Monarch Mountain (Base: 10,790', Top: 11,961')
6-day Forecast Discussion Updated for Monday, May 12, 2008...SNOW ADVISORY IN EFFECT FROM MIDNIGHT TONIGHT TO 6 PM MDT TUESDAY...
OVERALL SITUATION TODAY -//> Winds increase on the upper ridges mainly, with increasing cloudiness as another low pressure system approaches from the northwest US (moving through Utah with mountain snow now). Temperatures look mild. Showers (rain/ snow mix for most) and thunderstorms develop after noon as the low pressure system approaches. Snow showers develop this evening and tonight as colder air blows in and clouds lower with the storm, now headed south toward Arizona/ New Mexico.
Tuesday -//> 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 maybe isolated 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 18 to 21--We could see a weak disturbance break up the sunny weather next Tuesday (20th), 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.
