it's called the atmospheric river. it's a river in the sky. it's a plume of moisture that continues to bring in the very heavy rain. you can see the darker colors here, the greens, yellows, oranges indicating that rain is falling. so we do have a flood threat because we have the be burned areas in many spots in southern california. that's the concern over the next several days. this is a set up. we had the first area of low pressure come through yesterday. now it moves to the four corners. they'll -- we'll have the another storm on christmas day. it will bring high elevation snows. we're bringing in 8 feet in some spots. that's a lot of snow in the highest elevations of the sierras. we're looking at snow in the cascades. lots of cold air in place. we could see snow possible in seattle, rain down into san francisco. chris, in the contrast, as you mentioned before, looking at summer-like weather in the central and southern plains. a lot of people barbecuing. the temperatures in the mid 80s. >> barbecue for christmas. michelle, thank you! happy holidays. >> how crazy.
