It's a calm and beautiful start to Thursday, but an approaching system (the first of a few that we have discussed previously ) will bring a risk of damaging thunderstorms and very heavy moisture to parts of the Front Range and Eastern Plains in just a few hours. First, a timeline for the state: That animation will show some isolated storms on the plains this afternoon and early evening ( these have

The wind event continues across the state, particularly the Northern Front Range and the Eastern Plains; wind warnings continue through noon and 6 pm, respectively. As the wind event calms, we focus on cloud cover for Monday's partial eclipse viewing. First, the wind. Here are the Sunday morning observations from the weather service - some of which topped 90 mph!

As we settle down after a busy weekend, know that Monday will be impacted by the weather. Those returning to the metro areas from the mountains will have snow to drive through Monday and that will turn into chances of rain and snow as they move from the foothills into the city. Let's kick off this blog's images with an hourly planner for Denver's temperatures and chances for precipitation. First, notice that temperatures hardly budge on Monday, staying mostly in the lower 40s. Tuesday into Wedn

A potent, and quick-hitting system will arrive later today and deliver a wallop of snowfall to some locations. No, not like the big storm a little over a week ago, but enough to be a pain for drivers on Sunday evening when returning from spring break or kicking off their vacation. This will also leave a mess for some of the commuters Monday morning. Keep an ear tuned in...you may hear some thunder as this rolls through. (Thunder, indicating convection, means we could create some small pockets of

A quick-moving but pretty juiced storm system will swing through the state Sunday and bring many weather conditions to the area as it does. First, a timeline. After another mild day today, look for highs to cool about 10°F on Sunday (or perhaps more, depending on the speed of the cold front) and then to dip considerably Sunday night behind the passage of an arctic front set to move through during the afternoon hours on Sunday. The timeline below for Denver shows pretty good precipitation pro

We've been talking about the early days of February for a couple of weeks now on Weather5280, and for Insiders we had an update on what we're watching for the month yesterday as well. From a forecasting perspective, things certainly look "interesting", while the uncertainty remains quite high as to how things will ultimately pan out. We'll get in the weeds a bit here, and then breakdo

It still looks like a wintry weather pattern over the next 10 days, kicking things off tomorrow with some snow across parts the state, and cooler temperatures for everyone along the Front Range. Here's the latest 10-day temperature outlook for Denver from the ECMWF model: As mentioned, a storm system will impact mainly southern portions of the state with snow on Thursday, another storm system flies through Friday evening, and another is possible Sunday night and Monday – but that one has been

There's a rapid change about to move across Colorado and right through the metro areas Friday. You'll notice wind, a sharp drop in temperatures and many of us will see some snow to add potential icing to roads in time for us to start the weekend. Out of all elements, I think wind and the temperature change will be the takeaway. Snowfall, remains hit and miss for much of the metro areas with this one...but still a threat and a threat to roads before we get the day done Friday. So, when does this

A heat advisory has been issued for parts of Colorado's Front Range Monday. Denver will threaten the record high for this date, which is 102°, but even a hint of a cloud or two may keep temperatures colder than the record. Colorado Springs may also set a record today. What's a heat advisory? Well, heat has reached a level that may be dangerous to many of us. > Per NWS for Monday: Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbo

Wednesday was very active across the eastern half of Colorado, with notable reports of large hail and tornadoes throughout the late day. In total, you can visually see the number of warnings the area was dealing with: A number of injuries were reported from Red Rocks while concert-goers fled a severe thunderstorm. As of this post 90 were injured – 7 of which were severe enough to be hospitalized, from Ping-Pong size hail stones there. > 🚨#BREAKING [https://twitter.com/hashtag/BREAKING?src=ha

Large hail and tornadoes are possible in parts of Colorado today, including the metro areas, and the chance continues into the evening and overnight. We have a dynamic setup with a cold front moving in late today, which will act to combine plenty of warmth and plenty of humidity. Here are the overall chances for storms and locations. Of that area, there are increased risks from damaging thunderstorms as shown here. EDIT (11:00 AM) the following image is new as the threat has increased from wha

Notably cooler today with that cloudy sky and scattered rain around the area. Afternoon showers and thunderstorms become likely here shortly for the Front Range, then lower chances of getting rained on for the weekend. There's a line of rain and snow over the mountains Thursday morning, see how the showers advance in this timeline that goes from today through Sunday. That animation shows the most widespread activity is Thursday, then more scattered and isolated in nature through the weekend, t

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

It's a calm and beautiful start to Thursday, but the Denver area is about to see and feel a very rapid change in just hours as a strong system flies through with wind, sharply dropping temperatures, rain, and snow. Here's the timeline for Denver and Colorado Springs to set the stage. Denver's PlannerColorado Springs' PlannerThat's a pretty quick change as those rain and snow chances increase, but it may be the wind that you'll notice first. Throughout the afternoon wind gusts will pick up and

Fort Collins, out of metro area locations, had four to five inches of snowfall since yesterday. The storm pattern may deliver more snowfall to the metro areas this weekend, but the next heaviest push of snow will come Monday. First, let's look at the snowfall from Fort Collins last night. > SW Fort Collins. Up late tonight and getting rewarded with some moderate to heavy snow. Looks like 3 or 4 inches accumulation as of 1 am. #cowx [https://twitter.com/hashtag/cowx?src=hash&ref_src=twsrc%5Etfw

The fog this morning, as we discussed in yesterday's forecast, focused on the Front Range creating a sheen of ice coating on a lot of cold surfaces. A winter weather advisory had been issued to cover the travel aspect of that threat. The alert runs through 11 am. For the Denver area and Front Range we will see the low clouds and fog thin throughout the day but there may be more on tap tonight, especially around Colorado Springs. Here's an animation to show the thickest fog (black areas) and ho

Although the chances appear lower end, there is the potential for fog to increase over metro areas and plains tonight to lead to areas of icing from freezing drizzle overnight. If we look at the hourly planner for Denver, you'll see low chances of showers appear starting tonight. That is the chance for this freezing drizzle. Here's a way to visualize the fog/low cloud layers. I slapped this animation together to show fog, black areas, increasing and where. For Denver, and others in the metro

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

The vast majority of us picked up some new snow overnight, which now lays on top of existing snowpack and ice from the overnight to make things quite slick in a number of areas. Here are the observed snowfall totals from the past 24 hours through 7am Monday morning: Most areas saw from a dusting to 2" of snow overnight, fitting nicely with our forecast . There were a couple of 3" totals on

We've been discussing this system during the past several days; whether in our Insider post last week or yesterday's public forecast , we have couched this system in terms of concern for just how north the track will be and therefore the impact changes on the Denver metro areas. In data from Saturday afternoon thr

The next system will swing through Sunday night and Monday to bring widespread travel issues across the region. For the metro areas, snow chances are likely and accumulations are expected through Monday. For Denver: For Colorado Springs: As you look over those hourly planners, Colorado Springs stands a higher chance of rain initially before a snow changeover, however, it is pretty early yet to be getting too specific on that timing. When it comes to timing, data through Friday morning indica

Tuesday will be quite warm, 60s, ahead of the next weather machine that is set to drop heavy snow on the mountains. Here is an animation of the system moving through the state today through Thursday morning, note we'll have some rain and rain snow mixing at lower elevations: For metro areas, rain and snow will move in later Wednesday, with the biggest impact on the afternoon and evening roads. The total storm impact from late Tuesday through early Thursday is shown here. Speaking of impacts

Snow for the mountains today, and part of that may slip onto the Palmer Divide this afternoon. Areas in Douglas, Elbert & El Paso Counties have the highest chance to see some, but really anyone along the Front Range can see some snowflakes today with any cloud cover peeling off the mountains. Here's an animation of estimated snow showers through Friday night, but the vast majority of snowfall is happening today and only lingering snow in the mountains for Friday. That little blip of snowfall w

That system we mentioned in this week's State of the Atmosphere is looking like it could pack a bit more of a punch than it appeared a few days ago. This mostly comes in the form of chillier temperatures for Thanksgiving Day, but we could also see blustery conditions and even some snow across the region overnight Wednesday into Thursday morning. You can see the snow scoot through on the GFS, animated below, but you can't blink or you'll miss it! You can track snow dropping out of the northern

Throughout the week, warmer than normal and drier than normal conditions will return to most of us as the pattern across the country is a hot one for the Plains. In Denver, a 'drier' week is on tap. This is not to say we won't have storms around but that the number of storms will decrease. This is "okay" for those in Denver that were near the recent flooding. > Avoid driving in flooded roadways.
