The Front Range region has been drier and a little warmer than average so for this month. The best chance for widespread rain that we have seen in a while will arrive on Sunday. After a warm day Saturday, and dry for most areas, the chance for showers and thunderstorms increases by Sunday afternoon along with lower elevation temperatures no warmer than the 60s. We may even see a period of chilly rain or drizzle Sunday night. And yes, snow is likely to whiten up the mountains above treeline, and the snow level may drop down close to the elevations of Nederland and Estes Park.
Monday should be cool, but probably not too bad; 60s in the lower elevations after a damp & chilly start to the day. Warmer weather is likely to return Tuesday.

There hasn’t been much to write about lately since there are no big extremes in the weather. Mild weather with afternoon/evening showers and thunderstorms are expected again today and Saturday, but perhaps with less numerous showers on Saturday. Beginning Sunday we are likely to enter a much warmer period with very little chance for rain. There may be some high clouds from time to time the reduce the afternoon warming a bit, but if we manage to get a mainly sunny day, we could see afternoon temperatures reach the upper 80s early next week.

A cold front should sweep through the region today followed by a period of gusty northwest winds. There may be some periods of clouds, but the air mass is pretty dry, so no precipitation is expected. Later tonight as the winds die down and the skies become clear, temperatures will drop to the low and mid 30s in many parts of the urban corridor and high plains, maybe even some upper 20s in localized cold spots. It would be a good idea to cover up tender annuals.
Friday night and Saturday night should be a little less cold, but the risk is still there for localized frost. Dry weather is expected this weekend.

Some parts of the Front Range region will experience showery precipitation today (rain for the urban corridor). Even where it doesn’t rain there will be cooler temperatures and cloudy periods.
Over the weekend the trend should be toward less cloudy and warmer (although a brief shower can’t be 100% ruled out). Daytime temperatures should rebound to the 60s Saturday and the 70s Sunday in the lower elevations. There is a good chance that next week will see a day or two with the first 80-degree of the season. Enjoy.

As of 1:00 the leading edge of the next cold front is almost all the way through Wyoming and is expected to move south along the Front Range this afternoon and early evening. Snow is likely to develop this evening and last until tomorrow evening. The heaviest snowfall is likely to come later tonight and Thursday morning, and then taper off in the afternoon and evening.
Two things to keep in mind. 1) The track of the storm suggests the strongest potential for heavy snow will be north of I-70, and 2) snow this time of year accumulates most effectively during the night and early morning.
Most likely accumulations:
7-14″ in the foothills and mountains of southeastern Wyoming, and in the Colorado foothills and mountains north of I-70. (4-8 inches in foothills farther south)
5-10″ Broomfield, Boulder, Fort Collins, Cheyenne
3-7″ metro Denver (heaviest more likely on the northwest side of Denver.
1-4″ inches south of Denver and in Colorado Springs

After a record cold morning, today and Wednesday might seem springlike after what we’ve been through. Although temperatures will remain below average, it will get above freezing with some sunshine. It might even get above 50 on Wednesday. That should help melt the snow, but nature plans to bring more snow to the Front Range region Wednesday night through Friday morning.
The focus of the heaviest snow in the Front Range region will likely shift from north to south. Where it is snowing hardest at night or in the early morning is where it will accumulate more efficiently. So there is a good chance for a few inches throughout the region, but the potential exists for 6-10″ in and near the foothills for part of the region.
At this point it looks like more seasonable temperatures will return this weekend.
5:30 AM MDT, Monday, April 13, 2020
Unseasonably cold and occasionally snowy weather will continue until Friday, with a lull in the clouds and snow late Tuesday and Wednesday, and then more widespread snow Wednesday night and Thursday.
Snow amounts have been variable since Sunday morning, with some areas topping a total of 12″ and others far less. Today through Tuesday morning will continue to see variable conditions with some lulls and some periods of snow. Additional accumulations of 1-5″ are most likely this evening and overnight, mainly south of a line from Estes Park to Longmont to DIA.
Lull Tuesday afternoon/Wednesday
After some record low temperatures Tuesday morning, we should enter a period Tuesday afternoon into Wednesday when the clouds should thin a bit and there will be little or no additional snow
Snow Wednesday night and Thursday
A potentially significant snow is forecast to develop in the Front Range region Wednesday night and Thursday. There is the potential for 6-10″ for parts of the region. I will update later in the week. The weekend may finally see a return to more seasonable temperatures.
