The State of the Atmosphere: Sunday, April 26th, 2020
After the record cold and plentiful snow we saw to start the month across much of the urban corridor and Front Range, the last days of April will be summer-like across the state as very warm weather will take over for much of this week. The official month-to-date snowfall total for Denver is just 3.7", below the long term average of 8.9" for April. Still, this is hardly representative of what we've seen in other Front Range cities this month (and really much of Denver proper itself), and did ma

Snowiest season on record for Boulder as latest winter storm drops more than a foot of snow across parts of Northern Colorado
An incredible snowfall season for many locations along the Front Range continues with yet another heavy snowfall event last night and this morning for some. No place has this been more true than for Boulder. We're working on a post that will go a bit deeper in snowfall stats across the region and state, so look for that soon. This morning the Boulder topped 145" of snow on the season, breaking the old record of 142.9" set back in the 1908-09 snowfall season. Boulder recorded 11.6" of snow throu

Is a boom snowfall for Denver on the table? A look a the latest data
There's been a lot of excitement (good and bad) around some of the GFS modeled snowfall forecasts with the snow event tonight and tomorrow. While its been producing some impressive totals for not just Boulder and Fort Collins but the entire metro Denver area... just how likely is this to occur? For reference, below is its 18z forecast. It has 10 - 14" across the Denver area, with upwards of 15" for Boulder, and an east to west 8 - 12" up around Fort Collins: Crazy, right? MOST other data cont

Another round of snow for the region is quickly approaching. We still see some pretty notable differences in the data as to how much snow we can expect, but general consensus is for another accumulating snow event for the Front Range foothills and adjacent plains. The latest HRRR shows snow on the increase across the northern and central mountains this afternoon, with some rain and snow showers spilling onto the northern urban corridor by late afternoon: By 9pm this model has widespread snow f

Monday PM update: Impressive snow totals for some so far, more on the way
More snow is in the forecast even as some areas have already seen more than their fair share. As we opined on Saturday, "the Boulder area the most likely to "feel" like a good storm from this one" and I'd say this morning that this was an understatement –– some parts of Boulder county are approaching 20" of snow as of midday Monday. While others haven't seen much accumulate, even parts of the Denver area have done quite well. Our station, located in Denver West has picked up nearly 7" of snow

Saturday PM update: Quick update on the cold and snow, a big change on the way!
A quick post this afternoon as we want to get out and enjoy the warm weather while we can as well. Not a whole lot of change to the general idea we've been discussing for some days now: much colder weather is on the way to end the weekend, and off and on snow is in the forecast Sunday through Tuesday. We'll see a pretty good chance of snow across the northern Front Range Sunday morning, with scatter snow showers and gusty winds sticking with us into Sunday night. A secondary wave of more organi

Weekend outlook: The cold returns by Sunday, a chance of snow as well
We hope everyone is enjoying this stretch of beautiful spring weather. We have one more pleasant afternoon to go before sharp changes arrive for the latter half of the weekend. If you have plans for a back yard Easter egg hunt, you may want to consider moving it to Saturday, as Sunday will be quite chilly with areas of snow across much of Northeast and East-Central Colorado. The outlook shows just how big a crash in temperatures we're anticipating over the coming days. From the low 70s today, t

Wednesday PM update: showers in the forecast to end the week, bigger changes by late weekend
Our mild weather will hold for a few more days ahead of some bigger changes in store for the latter half of the weekend. While mild, we'll also see an uptick in showers across Eastern Colorado to end the week. A look at the outlook for Denver shows about a 20 to 30% chance of showers Thursday, Friday, and Saturday, with highs cooling into the 50s on Thursday but warming into the upper 60s again by Friday. You'll note in the five-day the much colder air that's in the pipeline for Sunday. We tal

We've found ourselves in a bit of a pattern over the last few weeks, one that is likely continue for the week ahead as well. That is, warm and quiet weather to start the work week, with a cooler and more active weather pattern to end the week. As we move further and further into the spring, those warm days become warmer and warmer with each passing week , but still cold and snow lurks. In fact,

A chilly end to the week, some rain and snow for Denver, Eastern Colorado
This morning we talked about all the nice weather we have to look forward to in the coming weeks. Tonight we talk about changes to that nice weather, as a cold front and some rain and snow will quickly erase what was a very mild start to April today. While perhaps not a huge storm by April's standards , the changes

Friday AM update: Snow will be heavy for some, a miss for others
We continue to track rain and snow chances as the day progresses and into the overnight hours tonight. Snow is already falling across the northern Front Range mountains, and this activity will slowly expand across the urban corridor and Northeast Plains through the afternoon hours. While many of us likely won't see all that much snow, a period of at least briefly heavy snowfall will be possible this evening along the urban corridor. For areas south and southeast of Denver a more impactful event

End of week storm will bring another round of rain and snow to Colorado
After another mild afternoon Thursday, a cool down and a chance of rain and snow return to the forecast for Northeast Colorado to end the week. While at the moment it doesn't look like it'll deliver nearly as much snow to most areas as last week's storm, it's not to be completely written off just yet either. Most guidance has the heaviest precipitation well east of the urban corridor, with perhaps some sneaky snowfall across the Front Range foothills and Palmer Divide on Friday and Friday nigh

Snowfall totals as flurries continue today, rain and snow showers possible Saturday
Yesterday's storm has departed, leaving in its wake a blanket of snow across the Front Range and eastern plains. While we continue to see those chilly temperatures and pockets of snow/flurries this afternoon, the appreciable snowfall is over. Another coating to 1" will be possible for those that see these showers, but otherwise just a cold start to spring across Northeast Colorado. At our place, we picked up 5.75" of snow, right within our low-end 5 - 10" range forecast issued for west Denver.
Forecast Update
Winter Storm and Blizzard Warnings issued for Northeast Colorado ahead of Thursday snow
For the Denver/Boulder/Fort Collins corridor a Winter Storm Warning goes into effect Thursday morning and remains in effect through Thursday night. For Castle Rock, and most of the Northeast Colorado Plains, a Blizzard Warning is in effect for the same period. This is not to say the Denver area won't see wind –– but the strongest sustained winds will likely be east of I-25 and across the Palmer Divide. Still, even for the Front Range urban corridor, the heavy snow and gusty winds will reduce vi

Snow, heavy at times, on Thursday for Denver and Front Range
We continue to track the arrival of a strong storm system late tonight to impact your day Thursday with blizzard conditions to come for many. Rain, snow, and strong winds will be the story tonight through Thursday, with chilly temperatures –– and even some snow –– lingering well into Friday across Northeast Colorado. The hourly planner for Denver shows the steady increase in showers (perhaps even some thundershowers later today!) expected through late today and tonight, with temperatures gradu

Winter Storm Watch posted for Northeast Colorado: Forecast update
We continue to track a weather maker due to impact our weather Wednesday evening through Thursday night. It's likely that we'll see both rain and snow with this event, along with gusty winds and reduced visibility at times across Northeast and East-Central Colorado. In anticipation of rain changing to snow on Thursday, the National Weather Service has issued a Winter Storm Watch for Northeast Colorado, where several inches will be possible –– especially at elevations west of I-25, and across th

While some of us will see fog and drizzle overnight tonight and Tuesday, we continue to track a larger storm system due to arrive for the latter half of the workweek. Data do not show a tremendous amount of change from how things looked yesterday. Models continue to track the system more north than south, putting the Palmer Divide, northern urban corridor, and far northern Plains under the heaviest

Persistent fog and drizzle has clear most of Eastern Colorado this evening, though the far Eastern Plains and Western Kansas will see areas of dense fog through tonight and into Monday morning. Along the Front Range a mild Monday is on tap. Highs will be near 60°F (perhaps into the low 60s for some), with mostly sunny skies for most of the day along the Front Range. By Monday evening and overnight we see a bit of a disturbance move through and bring areas of patchy fog and light rain. It shoul

Thursday AM update: Rain and snow across much of Colorado on Friday, won't amount to much for the Denver area
As we've discussed both in our SOTA this week and midweek Insider update , tomorrow brings our next chance of rain and snow to the state, with some slushy accumulation possible for some across Eastern Colorado. While it does look like we'll see snow on Friday (perhaps some rain too) in Denver, the chance it accumulates looks low. Tonight some freezing drizzle could work to put some ice down on raised surfaces for your morning commu

The warmth that has come with March will continue for much of the workweek, and as far as moisture, we are watching for the potential for some to arrive late in the week. For the first week of March, temperatures were warmer than average other than on the first. The first is also the only recorded precipitation for the week, and that was only 0.03" at Denver International Airport where official records are kept. The warmer and drier pattern of March is clearly different than what the area had

Weekend update: Mountain snow and some rain for the plains on Sunday
A system moves through Sunday to bring some rain and snow to the state after a very mild and dry Saturday across the region. This is not expected to be a hugely impactful storm anywhere across the state, though winter travel conditions should be expected at times across the high country (especially the passes) on Sunday, and spotty thunderstorms across the Plains will also be possible.

La Niña potential later this year?
We haven’t had to talk much about La Niña during the past few years. In fact, we haven’t had much problem with it for quite some time. There are, however, a few signs that show the Pacific cooling down a bit, and that is always something that piques my interest. Just as a refresher, La Niña is the abnormal cooling of the equatorial Pacific Ocean. A stout La Niña may look something like this from 2011: Notice all of the “blue and green” scattered across the Pacific between South America and In

Snowfall totals as storm departs, and warming up for the remainder of the week!
The biggest issue with yesterday's forecast is the band of heaviest snowfall ended up about 30 miles south of where we thought the highest probability of its occurrence would be. Otherwise, things went about as expected –– timing and totals were spot on. The heaviest snow band was indeed able to produce totals of 4 - 7" as we expected it would, it just ended up over the south side of the Palmer Divide and Colorado Springs metro area instead of up north. Where we didn't see the more persistent h

Rain and snow back in the forecast for Denver, Northeast Colorado tomorrow
If you look to the west today you'll notice a lack of clouds along the Front Range foothills, even as most of us across the urban corridor are under a thick cloud deck. This is called a mountain wave cloud, and will likely be responsible for holding back temperatures a good 5 to 10 degrees below what they could have been this afternoon. From above, it's quite easy to pick out this feature on satellite. At the mid levels we see a westerly flow across the state, with the bright white wave cloud (

A snowy February comes to a warm end, March begins with a chance of snow on Sunday
February 2020 will end colder and snowier than average for Denver, and really much of Colorado. Denver's official snowfall for the month will end at 16.5", more than double the average of 7.7" for the month of February. This brings the season to date snowfall total to 46.4", also well above the average to end February of 35.1". For temperatures, the month looks to end well below average, even with highs expected to push 60°F today in Denver. Mon

Tricky snowfall forecast for Denver, Colorado Springs, as winter storm arrives tonight
It's cutoff low season, and with that comes a good amount of uncertainty with large storm systems that swing through the Four Corners then into Southeast Colorado and the Texas/Oklahoma panhandles. These systems are often big snow producers for the Front Range and urban corridor, as they are powerful, often slow-moving systems that can tap ample moisture as they move east of the Rockies and strengthen. Whether they produce copious amounts of snow for the Front Range or not ultimately depends o
