. Though we are still a good 5 degrees Celsius above the average temperature for
January. So it has been a very (abnormal) warm winter so far. Before the snowfall, we almost had bare earth and green grass sticking out.
Now the Norwegian MetOffice shows Moscow to have up to -23 C and my hometown, which is close by to have -26 C on the 17th of January. But since it is
a long-term model those values change every day. And it seems they are changing to the milder side. So we'll have a short cold snap, and then again a
long, mild period. And as all warm and humid periods above our glorious city, this one is caused by active low pressure systems. They make the winds
come from the west and south, bringing warm, humid air from Europe. For Moscow to have cold weather, we need the Siberian High Pressure Area to extend
Westwards and push any low pressure systems to the sides, weakening them.
And as far as I can remember this has not happened before. At least not in ten years, our last winter was cold and snow filled. And it began around
December. So there you have it. I could put up some simple Excel graphs for the average temperatures and air pressure as seen from my home thermometer
and spring (mechanical, not season of the year) barometer as large pictures. Being a hobby meteorologist and all I take hourly measures. I am also
thinking of making a Sturmglass to see if its random crystal formation and dissipation is accurate.
