Thursday PM Update: Rain and Snow Showers For the Plains, Heavy Snow for the Mountains

Models have trended a little wetter this evening and overnight across Eastern Colorado. Still not expecting most areas to see snow, and for those that do any accumulation should be on the low end. Rain, mixed precipitation (perhaps some freezing drizzle!), and some snow across the plains however does look likely starting this evening and carrying into Friday morning.

The lates HRRR model shows snowfall totals through 3am really focused across the mountains. For the Northeast Plains we see some scattered light snow totals (generally under 1"), with the model showing a Trace - 2" over the Colorado Springs vicinity over the last several runs:

At 3am precipitation is not done across the state, though we see it gradually increasing in intensity:

For the Southwest Mountains today and tonight will prove bountiful for snow. Warnings are in place for 1 - 2' for high mountain passes across Southwest Colorado, with up to one foot for the north-central mountains through tonight.

The 3km NAM tends to agree with the HRRR. It too has a bullseye for rain/snow in Colorado Springs with a period of decent upslope later this evening for that area. It keeps Denver pretty dry:

Other models show a bit more potential for the Denver area, though as we discussed yesterday it doesn't look like a big deal for most areas. If we see some freezing drizzle, of course that could lead to some icy patches on the roads Friday morning.

The Euro is maybe most "bullish" for the Denver area bringing up to a tenth of an inch of liquid to the western suburbs, with perhaps some of that falling in the form of snow. Again, even if it's right, we wouldn't expect more than a Trace to 1" of spotty snow.

Still watching another chance of snow by late in the weekend, as well as those colder temperatures we discussed yesterday. Models tend to favor a more southerly solution with this next system... but our gamblers continue to show the chance we see some accumulating snow across the northern urban corridor over the next five days:
