Winter will make itself known across Colorado this weekend! Several cold fronts, plenty of arctic cold, lots of mountain snow and a shot at some Front Range snow as well. Winter lovers, this is your kind of weather coming up. The 5-day temperature anomaly shows us that this is cold isn't just going to be a quick in-and-out type of event. It's likely that parts of eastern Colorado see 3 consecutive days of near and below zero wind chills – potentially dangerous stuff if exposed too long. A W

Warming temperatures expected across the state, with Denver to hit the 70s the next several days, but you may see a thundershower depending on where you'll be. Today will be a slight bit cooler than we have been, and muddy on many of our trails before they start to improve this weekend. Or, in greater detail, here are hourly and daily conditions for a few cities. Denver: Colorado Springs: Fort Collins: So, a pretty decent weekend for the outdoors! Looking ahead, there are daily chances for

As discussed in our last post , there will be a need to upgrade the Winter Storm Watch, at that time, into Warnings and Advisories and that's just what happened today. Below is a look at the latest alerts from the NWS for our area, quite a busy map: For perspective, take a look at the alerts across the entire region (below) with a significant portion of the CONUS under winter weather highlig

How'd you sleep through some of that wind last night? It was howling in a lot of areas, and the wind will continue for many of us today through Tuesday as the next system develops and moves into the region. Peak wind gusts since midnight, a few spots hit 70+mph gusts in the foothills near Boulder and Golden: Here are Weather5280, we hit 65 mph at 5:50 am, on our Kestrel 5000. You can view tons of weather stations on ambientweather.net . As mentioned, that wind wil

Here we go again... Snow is set to return to the Front Range today and tonight, and bring several inches of snow to many of us across the region before departing Thursday. The snow will be heavy at times, with travel impacts likely Wednesday PM through Thursday AM. The National Weather Service in Boulder has issued a Winter Storm Warning for cities from Castle Rock, to Denver, up through Boulder and Fort Collins. The Warning goes into effect at 2 pm this afternoon, and extends through 5am Thur

The upslope machine is getting warmed up this morning, and all indications are it'll be running on all cylinders by this evening and into the day Wednesday. All of eastern Colorado will see snow, as well as sharply colder temperatures, but the greatest totals are expected in and along the Front Range foothills where upslope will be king. As you move along and east of I-25 totals will be lower, but the impacts the same – prepare for winter driving conditions from this afternoon through Wednesda

We were bullish in yesterday's snowfall forecast . How that idea holds up remains to be seen, but it's likely that some areas will bust, with the Denver metro area being at the greatest risk for that today, and higher confidence in snow the farther north you go. Confidence This is a generally a low confidence forecast. Not only do we have considerable disagreement in the modeling to how much moisture we'll have to work

The chance for rainfall increases into Friday and lingers into the weekend, with widespread thunderstorms expected along the Front Range and Northeast Colorado. So far, June has been quite a dry month, with only isolated pockets of above average precipitation through the 22nd across Colorado: The moisture received this week, mostly in that cooldown Sunday and Monday, was about the only notable widespread rainfall since May. Precipitation totals this week, through Wednesday: Another benefit

Happy Father's Day! It'll be cooling off today and tomorrow with some scattered rain chances, too. For today, Colorado will be impacted by the first to two cold fronts. The coolest change will be across northern Colorado, and that's where - potentially - we will see the strongest thunderstorms too. More on that in a moment. The second cold front will be pushing into northeastern Colorado Monday. Let's look at temperatures across Colorado for Sunday and Monday. For Denver, we have gone from

For the first time since last September, we may record 100 degrees early this week. As discussed in Sunday's SOTA, hot weather sticks around a few days this week with records to fall across the area and across the Western US. The State of the Atmosphere: Sunday, June 13th, 2021Temperatures will be near to and will set records this week - prepare for a hot one! The hottest temperature so far this year has been 95 in Denver, 94 in Fort Collins, 98 in Greeley, 91 in Boulder, 87 in Castle Rock, an

Temperatures will cool down Friday to offer a brief relief from the near-record setting temperatures felt the past few days. For Denver, temperatures Saturday through Tuesday were in the 90s and neared record territory, Wednesday stopped at 89 degrees, but then Thursday was the hottest of the year thus far with 95 degrees. A southeasterly wind and some clouds likely prevented Denver from hitting the triple digits and setting a record. However, record temperatures are possible next week followi

After some quiet, almost silent, weather days we will see an increase in thunderstorm chances for the weekend. Let's run through a couple hourly planners. One for Denver and the second for Colorado Springs. You can customize your locations for these with your membership. DenverColorado SpringsWe can see the Springs has a higher chance of storms, but in both cases we see Sunday is more likely for some rain. Let's watch an animation across Colorado to show

We're now day of, and models continue to differ on how the next 24 hours or so will pan out across Northeast Colorado. Details around snow totals aside, expect rain and snow showers to increase through the afternoon across northeast Colorado, with locally heavy rain and snow possible through the evening. The HRRR model, which has done quite well with snow events in recent weeks, has trended snowier this morning after keeping the heaviest snow well north of the Denver area in overnight runs. It

We continue to work to piece together how the remainder of the week will pan out, with models continuing to diverge on when and just how much snow we might see at lower elevations. Through Wednesday there's reasonable agreement that indicates the foothills and Front Range mountains could see several inches of snow but in all likelihood we won't see too much accumulate along the I-25 urban corridor. We will chat more on snow in a moment. First, temperatures are chilly across the region today.

First, thank you! We have the best, most thoughtful, and engaged readers in the region. All of your comments last night meant the world, and we are happy to report it's much harder to hear all the internet trolls this morning through all this snow! ❄️💨 While some areas haven't made it to forecast verification just yet, others have hit the low-end forecast and some, with still many hours of snow ahead today and into tonight.

A lot to get to this morning, but let's start with answering the question many of you have been asking this morning: Where's the snow?! It's coming. Our system is now centered over Southwest Utah/Northern Arizona, and will continue its slow trek east today and tonight. As it does, severe storms, rain, and ultimately heavy snow will fill in across the Plains and Central Rockies. We warned everyone yesterday [https://www.weather5280.com/2021/03/12/latest-snowfall-forecast-probabilities-and-d

What a week of weather data watching it's been. Plenty of anticipation tonight ahead of what will likely be a significant snowstorm across north-central and northeast Colorado this weekend. To all of our new readers that have joined us this week, please consider subscribing to Weather5280 to continue receiving weather updates and geeking out with us on weather long after the last flake flies with this storm. We haven't seen much change in the data thi

Well, we've made it to Friday. The incoming winter storm that has captured our attention all week has come ashore across the Southwest United States, and will slowly move up through the Four Corners and across Southern Colorado this weekend. As it does, it will draw ample moisture out of the Gulf of Mexico and throw it, if you will, up against the northern Rockies of Colorado and Southeast Wyoming, delivering plentiful heavy, wet snow to many folks across the region this weekend. The slow mov

We continue to track a potentially significant snowfall event on the way for north-central and northeast Colorado this weekend. While widespread totals in excess of one foot of snow are possible, if even likely this weekend, there remain some caveats to that depending on exact storm track, which this morning remains in question. As for timing, look for rain and show showers to continue off and on through Friday evening. These aren't expected to amount to much, but enough to feel unsettled at t

Data is in from the overnight and morning and shows little change to our continued focus on a significant snowfall event this weekend for Northern Colorado (especially the foothills), Eastern Wyoming, and Nebraska. Let us take a moment to make one thing clear, we are focused on the weekend event in this post but there are snow and rain chances before we even get to the main storm; rain/snow chances increase now through Friday. If need be this will be addressed in a post later Wednesday that wil

We've been stressing the cold, and for good reason. The next five to seven days will be a remarkable stretch of cold, not only for much of Colorado, but for much of the United States on the whole. Here are the latest seven day temperature anomalies forecast by the European ensemble model, showing extreme cold from the front range of the Rockies to the Great Lakes and the Gulf. The worst of the cold will likely be east of the urban corridor, but that's not to say we won't see some extremely c

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

Our must trusted models have backed off snowfall potential this evening for Northeast Colorado, even as many of the high-resolution models continue to show pockets of "boom" snowfall totals across the urban corridor. Look: Denver's Top Five March Snowstorms The NAM has consistently shown the potential for some banded snowfall this evening. We continue to think it's likely overdone on that potential... but should t

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
