Last week, we talked about how moisture would create showers over the Labor Day weekend, and that some of these showers could drop snow on the peaks over 13,000 feet.

Indeed snow fell on some of the higher peaks.

Here’s Hayden Peak (previously I incorrectly said that this was Castle Peak ... sorry), just south of Aspen:

And below is Pikes Peak, just west of Colorado Springs:

In addition to the snow, the other thing that we were expecting was that the most precipitation would fall over the southeastern half of Colorado.

Again, the forecast models were in the right ballpark. Precipitation on Sunday was heaviest over the southern and south-eastern mountains (red dots denote 1.00 inch of rain).

And the precipitation total for September 1-3 also illustrates that the heaviest precipitation occurred over the southern and southeast mountains.

For the rest of the week, expect afternoon showers every day. We can’t shake the moisture. Like this past holiday weekend, the showers will not make any day a washout, so just be prepared to get a bit wet and avoid the exposed summits during the midday and afternoon to reduce your risk of being struck by lightning.

The moisture will mostly leave Colorado starting on or around Saturday, September 8.

Expect a mostly or completely dry weekend on Saturday and Sunday (September 8-9), and the dry weather could last even longer.

The precipitation forecast for September 9-13 shows a high likelihood of dry weather in Colorado.

And from September 10-15, the temperature in Colorado will be above average while cool temperatures will hang over the northwestern US and western Canada.

Looking further ahead, I do not see any significant cold storms on the horizon. So for now, enjoy the gorgeous fall weather!

Thanks for reading … next update on Wednesday, September 5!
