Colorado Weather
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

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

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

Friday's rain and snow chance, Thursday PM update
We continue to track the chance for rain and snow Friday, especially late in the day, through Saturday. Although the total impact will be hit and miss, some areas will have enough snow to bring some slush and snow to roadways –– albeit a low impact considering so many of us shelter in place. Let's watch the system from Thursday evening through Saturday evening. That L, center of lowest pressure, develops over the eastern plains and then gains strength as it pushes northeast toward Des Moines.
Denver Forecast
Thursday AM update: The chance of snow on the increase this evening, will carry through Friday
We continue to track our next chance of snow across Northeast Colorado in a setup that will prove very difficult to pinpoint where the heaviest totals will ultimately end up. That chance of snow will begin as early as this evening's commute along the Front Range and carry well into the day Friday. The National Weather Service has issued a Winter Weather Advisory for the urban corridor and adjacent plains. It goes into effect at 6 pm this evening and will remain in effect through Friday.

PM Update
Beautiful weekend ahead, cold and a chance of snow return for first week of February
MOS guidance continues to paint highs in Denver in the mid to upper 60s this weekend as ridging moves overhead and quiets our storm track for a couple of days. Latest guidance shows highs around 64°F on Saturday to near 70°F Sunday. We think Denver has a good shot at the 70° mark, but should land a few degrees shy of the record for the date which is 74°F set back in 1934. Highlighted in red below are the GFS high/lows for the next week, with a 69°F currently for Sunday and dropping into the tee

Weekend system to bring some snow to eastern Colorado, colder temperatures
Our quiet weather pattern will give way to a colder and perhaps snowier weekend across Northeast Colorado as we round out 2019. This system has been long broadcast by weather models to move through the region. In the last 24 to 48 hours or so we've seen a bit of a shift in the track –– and with that shift, we see a greater chance for snow across the Northeast Plains than was indicated in our update earlier this week. The greatest confidence of an impactful snow is shaping up to be east of Denv

Heavy snow for the Colorado Rockies this weekend, Winter Storm Watch posted for Colorado Springs
Before we talk about the snow potential for the weekend, we will have some strong wind to deal with on Friday. Wind gusts in the foothills will likely be 50 mph or better. Some of that strong wind will also sweep through Denver and adjacent areas to the east. Temperatures will top out in the 40s and lower 50s, so while it won't be a cold day, the wind with those temperatures will make you want to keep the coat handy. Not a huge amount of change in the modeling today from our update last night [

Monday PM update: A mostly quiet work week, snow returns to the state this weekend
While we've tracked a few bands of snow today peeling off the mountains, the weather has for the most part been quiet east of the hills in recent days. In the mountains, snow has made travel difficult. Below is a look at Berthoud Pass early this afternoon, showing icy and snow packed conditions on the roadways. Snow as mostly come to an end across teh high country this afternoon, but a spotty 1 - 3" will be possible through this evening. Over the next several days the weather turns drier acr

Wednesday PM update: Some rain and snow around by Thursday morning, worst of it stays in the mountains
As promised, quick update this evening on tomorrow's rain and snow chances. Snowfall totals still don't look huge –– temperatures will be borderline for snow, and very few of the models are showing much in the way of accumulation. With timing possibly coinciding with the morning rush, it's worth just keeping an extra eye on the weather tomorrow morning, however, and perhaps giving yourself a little extra time on the way to work just in case you encounter some rain or snow. The timeline for Den

Tuesday PM Update: A chance of rain then snow, accumulation possible Wed evening through Fri morning
We hope you all are enjoying the beautiful weather across the region to start this week, as colder and wetter changes are on the way starting tomorrow. The national map today shows a mild pattern in place across much of the country, with chilly weather hanging on across the Great Lakes and mid-Atlantic: As we discussed in this week's SOTA, our weather starts to change tomorrow as a large cutoff low over the Southwest United States begins pumping moisture into the state in the form of rain and

Tuesday PM update: Is the heaviest snow done?
After an exciting morning, anticipation for the afternoon wave has made for a long wait. As of 3pm we are seeing signs of life again on the radar, with a band up north forming, and more activity picking up south of Denver as well: The trend through the day has been to be weaker and further south with the afternoon/evening snow. This actually will help our forecast, for as you'll recall we went low across the northern urban corridor [/blog/2019/10/28/round-one-snowfall-totals-winter-storm-warn

Monday PM Update: Foothills, Palmer Divide Look to be Favored for Heaviest Snow Midweek
Even as snow continues to fall across the High Country this afternoon, we continue to look ahead to the next blast of wintry weather due to move through Wednesday into Thursday. This next system, unlike the one that moved through the state this weekend, is likely to bring a higher chance of snow for the urban corridor, though plenty of uncertainty as to how much, remains. At 500mb we see a trough drop out of the Northern Rockies along with the northwest flow aloft Wednesday during the day, the

Wednesday PM Update: Showers Possible to End Week and a Quick Check on the Weekend
As discussed in this week's SOTA , warm temperatures across the region today and tomorrow will cool by five to 10 degrees by Friday. Should Thursday hit 80-degrees on your thermometer, it may be the last time this year. The average date of last 80-degree high in October 11th. The rest of October looks cooler than average, and there are only 3 occurrences of 80s in November...so, this may be it for the 80s outside of a record-

Wednesday PM Update: Good Storm Chances Today, Thursday
As discussed in this week's SOTA , today and tomorrow feature better storm chances across the region before again decreasing a bit for the weekend. Today's storm chances will be in the 30 to 40% range for most of Eastern Colorado, increasing to 60 to 70% chances on Thursday –– especially across Northeast and East-Central Colorado. No, not everyone sees storms. But, with any luck at all these increased chances will equate to a f

Monday PM Update: Summer Heat on the Way
Well, after a remarkably cool weekend, which featured plentiful mountain snow and some great rains across the Plains, the weather is about to switch to summer mode as head deeper into the week. First, a look at the last seven days. Precipitation totals from 1 to 4" were common across northern Colorado, with some good totals across the Southeast Plains as well. Coverage was much sparser across Southwest and South-Central Colorado. Tonight temperatures remain below average across a good porti

Tuesday PM Update: Some Snow by Wednesday as Wet, Chilly Week Continues
The going forecast remains track as wet and cool weather will continue to dominate the pattern across the state through much of the remainder of the work week. At our station we picked up 0.1" overnight Monday, with an additional 0.17" so far today. Temperatures have fallen into the 40s in Denver as of early afternoon, which is about where we'll be for highs both Wednesday and Thursday. Additional precipi

Wednesday PM Update: Off and on Heavy Mountain Snow through the Weekend, Unsettled at Times on the Plains
Active weather continues to be the theme for the state as we head into the second half of the week and this weekend. Most of the main activity will be across the high country through the weekend, with heavy snow for much of western Colorado. A look at the GFS shows snowfall through Sunday will be pretty good for the central mountains, as several systems fly across the state in the coming days: Across the plains the next several systems look like they will have minimal impacts. Tonight we may

Weekend Snow Event, Thursday PM Update
The weekend snow event is on track to spread heavy snowfall across many areas, including sections of Denver and potentially near Fort Collins this time too. Skiers/riders will love the weekend trip, heavy snowfall in the mountains Friday and Saturday with well over a foot of new snow on a lot of ski areas. Locally, there are ultimately two waves of energy that will bring snowfall to the area. The first scheduled for late Friday through Saturday morning and this will hit Northern Colorado and S

Thursday PM Update: Rain and Snow Showers For the Plains, Heavy Snow for the Mountains
Models have trended a little wetter this evening and overnight across Eastern Colorado. Still not expecting most areas to see snow, and for those that do any accumulation should be on the low end. Rain, mixed precipitation (perhaps some freezing drizzle!), and some snow across the plains however does look likely starting this evening and carrying into Friday morning. The lates HRRR model shows snowfall totals through 3am really focused across the mountains. For the Northeast Plains we see some

Friday PM Update: Snow Clears Tonight but Could Return Again by Monday
For the second week in a row areas across the region saw a system over-perform. How about that! Of course, our area wasn't one of those areas as our station picked up about 1" of snow today despite some impressive snowfall at times. South and west did best –– where some areas across the Palmer Divide tucked up against the foothills saw as much as 8" (!!). We saw several 3 - 4" reports from Denver's west side, and a couple 2 - 3" reports from Westminster that always seems to do well with these s

Thursday PM Update: Heavy Mountain Snow, Showers for the Plains on Friday
Our next weather maker arrives this afternoon to western Colorado and will eventually bring a chance of rain and show showers to eastern Colorado on Friday as well. Heavy mountain snow will be the main story with this system, as impacts east of the mountains look limited. For totals over the next 72 hours I like this map. Big question might be is if we see a snow burst Friday afternoon/evening deliver localized greater snow totals around the greater Denver area or not. As you can see, great

Wednesday PM Update: Warming Trend to End The Week
Well, not a blockbuster, but nice snow and a good ol' fashioned arctic chill to go along with it. We picked up 2.3" of snow at our station in Denver with a forecast of 2 - 5". Verified, but just barely. Snow totals across the region ranged from 1 - 4", with no real "boom" totals coming in. We knew it'd be hard for this setup to over-perform, but we did have hopes it would do a bit better in spots. Denver International Airport picked up

Wednesday PM Update: A Chilly and Unsettled End of Week and Weekend
We're continuing to track changes to our weather as we end the week and head into the weekend. Today's mild weather will slowly be replaced by colder air and precipitation chances across the state. The mountains stand to see the best snowfall over the coming days, with a slightly more complex forecast ahead for the urban corridor and eastern plains. Taking a look at the GEFS (GFS ens
