A rather strong storm will move into our region this evening with a good supply of moisture from the tropics. This will cause widespread rain and snow across the region through the evening before gradually decreasing in strength and coverage into the morning. Snow levels will be remain around 2,000′ and it’s possible snow levels drop during periods of heavier precipitation. The higher elevations and areas east of the Cascades will see high winds through this storm and into Monday. Snow will certainly impact roads and with the stronger winds blowing and drifting snow as well as reduced visibilities will be the concern overnight on the roads. Travel is not advised in the mountain passes through the evening.
Areas above 2,000′ west of the Cascades should expect anywhere from 1”-4” of snow by Monday morning. The accumulation amount depends on the exact snow level of the location. The Basin could see 2”-5” with higher amounts being near the Chemult area and higher elevations. Both the Cascades and Siskiyous could see as much as 8”-10” through the morning, with lower totals around 4”. The mountain passes are going to be problematic in the morning and drivers will need to travel with caution. Be prepared for snow packed and icy roads. Breezy conditions are also going to stick around through the day tomorrow, as well as the chance for snow showers in the higher elevations also.
The tropic moisture feed will continue to filter into the Pacific Northwest, bringing another system southward Monday afternoon and evening. This light and scattered rain and snow showers will continue across the region. The Rogue Valley should be mainly rain by Tuesday morning. All areas should dry out by late Tuesday. Mostly cloudy skies will hang around into Wednesday with several disturbances passing to our North, but high pressure builds in for Thursday and into the weekend.
