Alex, I've always wanted to criticize you with my expert conclusion

that it's kind of strange that in your area the sun cuts off the snow at this time, because now you have barely more than 11 degrees above the horizon at noon, and in our country at 22 degrees in mid-January, the sun doesn't really burn out patterns even in a dirty in the snow.But now I touched the door at work, and I have it right here exactly to the south, and we are now clear, in the morning it was 0, the water in the puddles was covered with cool needles, and now everything has melted, but the bottom line is that the door is hot, you can't hold your hand! Flies fatten, bask in the sun in droves) Maybe the sun was getting warmer, but they didn't tell us? )))
Although probably actually just because the VM is still in the AD, but quite warm, and very quiet, and all the precipitation is already under 22 degrees at noon, and the positive balance of warming up after 20.

In general, alas, we should prepare for 2-3 days of permafrost on the weekend, and you should prepare for -30 in a couple of days

We have a messenger of spring are flies in the thaw and mother-and-stepmother near housing / heating lines.
There are many signs. This is a different color of the sky and a bright, rather than dim sun and "fringe" on the snow, which you touch and it crumbles.
You're absolutely right about the angle of the sun. We have the worst frosts possible in late November-December-early January, up to -50. The most dangerous are the days with fog, when the sun is not able to melt the frosty haze, then the minimum temperature is reached, I personally saw -47.
And in February I already noticed a warm black door in the KNS on clear days. During the ngsh holidays, it was clear that I specifically went to the kns to check whether the pumps were turned off or something else, at the same time I touched the door - it was not warm, but not cold either. I.e. there is some heating.
We promise up to -21. It's not much. And then there's warming again. Some snow fell.

Well, flies are not serious ) In general, you need to look at phenological events outside the city, which is where you first bloom, by the way - quite an interesting question, you have not only a mother-stepmother, but also some other early flowers should be, I don't know if you have snowdrops, they are generally relatively southern, but something should be)

About frosts-also strange, why are the worst only until the beginning of January? In theory and in practice, the coldest month of winter in the northern regions is February, usually in late January and early February there are the most severe frosts.

There is heating in any case, even if only twilight appeared - there is already some theoretical heating, and even at 5 degrees the sun warms decently, if it is quiet and the object is dark, such as a tree, but it is believed that a positive radiation balance (diurnal) occurs when the sun rises at least an hour above 20 degrees above the horizon. This means that if the sun does not rise above 20 degrees, then the local air mass cannot be warmed up above 0C even for many days. Sort of.
We have a minimum of 19 degrees on December 20, you have about 10 degrees.

A more or less noticeable warm-up somewhere from January 20 is felt, but to sunbathe (in the sense that the skin darkens) available from March 5. Here until March 5, at least 3 hours under the sun sit-an hour at noon and an hour in both directions-nifiga, and on March 5, an hour at noon you will sit and already have a tan)
