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

This latest pulse of heat from the south is breaking December heat records, more to come on that.

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.

More on the tornado... Potentially historic in track length. 250 miles is eye-watering.

Radar suggests debris was lofted over 30,000 feet.

This is the weather pattern. Low pressure ejecting from the Rockies with extreme warm plume racing north through much of the Eastern USA.
Brief cool down on the back edge with some snow (finally) for some parts of the Rockies which have tied their longest run of snowless days.
