A spring storm is pushing into Colorado today, kicking off a wet and unsettled start to the week. As of this morning, rain has been spreading northward from southern Colorado, with scattered showers and a few thunderstorms expected in the Denver area this afternoon and evening.

Gusty southeasterly winds will also accompany today's activity.

Rain will be more persistent in the mountains, where cooler temperatures could bring slushy conditions over the higher passes later today. For those with travel plans, here’s a look at the winter-type travel impact map highlighting potential trouble spots.

The core of this storm system arrives late tonight and peaks Tuesday. Expect rain to become widespread and heavier by Tuesday afternoon and evening. While lower elevations—including the I-25 corridor—will see a soaking rain (possibly over an inch in spots), snow levels will drop to around 7,000 feet. Above 8,000 feet, snow will pile up quickly.

A Winter Storm Watch is in effect for the higher elevations of the Front Range, including Rocky Mountain National Park, the Indian Peaks, and areas near the Eisenhower Tunnel. These areas could see 12 to 22 inches of heavy, wet snow by late Tuesday night. Travel in the mountains could become difficult during both the late morning and evening commutes Tuesday.

Here's possible snowfall, note the highlights for the Front Range Mountains and parts of the Divide. The San Juans will also have some hefty snowfall.

No, Denver is a bit too warm for a snowy impact this time, but parts of the Palmer Divide could see snow. Regardless of the froze stuff, there's a lot of water to cover Colorado in the next few days:

By Wednesday, rain and snow will gradually taper off, with drier conditions returning by evening. Sunshine and warmer temperatures return Thursday through the weekend, but daily chances for isolated afternoon storms will linger—especially over the mountains. Expect a warm-up heading into Mother’s Day weekend.
