Solid cold, -28,6°C was officially recorded in the East with temps below -30°C likely in the coming nights. Where I live it's around -21°C at the moment. I love it, went skiing yesterday.
Freezing conditions down deep the Balkans, mild Atlantic conditions in the West.
Note that these are late afternoon temps, during the night it will be much colder:
Nice map. The cold blast I saw last week was colder further down into Croatia and the Balkans. I also saw some really cold temps in Turkey and even freezing temps down to southern Turkey. I wish I could view maps like you show of past temperatures. Do they have those?
"differences varying from a few minutes, to in extreme cases, as much as an hour on a daily basis"
Yes, that was the problem with Foster machine that I read about. On days with high thin cloud, it recorded sunshine. An hour a day could be up to hundreds of hours a year, though I doubt they would have that level of difference sustained. I am pretty sure though based on my comparison of converted solar data for Philadelphia that you lose around 150-200 hours per year in this area. The solar sensor in Avondale PA west of Philadelphia averages a little over 2300 per year based on the past few years, while NOAA claimed our airport averaged 2500 hours with Foster.
And the major point is that the US is not as sunny as the old NOAA hours show. Just fact.

Sadly, historical maps from past conditions around Europe stay only for a couple of days, except of France.
You can click on a station to see past conditions, but the maps aren't there anymore.

Yea, when he says in "extreme cases, up to an hour", I would doubt that it would amount to "hundred" of hours as you said. Reasonably, 150-200 hours a year above what the WMO sensor would detect. For Chicago as well, 2600 about ours annual is what NOAA claimed with the Foster (this site says 2611). So about 2400-2450 with the Kipp Zonnen seems realistic.

Can you give me the link to click on a station? Thanks.

Is the only way to discern if any stations in my area to sort through hundreds of COOP stations one by one!?
Impressive cold in Scandinavia / Northern Europe, even Northern Holland is below freezing
