It's tough too because the ocean is pretty vast, good ocean/lake effect needs land nearby to focus the lift within one or two dominant bands. That's why this is performing so well. LI/CT shores are confining the band to its current location and it just waffles with the wind direction. But in big arctic outbreaks you see the streamers from cold air pouring off the continent but they rarely organize into single dominant bands, they organize into smaller convective rolls. You can get some that are more dominant, but usually because they originate from a water feature bounded by land (Penobscot Bay, NY Bight, Narragansett Bay, etc). There's a reason the LES from Lake Michigan is more potent on a north wind vs. a west wind, and it's not just the longer fetch. The band parallel to the land features is just more focused.

No, it was on 8 ft concrete pads sunk into the ground. But it managed to pull one up completely.

As far as I know, the data is gone during the outage, but we had a 51 mph before the ASOS went down.

FWIW, the EF Scale suggests the lower bound threshold for cell tower collapse is about 115 mph. Plausawa Hill is 1000 ft, plus the 190 ft tower gets you almost to 1200 ft. Model forecasts around 1200 ft for CON were around 70 kt sustained, so I don't think winds were quite that high.

RIP to that transmitter. Sounds like our stuff may have been on that one.

Any Concord area weenies with a weather radio? We can't reach Plausawa Hill transmitter (162.4) and we're hearing rumors that the tower itself might have come down in the winds. Can anyone hear audio on that frequency?

I could see that being a better argument in like February if Erie remains open. It isn't usually ice covered in December, so these kinds of events can happen if the pattern is right. But if the lake starts staying open through February, you're going to have a lot more higher end events then in BUF than they used to.

Tossed. We chucked that LSR before I had a chance to nix it. I could've believed a 70 mph, 90+ is just a bridge too far.

Shoals 84 mph and MHT 72 mph really stand out. We had quite a bit in that 65 mph range. Not sure I’m buying our LSRs of 93 at Echo Lake RWIS and the PWS on the Seacoast of 82 mph in the morning.

More or less turning into Horizontal convective rolls allowing them to remain stationary like a LES streamer.

Ram Island?

BOX just had a bunch of sites hit 50 kt again with the top of the hour METARs.

LCI been down since this morning, but a PWS off Route 11 in Gilford gusted to 58 mph with that line.

Called the tower to verify and the back up instrumentation also had 62 kt.

Not the real cold front. That boundary hasn't crossed the Greens yet, except maybe in the southern part of VT.

Isles of Shoals 84 mph with the intermediate line of convection.

The HRRR had 58 knots at 20z.

Um, that might be very close to hail. At least graupel. You have convection over you right now, and it extends above the freezing level.

That's quite a run through SNE. Gets PWM back up above 50 kt.

I mean road temps are generally in the 40s right now, but it's not like the ground was super warm prior to this mild up. I don't think it will take much for those surface temps to go back below freezing.

It's going to be a White Christmas after all!

@CoastalWx I think those squally showers post frontal as because for a couple hour stretch the front is so strong that the theta-e lapse rates go negative.

Solid damage at Portland Head Light. Blown out windows, tossed pavers, and the granite block holding the bell was moved.

Just hit 51 kt at the office.
