KAREN LEIGH: Rain right now. Others, it's snow. Or a mix of the two. But by tonight, most of us can expect all snow. And it's going to be really, really cold.

The Mobile Weather Lab showing us what the drive is like already this evening. In Boulder, it's been all snow for a while now. And the city is on accident alert tonight because ice of course, is going to be a concern for many sections of roads out there the clouds and fog hanging around most of the day today.

Good afternoon. Thanks so much for being with us tonight. I'm Karen Leigh. We do have team coverage for you this April snowstorm. Jamie Leary tracking the wind and the snow for us in the high country. Meteorologist Lauren Whitney of course, with snow totals that are expected. We start, though, with Chris Spears live in Loveland with the Mobile Weather Lab.

CHRIS SPEARS: Well, good evening, Karen. It is snowing in northern Colorado. It has been snowing for a few hours. And just take a look. We have about 1/2 inch already on the ground.

Traffic a big concern, of course, with the cold temperatures. This is Interstate 25. At this point, we are in decent shape. The roads are wet, but not terribly snowy. And that is due in part to our high April sun angle and the longer days.

But this is why we are worried. We had a little bit of freezing rain, as you know. Some of you still getting it. So you'll definitely see some ice accumulation on objects. And there is a little bit of water on the roads that will likely freeze.

We've also had a little bit of wind. And we'll see some occasional bouts of wind coating things like signs. Let's go over here to the Weather Lab.

We had the cold front come in early this morning, putting you into the fog and the drizzle. This is the main action, though. It is a secondary surge of cold air. It runs from about Sterling to Fort Morgan to Boulder. That is what is going to bring the snow into the metro area. And for more on that, meteorologist Lauren Whitney in the Outdoor Weather Lab.

LAUREN WHITNEY: Well, yeah. You can see it's.
