The North Atlantic active pattern is going nuts! Countless deep low blasts across the ocean over the next 10 days. Thanks to the High over Greenland, an open corridor has been established for cold-air outbreaks moving in from Arctic Canada into the Atlantic, triggering intense storms.

An Arctic cold air mass is now spreading south across western Europe and gradually intensifying. A much colder-than-normal air mass will reach the western Mediterranean and NW Africa by Friday as well. Video via WXCharts - a MetDesk Company

Jul 12: Plumes of Saharan dust are moving across the Atlantic. This is typical in July, bringing hazy skies. This NASA model shows a forecast for the dust plumes over the next 10 days across the tropical Atlantic and Caribbean, and into the Gulf. More at

Arctic air will sweep across much of the US bringing freezing rain & snow There is some uncertainty but snow is possible in cities like Washington and New York In turn, the North Atlantic jet stream strengthens, increasing the chance of deeper low pressure systems into the UK

What’s driving the upcoming record breaking cold snap?? It’s widespread warmth (up-to 30F above normal) and intense blocking in the Arctic/ Greenland/N Canada. That is squeezing out the (tropospheric) Cold Polar Vortex and forcing it south deep into the US. While it may be tempting to blame Global warming-low Arctic sea ice-& Arctic amplification for this, the climate change component is likely enhancing, but is not the primary driver. Teleconnections to various natural oscillations (and the stratosphere) working in tandem are often the culprit in these high latitude blocks. Climate change simply piggy backs and makes the blocking - and amp’d pattern - more extreme. (But it does NOT make the cold air, colder which is a common misconception)

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: 🤓

Not a fan of the cold? Well temperatures are on the up with some milder Atlantic air moving in from Tuesday and temperatures will push back into the mid-teens for some 🌡️

A change in wind direction will bring a chillier feel over the coming days As high pressure builds over Scandinavia, we'll tap into cold air across Europe However, a slight southwards shift means the air won't be as cold as previous easterly winds the UK has seen in winter

🔵 There's no question that the North Atlantic cold blob, linked to AMOC, has become more persistent in recent decades 🔵 The current cold blob has remained for about a year, coinciding with a negative AMO, which is associated with less northward heat transport in the Atlantic.

An unusual cold patch of water in the North Atlantic could signal changes in a key ocean current, which would have sweeping consequences for climate. This blob is occurring in one of the few areas where the ocean hasn’t warmed in recent decades.

High pressure remains in charge for the next coupe of days Things become more mobile into the weekend, as low pressure skirts across the north of Scotland, pushing a cold front southwards High pressure returns to the south on Monday, bringing more settled conditions once again

After an exceptionally mild week across many areas, we are going to get a taste of winter as cold Arctic air plunges down from the north So it's probably time to get the big coat out 🥶

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.

As we enter July, models anticipate the Atlantic to remain generally quiet hurricane-wise. El Niño is dominating the current and forecast conditions in the tropical Atlantic, manifesting as high shear in the Caribbean and less thunderstorm activity than normal. By contrast, the eastern Pacific is expected to spring to life, supported by the El Niño background state. Watch the continuous cyclone activity (orange blobs) in this 35-day GEFS forecast, versus the rather docile Atlantic. We can't guarantee no Atlantic storms in July, especially with the always-present risk of so-called "home grown" development along old cold fronts that drape across the SW Atlantic and Gulf region. But things seem likely to stay in check for a while.

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:

Powering our very unusual pattern - with early season Gulf cold fronts and strong wind shear - is an extremely amplified jet stream for September. It has thrown the whole Northern Hemisphere weather off-kilter. That means cool-dry weather this weekend for North-Central Florida about a month early! It also means hurricane killing wind shear across the Atlantic Basin! Here's the science: Warm air is being forced all the way up to the Arctic circle by an elongated jet stream. That will cause an "Omega block" to form this weekend over Central Canada - you can see the Greek Omega shape with cold air on either side. These "blocking" patterns are very tough to dislodge. Because what goes up, must come down, cool air is being forced south along the Eastern Sea Board bringing Faux Fall to Florida. Faux or not, we will take it! WFLA NEWS

A strong Pacific Jet will blast mild air across the nation over the next week. Temps will once again jump to 30°+F above normal - a “blowtorch” pattern through next weekend. But we are in a very changeable/ transient pattern, with both a strong Pacific jet and also strong high-latitude blocking. The combo of these two players means, strong shifts - a week to week see-saw pattern. Not just changeable, but volatile, herky-jerky weather whiplash. In about 8-10 days cold should return to the Eastern US. The real question is: can it lock in? Or will the pattern stay transient? Probably transient given the active Pacific jet, but we’ll see.

Smack bang in the middle of the North Atlantic Ocean, 400 off the West coast of Africa, a simple draw with Uruguay has turned Cape Verde into a rave deep into early Monday morning. Only *this* game in *this* tournament. 🎥 out soon for Ep2 of The World’s Cup. Only on @COPA90.

SNOW-EFFECT SNOW?!? ❄️ As Arctic air surged south across deep snow cover in the Central U.S., it was able to pick up moisture, similar in concept (but weaker) to classic lake-effect processes. Once that cold airmass moved over snow-free, relatively warmer ground, low-level instability increased. That promoted rising motion and cloud formation, much like when Arctic air pours off the continent and out over the ocean. 🌨️ The end result: scattered snow showers and flurries showing up on radar across parts of MS, AL, TN, and KY.
