The State of the Atmosphere: Monday, June 1, 2020
100 degree heat returns to Colorado this week Hot weather, potentially record-setting, arrives across Colorado the first week of June. The heat is not only for Colorado but for much of the region. This won't be the first 100s of the year. The last weekend of May brought 100-degree heat to Lamar, CO. As we look across the region for the next week we see all of the following stations featuring double digit above average temperatures each day at this early June heat takes hold: And, of those th
Rainfall Totals
A wonderful soaking rain for much of East-Central Colorado
Sunday's system delivered some much needed moisture to many of us across the region, but left crucial regions of the state high and dry. Denver officially picked up 0.94" of rain on Sunday, bringing the month-to-date total to 1.56", just 0.05" shy of average for the month. At nearly 1", the airport was fairly representative to what most locations saw across the greater metro area and immediate surrounding areas. Some folks reported a bit more than an inch, others a bit less, but a good soaking

Saturday PM update: Latest on late weekend rain and snow
Not much change to the outlook today than what we've been discussing for several days now. A chilly and wet end to the weekend looks likely along much of the urban corridor and the northern Front Range mountains. You'll recall in our update last week , the Palmer Divide region has been some of the driest in the state compared to average thus for this month. The good news about th

Wet and, for some, a white late weekend still on track
Just wanted to update you all on the progress of our holiday weekend storm system. The following images show how much liquid and how much snow is expected from the different models. EURO Model GFS Model Canadian Model Obviously, the models have their own ideas on the finer details. However, they all agree on a chilly and wet storm system moving through most of the state from Sunday into Monday. Considering the precipitation deficit we are facing across the state, this is all obviously go

Colder with rain and snow for Memorial Day Weekend
There's a system that will move through Sunday and Monday which will bring the state rain, snow, and a few days of chillier weather. We talked about this in last week's SOTA as a system to keep an eye on, and, while its impacts have been hit and miss in the modeling over the last days, consensus is growing that we'll have some wet weather to contend with over the holiday weekend. While perhaps not

Wednesday PM update: scattered showers and storms to end the week
As we discussed in the State of the Atmosphere on Sunday, Thursday and Friday will feature a better chance for showers and storms across Eastern Colorado after a largely dry and beautifully mild midweek across the region. The heavier rainfall will be hit and miss, meaning many of us won't necessarily pick up appreciable rainfall between Thursday and Saturday. That said, the chance for rain creeps int
Drought expands across southern Colorado
For many of us in the state, this winter has been quite snowy. For a lot of mountain areas, it’s been a good snowpack year. So it might be surprising to know that some areas of our state are in increasingly severe drought. As of April 28, 32% of Colorado is experiencing severe drought (D2) conditions. How did we get here? One year ago in May, the U.S. Drought Monitor depicted a blank map for Colorado .
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

Another snow on the way Thursday: Tuesday PM update
We continue to watch yet another snow on the way for Thursday, the latest in a series of impulses to bring snow to the region. The next system appears to have potential to bring quite a bit more snowfall for some, perhaps mimicking the last system with some of its totals. The foothills west and northwest of Denver are likely to see the greatest snowfall totals from this system, barring any changes between now and Thursday. Here is a look at the snowfall totals from the last (if you need a spec

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

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
Let’s talk about the weather, specifically nice weather!
Two things are happening in our world right now. First, and most obvious, we are social distancing. We are told that we can’t go to restaurants or gatherings, but it's frequently recommended that we can still "go outside." Well, luckily, the other thing that is occurring is that we're in the spring season. The season of new growth, flowers budding, snow becoming rain, longer days, warmer days. Climatologists refer to March 1 - May 31 as spring. But if you’ve lived in Colorado for more than 1 ye
Denver Forecast
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
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
Snowfall Forecast
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

Winter storm will bring rain and snow to portions of Colorado Wednesday night through Thursday
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

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. The animation below shows the rain and snow dropping out of the Northern Rockies tonight, then sliding across
Snowfall Totals
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
Snowfall Forecast
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

Snow squalls shut down parts of Colorado, more wind and snow on the way Tuesday
Snow squall warnings were issued across much of Colorado Monday morning as powerful, short-lived areas of intense snowfall and strong winds raced across the state. In Aspen, an incredible example of how quick these squalls move in, and just how heavy the snowfall can become in a matter of moments. The Aspen Roundshot cam captured the impressive snow squall that moved through just before 8am in stunning images: 7am

Snow falling across Eastern Colorado, but marginal temperatures and February sun to dampen impacts
Everything's running about on schedule this morning as our upper level low begins its trek east across Southern Colorado, and our surface low establishes itself across Southeast Colorado through the afternoon. A look at radar this morning shows moisture pushing into East-Central and Northeast Colorado, with pockets of heavy snow across the Colorado Springs region, Palmer Divide, and greater Denver metro area. The bright greens in the animation below indicate the heaver precipitation rates. T

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
