LONG TERM...Tuesday through Saturday

Tuesday will be dry and clear with temperatures about 10 degrees above normal. The upper level ridge responsible will quickly move east by Tuesday night. Clouds increase ahead of an approaching trough and cold front. The frontal passage reduces snow levels to 3500-4500 ft MSL by Thursday morning, with widespread precipitation expected late Wednesday morning through the evening. Scattered precipitation continues Wednesday night through Thursday as the moist northwesterly flow behind the frontal remains unsettled. Building high pressure in the north Pacific steadily decreases precipitation chances each day.
