A stream of Pacific moisture will lead to widespread rain and snow showers from Northern California to Washington early next week.
The wet weather will not be nearly as significant when compared to the largest storms this past winter. Still, enough rain and snow could fall to cause delays on the road and disruptions to air travel.
The weak nature of the storms will limit the threat for flooding and damaging winds.
The first push of moisture will arrive on Sunday afternoon into Sunday night across Northern California and Oregon.
“Locations hit by the most persistent rain in the foothills of Northern California may have upwards of one half to 1 inch of rain by the time the system exits on Sunday night,” AccuWeather Meteorologist Kyle Elliott said.
Slippery travel could ensue over I-80’s Donner Pass as snow intensifies into Sunday night.
A roughly 18- to 24-hour dry break is anticipated before the next storm rolls ashore and targets a broader area beginning on Monday afternoon and continuing into Tuesday.
“Portions of Washington state which will be spared from the first storm will be hit by this storm,” Elliott said.
Rain will reach the I-5 corridor from Redding, California, to Portland, Oregon, and Seattle by the Monday evening commute.
Major League Baseball fans headed to the Houston Astros versus the Oakland Athletics game in Oakland, California, may need to bring a poncho or umbrella to the Monday night matchup.
“The heaviest precipitation will be confined to coastal regions of Washington and Oregon, where up to an inch of rain can fall by Tuesday morning,” Elliott said.
Rain will fail to make it any farther south than Santa Barbara, California.
Los Angeles and San Diego may only have a slight increase in cloud cover.
“The highest elevations of the Sierra, already hit with phenomenal amounts of snow this winter, are in line for another 6 to 12 inches of snow into Tuesday,” Elliott said.
Wintry weather and slick travel will also occur over the highest elevations of the Washington and Oregon Cascades, where a few inches of snow may fall.
The wet weather will fall over areas that are well above normal in terms of precipitation so far this year.
The cities of Redding, Portland and Seattle have received nearly 10 inches of rain more than normal from Jan. 1 to April 14.
