from March 6th

yeah, did it happen or not?

I'm not an expert, but it looks like the predicted wind reversal did occur.

In the article there's this figure: https://www.climate.gov/media/16838

The March 13th 10hPa forecast with the wind reversal and lobe is visible on measured data: https://earth.nullschool.net/#2025/03/13/2100Z/wind/isobaric...

Interesting article. We are past the usual -20 or lower six weeks where I am so feels like a typical year. If I choose a random northern place like Rankin Inlet NU it is still cold up there with a low of -33 tonight. It is a sign of the times when I think huh, climate.gov… is that a reputable source?

Yeah it'll be interesting if they privatize weather forecasting in the US. I'll be looking for European forecasts of US weather...

It's handy info, but I'm not gonna subscribe to see if I need a coat or umbrella.

Earlier quoted context omitted.

What are the odds that NOAA has been forbidden to write anything about climate since this was posted?

That's the beauty of the current chaos-driven model. No explicit marching orders required. Just let it be known that inconvenient facts/actions can be punished at any time. Self-censorship takes care of the rest.

But how do you own the libs if they just start doing what you want? How does that make any sense? No retribution, no payoffs, nothing?

Nope, the firings will continue until America is made great again.

All private/paid weather forecasts still rely on NOAA’s infrastructure, so we may not have any reliable forecasting anymore.

That has been touted around before, but what does the military do? I assume they are extremely aware of their supply chain and would not want to source weather from a commercial entity.

Will NORAD start doing clandestine weather modelling to be able to plan troop/ship movements?

They’re briefing Elon Musk on China war plans, I don’t think the current leadership will care much where they source weather data as long as it aligns with the current ideological purity purge.

There is no way private weather forecasting will be profitable enough to keep the required equipment running, at least at the quality we have had.

Very interesting article, but since it's 16 days old, seems like quite irrelevant news to hit the frontpage.

Polar vortex collapse leads to cold polar air mass moving south over the course of the next few weeks. At least where I am, this article is coinciding within a day or so of the end of "fake spring".

In fact, this might help explain the concept of fake spring in general. The final collapse of the vortex is ultimately caused by warming of the northern hemisphere as spring kicks in. This implies that the pattern of "get pretty warm, then the polar vortex collapses, then you get one more surge of winter weather, and then you get real spring" is actually typical.
