For several weeks now, a significantly colder-than-average air mass... has been present over Antarctica. 🧐🥶 In the coming days, temperatures there are expected to remain more than 20 °C / 40 °F below the long-term average (see the video). This mass of Antarctic air is concentrated mainly over the continent, where it has persisted for an extended period. In recent days, some of this cold air has also spread into South America, bringing below-average winter temperatures there as well:show more

In recent days, cold air has begun to flow... into Central and Western Europe. In the coming days, the influx of cold air into Europe will intensify further. 🧐 🥶 At the beginning of the new year, most of Europe will experience below-average temperatures, with all-day frosts in many areas. The video shows the development of the temperature anomaly in Europe over the next 12 days, up to January 6:show more

The video shows the development of the temperature anomaly... over the next 14 days in Europe. Temperatures will remain consistently below average, especially in Central and Eastern Europe. 🧐 This represents a long and significant stretch of below-average days:show more

Eastern Europe is set to experience the strongest cold... spell of this winter so far, especially in Ukraine and Belarus. 🥶🧐 Temperatures will drop below −25 °C around the turn of the week, which is 10 to 20 °C lower than is typical for the region: However, the mass of Arctic air will not spread much farther into Europe and will stall over Eastern Europe. The temperature evolution over the next five days is shown in the video below.show more

A mass of Arctic air will become trapped over... eastern Europe. 🥶 In #Ukraine, #Belarus, and western #Russia, temperatures will regularly drop to around −20 °C over the next at least 14 days, while daytime highs will be only around −10 °C (watch the temperature outlook for the next 14 days): 🧐 These are below-average temperatures which, according to current forecasts, could persist throughout the entire month of January.show more

Below-average temperatures will persist in Eastern Europe. 🧐 In... addition, a strong cold front on Sunday will push temperatures even further below normal, making them significantly below average in some places (see the temperature anomaly for the next 7 days): Snowfall will also return to the mountains, while in Russia it will snow even at lower elevations. ❄️⛷️In Western Europe, on the other hand, temperatures will be near or above average.show more

For the first time this winter, the polar vortex... is expected to break up. 🧐 Although it is currently strong, it will begin to weaken over the next seven days and split into several smaller vortices by mid-February. This process could bring below-average temperatures to Europe in the second half of February. 🤗show more

Alaska is experiencing one of the coldest winters since... 1918. 🥶 In the city of Fairbanks, temperatures regularly stayed below −19 °C (−2 °F) from December 13 to January 16 (see video) and remained consistently below average. 🧐 It was only yesterday that temperatures finally rose: This is the longest continuous period with temperatures below −19 °C recorded in the city since 1918.show more

☀️🌡️ Another heatwave is expected in Europe. Temperatures may... exceed 40 °C as the summer solstice approaches Across many parts of western, southwestern, central, and northern Europe, temperatures are expected to rise well above the long-term average in the coming days. Unusually warm weather is already affecting the southwest of the continent. In Galicia, Spain, the Coruña Airport weather station recorded a high of 37.7 °C over the weekend, marking the station's highest temperature ever. In the second half of the week, exceptional heat will spread across much of Europe, as very warm air from the south gradually moves farther north along the western side of a high-pressure system. The heatwave is likely to be most pronounced in Spain and France, where temperatures could climb above 40 °C over the weekend, with local anomalies exceeding the long-term average by up to 15 °C. It is still unclear how long the hot weather will last, but some models suggest it could continue into next week. The upcoming heatwave could bring higher peak temperatures than the late-May event, partly because it comes around the summer solstice, when days are longest. ⚠️ Keep an eye on the latest forecasts and official warnings.show more

Still very warm across southeast England this afternoon, with... temperatures around 22–23 °C, and locally 24–25 °C in parts of East Anglia and Kent For most areas though, highs are 8–10 °C lower than yesterday, with temperatures returning closer to average over the coming daysshow more

Feeling more like early spring over the next couple... of days, as a northerly airflow keeps us in a notably cool airmass This will bring below average temperatures along with brisk winds at times, all adding to the chill 🥶show more

Winter comeback in Europe? 🧐Across much of Europe, a... prolonged period of below-average temperatures will begin on Wednesday. 🥶 This is likely to last until Easter. The video shows the development of temperature anomalies from Wednesday one week ahead. At the same time, there will be plenty of precipitation, so higher elevations will see significant snowfall. ❄️ Much of Europe is heading for a cold transition from March to April and likely also a chilly Easter.show more

⚠️ I’m not liking the way this Winter Storm... is trending for our Texas brotheren.... One aspect that isn’t being talked about enough is the combination of significant Ice Accumulations followed by days of Brutal Cold. If Texas were to receive even a fraction of the ice currently being shown, widespread power outages would become a real concern. With frigid air rushing in behind the storm, temperatures could remain at or below freezing for days, making recovery much harder. This will not be as cold as the deadly Winter Storm of 2021, but the dangerous combination of ice and prolonged cold will still be there. 🌡️ Some areas could see temperatures 30 to 40 degrees below average after the storm, which would compound impacts if outages occur. I’m not saying panic, my Texas brotheren, but this is a situation worth paying attention to and preparing for if current trends hold. 👀 I’ll be watching this LIKE A HAWK 🦅show more

There is NO END IN SIGHT to this brutally... Cold pattern, with multiple waves of Arctic air likely to continue pouring into the U.S. well into mid-December. The Polar Jet Stream will keep diving south again and again, dragging down round after round of frigid Canadian air. This is the kind of cold we normally see in the heart of January - seeing it this early is highly unusual. Temperatures will run 10, 20, even 30 degrees below normal, and some locations may drop below zero for a prolonged stretch. Wind chills will be even worse. Bottom line: ⬇️ The cold isn’t going anywhere. Bundle up… it’s going to be a long, frigid stretch. 🥶show more

The ongoing record-breaking heat wave in the West will... continue while expanding across the Central U.S. through the weekend. Based on preliminary data, there have been around 50 March high temperature records broken since March 17 and more than 150 daily high temperature records broken. Record setting temperatures are expected to continue over the next several days. Most areas will see temperature departures of 25 to 35 degrees higher than normal for this time of year. However, some locations in the central Plains on Saturday could see departures exceed 40 degrees from normal! Overnight low temperatures will also be well above average, providing little relief from the heat. The early time of year, prolonged nature of this heat wave, and limited seasonal acclimation will increase the risk of heat impacts especially among sensitive populations or those without effective cooling. Adjust plans to limit strenuous outdoor activities to early morning hours, drink plenty of fluids, and seek air conditioned spaces. For more heat safety tips visit:show more

🌡️ Unusually intense May heatwave in Europe This weekend... will bring very high temperatures to southwestern, western, and partly central Europe, locally up to 15 °C above the long-term average. The reason is a persistent high-pressure system over Europe, drawing in hot air from North Africa along its western flank and acting as a so-called heat dome. Air in the center of the high sinks and warms, suppressing cloud formation and allowing more solar radiation to reach the surface. As a result, hot air accumulates near the ground and continues to intensify. Temperatures may exceed 30 °C in western and central Europe, and reach up to 38 °C in southwestern Spain. Numerous daily temperature records are expected to be broken.show more

Extreme rainfall is signalled for central and southern Europe... to end the week, with 200-300 mm possible (double the September average) Some rivers may experience 1 in 100 year events As cold air digs in, over a metre of snow could also fall over parts of the Alpsshow more

A rare critical fire danger over NW IL, and... elevated for everything else west of the Fox River across northern IL In spite of light overnite rain, an extremely dry air mass flowing in (dewpoints 30°-40° below air temps), very windy conditions with sustained winds over 20mph and gusts 40+, full sunshine, all on top of lots of field stubble that has been snow cover free for several days to weeks, will combine to create dangerously dry fuel for any “spark” that could take hold This same inbound airmass created massive wildfires over western OK and KS yesterday Video from chaser Jaden Pappenheim Jaden Pappenheimshow more

Finally, relief for Europe!😍😍 A vast cold front is... advancing from the Atlantic into Western Europe. The video below shows its development over the next 24 hours. As it moves eastward, it will gradually bring cooler air and lower temperatures back to more comfortable levels: 🤓show more
