    Following a brief period of dry weather, more storms will barrel into the northwestern United States through this week.

    November is the wettest month on average in the main population centers across the Pacific Northwest, according to AccuWeather Meteorologist Max Vido.

    “This is primarily driven by a more active jet stream across the North Pacific Ocean, bringing frequent storms to the region,” he said.

    The jet stream is a high-speed river of air at the level where jets cruise.

    “We will see a pattern setting up into this week with several waves of storms expected to unleash rain, wind and mountain snow across the Pacific Northwest,” Vido said.

    “Into Monday, the first of several storms this week will move onshore, supporting persistent rain and gusty coastal winds,” Vido said.

    Wet and windy weather is expected to overspread the region. On-and-off showers will plague the San Francisco Bay Area, while precipitation inches through Idaho and western Montana.

    “[This] will coincide with lowering snow levels throughout the region as plowable snow falls throughout the Cascades and Bitterroot Mountains,” Vido said.

    Snow levels will fall to pass level, making travel difficult at times.

    “Some snow could even fall as far south as the northern Sierras in California.”

    Gusty winds at the coast could even lead to some tree damage and sporadic power outages.

    Even as this particular system moves inland and weakens through Tuesday, the next barrage will not be far behind.

    “Through the end of the week, rounds of rain and snow will lead to poor travel conditions and delays,” Vido said.

    Some of the rain and snow could reach central and Southern California late in the week.
