Haven't looked at 925 temps but euro prefip algo showed rain for a good chunk, here

New SREF

Looks like we are picking up on a modest event here on Monday. To me looks like we may be heading into a pattern where we will be saying over the next two weeks. "It just likes to snow here."

We’re probably about to have a healthy 12z nam

I can picture it already.......seeing me in green with "mostly rain" scrawled through it.

Like a fart ? Did you have to let it linger

12Z HRRR has a nice strip of moisture developing over WNC tonight around 9-10pm. This seems to have some legs here. Perfect timing for snow to accumulate.

Ahh ok. Us out here WOR need a few ticks west for sure. Hope that happens.

Yeah. Some models also tried lingering it into Monday too.

That's a pretty healthy band of snow basically Delaware County / Chester County line points west. Saw the Cams out of Chester and Lancaster County and it is coming down at a pretty good clip that stays there or slowly moves east that could put down a quick 1-2". I would think we are getting close to issuing a winter weather advisory for most places I-95 points west and northwest. All of this is inching eastbound and will over time.

No offense to you and others, but you all have had a few bones thrown away the last several years. The only thing I have thrown my way was Kevin’s Weedwhacker up my fanny.

12z Hrrr at 17hrs looking further west than 0z.

Not sure how much compaction occurred with the brief mix we had but definitely at least 2 inches. So I think that was an over performer. Most were calling for .5 to 1 inch over night for part 1. NAM was horrible. Canadian was best that I could tell. Nice that we had high moisture content. doesn't subliminnate as quick so want to keep this around until late next week. Not sure when the snow squalls are supposed to come today.

The 6z 3k NAM and EC are throwing a few inches at the Philly metro area.

January 17 1996: A severe ice storm hits the western and northern Twin Cities with accumulations between a half an inch and an inch. A foot of snow fell over central Minnesota. 1982: The citizens of Tower wake up to a frigid low of -52 degrees F.

Looks like this comes in tomorrow afternoon and heaviest is into the night?

The 6z was a pretty unanimous move to the west/NW.

I’d like to have several inches of man paste hopefully with the snow. I don’t want fluff. I’m done with that and now it’s almost an angle season.

It's a beautiful blue morning up here! I'm guessing that the blue appearance is due in part to the high moisture content of the snow. Sent from my Pixel 10 Pro using Tapatalk

Nothing coming easy for us the last 4-5 years that’s for sure. But we seasoned now, we hardened, and we push on…we are New Englanders.

I'll do a revised map tonight.

No, I’m not saying a total reverse, but if I see things start moving east that’s gonna be disappointing. I’d like to see a continue ticking west right up to game time. I think for me I’m going to need the rates so I’d like to see some meat in this.

One can save a lot of time in their day if they simply look to see how the post/page count has changed on a storm thread. The obs threads are always trainwrecks. lol
