Forecast Confidence
· Snow: Moderate confidence for amounts above 4500 feet.

Falls (1 ½ inches forecast), Lakeview (4 inches forecast), and Alturas (4
inches forecast) due to snow levels forecast near these city elevations.

rise to 4500 to 5500 feet in the afternoon with the highest snow levels in the
Siskiyous and western Siskiyou County. Snow levels will then lower late in the
day and evening to near 4000 feet.
