High probability for excessive snowfall rates later this evening. Up to 2" per hour kind of rates around midnight for parts of Connecticut. Not a big storm but most of what we get will fall in a short window.

The low level jet has shifted east and with it the damaging wind threat is quite a bit lower here in CT. Some scattered power outages but overall it doesn't look like too big of a deal.

Obsessively checking model data before a ski trip is exhausting. At least @professorpowder.bsky.social has made some awesome graphics for it.

Quite the low level jet overhead Wednesday PM. Strength of the low level inversion still a bit of a question but 50 knot gusts certainly seem possible for much of CT.

Love this shot from Hartford of some really shallow fog right over the river. Could be some black ice in a few towns tonight with temperatures near 32F.

Close call in the NW Hills on Thursday for snow vs rain. The GFS is the coldest model and is borderline at best (925hPa temps ~0c) but it is close to some heavy, wet accumulation above 1,000ft. That said, other models like the NAM and Euro are much warmer and almost all rain.

A heavy, wet snowstorm on Thanksgiving is looking more likely for southern VT and maybe parts of the Berkshires too. Great news for Mount Snow and Stratton! ⛷️

A beautiful picture of this morning’s snow from R. F. Wilton along the Bantam River in Litchfield County. A slushy inch or two fell overnight in parts of western Connecticut!

Nice looking bright band over Long Island and only about 1kft up. Change to snow will happen quickly in parts of Fairfield County.

Big signal on the ECWMF for a significant snow event in NE PA on Thursday. EFI >0.9 and a SOT of nearly 5. Could be a pretty narrow band of significant accumulation.

Really interesting setup on Friday. Cold advection from the south(!) and wrap around moisture will lead to a period of snow in parts of the state. Higher elevations in western CT favored.

GEFS showing good odds (25th to 75th percentile) of 0.75"-1.50" of precipitation for this week's storm. Typically this wouldn't be particularly excited but since September 1st we've only seen 1.30" of rain in the Hartford area!

Incredible storm developing off the Pacific Northwest. WPC has the cyclone going sub-950 hPa. Highly anomalous even for a part of the world used to intense storms.
