05/19/26 8:30am: Well that was impressive precip event for the northern front-range. Happy the forecast panned out mostly as expected. And its still chilly and socked in along the front-range this morning.

I have had a light rain/snow mix at my house in Westminster this morning with a temp of 37 (was 34 at 7am). I measured 0.78" of rain in the last 2 days, and thats on the low end of the range for this event. More importantly, over 2" of liquid in the last 8 days!

Areas from Boulder to Longmont/Lyons, Ft.Collins/Loveland areas picked up 1.25" to 2.25" of rain. Much of Den/Bou picked up 0.50" to 1.25" of rain. With 3-8" of snow for the foothills and more in the mountains.

Here are some notable 48hr rain (and snow) reports from CoCoRaHS:

In the mountains great to see 8-12" across the northern front-range mountains with 4-8" for the rest of the north-central mountains / I-70 mountain corridor (pretty much as forecast).

The one area that did basically bust was areas near Silverthorne, Vail and Beaver Creek with little rain/snow there but at least some (too much east to west upslope flow).

Here are some notable snow totals from SNOTEL (via CAIC) and the ski areas snow-stake cams:

Roach snotel (Rawah): 12.0”

Never Summer snotel (RMNP): 11.0”

Niwot snotel (IPW): 10.0”

Cameron Pass snotel 9.9”

Arapahoe Ridge snotel (IPW): 9.0”

Telluride snotel 4.2”

Copper ski area 4.0”

Snowmass ski area 3.0”

Looking ahead:

We have much more on the way: Actually 3 more storm systems really:

Short-wave for this afternoon with more rain/snow 12pm-8pm

Another one for tomorrow (Wed), more rain/thunderstorms: 1pm-9pm

Then another stronger storm system coming in from the northwest will impact the state from about 12pm Thu to 12pm Fri: more accumulating snow for the north-central mountains, more rain for Den/Bou and the front-range.

It won't really dry out until Saturday. I'll have more details on this soon (likely this evening). Loving this!

How are conditions in your neck of the woods this morning? How much rain or snow did you get?
