Mt. Washburn view from Yellowstone NP. This particular webcam is mostly in the clouds these days, even with the general lack of snow. The other web cams show some non-snowy ground at the entrances to the park North Entrance- Electric peak

With some temperatures in the 50's coming up, this 11 degrees below normal is going to get wiped down to being just a bit below normal, maybe

Some more very high winds of 60-110 mph in Boulder

The sun is now burning the other side of the Earth! So terrible for them.

One of my ideas is that La Nina slows down the subtropical jet and enhances the polar jet along the US-Canada border (going into winter months) You can see on this chart the 30-day 250mb jet stream has been much less westerly than normal from Hawaii to San Francisco, which makes lots of sense with this idea. I also think the La Nina leads to greater wind events for Colorado. (Like today) There is definitely an upper level ridge in the averages, over the Pac NW, leading to lower precipitation out West. And a large Greenland block-Labrador Sea block.

Boulder probably had some trees down today

we got all sorts of wind and fire out here! (probably not that much fire)

I don't think I've seen much rain in Montana in winter

I forgot to mention this yesterday, but one of the Glacier National Park web cams had water drops, that is, rain. That is a result of such warm air.
