Foot of snow in Colorado; Monsoon-esque Flow 5/14-5/15

Tomer’s Take: A foot of snow has fallen above 10,000ft in parts of Colorado including Arapahoe Basin and Loveland Ski Area. 4-day rain totals in Denver now exceed four inches! What’s next? This storm system exits Colorado but a new push of moisture is likely 5/14-5/15. It resembles a Monsoon flow normally seen in July-August.

Arapahoe Basin, CO is reporting 13 inches of new snow in the last 48.

Loveland Ski Area is coated in 10-12 inches of new snow.

    We measured 6.18” here at our house this week. Thankfully having that spread out over a couple of days prevented flooding
