The Watch has been upgraded… 🚨Polar Vortex Warning🚨 in effect Nov 4th - 12th for a Sudden Startospheric Warming Event. Surface impacts are expected to be focused primarily in Europe, Canada, and the Northern United States beginning mid-November and lasting through December. The RISK for PERIODS of early season cold and snow during this time will be greatly increased. Stay tuned for updates. #winteriscoming #ssw #polarvortex #wxtwitter #wxX
The Latest Data is in... a POLAR VORTEX WARNING is now warrated. Stratospheric winds are expected to reverse. The next question is, for how long? #SSWE #PolarVortex #wxtwitter #wxX

The Rumford Police Department arrested a foreign national living in Massachusetts on Sunday after she allegedly attacked a man with an axe in a parking lot in a dispute over a motorcycle. ICE briefly took her into custody before realizing that she possessed a valid student visa. STORY: themainewire.com/2026/10/for…

It was always the women, and above all the young ones, who were the most bigoted adherents of the Party, the swallowers of slogans, the amateur spies and nosers−out of unorthodoxy. - George Orwell, 1984
At @UTSA for Pick Up the Mic, a student read a poem celebrating the assassination of Charlie Kirk with such glee, then told me I was brave to be out here without my neck covered. I told her I’d pray for her. This is the climate. We pick up the mic anyway.

There will be wars and rumors of wars very soon. There will be constant emergencies. Some will be real and some will be false. The purpose will be the same: to strip you of your rights. Your cash. Your conscience. Remember the COVID plandemic? Don't fall for it again.

The Sept. U.S. trade deficit in goods was $134.9 billion, the highest ever recorded in Sept. There were only three months in history when the deficit was higher, all under Trump in 2025. Here are the facts. Measured by the size of our trade deficits, Trump has been the worst president in history on trade. The tariffs have been a complete failure. Not only have they failed to bring manufacturing back to the U.S., but the U.S. is now more dependent than ever on foreign producers. Not only are we importing more than ever, but we are now paying Trump's tariffs on those imports. Trump says trade deficits represent a loss. Judged by his own standard, Trump is the biggest loser in the history of the presidency. Also, if the economy is booming as Republicans claim, why have our trade deficits gone way up? Why are the trade deficits under Trump so much larger than they were under Biden, when, according to Trump, we had the worst economy in U.S. history? Here are the facts. When you compare Trump's first two years to Biden's last two, GDP growth and job creation are slower, inflation is higher, and budget and trade deficits are bigger. If Trump is right that under Biden we had the worst economy in history, and the Trump economy is objectively worse on all counts, then the Trump economy is now the worst economy in history.

With a lot of talk about the upcoming Polar Vortex disruption and a potentially official SSW (Stratospheric Warming) event, most people cant see what makes this event "unprecedented" as its often called. And for a good reason, as a single map of the #polarvortex can be vague in context. I decided to visualize that context. The official criteria for an SSW event is the reversal (0 or negative value) of the stratospheric winds at the 10mb level along the 60N polar circle line. We are still on the edge if we will reach a reversal with this event, but there are forecast runs that suggest its likely. Link to those live forecasts is in the comments 👇 Most of the SSW events occur in January and February. I decided to look at every first SSW of each season (some seasons had two) and when it occurred. As you can see, a reversal in the current event would break the record for the earliest SSW on date by at least 3 weeks! This is really a strong outlier, and having an SSW this early in the season is what makes this event unprecedented in itself, perhaps more so than any temperature or pressure anomaly in the stratosphere. Its likely not a coincidence we get this with a very strong Super El Niño ongoing in the Pacific. So overall, this is truly a very interesting season for anyone that is into monitoring the weather and seasonal development.

Today's Long Range CFS model is advertising an abrupt end to the above normal temperatures in the Eastern US, topped off with a White Thanksgiving! Once models start to observe the predicted Polar Vortex Weakening happen, you'll probably start to see some wild solutions in November. Stay Tuned. #winteriscoming #wxtwitter #wxX

Unprecedented behavior from the #PolarVortex deserves an unprecedented blog. Usually I try to argue what's the the correct forecast, here I try to convince you that whichever forecast you believe to be correct, don't. Hopefully thought provoking! Blog live published.aer.com/aoblog/aob…

It’s important to think outside the (El Nino) box this winter. Good observation Justin
