00:00This is a Utah DOT with the snow plow cams. Love seeing these again.

00:05Although if you have to travel long distances, it can be tricky.

00:07Let's go to Jackson Hole, Wyoming.

00:09And here you can see we're at 36 degrees.

00:11Looks kind of a wet surface right now, a little bit of rain, cold rain.

00:15And there are some snowflakes at times in western parts of Wyoming.

00:19But the forecast is going to get increasingly active here to the east of this location

00:24as the snow moves farther east.

00:26So there are low elevations out near Jackson where we're not necessarily under a true winter storm

00:31or winter weather advisory.

00:32But you step away from the lowest elevations in the Jackson Hole area

00:36and you're going to get up into winter weather advisories,

00:38winter storm warnings in the deep blue across much of Wyoming.

00:41And then fire danger is the concern in the red zones here of eastern Utah,

00:46eastern parts of Colorado, I should say.

00:48In Utah, it's a mix of freeze warnings and also winter weather advisories.

00:52But the blue zones here where we're going to get cold behind this storm system

00:56and then accumulating snows falling in these winter weather advisory zones,

00:59winter storm warnings where the heavier snow is falling up into parts of southern Montana,

01:03western South Dakota into the Black Hills and also a chunk of Wyoming.

01:07So here we are with the radar, and again, the rain-snow line is nudged east of the Black Hills.

01:12So we're into the snow zone there.

01:14We have snow across parts of Wyoming into the Colorado Rockies, the Wasatch, the Uintas,

01:19the high ground in the interior west getting into it here for sure.

01:22As we jump into the current temperatures here, well, overall tomorrow,

01:26we're around 40 in Denver with a rain-snow mix.

01:29It's going to be cooler, but the current readings show that we're at 56 now in Denver.

01:33And we're still at 84 in El Paso, but we've really dropped about 15 to 20 degrees in Phoenix.

01:38The cooler air is marching in.

01:40We're down to 31 in Casper with that snow falling.

01:43And in Casper, we're anticipating between 6 and 10 inches of snow in progress now through tonight,

01:48winding down by midday tomorrow.

01:50Then we get a little break of the action here.

01:52There's going to be a brief zone of high pressure that scoots across the region here

01:57through the interior west after storm system number one exits to the east,

02:02and number two will be moving in here into Wednesday.

02:05So tomorrow, the break comes to an end in Seattle.

02:08Importantly, you're back into rain.

02:10Mountain snow will return, and this is the second in a series of Pacific storms

02:14crossing the western U.S. and marching into the northern Rockies by Thursday morning.

02:19This is Halloween morning.

02:21Snow in the high ground, rain on the valley floor southeast of Boise.

02:24We have rain and snow mixed there into parts of Washington and Oregon,

02:28high-elevation snow certainly, and the low elevations will be seeing the rain

02:31that lingers through much of Thursday.

02:33And soaking rain, the wettest weather in the nation,

02:36most persistent rain on Thursday on Halloween will likely be in western parts of Oregon.

02:41Heading farther south, here you can see we're going to be a little cool.

02:44Sacramento, only 66 degrees.

02:46That's about 8 degrees below normal for Halloween.

02:48Vegas, about 5 degrees below average, only 71.

02:51Tucson, 81.

02:52L.A., beautiful day for Halloween, 73 degrees.
