For the coast that is..inland does well, which is climo for early December

GEFS did well a month ago when the MJO was still in 6. But EPS is now catching up in forecast performance since we went into 7. And don’t sleep on the AIFS ensembles for mid-latitude 500mb at 6-15 days out. It’s been wiping the floor lately.

Congrats on winter storm Chan

That's correct... presuming temps at 5-6A are 31. Am not absolutely sure they will. be that cold in the cities. EC AI slightly warmer. No matter, intensity at onset matters. Also, by the time this gets here, I would think DPW's have treated cities to make it easier for the urban centers of I95. Otherwise some troubles lurk for the interior, including wet snow acc of 4" or more causing a few tree limbs to break s CT to NNJ

Looks like we will be in phase 8 all December. Paul Roundy thinks we will be cold through January .

Heads up, the snow burst down here in Baltimore was decent. Some folks west of I-95might get a quick dusting or coating out of thus before it flips.

Light snow..dusting in Dillsburg..Looks like we are kicking off a great stretch of winter weather! Cold, snowy December..it's about time!

What a way to end the 2025 Hurricane Season.

Flakes a flying in Exton! I have a family funeral Tuesday so yeah I am planning on a 3-6" event which will be fun to walk through the cemetery in nice shoes.

With temps along 95 being below 32F before sunrise and maybe 1" of snow falling, there could be accumulation on roads which impacts the morning rush hour before temps go above 32F and precip changes to rain and the indirect sun aids in melting.

Yep the gefs has been awful

Yeah we just had wildfires up here the past few weeks as it's gotten too dry. Getting into a drought this time of year isn't ideal but luckily the weather doesn't may any attention to our wants lol.

Temp down to 33

I thought the Euro looked pretty good. Yeah some cold rain now but the pattern is ripe to go colder with snow as we get further into December.

NWS isnt as enthused as we are. Not surprised its a tricky set up and very progressive.

Normally I would agree, but we are in a drought around me. We seriously need some rain.

Certainly could. I expect SN to start here…maybe some light accums. 3k is all snow for Gene.

First car and roof topper!

Amazing

Final burst, almost over, gave a covering on the roofs and mulch. Can't help but feel good about this winter in light of what modeling, short, medium, and long range are showing.
