Weekend update: Mountain snow and some rain for the plains on Sunday

A system moves through Sunday to bring some rain and snow to the state after a very mild and dry Saturday across the region.

This is not expected to be a hugely impactful storm anywhere across the state, though winter travel conditions should be expected at times across the high country (especially the passes) on Sunday, and spotty thunderstorms across the Plains will also be possible.

The animation below shows the rain and snow dropping out of the Northern Rockies tonight, then sliding across Colorado Sunday into Monday. Of note, quite a bit of GREEN in this map, even across the Colorado mountains, indicating it's a very warm system, and many of us are likely to see rain (if anything) and not snow:

The 3km NAM shows most of the snow accumulation will be confined to the higher peaks through midday Monday:

But that some moisture will spill over across the Northeast Plains in the form of rain:

Some of these showers may be convective in nature Sunday, which means some of us could see our first thundershowers of the season. The convective outlook from the SPC for tomorrow shows the potential for thunderstorms across the state as this system moves through:

The hourly planner for Denver shows the chance of showers mainly tomorrow afternoon and evening. Temperatures will be a few degrees cooler than today (we could very well break 70°F this afternoon in Denver!), but still mild overall. This means that IF you see precipitation east of the mountains tomorrow, it should be in the form of rain.

Get out and enjoy the day! Even with those rain showers on Sunday the day doesn't look like a total wash. Overall a mild early March weekend on tap for Eastern Colorado, with that mild weather expected to spill well into next week as well.
