Friday morning, the city has seen slick and dangerous roadways throughout the day. Though more snow is not likely this evening for the city itself, higher altitudes surrounding the city may receive a second round late Saturday morning and into the early afternoon.
As cold air continues to drive southward, the first snow of the season has arrived for the Denver area.
There could be enough snow and falling temperatures to make for slippery spots into Saturday.
Advancing cold air will turn uphill along the eastern Plains and along the Front Range of Colorado this weekend, just as a disturbance in the upper atmosphere comes sailing by.
The combination of the two may be just enough not only to bring the first snowflakes of the season, but also the first accumulating snow away from the high country. (Last month, pockets of chilly air aloft brought a bit of snow to the some of the high country of the Rockies).
A few inches could fall on some of the foothills and the east-facing slopes of the Front Range.
During Wednesday, the first snow away from the high country fell on portions of Montana and western North Dakota. That storm was clobbering eastern North Dakota, northwestern Minnesota and neighboring Canada Thursday.
Other cities that could experience a bit of snow and slippery travel areas include Colorado Springs and Cheyenne, Wyo.
Much colder air will push in during and following the snow, setting the stage for a freeze and an end to the growing season for folks with vegetable gardens and flower enthusiasts.
A Blue Norther will sweep across Oklahoma and Texas into Saturday.
Some of the higher elevations of the Northeast could also receive their first snow of the season later this weekend from part of the same disturbance.
This will not be the earliest snow on record for Denver. That title belongs to Sept. 3, 1961, when 4.2 inches of snow fell.
According to the National Weather Service in Denver, there has been snow as early as Oct. 5, 2001, and Sept. 23, 2000.
The average date of the first measurable snow is Oct. 25.
More clouds and cooler weather can be expected across the Bay Area through the holiday weekend and into the new week.
Cloudy skies and cooler weather will linger across the Los Angeles area through the holiday weekend and early in the new week.
It might feel more like late October rather than late May in the Northeast on Friday night as temperatures dip well below normal.
Memorial Day marks the unofficial start to summer and summer warmth will dominate the Northeast next week, but that does not mean an end to shots of cooler air.
Showers and thunderstorms threaten to interfere with Memorial Day festivities across roughly two-thirds of the United States.
Another round of downpours and thunderstorms will bring a renewed threat for flooding from Kansas to Texas over the Memorial Day Weekend.
