Light snow down in Barnstable (Cape Cod)

Dangerous to lump in ACK with Cape Cod when it comes to winter weather. Proceed at your own peril!

I think we are splitting hairs, but to say 30 minutes of mixing (which I never observed in the mid-cape) met the criteria that was clearly being predicted is a stretch. Given it was a long duration 36 hour storm, 30 minutes of mixing vs. the predicated 50% storm duration is the opposite of "nailing" the forecast. If memory serves right ratios were also solid, and no where near the 8:1 or 10:1 one would expect if temps were as high as you believe they were. Also I would consider the Cape a different region all together when compared to MV and ACK. That's why they call it Cape Cod & the Islands . I don't think those locations are relevant to the conversation given they are very much their own climates due the ocean, but if those spots did receive 24", there's no way the Cape received less given a gradient to 36 in the Plymouth area. HRRR really cutting back QPF amounts this afternoon though, looks like SNE will be a pretty tough call.

Never intended to indicate that Boston was every predicted to changeover to rain. Was speaking specifically about the cape where nearly every met predicted 8-16 inches due to a firm changeover to rain. We ended up with 30-36 inches. Not sure whether a few minutes of mixing would qualify as confirmation given the wildly incorrect amounts. Matt Noyes did the best if memory serves right. But anyways, off topic, back to this nice little storm!

Historic January blizzard that dropped ~3 feet will always be one to remember and nearly impossible to top. I'll never forget how badly the Boston Mets busted, changeover to rain never happened and we just kept snowing.

While I appreciate the RPM runs, they appear to be out to lunch this winter. Perhaps I'm blinded by rose colored glasses, but I don't remember it having such a hard time with thermals and corresponding ratios quite like this winter.

Yea, temps down on Cape never really dropped below 33/34 during the storm. Made it impossible to maintain strong ratios that may have existed aloft.

Nice storm! Upper Cape did well and had an extra hour or two under that band that just swung through. Near the canal could end up 8-10.

Based on reports out of Chatham, and a similar temp battle all storm, I can’t imagine they’ll end up with anything more than an inch or so of slush (if that).

Last burst down on Cape Cod

Should be an exciting few hours. 4PM to 6PM crush job for those near the canal was well forecasted by HRDPS / HRRR.

Solid bands delivering down in Barnstable, MA (Cape Cod)

Heavier stuff moving in down south. The unknown is how rates will translate.

Current conditions on the Cape

4PM to 6PM is where the Cape will get their best rates. HRDPS says it should be around 2” an hour.

31 to 40 down on Cape Cod in two hours

Outside of the NAM, it seems that most meso / major models have significantly pulled back on QPF output. Baring an overnight shift, looks like 2-4 is more likely for Boston, with points south in the 3-6 range, and 4-8 from Plymouth, MA down through upper Cape Cod. Unfortunate given the potential, but at least we have few additional clippers to monitor over the next few days.

Would have to imagine proximity to the ocean & the influence of those easterly winds off of the water. If you were on the water all along the north/south shore you were toast.

Only took until 10PM for Boston snowfall to actually start accumulating. Too little too late I'm afraid.

Understanding how unlikely this EURO output is, we'd be looking at a 54 hour snowfall event for SE MASS. First shot would be from 0z to 12z Tuesday, with a brief letup in precip intensity, and then a decent pickup with the north wind / ocean enhancement from 6z to 12z on Wednesday.

Sleet/mix confirmed via personal webcam on Cape Cod. Solid 5 inches for central Cape areas. Likely a bit more out to the canal and less to the outer Cape.
