09/26/26 9:40am: Some big time rain over parts of Denver yesterday! Much more hit or miss further north. I hope you are not sick of these daily rain reports, because its a sign of how active the weather pattern is! I know not everyone has picked up substantial rain, but that is how it goes.

Parts of Arvada, Denver and Aurora and out towards DIA picked 0.80" to 1.60" of rain. And parts of southwest CO, closer to Pagosa Springs also picked up an additional 1.00" to 1.50" of rain (really staking up down there).

I saw this from Meteorologist Chris Bianchi this morning: With the 1.10" measured out at DIA it was officially Denver's rainest day in over 1 year (since 09/23/25).

And with the 0.92" that fell on the 18th/19th (plus more rain on other days), Denver (at the airport) has officially picked up 2.22" of rain for the month so far. I know its out at the airport and doesn't represent all of Denver, but that is great total!

At my house I got the split, only 0.04" yesterday but still for the month well over 1" of rain.

Anyway below I show 24hr observed rainfall from MRMS (first image is statewide view, second image is zoomed into the Denver area). Third image shows 24hr rainfall reports from CoCoRaHS (a map snippet over Den/Bou) and fourth image shows top reports across the state.

Looking ahead: Sunny and beautiful across most of the state today with seasonal temps. I'm actually sitting outside right now in Westminster and its glorious!

For tomorrow (Sun) moisture starts to increase, more cloud-cover across the state especially in the afternoon. Some isolated, rain showers across the mountains 2pm-10pm, won't be much.

Then deeper moisture and rain (snow above 12k initially) moves back into southwest CO / San Juans by Sun night into Mon.

It will be rainy over parts of southern / southwest CO on Monday (but mostly in parts of the Elks to San Juans), on/off showers.

Some rain showers over north-central CO (mountains) and the front-range on Mon as well but will be much lighter. Best chances will come later in the day, after 5pm Mon.

Then more rain from Tue-Thu but all the details need to be worked out (see my post from last night)
