Was checking out the snowfall totals on CoCoRaHS from the lake effect event on Friday... I didn't realize that some locations got over a foot in Madison and Oneida counties! I ended up with about 8 inches in the city of Syracuse

Not the fossil fuel companies that correctly predicted climate change with their own climate models in the 1980s, and then started to spread disinformation in the 90s to profit off their known destruction of the planet, right?

The US dodged a bullet this year with no direct hit by a hurricane… especially during the government shutdown. Huge props to the forecasters at the NHC who worked without pay (and the hurricane hunters!)

So cool: northerly wind at the surface bringing in lake effect snow from Lake Ontario, and southerly wind higher up in the atmosphere bringing in snow from the south. Two different types of snow ❄️

So he’s… literally trying to starve Americans
The Trump administration told states that they must “immediately undo” any actions to provide full food stamp benefits to low-income families, in a move that added to the chaos surrounding the nation’s largest anti-hunger program during the government shutdown. www.nytimes.com/2025/11/09/b...

Dems are on track to flip the Onondaga County Legislature (where Syracuse, NY is). It was 12R-5D. Dems are currently up 10D-7R. That's 5 seats flipping in a 17 seat legislature! Don't overlook the local elections people!!

Just plotted the 58 METAR stations that are expected to stop reporting observations due to the FAA ending their contracts. Overlaid the counties in NC that issued a disaster declaration after Hurricane Helene last year.

Shockingly, because of the government shutdown, the hurricane hunters are going unpaid as they risk their lives for theise data. And staff at the National Hurricane Center are also without pay as they continue to perform their critical duties during this record-breaking storm.

Since the federal government shutdown began, public servants are already feeling the effects of Congress’s failure to move forward with funding.
