Winter Weather 2017-18 where EVERYONE argues.

Just replaced a solenoid on my generator and made sure it starts now. It’s supposed to get windy here on the coast (I’m on Mount Desert Island, just off the coast of Maine). We’re projected to get 12-16” of snow and gusts of 60+ mph

Waves? Tides?

THUNDERSNOW???!!!!

The good news about the blizzard is it warmed up today. I wore my light jacket today; it was 12F when I got to work. It felt pretty nice. My face didn’t hurt on my walk in. Eventually it got up to the high 20s. After we get dumped on it’s supposed to drop back down to zero (real, not with wind chill) for the weekend (when I want to be out skiing in the new snow)

It is possible to be too cold to snow. Weird, huh?
 
Re: Winter Weather 2017-18 where EVERYONE argues.

Today was gorgeous out. Did a quick swing outside to check on an installation when I was down at the plant. The sun felt so good. It was totally bearable without a jacket even though there was a breeze and it was single digits.

A bit windy on the west side where I am, but yeah, that sun helped.

This startribune headline confirms what Brent said :

The deep-freeze free-fall that began Christmas Day made the final week of 2017 in the Twin Cities the coldest in 132 years with an average temperature of 3 below zero.
Wow. You don't see that very often. (Brent being right, I mean.)

"Cold for Minnesota" is a pretty scary thought.

I mean, he's not wrong under the vast majority of conditions. Obviously if you have 100% humidity at -100 degF and it drops to -125 degF, it's going to snow as the moisture in the air falls out. It's not going to be very much snow, but it's going to snow in some form.

"Cold for Minnesota" is a pretty scary thought.

Honestly, it wasn't even that bad in the Twin Cities. Up north in Ely or International Falls, that's a different animal altogether. Or even in the Dakotas.

There was an awesome blog post written by someone living in Alaska when the temperatures got down to -60 degF (maybe even as low as -80 degF). The one thing I still remember is that he said you had to be careful at those temperatures because the tires on your car can shatter unexpectedly.

I just remember a few years back when we had an arctic blast of winter that lasted for a week or so. In the middle of that arctic blast we received some snow. The meteorologists were all on the air explaining that the old axiom "too cold to snow" is simply not a real thing. While it's rare to get snow during -20F weather, it's not impossible, and that there is a history of it.

There's a big gap in the "this is too cold for people" spectrum between traditionally warm and cold places because in the latter people are prepared. When they go out in South Carolina when it's 25 in their normal winter clothes they genuinely are too cold, because they've got at most a long sleeve shirt and maybe a crappy raincoat. In Ithaca you've got layers and a good hat and warm gloves, so even at -10 you're not happy but you're doing OK.

Plus, they never learn what I learned my first winter in Ithaca trudging up Libe Slope in a f-cking lateral snow storm: the Paul Atreides Technique. Don't stiffen up but let the cold just pass through you like you're not there. Relaxing into the frigid cold was highly counter-intuitive when I first thought to do it, but it's my secret, anyway: don't fight the cold; join it.*

This has been your Moment of Zen.

I thought "too cold for snow" was really about a lack of humidity. There are temperatures which can't support enough water vapor to form snow. But that could be a complete myth.

Eh, it was bad here. My dog fell over trying to do her business and can’t say I blame her.

Didn't Twain say something like "The coldest winter in my life was a summer in San Francisco?"

Having lived three years in a log cabin at the top of the Santa Cruz Mountains not far from the City, I can say that 35 damp and windy degrees often felt like zero.

were you writing a manifesto?

Some weird situations in Boston area due to the blizzard following extremely cold weather. We've got "slurpee waves" and ice shrapnel. Needless to say, there are folks out sightseeing and surfing.

That's exactly what I do. Just relax and let it go. I have no idea if it's complete bullsh|t, but if I had to guess it has to do with your muscles tensing up and your blood being restricted. Doesn't give a chance for your body to heat itself.

I think your comment at the end probably isn't too far from the truth either.

That's exactly right. Air can hold an asston of water. But it decreases exponentially as you approach absolute zero. I think at around -20 or -30 you can hold something like .2 lb of water per x,000 cubic feet of air. That might not be a lot relative to water capacity at 100 degF, but it's still something. The biggest thing is that you also have strata of air pockets. Look at a sounding diagram and you can see that the air above the ground can be warmer and more humid than the surface temperature. As the strata mix or exchange energy and water, snow can easily happen even if you're at a very low surface humidity.

More on soundings: Link

ETA: This is why I have learned to really like advanced weather sites that go beyond "Here's our custom 'Feels Like' temperature that scales from 'It's a *** bit nipply' to 'Oh dear...'" :rolleyes:

Shut up and give me the numbers. A good way to know a good site from a bad site is whether they give you humidity in relative humidity or dewpoint. If you get RH, find a new site.

There are also more advanced variables like CAPE, lifted index, CIN, and many more that can give you a far better idea of what's coming and the potential than "Looks like ran, Hal"

What sites do you use? It used to be you could get the raw numbers from the news broadcasts and newspapers, but they've dumbed down their content over the past 20 years.
