December 2025 through February 2026 was the 2nd warmest winter on record for the Contiguous U.S. according to Prism climate data. The widespread record to near record warmth in the west easily outweighed the cool temps in the east. πŸ”₯πŸ”₯πŸ”₯

It continues to look like a pattern change will come around the second week of March, bringing milder weather to New England. There are many small scale factors that can derail long-term warm forecasts this time of year, so the extent of warmth remains to be seen. #MAwx #CTwx #RIwx #NHwx #MEwx #VTwx

Active Pattern Set to Continue for New England New England’s pattern will remain generally unsettled over the coming week as several disturbances move through or nearby the region.

A generally active pattern will remain over New England, though not all of these systems will be particularly strong, or make a direct impact to the region. #MAwx #CTwx #RIwx #NHwx #MEwx #VTwx

Just incredible that this is moving so slowly. This is why we need S9119/A10138 or S5759c/A6192d in NY to manage biosolids and put a five year moratorium on sale or use. #PFAS

I was proud to join clean water advocates yesterday for the Hudson River Advocacy Day.

The Hudson River is a critical resource environmentally and economically and it is vital that we maintain the health of this historic waterway for the benefit of our community and future generations.

New Jersey acts on 'forever chemicals' β€” who’s next? New Jersey joins 29 other states that have started to address the threat of PFAS.

NYS has similar bill already passed in Senate. Will you @speakercarlheastie.bsky.social ignore it yet again? If EPA is rolling back #PFAS regs & allowing industry to pollute more, you NEED to do your 1st job & protect public health. You too @governor.ny.gov

Blizzard warnings have once again been expanded across New England as confidence in high wind gusts extending north & well inland has increased. Not much change to snowfall thinking. With a powerful storm and multiple snow bands, snow totals will be highly varied. #MAwx #CTwx #RIwx #NHwx #MEwx #VTwx
