Western colorado

Hard to dins weather predictions for Western Slope CO, especially interested in snow predictions for ski season beginning mid-Dec, 2018. Guests who come bi-annually arrive after Christmas - snow for skiing 2016-17 was pitiful.

Weather in October

I would like to know what the prediction is as well for the 2nd week in October here in Northern Colorado. It seems that the temperature has dropped rather rapidly here lately. What are we to expect. I feel like we are going to have an early fall.

Weather for October 20,2018

We are getting married this weekend and would like to know the weather forecast.

Pikes Peak the last week of June

So we would like to hike Pikes Peak the last week of June. Any pros or cons weather wise? Looks like precipitation should be ok - how about temperatures and snow in the mountain?

Weather on Pikes Peak

Start your hike early try to make it to the summit no later than mid afternoon. If you're coming from lower altitude it will be a tough hike. It can take up to 6 - 8 hours. Getting caught in a thunderstorm is a possibility as the afternoon goes on. Parking is at a premium at the base of the incline.

Pikes Peak

Well don't hike on Sunday - June 24th, the Hill Climb is on that day and there are thousands of people there! Go later in the week and it will be cleared out.
