A significant stratospheric warming will occur in the coming... days, which will substantially weaken the polar vortex (the video shows its development over the next 14 days). 🧐 It will split into two smaller cells, one of which will gradually dissipate. Such a weak polar vortex may allow further pronounced intrusions of Arctic air into the mid-latitudes during February. 🥶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

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

Just two months after a rare stratospheric warming event... disrupted the polar vortex above Antarctica, one is poised to do the same above the Arctic before the end of November. Watch the Southern Hemisphere's vortex go from perfectly round to ragged.show more

Tropical Storm Erin will strengthen into a hurricane in... the coming hours, and in the next few days even into a major hurricane. ⚠️ The ICON model video shows its development over the next 7 days. It should remain over the ocean and curve closely around the U.S. mainland: 🧐show more

The polar vortex may have set a new record... by ending its season early. After a strong winter, it broke down in March and won't recover, one of the earliest stratospheric vortex collapses in history.show more

The Arctic flood gates are opening up, as a... strong & warm (relatively) block grows over Greenland. That warmth will shove the frigid Polar Vortex south, with multiple cold plunges in the batters box for the next 10-15 days in the Midwest, Great Lakes, Northeast and Mid-Atlantic. The chilly air will visit the Deep South and #Florida periodically too.show more

NOAA forecasts show the polar vortex may have ended... its season early. After a strong showing this winter, it was disrupted in early March and isn’t expected to recover, marking one of the earliest breakdowns of the stratospheric vortex in decades.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

2022 ended with a shiver, but the start of... 2023 broke a sweat. 🥶🥵 This weather whiplash may have been caused by changes in the polar vortex, the band of strong westerly winds over the Arctic. Details:show more

The battle of the seasons continues! The heat dome... vs the polar vortex duking it out for dominance. We all know how this ends, but the Polar Vortex still has some gas in the tank! First the #heatdome brings record heat to #Florida this week - feels like 100° - then the Polar Vortex slings another chilly shot south next week with most of the East dipping 10-15° degrees below normal. For Florida, drier, milder air will help lower the temperature a bit, but not for long and not by much. North of I-4 pleasant (but not cool) air will return by Tuesday/ Wednesday.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

Cold and mild air are going to battle it... out over the UK in the coming days. Which one will win?show more

🥶 The Cold Won’t Quit! The first few days... of May will feature another cold plunge of air in the East! Summer on hold… for now. 🥶 The chill will reach into the Northern half of #Florida, but probably not to S FL.show more

Major Hurricane #Kirk (cat 4) is now in the... Atlantic. It will continue moving towards Europe. 🧐 By mid-week, it is expected to weaken into a post-tropical storm and reach France (see wind gust map for the next 5 days).show more

After an extraordinary holiday heat dome across the US,... get ready for a Polar Vortex Invasion next week! Cold air will surge deeeeeep South with 20s in the Southeast and 30s far south into #Florida. What’s most interesting is airmass won’t be super cold up north - just slightly below normal. Instead the South will get the brunt, with the SE & FL 15-20° below normal!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

We know your pain Pathan. Panjabi nationalism will only... unify Pakistan into a single entity which will crush anyone who stands in its path. Gone are the days where Pathans, Blochis, Sindhis and Majars gave guilt trip. We had enough, one day all of you will speak Panjabi!show more
