Potential pattern change around Oct 12-13, hot before that
10/04/26 11:20am: Morning, happy Sunday, Go Broncos! It may be hot and dry now but I do see some weather changes on the horizon. Likely going to get more active and cooler with a storm system around Oct 12th-13th (a week from Monday) and that system could bring some snow the mountains and cooler temps across much of the state.
In the meantime quite hot unfortunately. It looks for tomorrow (Monday) and Tuesday near record high temps for Denver/Boulder with forecast highs around 86-88. And even beyond that it will continue to be in the 80s through Sat (for 1 whole week).
Even going to be in the low 70s in the mountain valleys (for examples highs of 70-73 for Silverthorne today through Tue (upper 60s the rest of the week), slight chance for some showers on Wed.
Here are the previous record high temps for Denver (at the airport) and the year they occured
Oct 5 87° 2024
Oct 6 87° 2020
Oct 7 87° 1934
Oct 8 85° 2020
Oct 9 87° 1910
Anyway, really hoping for a stormier pattern initially around Oct 12/13th.
Then maybe another cold-front around Oct 17th/18th
Generally looks more active for the later part of Oct into Nov, fingers crossed.
But per El Nino, in between storm systems we will be dealing with warm temps at times (and near record highs). El Nino brings the warm air at times (think how warm the Pacific Ocean is off the coast of CA towards the equator right now).
Anyway, that is all for now. All you can do is enjoy this glorious sunny weather. I want snow, but at least do have nasty facets forming in the mountains (from early snow sitting on north facing peaks).
First image loop shows the evolution of the weather pattern via forecast 500mb temps (we want to see the darker blues). Image 2 shows forecast high temps for Denver for the next 15 days from GFS. Third image shows forecast: Max/Min 6Hr 2M Temp. + QPF + Snow for Berthoud Pass...you can see some snow and much colder temps around Oct 12th/13th initially, it will change some.
Lastly Go Broncos! Big game against the 49ers today! Hot in SF as well today!
