some violence for the Cape on the 6z HRRR

Congrats Chatham and MVY. Never thought I’d say that in December lol.

Op runs go insane with the blocking in early January.

First season to date snowfall maps. This is as of December 17th, 2025. Reports are from cocorahs, COOP, and official climo sites. Contours are based on these reports and NOHRSC Gridded Snowfall Analysis. These are by far the hardest maps to put together so ill be doing them monthly similar to last season.

I'll be curious to see wind reports for my area this morning. My PWS doesn't pick up north winds well due to terrain, but it registered 39mph gusts, so I know it was higher than that. And my grill cover got blown off, and it's on quite tight.

Nothing can replace the CRAS. CRAS4LYFE

NOT hinting that this will happen, however, the setup COULD yield a storm like this. The storm tries to cut through New England however the blocking forces the storm just south.

18 this morning.

06z euro looks pretty nice for 12/23. A solid 1-3” deal for a lot of folks.

Definitely good trends overnight with a stronger NAO block. The operational models also hint at a coastal, albeit for areas south of us right now.

Longer term, the GFS & Euro both are showing the potential of a more significant coastal type of storm towards New Year’s in response to the -NAO blocking pattern that looks to become established the last week of tye month.

Nice

The overnight models are still trying to resolve the potential of a weak wave around Christmas that could deliver a mix for many of us.

Yea this is kinda where I’m at, especially with peak winter climo a few weeks away. NYC metro close enough to watch with keen interest…

The cutter will wipe anywhere that doesn’t fall below freezing tonight. Probably the usual line cutting through DAW and N ORH to just north of PWM…

Hopefully enough blocking to give BWI a 2’ storm like the 6z gfs has and cirrus for us.

This isn’t what we want for the bulk of New England. Seasonal cold and dry, especially in northern New England. Once this -NAO gets entrenched it could even result in N, to AN in Northern and eastern sections of New England. In a La Niña this is something we should be vigilante against as tendency into January is dry up here. The main takeaway is this will send most storm tracks south. I’d be watching intently in mid Atlantic, down to Virginia.

-AO - WPO - PNA - NAO is a pattern where storms moving across the midsection get sheared out and could develop into NE storms.

Christmas Day showers on the euro AI.

17 degrees this morning. No fog this morning, but I think all the road salt on the roads helped the black ice situation some.

2-5” type deal Tuesday . That’s our shot

I know it’s fantasy, but it’s nice to see the show up on the euro.. Maybe the pattern can flip back early January
