DENVER — April 28 is the average date for the final snow in Denver. It looks like there will be a good chance for snow accumulation on that day this year. No signal showing a high chance for snow in May though. The last time there was snow accumulation in the month of May was just 2 years ago in 2019.
This blog watches winter storms develop in computer modeling.
April 27-28 (Tue-Wed)
After a nice break from below average temperatures and ample precipitation chances, a potent winter storm is due to bring wintery conditions to parts of Colorado on Tuesday.
The storm was just moving onto land in northern California on Sunday evening. It's path appears to be a very southern one, coming to full strength in southern Arizona. That will press moisture and cold air back into Colorado on Tuesday night into Wednesday morning.
Snow accumulation will start in parts of the mountains very early on Tuesday morning before sunrise, but might not reach the Summit and Front Range part of the mountains until closer to noon if this solution holds.
The storm should be able to deliver close to a foot of snow on some of the areas mountain ranges, especially the Front Range zone.
On the lower Front Range, there will likely be a round of strong thunderstorms on Tuesday afternoon. Likely the most widespread thunderstorm outbreak of the season. Probably not severe storms although some wind gusts could get close to 60mph.
The timing of the precipitation may linger into late Tuesday night into Wednesday morning, so that means there will be a good chance to get some snow accumulation in the Denver area. It also means, the foothills could get something significant.
As of Sunday nights models runs, there is about 1-3" showing for the Denver metro area and 3-8" in parts of the foothills. Probably a low impact storm though because low temps may only be in the middle to low 30's. So far, models are showing mostly a rain and snow mix with a lot of melting.
CHANCE OF SNOW IN DENVER: 20%
EXPECTED ACCUMULATION AT DIA: Less than an inch
The next system is showing around May 3. The solutions on this one so far are very warm, but it could deliver a couple inches of snow to the high country if it holds this course.
