October snow forecast; Fall color update

Tomer’s Take: Two active periods for mountain snow are possible regulated by a ridge of high pressure. Two active periods slightly favor Western Slope zones for higher totals. Best accumulation will occur at higher elevations with melting in-between. Peak Fall color in Colorado is running behind schedule in some mountain zones. My full Winter Forecast […]
