Weather5280 Insider: Seasonal forecast update, September 2024

It is time to revisit our seasonal weather outlook. First, let's check out what the sea surface temperature anomalies look like. 1) The sea surface temperature anomalies along the equator in the Pacific Ocean continue to cool. This is especially true near the South American coast and westward... This is the developing La Niña. The cooler those sea surface temperature anomalies get, the stronger the La Niña episode. As of right now, we have just started to enter weak La Niña status. However, th

Snow headed to RMNP, rain to parts of Denver metro area
There will be a system sliding through the next couple of days which will increase chances for showers and will drop temperatures a bit. For the mountains, we could see some snowfall on those peaks! First a timeline if you prefer the hourly chart, followed by a statewide animation to walk you through the showers as they hit a few areas the next two days. There will be a couple showers around today, but few and far between. From Wednesday morning through Thursday morning, notice how showers for

Colorado Ski Season start dates fast approaching
Meteorological Fall began on Sunday (September 1st) which mean ski season is headed to the Colorado Rockies! Below is a list of projected start dates: Resorts suggest planning out trips now, rather than later, to ensure lodging/rentals. It's a great way to save too, because prices tend to tick up over the next several months. HOW IS THE SEASON LOOKING? As far as the weather is concerned, our focus has been on the weak La Niña conditions developing off of the west coast of South America. With

Colorado weather: Monsoon flow and some mountain snow possible!
A potent trough over the western US continues to churn this weekend, bringing enhanced monsoonal flow. Generally, moisture will stay in the mountains, but a few storms will attempt to get going along and east of I-25 both Saturday and Sunday. Showers and storms will be mainly driven diurnally, or, with the heating of the day. However, overnight and morning storms in the mountains are likely over the next 36 hours. Moisture will be most prominent in the San Juans as the component of the wind w

Colorado Weather: Cooler with widespread thunderstorms
Quite a few thunderstorms will hit the state today, starting in the mountains and then an increase of storm activity around Denver and on the plains later today. Of the threats, heavy rainfall and isolated flooding is first followed by a hail and wind threat (perhaps a tornado) from the storms on the plains. I'll start with an animation to show where the storms will be, based on some requests, I'll slow this down to make it easier to see each timestep. For the Denver metro area, we could see

After weekend heat, a chance of storms across Eastern Colorado today, some severe
Yesterday, we celebrated our 11th day of 90°F+ heat so far this month. While not as hot as Saturday (98°F), Sunday again topped out in the mid-90s across the region, with only a Trace of precipitation at the airport. The average high for this time of year is 87°F. Today we'll be closer to that average. Most guidance has us topping out in the upper 80s to near 90°F in Denver. It should feel better, generally, than this weekend in particular in areas we manage some storms this afternoon. It's

Weather5280 Insider: Extended outlook as we inch toward the cold season
Time for a comprehensive look at what lies ahead over the next several months. Here is what the sea surface temperature anomalies look like. You can see some "blue" off the west coast of South America. These are sea surface temperatures that are cooler than average. Certainly not La Niña status yet, but still moving slowly in that direction. Why are we only moving slowly toward a La Niña episode? For one, the atmosphere and the ocean have to work in tandem to produce impacts. One piece of atmo

Denver Weather: Flood watch issued again for parts of the city and Front Range
Although I had some rain, even a good clap of thunder with rainfall early this morning, I could use some more - I just don't want too much all at once and that is a risk from today's thunderstorms should you be hit by one. There could also be a higher risk of hail in today's storms. Today's flood risk areas have shifted some since yesterday. If your county is shaded here, your risk is highest. > * WHAT...Flash flooding caused by excessive rainfall is possible. > * WHEN...Through this evening.

Denver Weather: 25-degree drop comes with risk of heavy rainfall and flooding
Today's storms will be scattered, with some at risk of becoming severe, but tomorrow and Friday's storms will be widespread, increasing the risk of flooding as temperatures drop more than 20 degrees in many areas. For today, it'll be a hot one with storm chances shown below. The more likely region for storms to become severe is across the Northeastern Plains. Storm chances increase after today. In a glance, here is the hourly planner for chances for precipitation for Denver. As of now, Friday

Late week cool down for Colorado, storm chances increase; Hurricane Debby makes landfall
As we teased in our last update , a break from the HEAT is on the way this week. Eventually. Not before another couple of days of hot weather, however, and this following Denver's hottest day in years on Sunday with a new record high for the date of 102°F (old record for the date was 98°F set in 2022).

Colorado weather: Hot and mostly dry conditions persist through the weekend; Will there be rain to help with fires next week?
Not much relief from the heat in the immediate forecast as highs will stay in the mid to upper 90s along the urban corridor through the weekend at least. The blend of models shows a forecast high of 100°F in Denver Sunday, which would tie the record for the date (1878). By the latter half of the week more seasonal, less extreme temperatures may finally return – but there's some disagreement in this in the guidance as well. There will be a few isolated storms today along the Front Range, but

Colorado Weather: Fire danger spikes as near-record temperatures return to Denver area
The Alexander Mountain Fire reminds us just how dry and hot this summer has been, and although we hope this fire is quickly extinguished and no new ones ignite, the weather conditions are prime for that type of activity. This week, near-record temperatures will be felt across the region, including Denver, with another potential 100° day on tap for today. So far, temperatures have hit 90+ 34 days (three have hit 100+)  this year in Denver. For perspective, that is the 9th most YTD for any year

Another Colorado heat wave on tap this week
After some rain and cooler temps on Friday and Saturday, we're going to see a return of more summer heat on Sunday—mid-to-upper 90s look aplenty for the Front Range. We'll also have some gusty winds (20-35 mph) out of the west. Some scattered fire danger is also possible. Here are high/low estimates for the next ten days for Denver and Colorado Springs. 10-Day Temp Trend: Denver/Central Park10-Day Temp Trend: Colorado SpringsTemp trends show a signal for heat through most of the week in Denver

Colorado Weather: Smoke-filled air may improve some with late week rain
The air quality is terrible again today, but there is a bit of improvement ahead to end the week. The longer-term concern will be the control of fires in the Northwestern U.S. and Canada and how much smoke improvement we may see in our sky. Let's start with the smoke forecast. I've overlaid fire locations indicated with red triangles. The thickest smoke is in the yellow shades. This animation runs through the next two days. We can see some thinning of that smoke over Colorado's skies into Frid

Denver Weather: Uptick in storms expected today, cooler too, a weekend peek
Below average temperatures for a change today, plus we will see an uptick in storms around the metro area. In terms of chances, there is a definite focus of storminess for Southern Colorado and Plains east of the city. For timing, the metro area has its highest chance of a storm from 1 to 5 pm. Here's a timeline for all of us. Notice how the storms start off few and far between, then merge into bigger "lines" of storms as they move east onto the Plains. The overall risk of severe weather is
