December 2025 OBS and Discussion

334,000 people across the northeast without power right now. It peaked this afternoon around 400,000. 
winds were quite impressive from this storm lots of reports of 60 mph winds across Queens and Brooklyn, with winds in between 60 to 70 mph across Nassau and Suffolk. Definitely needed a high wind warning for Long Island and probably one for Queens too. Definitely over performed, the national weather service forecast as of last night were winds only up to 45 mph gusts today.

The hi res models warned about the wind threat today, sometimes it’s a false alarm. It’s pretty messy around my neighborhood and I know others not far away got it worse. We probably gusted 55-60 here.

I don't see any evidence of fresh salt chunks but all the roads look salty too me and I'm confused how lol.

I assume they put down more salt to account for the quick temperature drop and freeze up?

Ended up with 1.3" here.  Had some heavy downpours at times.  Got a burst around 3:30pm or so with crazy heavy rain for maybe 3 minutes.

Another storm signal is around the New years.

OT, but I am impressed at how rapidly snowman19 throws a weenie tag on @MJO812.

Initial post was 31 minutes ago, followed by the weenie 26 minutes ago. All happening before 6:00 am on a Saturday  

It’s almost like you guys have each others accounts linked.

Colder start to December fits within the long term trend since 1991. NYC average temperatures have only risen +0.7° in NYC from December 1st to 16th.

But the December 17th to 31st average temperatures over the same period have increased by +4.6°. This matches the streak of 55°+ days every year since 2011 around NYC from the 17th to 25th.

So my guess is that the warmest departures we see this month will occur after the 16th.

Our annual warm up over 55° between 12-17 and 12-25 was right on schedule. This pattern has become more pronounced over the years. While the general pattern did exist prior to 2011, this is the first 15 year run with no interruption. The last time we didn’t see this warm up was back in 2009 and 2010.
