Denver Forecast
Denver weather: Dangerously cold start to the week, snow for some
The cold is now the biggest talking point, as outside of the DEEP snow in the northern mountains, we mainly have dangerous wind chills to expect through Monday morning. Let me geek out first, as if I don't always geek out, but look at this live camera from Steamboat Resort , 49" this week at the summit! I hope they don't clean off the snow stakes before you can see this, but in case they do, here's a quick screen grab from early this

Colorado weather: Alerts issued ahead of extreme snowfall in northern mountains, extreme cold in metro areas
The next round of snow and cold will be quite substantial. For the northern mountains, well over three feet of snow will be possible through Tuesday, and for the metro areas, the arctic cold will set in Sunday through Tuesday morning. Let's begin with the alerts, I anticipate more but these have been issued as of this posting. Nothing is currently in effect for the Denver area, but Colorado Springs will be on the look for extremely cold wind chill values of -25 overnight tonight and again Sund

Denver weather: Frigid temperatures return with chances for snow and icing this weekend
Enjoy these Friday temperatures, and some sunshine, as we melt off a touch from recent snows, but get ready for chances of both snow and some icing throughout the next several days as the next arctic push moves in. Here's the hourly planner for Denver, showing today's warmth and then the temperature drop that is expected throughout the weekend. Along the bottom are the chances for showers. Yes, that's a slide from 46° to -2° in the next 72 hours. Will we be sliding on new snow and ice, too? Le

Western U.S. snowpack and reservoir storage update; new drought numbers are in
Considering the recent flow of moisture toward the western U.S. from the Pacific (atmospheric river events), let's check in on how the water situation looks presently, particularly the Colorado River system. Just after Christmas, a series of atmospheric rivers brought dangerous amounts of rain and snow to California during a 3-week period. So

Denver weather: Another arctic chill to move in following late-week warm-up
As temperatures rebound a bit through Friday, another push of arctic air will move through late this weekend and early next week. The swing in temperatures is shown here, from the lower 40s Friday to below zero early next week. That's cold, but considering record lows for those days are -10° to -25°, it's not that cold. No, this isn't cold like before Christmas, but it is adding to the already cold winter we have had, and month for that matter. Well, I should really say it has been a colder t

Colorado Weather: Snowfall forecast through Wednesday, Denver's next snow chance
We've discussed the cold pattern and nearly daily chances for snowfall; well, the next round of snow chances approaches for later Tuesday through Wednesday, although this timeline pinpoints the higher chances this evening. If we run the Gamblers data, it has a low-end potential for us in the city, but I'll show you the Palmer Divide where we may see some higher accumulation. "Higher accumulation" ;-) as you can see the probabilities are quite low. The Palmer Divide is shown below with a T-2" r

Denver weather: Stuck in a cold pattern, nearly daily snow chances
The past couple storm systems were able to shift the momentum, if you will, and bring in lasting cold temperatures in a pattern change to last quite some time and to provide nearly daily snow chances. Speaking of that latest storm, it's going to spread serious impacts across the country through this Wednesday. I talk about that here, but the rest of this blog focuses on the Denver area through the week and beyond. First off, temperatures. Let's just look generally at Denver for the next two we

Denver & Colorado's snowfall forecast: Impactful snow is on the way, especially north and east of the city
Our eyes remain on the system to hit tomorrow, Tuesday, through Wednesday. As we have discussed previously, the biggest impact is all up to what is now any minor changes to position and speed of the storm as it develops over southeastern Colorado. If that storm develops a touch north of its current forecast, Denver will come away with less snow, the same for the Palmer Divide and in Colorado Springs. If that storm develops a touch south of its current forecast, Denver and Boulder continue to h

January update: Death to La Niña?
It's increasingly likely that La Niña is very near the end of this latest phase as the likelihood of La Niña conditions this spring falls to 14% in the latest CPC forecast released this week. Here is that forecast, shown as the probability of ENSO phase going forward through three-month seasons. For March-April-May we have an 82% probability of neutral conditions. That forecast is based on multiple model and statistical projections for sea surface temperatures (SSTs) within the ENSO 3.4 regio

Colorado weather: Two storm systems to deliver rain and snow to state during the coming week
There are a couple of storms expected to impact the state through the next seven days, the first arrives this weekend and the second toward mid-week. Let's start with the first. Here it is depicted by the red L over southeastern Colorado midday Sunday. The blue colors you see over the western half of the state represent snow. Within a few hours, the storm is high-tailing it east into Kansas, but we do see some rain (green) and snow on the map for the Front Range and Plains by this point. W

Denver weather: Tracking the chance of snow throughout the day
The chances for snow across Colorado continue today, but for Denver and most metro areas the chance of snow is low as compared to the mountains and the northeastern plains. Light to moderate snow developed in the mountains overnight, some of those showers will pass overhead this morning. Some of the showers this morning could bring at least brief moderate snowfall to your area as they peel off the hills, but not much

Let's prepare for the week ahead in today's State of the Atmosphere by discussing the next weather maker for the state which arrives midweek to bring snow and rain to the region.

For the metro areas, snow chances are likely and accumulations are expected through Monday.

Arctic blast: Dangerous cold remains on track for Denver & Colorado by Thursday
Potentially record setting cold is on tap for the Denver metro area in just a few days. Thursday's existing record low is -25° from 1990, and Friday's is -17° also from 1990. In data through Monday morning, it appears we will rival that Friday record-low temperature. Here's more on the historical perspective of cold temperatures in Denver: It's not uncommon for the city to drop below zero, it happens six times a year on average.

Denver weather: Snow is moving into Colorado, when and where it's forecast to hit
The storm system that we've been discussing for the past week remains on track and will deliver snow to Colorado through Tuesday, but for eastern Colorado the biggest impact remains northeast of Denver and the greater metro area. The data has been, in my opinion, remarkably consistent between updates and has been for nearly a week now. That's odd to me that it hasn't shown any real variations to the track and intensity of the storm. As we've discussed previously, the track is such that the bigg

Although the brunt of the next system will slam the Dakotas and Nebraska with deep snow, Colorado will have its own impacts as we continue to watch for any changes to the storm's path that could dramatically increase the hazards here across the state. As it stands now, the storm will have an impact statewide, the most significant will be largely over the northeastern Plains. Portions of I-70, I-76, I-80, and I-25 will have difficult winter driving conditions, particularly Monday night through T

La Niña update: Weakest SOI in over two years
La Niña is now the weakest it has been in over two years, using the SOI (Southern Oscillation Index) index for monthly values since 1950. The SOI is one measurement tool for calculating the strength of La Niña atmospherically, in this case using sea level pressure values. How does this change the winter outlook, or does it? I discuss that in this video and will present a research image below. Here's the latest monthly SOI data including November to show you the strength relative to all other p
