Short Range Forecast Discussion - Updated for Monday, June 01, 2015
Large-scale low pressure sits across the northwest US today through Thursday, with an increase in afternoon thunderstorms and showers today thanks to some upper-level instability and increased moisture across the area, then mostly sunny, dry and warmer conditions develop under a southwest wind flow aloft across Colorado Tuesday through Thursday. We see another increase in mainly afternoon thunderstorms and showers again Friday and Saturday, with temperatures dropping a bit, as subtropical moisture is drawn up from the southwest due to a tropical system moving (unusually) north into southern California, and combining with a northern low (weak) offshore of CA. It looks like most of next week we could see above average levels of afternoon showers and thunderstorms, and a mix of clouds and sun, with near to below average temperatures. CM

7 day to 2 week+ forecast (since 1998) - We plan to bring this back in the fall, unless we receive interest in firing the longer range forecast back up, sooner.
It looks like a strong El Nino may be in effect this fall and winter. This would usually cause heavier rain and snow across California and the southwest US. We will be monitoring the progress of this right here, stay tuned... CM
Keystone is home to three magnificent mountain playgrounds—Dercum Mountain, North Peak, and The Outback. There’s something special for every skier and rider of any level at each mountain. There are more than 3,000 vertical feet and over 3,000 acres of bumps and bowls, glades and steeps, groomers and rollers to be experienced.
