Snowmass - Aspen (Base: 8,104', Top: 12,510')
6-day Forecast Discussion Updated for Wednesday, May 14, 2008OVERALL SITUATION TODAY 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 today, 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 20 to 23--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).
