Rain reports from Tuesday's storm system

06/18/25 8:45am: Morning, rain reports first. Great to see more heavy rain across parts of the northern front-range and eastern plains. Areas near Ft. Collins, Loveland, Greeley towards Ft. Morgan and Sterling picked up 0.50" to 2.0" of rain and also some larger hail in spots.

Den/Bou picked up 0.25" to 0.75" in spots, but it was much more spotty...for example at my house in Westminster only 0.01" (only 0.03" the last 2 days unfortunately).

And also some heavy rain (0.50" to 1.0") near Colorado Springs and also a confirmed tornado near Woodland Park which did some damage to the forest down there (more on that later).

In the mountains very little rain, with just a bit from Summit Co and east across parts of the Front Range mountains (mountains will need the monsoon moisture to get some more rainfall going).

Here are some notable 24hr reports form CoCoRaHS:

Greeley 3.4 SSW: 2.14"
Lyons 8.9 WNW: 1.55"
Limon 8.6 N: 1.55"
Windsor 1.4 WNW: 1.50"
Estes Park 10.5 SE (Pinewood): 1.40"
Fort Collins 2.3 S: 1.28"
Loveland 2.4 NW: 1.21"
Colorado Springs 5.7 WNW: 1.17"
Erie 2.2 W: 1.00"
Broomfield 1.0 NE: 0.45"
Denver 2.7 ENE: 0.33"
Boulder 1.6 NW: 0.30"

Looking ahead, really warming with basically a heat wave from Thu-Sat: high temps near 100 for Den/Bou, 80s for the mountains...but this heat wave won't last long. A cold front is expected to move down the front-range (and into northern CO) on Sun afternoon / evening and that will usher in cooler and more unsettled weather for next week.

I see deeper monsoon like moisture moving back into CO from the south Tue-Thu of next week, so better storm chances in that time-frame, we will look at that more in detail later.
