It won’t be as bad as last week’s storm, but there’s probably more snow on the way for the Front Range later this week.
After high temperatures reach almost 70 degrees on Thursday afternoon, an area of low pressure will bring big changes on Friday, including the possibility for more spring snowfall.
This system, however, doesn’t appear to nearly pack the punch and overall impact of last week’s storm, which led to Denver’s snowiest day in four years on March 19. Last week’s storm also led to thousands of power outages in eastern Colorado due to gusty winds and the heavy, wet snow. This week’s storm does not appear to have either of those threats.
However, a slushy 1 to 4 inches of snow could be in store for the Denver area, mainly falling on Friday night.
“Thus there is some potential for heavy wet snow in some areas of the foothills, adjacent plains and Palmer Divide,” the National Weather Service office in Boulder wrote on Wednesday about Friday’s snow chances. “In the (mountains), there will also be some risk for heavier snow as well.”
After clouds and some rain showers and perhaps a thunderstorm or two on Friday and Friday afternoon, the rain will likely transition to snow around dusk on Friday night.
Temperatures will be borderline for snow on Friday night, and, coupled with relatively warm ground temperatures, it’ll be difficult for snow to stick. But, a burst of an inch or two of snow is possible in Denver on Friday night, with higher amounts likely in the foothills and the Palmer Divide. In the foothills and the Palmer Divide, colder temperatures and higher moisture values (from upslope flow, or moisture-rich winds backing against higher terrain) will boost snow totals closer to 3 to 6 inches. Travel on Interstate 25 south of Denver and Interstate 70 west of the city could be difficult on Friday night.
There is still some uncertainty behind this storm, notably around the area of low pressure’s exact positioning, and also around surface temperatures. Alterations to either of those could lead to an adjustment in Friday’s forecast.
So far this month, Denver has seen 6.5 inches of snow at the city’s climate observation site at Denver International Airport. At the city’s more centrally-located Stapleton Airport observation site, however, 10.5 inches of snow have fallen so far this month, close to the 11.4 inches of snow that De
nver averages each March.
So far this winter season, DIA has seen 52.9 inches of snowfall, which is nearly equal to the full-season average of 57.1 inches of snowfall. At the Stapleton site, 60.2 inches of snow has fallen so far this season, already making this the snowiest winter season in four years.
Worth noting Stapleton Airport site is already there, with 60.2″ of snow so far this season.
That’s already Stapleton’s snowiest winter in 4 years, and 2nd-snowiest this decade. #COwx

It looks like both of those totals could get a small boost later this week.
