Keystone Resort (Base: 9,280', Top: 12,408')
6-day Forecast Discussion Updated for Tuesday, May 13, 2008OVERALL SITUATION TODAY -//> Colder and cloudy with scattered snow showers as low pressure drops through, though most energy passes to the west through Eastern Utah mainly (then into AZ/ NM). Light additional snowfall is expected. Clouds and snow clear out late day/ evening.
Wednesday through Friday -//> Low pressure scoots out and we are pinned between an extremely strong and large summer-like high pressure ridge over California/ Nevada, and strong low pressure centered over the Northern Great lakes/ Ontario Canada. This spells northwest winds and below average temperatures for Colorado, with some clouds and light snow showers later Wednesday, all Thursday, and early Friday (then clearing out).
Saturday and Sunday -//> Strong high pressure ridging moves overhead, with sunny skies and warm temperatures expected. CM

Long range forecast / discussion...May 19 to 22--We could see a weak disturbance break up the sunny weather next Tuesday / Wednesday, otherwise sunny and warm weather continues through the following Saturday (24th) under strong high pressure ridging aloft. As more low pressure (weaker) affects the Northwest US (around the 24th/ 25th), the orientation of the wind flow aloft may allow some subtropical moisture to feed up from the south for daily thunderstorms in late May (27th onward possibly).
