A Stormy Trend Is Expected To Bring Additional Rain and Mountain Snow to the Northwest

Following a storm that swept across the Northwest on Saturday and Sunday, a second, larger storm is predicted to hit the region to begin a new week through Tuesday, delivering flooding rains, gusty winds, and mountain snow.

On Saturday, about 0.25 inches of rain fell in Medford, Oregon, as the first of two thunderstorms brought rainfall to the northwest United States.

This is far above February's rainfall amount of barely 0.08 inches, considering the monthly normal of about 2 inches, as per Fox 13.

After a brief respite, the area will be hit with a significant atmospheric stream late Sunday into Monday night.

Multiple inches of rain are forecast, raising the risk of river flooding through the middle of the next week.

As much as 3 to 6 inches of rain is expected from Saturday night to Monday night, the Skokomish River, which is the most receptive, will most certainly exceed the flood threshold.

According to the National Weather Service, snow levels in western Washington are expected to vary from 4,000 to 6,000 feet from north to south.

The busy and wet weather will continue for much of next week, with short bursts of rain and mountain snow moving throughout the region.

Seasonable temperatures will prevail, with highs in the lower 50s and lows in the lower 40s.

According to AccuWeather Senior Meteorologist Matt Rinde, the majority of the jet stream energy will remain in Canada for the majority of the week, but there will be some dips into the Northwest United States, including rain and mountain snow on Sunday, with a second round expected through Tuesday.

This second phase is expected to linger through Tuesday night, causing delayed traffic and transport interruptions in numerous areas, notably mountain routes.

The National Weather Service (NWS) issued a hydrologic outlook for sections of western Washington on Sunday, forecasting rising rivers, and the Skokomish River near Potlatch is expected to reach moderate flooding status on Tuesday with a rise of more than 16 feet.

Winter weather will come on weekends

Winter weather is on the way to the Cascades, with snow buildup and severe winds forecast above 3,000 feet.

On Sunday, the NWS posted winter weather cautions for the mountain range, warning motorists that significant hourly snowfall rates might make driving difficult to impossible.

On Sunday, a few strong wind warnings and wind advisories were issued for regions of California, Oregon, Nevada, and Washington.

As the storm moves away from the West Coast, it will drop snow in the northern Rocky Mountains on Wednesday before exiting the Rockies and moving across the Great Plains on Thursday, according to AccuWeather Senior Meteorologist Michael LeSeney, who added that snow will fall in the Colorado Rockies on Thursday and Thursday night.

This dynamic trend will direct the heavier rain toward Washington, with Oregon receiving mostly showers on Thursday, although experts expect showers or even dry air for most locations by the end of the day Friday.

Unfortunately for the rain-soaked, long-range experts predict a further substantial storm with plenty of precipitation and colder air to come this weekend.

Snow levels are expected to fall below pass levels, impeding transport once more, and avalanche hazards will likely be moderate in the Cascades.

A flooding rain will also be a danger in coastal regions. This dynamic pattern, on the other hand, has advantages.
