CCHurricane

00z GFS has winds gusting at least +55mph out of the north throughout Cape Cod for over 24 hours. At it's peak gusting 75-90mph for +12 hours. Trying to find a trustworthy archive for wind data, but I would have to believe these would be the strongest prolonged sustained winds experienced since Bob in 1991. Toss in one of our wettest summers on record (using Boston data as proxy), full foliage, and a lack of meaningful pruning by mother nature in +30 years, and this would be a borderline disastrous outcome for north facing coastlines from Boston points south, and all of Cape Cod.

Imagine the Hurricane of 38’ happening today!?

Meteorologically speaking, this will likely deliver a once in a lifetime event for the area. Almost 100 years since the last Category 2 made landfall in the area. From a relative perspective, and while you never wish for a major hurricane to impact people's lives, yet thankfully this event will occur across some of the least populated areas of Florida. Posted in the Tropical HQ thread: ------- One for the history books if Idalia makes landfall as a major. Also looks like relative to history, the area has been long overdue. Apalachee Bay Hurricane Landfalls Hermine (2016) - Category 1 Alma (1966) - Category 1 Unnamed (1941) - Category 1 Unnamed (1935) - Category 2 Unnamed (1899) - Category 2 Unnamed (1886) - Category 2 Unnamed (1886) - Category 2 Unnamed (1882) - Category 1 Unnamed (1880) - Category 1 Unnamed (1873) - Category 1 Unnamed (1867) - Category 1 Unnamed (1852) - Category 2

Alma (1966) and the Unnamed Hurricane in 1886 are really the only two storms with a similar origin / track. Obvious not statistically significant, yet both storms only maintained or weakened upon their approach to the area, neither strengthened. The current climo is of course different than the past, particularly the extremely water temps, so we'll wait and see what happens with Idalia.

Correct, the statistical overview (chart) and first bullet point represents at least Hurricane strength at impact. Really interesting conversation either way, particularly related to memory and behavioral biases!

The recent 30 year period has definitely been frustrating, but the frequency of landfalling Hurricanes in New England is far more frequent than once every +25 years. Perhaps the recent 30 year period represents a structural shift due to climate, or maybe the 1850-2000 period was an anomaly in terms of being far higher than normal. Regardless, the current drought between Hurricanes (32 years since Bob) represents the only time since 1850 that we've waited more than 25 years between landfalling hurricanes. Between 1850 and 2000 New England was impacted by 18 landfalling hurricanes (once every 8 years). Considering tropical systems more generally to include tropical storms alongside hurricanes, this balloons to 40 landfalling systems (once every 4 years). ----------------

Some of the most unique thunder I’ve ever heard rolling across Cape Cod. Sounds more like dynamite. No “crack” and lots of what I would describe as muffled rolling booms due to what I’m guessing is spotty precip echos between? Interesting stuff.

Peepers out in full force down on Cape Cod.

And here I thought a conservative 2-4 call was right for Boston...looks like even that was optimistic.

Any Boston peeps on to share how this band is performing?

Wouldn’t shock me if this delivers a top 5 all time 24-hour snowfall here at Stratton. River of moisture straight from the storm didn’t stop all day. Doesn’t look like there’s a direct comparison within the xmACIS2 database, but +30” in less than 24 hours...this storm delivered the goods. Any database that I may not be aware of?

Honey...where did I park the car? Stratton, VT

Just won’t quit. Groomers will be heavenly tomorrow.

First foot or so was a bit heavy, saw a few people searching for lost skis while on the lift. Second foot felt much better. Conditions on Upper Standard was the run to hit on repeat throughout the day.

+24” here @ Stratton

Agreed with a 3-6 / 4-8 outcome for metro Boston. Hard pass on StormVista’s 18-24 outcome

Agreed with haves and have nots...but a 300-400% different across eastern MA areas makes me question Storm Vistas output as a whole.

Odd, Pivotal is significantly different along the east coast of MA. I’d wager something is off with Storm Vista if only for the super odd and sharp gradients across multiple locations.

BOX isn't buying the thermals, both NAM and GFS graphics are outputting a heavy dose of "snow" yet it's falling with temps hovering around 32-34. Not sure how well snow growth would be in those conditions, while also considering the significant rain that will fall beforehand. Gotta love their "1-6 inches of snow" range on the Advisory. What could have been with a decent high to our north...

Cape Cod

Chaos. Weekday skiing is in a league of its own.

Current look on Cape Cod. Decent flakes falling.

Wet snow beginning to stick on grassy / ground surfaces down on the Mid-Cape.

Last gasp before some afternoon sunshine... Barnstable, Cape Cod
