Very cold start of winter anticipated in parts of Europe

A large area of high pressure covering the whole of eastern Europe is bringing severely low temperatures across Siberia. In a part of the world where temperatures are often below freezing at this time of year, the mercury has been 20C to 25C below average in areas over the weekend, with central and eastern Russia experiencing temperatures widely of -25C to -45C.

Over the next couple of days, westerly winds will result in temperatures rising above average in northern Russia but temperatures will remain 10C to 20C below normal in southern Russia. The orientation of the high-pressure system will allow northerly winds to send the cold air southwards across central and eastern Asia over the next few days. Temperatures will fall widely below average here too, with northern and eastern parts of China and Mongolia particularly affected. Temperatures here will fall 10C to 20C below normal by midweek as the same area of high pressure builds in and traps the cold air with temperatures struggling to rise above freezing by day.

Incredibly, by Wednesday, the huge area of high pressure affecting Russia and China will stretch all the way into the UK with an easterly wind sweeping cold air westwards across Europe. Away from Russia, there will also be a lot of cloud within this easterly flow across much of Europe. While demand for energy will increase because of the low temperatures, the low amounts of sunshine, below average wind and reduced precipitation mean that energy produced by renewable sources will be well below normal.

Meanwhile, across the Atlantic Ocean, central and western parts of the US another cold plunge is expected at the start of this week as cold air dives south from Canada once again as an area of low pressure tracks north-east. However, warm, moist air will be drawn up from the Gulf of Mexico on the eastern flank of the low pressure, bringing a risk of severe thunderstorms and potentially tornadoes to several southern states on Tuesday, especially Louisiana, Arkansas and Mississippi. As the low pressure continues to track north-east through the week, colder air will eventually affect eastern parts of the US as well.

temperatures between 4 december and 9 december compared to average in northern hemisphere



Potentially very cold in Eastern Europe later on (actually already at night due to snow accumulation and albedo effect during calm and clear nights).

Couldn't you just have carried on your previous climate thread with this?

For 18 december predictions (which is far ahead).

S**t. This will help Putin win the war in Ukraine.

[Epaminondas]

Can confirm, am briefly in Belarus and we've had heavy snow at night for over a week now.
Over a foot outside the cities.

[Antonio the Sixth]

I am definitely feeling it.

[CumbrianLefty]

S**t. This will help Putin win the war in Ukraine.

Not really, especially given how many of his ill-equipped troops could freeze to death as a result.

Why are you in Belarus?

[LAKISYLVANIA]

December currently on track to be way below average in terms of temperatures for Belgium and large parts of central, northeastern and northern Europe.

I am definitely feeling it.

Definitely coldest start of winter since 2010. December likely to be the coldest since 2010, and expected to be 2nd coldest december now acc to predictions in the 21st century.

It was cold last week (like Epaminondas said), indeed Belarus and western Russia had a very cold period back than with a large snow dump esp. on the Belarus-Russian border and also near Smolensk and Moscow, it is slightly milder now.

It was milder in Ukraine too and is now even quite mild in Ukraine since most of the cold is more to the north and northwest of Ukraine.



This is like a temperature chart for saturday night, again south and east of Ukraine seem to be quite mild while esp. Belarus and Russia are again having severely cold nights.



Seems like after next week somewhere in the weekend milder air might enter western Europe again

Temperatures today



Compared to normal, Ukraine actually way above average

[President Punxsutawney Phil]

Crazy how Ukraine is way warmer than far southern France.

[Silent Hunter]

Wasn't minus 8 here but it has snowed.

[Frodo]

It is mildest where the war is raging most fiercely.  Good for both sides, I guess.

Ngl, "Ukraine and neighboring sections of Russia are among the warmest places in Europe" was not on my bingo card.

Southern Ukraine is on the warm Black Sea. Cities like Odessa and Kherson have a similar climate to southern countries on the Mediterranean like Turkey and Greece.

I can believe that, but doesn't it rapidly change as you move away from the coast? With cold air from the north becoming particularly strong.

Yes

It's just at this very moment, there's warm southerlies blowing over Ukraine, bringing above average temperatures for parts of Ukraine.

The “coldest week of year”, temperatures set to fall to -10°C on Monday night
