The State of the Atmosphere: Sunday, February 10th, 2019

The next system to fly across the state will do so tonight and Monday, though won't have all that much of an impact east of the mountains aside from keeping temperatures chilly. The GFS shows tomorrow morning's mountain snow:

It's not expected to be all that much snow, even up high. Currently no winter weather highlights are issued for the high country, but travel will likely be tough at times late tonight into midday Monday with those snow showers.

Across the eastern plains we may see some mixed precipitation develop late tonight and Monday morning as well, which could cause some icing on roadways if your travel plans take you east into Kansas. The 3km NAM shows this freezing precipitation potential across the far eastern counties of Colorado early Monday, with snow pushing into the high country:

For the urban corridor... the weather over the next 48 hours is expected to remain mostly uneventful. Windy from time to time, and chilly (highs in the 30s again on Monday), but otherwise mostly quiet. If you see a flurry or two tonight or Monday, we don't expect it to amount to much, but an icy patch or two is not out of the question.

Temperatures moderate some Tuesday and Wednesday across the state ahead of the next system. Right now Wednesday looks like the pick day of the week for temperatures, with highs likely to climb into the 50s for Denver. The GFS shows the quick shot of average to above average temperatures Wednesday for much of Colorado (top) ahead of the next shot of cold air Thursday night into Friday (bottom):

You'll be hard-pressed to find a model that brings much snow to the Front Range Thursday into Friday as this system's best energy is forecast to graze the northeast corner of the state. That said, it's a number of days out, and looks to pack a decent cold front with it... so one to definitely keep an eye on. For now will add the mention of rain/snow showers to the forecast by Thursday, but not much more for now, as well as those cooler temperatures to end the week.

Snow or no snow east of the mountains, we are likely to see another good round of snow for much of the high country by Thursday, just in time for the weekend:

As we've said many times here to start the month, a chilly pattern to be sure, and a great pattern for rain and snow across much of the Western United States, but if that will equate to snow east of the mountains is a bit of a wait and see. For now the storm track favors the mountains more than the urban corridor, but it's an active one, so let's not sleep on it either.

The PNA is set to remain negative through the next 10 days:

With some milder days mixed in, but overall a colder than average look to our weather for the foreseeable future:

We'll keep an eye on Thursday and touch base soon.
