Keystone Resort Discussion

Updated Wednesday April 24, 2019 at 1:00am PST

YESTERDAY: "warmer, with afternoon and evening thunderstorms developing in the area, especially/ mainly over the peaks, mostly isolated in nature, but scattered over the upper mountain areas after a sunny morning"

TODAY and Thursday look warmer, with afternoon and evening thunderstorms developing in the area, especially/ mainly over the peaks, mostly isolated in nature, but scattered over the upper mountain areas after a sunny morning, all across western Colorado. An upper-level weather disturbance passes through today, triggering some extra thunderstorms. This is as high pressure ridging builds in overhead. Less thunderstorms are expected on a warmer Thursday.

Friday and Saturday (26-27th of April) I expect low pressure to move by to the north, with west winds and drier air moving in, gusty winds and mild weather, with less chance for thunderstorms.

Sunday and Monday (28-29th of April) low pressure to the north exits on a warmer Sunday with less wind, then clouds increase on Monday as low pressure moves in toward the area, showers possible then, possibly some snow on the mountain, and more next Tuesday (30th April, last day of April). CM

LONG RANGE: More storms move in for next week (early May), with winds and some showers, some snow, mostly above 9,000 feet. May is expected to be more unsettled than usual, with more snow and colder weather overall. CM

Where to be this weekend... April 5-7...

A few storms move into the Pacific Northwest down through Tahoe, and across Utah and Colorado, affecting Sun Valley, Big Sky, and Jackson Hole as well, delivering snow, but with some snow level issues...

By Friday afternoon...


High pressure ridging will be building in across the west coast as we move toward Saturday and Sunday, but first, we have 2 storms, today and another on Friday, hit Tahoe with a few inches to 1/2 foot of snow this afternoon through tonight, then on Friday a stronger system moves through with 1/2 to 1 foot of snow. Show up on Saturday for a warmer and spring conditions kind of day in Tahoe! Snow levels will be above 6,000 feet, near 7,000 feet at times for Tahoe.

Utah and Colorado will then see some snow Friday and Saturday, and the higher elevations mean less snow level issues. Light to moderate snow totals are expected, with some powder days possible Saturday for Jackson Hole and Big Sky as Sun Valley to Jackson Hole and Big Sky resorts will see snow now and through Saturday. Saturday's storm system may generate some Sunday powder days across northern Utah and Colorado. Southwest slopes are favored... Go get it!

We are giving away 2 Aspen-Snowmass lift tickets for use next weekend or the following one (19th-21st)! There will be a lot of "end of season" stuff going on... Be sure to follow us on Instagram for a shot and the announcement! CM
