Labrador and the Hudson Bay today at 2 pm Eastern Time.
Only the immediate maritime areas of south-east Hudson Bay appear to have any maritime moderation left. The south-easternmost parts of Labrador also remain above freezing courtesy of seasonal lag. The writing really is on the wall with that, due to the interior cold sweeping towards the coastline. Happy Valley-Goose Bay is already at -10°C even as the coastline is above freezing, for example. Also for Mary's Harbour, a settlement in that area, the temp above freezing is a long way above the -5/-14 December normals.
Would love to know what program or site you use for those observation maps.
I use a software of mine I pay for annually. GREarth. You can use this. It's free and the same thing. In fact you can change the color of the temps to whatever you want.
Maybe things will get interesting for the deep South as we enter into January.
Last night's GFS runs showed snow over central LA on Jan 3!
Maybe.. I think we'll have to wait till after beginning of January for the south. We'll see.
Looking ahead looks like New Years Eve there's a storm to watch for.
For those that don't know, on the Tropical TidBits site you can click "Previous Run" and it will show you what that model had for that same time frame.
So for instance.. Here is todays latest run of the Euro model for New Years Eve. It has the storm over South Carolina with the freezing line at 5000' south of Kentucky.
lets see what it had yesterday
It still had the storm (1011mb) but faster since its off the Carolina coast at the same time frame (New Years Eve). Jet stream digging much more south with the freezing line down to Louisiana.
Lets see what it had with the previous run.
3 days ago it showed the storm not far off the Long Island coast. So new runs keep the storm south and out.
Anyway - Still a week away, lets see what happens. Might not be anything big. maybe a streak of snow across the U.S but could be pretty for someone for New Yrs Eve. (sucks for travelling)
Mt. Washington still has a bit of snow: rainstorm decreased the snow pack from 18 inches to 2 inches. Down in the valley at Pinkham Notch it went down from 12 inches to 7 inches, wonder why? Rainfall amounts weren't higher at the summit (3.5" at the notch, 2.94" at the summit), temperature inversion at the first part of the storm meant warmer temperatures on the mountain. Whitefield just outside the mountains only one inch, so the effect of the mountains increasing precipitation is more from being in the mountains rather than high up. Map of snowpack this morning:
I'd say the pollution is still primarily human-caused. Southern China still gets quite a bit of pollution despite getting more winter rain. What really needs to happen is to eventually remove the old factories that add the pollution in the first place. Pollution has gotten less severe over the past few years (source), which is proof that it is human-caused. Temperatures are still by far the most important factor to consider when rating a climate, followed by precipitation amount and sunshine. IMO precipitation pattern is a relatively minor factor that can bring a climate from a B down to a B-, but not have a major impact.
but if you got more changeable weather, the air pollution wouldn't build as much, right?

That can certainly be true, but I tend to imagine that all climates have a fully developed economy and all factors except climate are equal when rating climates. Seattle has stable winters and it doesn't get air pollution in the winter. In fact, last year in December I remember there was an "air stagnation" alert that says the lack of wind/rain may cause air pollution. There was no noticeable pollution.
If a city like Seattle had the same climate as Qingdao, pollution would not be a significant problem. If a city like Qingdao had the same climate as NYC, pollution might be a little better but why not just try to remove dirty factories that contribute to pollution in the first place?

wasn't talking about rating climates. But yea, if there's no local air pollution than the weather patterns don't matter much. Los Angeles is much worse than NYC mainly from the air patterns; even before it was developed, LA would occasionally get mild natural smog. Northeast US gets its smog alerts almost always in the summer when heat & humidity traps pollutants more, can't remember why.
