Horrifically warm for New Year...

Many heat records continue to fall.
I would call this a blow-torch New Year. Widely 10-15°C above the seasonal average.
Northern Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 and my mother's bees are out.

Very unusual for January.
It needs to be above 10°C for bees to fly. Bees are almost like a thermometer.

They should be in hibernation. We got to 14°C yesterday.

One of the most northerly towns on Planet Earth (Qaanaaq, Greenland) at latitude 77.3N rose to a staggering +8.3°C today.

The sun set in late October and will not rise here until 13 February 2022. Today marks the Winter Solstice.
Really impressive warmth all over Greenland. Foehn effect in action. Warmth most profound along the west coast (to the west of high ground).
Double digits...

It is the longevity and magnitude of this warm spell that is truly exceptional. Wild temperature swings themselves are not that unusual here.

Whoaa...

Records are not just being broken, some are being smashed to pieces. 75°F in Iowa in mid December...

Unprecedented December heat with some places 40°F hotter than average. Extraordinary warmth from the Gulf of Mexico all the way into Canada.
More on the weather setup. Extreme winds widespread and unprecedented severe weather threat for December

More unprecedented severe weather is unfolding in the USA as we speak.

The warmth racing north through areas to the east of the Rockies likely to break many December records. We are talking about 30-40°F warmer than average.

The warmth is only a part of the story...

The temperature & contrast is incredible. Watch how the warm/tropical feed is blasted north and east (all the way into Canada) as low pressure ejects from the Rockies.

This is a seriously fast-moving system. A top-end wind storm is unfolding...
As the low pressure rapidly deepens, extreme wind gusts will quickly spread from the Rockies into the mid-west.

Dangerous conditions expected with 60-80 mph gusts widely, but locally 100 mph possible. Wind damage, blowing dust & fire danger are among the hazards.

Heart-wrenching news coming from the USA as extreme long-track & violent tornado leaves a path of devastation crossing *four* states.

A particularly severe setup for December fuelled by insane warmth & moisture transport under a vigorous short-wave trough.
This latest pulse of heat from the south is breaking December heat records, more to come on that.

The unfortunate combination with strong upper-level winds and high instability throughout the atmosphere meant the atmosphere was 'perfect' for extreme thunderstorms & tornadoes.
The pulse of heat from the tropics is truly remarkable. We are looking at some places east of the Rockies recording temperature values 15-20°C (20-35°F) above seasonal average.

Meanwhile, Alaska sits in the freezer.

Insane temperature contrast in Russia 🇷🇺 today.

One of the largest temperature contrasts ever recorded for a single country. A staggering difference of 85°C or 153°F.

Sub -60°C is rare and has not been observed outside Greenland plateau in the Northern Hemisphere for 10 years.
Final minimum temperature still awaiting verification in Delyankir.

Thanks for the heads up on the brutal cold @NorrathDecayMTG and very important insight from @extremetemps.

This is a profound country contrast, stay tuned for more details...
The final numbers are in.

Second largest single day spread of temperature for any country on the planet.

Storm Barra blasting across the Atlantic as we speak.

Status red wind warnings have been issued for Cork, Kerry & Clare. Damaging gusts in excess of 130km/h will be possible.

A mess of warnings across the UK with snow in the mix. Not ideal for the thousands that are still without power after Storm Arwen.
