Back Side of System Could Bring More Rain and Snow Over Weekend

The sun has broken through the clouds for many across eastern Colorado, but our system is not quite over yet. This afternoon we're dealing with severe weather on the eastern Plains, and as the large upper level Low responsible for bringing heavy snow and rain to the region over the last 36 hours moves east, the I-25 corridor could be in for another round of rain and snow before all is said and done.

Here's a look at the satellite imagery as of 4:00pm on Friday, with some clear skies across the plains, but still visible circulation around the Low spinning over south-central Colorado.

The best chance for precip for the Front Range urban corridor looks to come Saturday night into Sunday as the Low finally pushes east of the area. For now we expect Denver to again be mostly rain, though we'll of course need to watch the rain/snow line. This is kind of a "sneaky feature" that may produce some travel troubles Saturday night into early Sunday. It will be windy too. This could cause visibility problems from Castle Rock to the north side of Co Springs and eastward across the Palmer Divide.

For the Foothills west of town there could be another round of several inches in store for you, as well as another 2 - 4" possibly over the Palmer Ridge between Denver and Colorado Springs. Below is what the GFS is forecasting for additional snowfall through Sunday morning which looks reasonable. Short lived, but possibly intense...

For precipitation we could see another 0.3" to 0.9" through Sunday morning, with more unsettled weather possible to start the next week. Here's a look at the 18z GFS precip forecast through Sunday morning, much lighter totals than we've seen, but certainly notable after the last 24 hours.

While overall conditions are improving, please don't be caught off guard by the chance for additional rain and snow (at times) over the weekend. Temperatures will be a bit warmer Saturday across the Plains, but will cool as precip chances increase late in the day into Sunday. The general theme to keep in mind over the coming days is cool and unsettled.

We'll have a full wrap-up of this storm in a future post, for now enjoy the sun if you're seeing it and be thankful for all this much needed moisture!
