Had a brief dusting with the first round of snow showers about 45 minutes ago. Enough to log a "trace" for the day but not measurable. But it did lower the temp from 40F to 31F very quickly. Sun is back out now but perhaps a more legitimate squall appears to be approaching from the west.

5.0" was the event total here. All snow from 10am to 5pm with 3.3" of accumulation, then about four hours of sleet (0.5" accumulation) with a brief period of freezing rain before going back to snow after 9pm. Picked up an additional 1.2" of snow after the late changeover.

32/30 -SN 4.8" total accumulation

32/30 -SN 4.0" total accumulation

Rapidly changing back to snow now. Probably 80% snow and 20% sleet. Total accumulation still at 3.8" on the day but we should add a little to that now.

Still pinging here in North Salem as well. We did have a brief period where it was probably 80% fzra and 20% sleet but that didn't last long. It was just enough to produce a light crusty layer on top of the earlier snow/sleet accumulation. It seems the fzra is done but we're definitely sleet at the moment. Although it isn't quite the event I had hoped for, it's still nice to have something in the month of December which has been eluding this area for the last few years.

32/30 -FZRAPL 3.8" total accumulation with a light glaze on top now

30/28 PL 3.5" total accumulation

30/28 -SNPL 3.3" total so far.

30/28 -SNPL 3.0" total so far. Looks like some solid echoes are about to move in, but I feel like we're going to be dancing with the mix line for the next several hours now.

Yep, the NAM seems to have a better handle on the mid-level warm layer compared to the HRRR. Having said that, it looks like the northward progress of the mix line MAY have halted or even been knocked back a bit over Essex County MA...but could be just a temporary trend. Hard to say at this point if we have a snowy or an icy evening coming up.

30/28 -SN 2.8" total so far in Salem NH. Watching that mix line creeping toward us.

30/28 -SN 2.0" total so far.

30/28 -SN. Total accumulation of 1.7" so far.

30/27 -SN continues. Total accumulation 1.1" in North Salem NH. Sadly, this is now the most significant December snowfall since I moved to this location in 2022. Really underscores how these last few seasons have really struggled to get started, even in southern NH. This is a nice change.

29/27 with steady -SN in Salem NH. 0.7" accumulation so far.

Overcast and 27/22 after a low of 19 here. We had a brief flurry around 7am but the real stuff is probably a couple hours away. My location will be uncomfortably close to the mixing line by late this afternoon but most guidance seems to keep it just a hair to my south. I'm just off exit 3 on I-93.

Exactly 1.5" in Salem NH. It's letting up as the heavier echoes shift north, so we're probably done now. Still, it's our first measurable since 2/27 and our first 1"+ since 2/16. We are now tied with last year's seasonal total at a whopping 36 inches.

Very interesting and valuable insight, thank you both!! The upslope signal does appear to be fairly decent from Thursday evening through Friday morning, from my perspective, so hopefully the signal holds/increases as we get closer to the event. It's been a heck of a winter for the Green Mountains, so hopefully Wednesday's rain is just a small blip on the radar before the good times resume. Think snow!!!

Question for the local experts here on "blocked" versus "unblocked" flow. This has some relevancy for a ski day I have planned for this upcoming Friday. I know that blocked flow tends to favor locations that are west of the Green Mountain spine, whereas unblocked flow favors locations to the east. It looks like most ski areas in Vermont are along/east of the spine...but I'm curious about Smuggler's Notch. In looking at topo maps, it appears that Smuggs is west of the spine. Do they tend to do better in blocked flow situations compared to other VT ski areas? I'm asking because I have a ski day with a good friend that has been on the books for this coming Friday since the autumn. Naturally, we have rain coming this week...but there may be a limited window for upslope snowfall after the departure of this ugly weather system Thursday night, and I'm trying to figure out the location that is most likely to pick up a couple/few inches of snow to *hopefully* cover up the inevitable crusty/scratchy conditions that will follow the rain. Thanks in advance!

One inch in the last hour. Storm total of 6.8 inches. Still snowing, so this will likely end up the top event of the season to date (previous was 6.9" last Saturday night/Sunday AM). It's the winter of light to moderate snow events around here.

Started pouring sleet here around 8:30, flipped to heavy snow with huge aggregates about 20 minutes later then has alternated between heavy sleet and heavy snow ever since. The temp had crashed down to 23F but is now back up to 25F. Very interesting conclusion to this event. Going out to measure around 10pm.

Took a little bit longer than I expected, but the coastal front slipped through Salem as I was clearing the slush off the driveway. It was 34F when I started, and 29F when I came inside. Freezing rain now.

We stayed snow/sleet until around 1pm here before finally flipping to rain/sleet. My final snow/sleet accumulation will be logged at 5.8 inches. The temp has crept up to 34F but it looks like the CF is going to be slipping back through here within the next few minutes. Flash freeze incoming...

About a quarter inch of sleet on top of the 5" of snow now. It's been mostly sleet here for the last two hours, but there have been very brief periods where it has gone back to snow...but usually only lasting a minute or two. Still no freezing rain at this location yet. Temp holding at 24F.
