Threats
The Snow Scale is unchanged from yesterday’s outlook. My confidence is still pretty high that we’ll see snow flakes fall on Christmas Eve. I’m also rather certain that it won’t accumulate to much. Depending on today’s data, I may increase my confidence even more, but the amount of snow will likely stay below one inch. Data up until now has strongly suggested around a dusting to one half inch. We’ll see if anything changes today. Still, it will be nice to see some snow flakes for the holiday!
Also, be aware that some very cold air is coming with this system. Make sure outdoor pets and plumbing are taken care of before the cold air gets here!

Almanac
Yesterday’s National Temperature Extremes
High: 87° at Chino, Pala, & Woodland Hills, California
Low: -10° at Gunnison, Colorado
Today’s National Wx Hazards
Snowflakes will accumulate today across parts of New England. We’ll also see snow piling up along the northern tier of the US border, as well as across the Front Range of the Rockies, the northern Rockies, and the mountains of the Pacific Northwest. A lot of White Christmases this year!
Tomorrow’s National Wx Hazards
Accumulating snowfall will be found across the Upper Midwest, as well as across western Colorado. Very heavy snow could fall across northern Minnesota and Wisconsin, possibly stretching into the Upper Peninsula of Michigan. The blue-shaded areas represent rain mixed with snow, with little to no accumulation. A wildfire danger increases across southern California.
Weather Shots
I snapped this pic yesterday evening, while waiting on the sun to set. I love the geometry the tree limbs create! I hope you all had a chance to see the conjuncture of Jupiter and Saturn after sunset! If you missed it go out this evening. It will still be a cool sight to see! Just look southwest after sunset.
NASA Nerdology
Have you ever thought about what equinoxes and solstices look like from space? In 2010 and 2011, SEVIRI on Meteosat-9 captured these 4 views of how sunlight fell on the Earth during the winter solstice, spring equinox, summer solstice, and fall equinox. How cool is it that we get to see such images?
