It’s looking a lot like spring in Snohomish County — at least on Tuesday

EVERETT — It’s that time of the year when the Pacific Northwest weather can’t quite seem to make up its mind.

On Monday, another atmospheric river finally tapered off after a wet weekend. The Snohomish River reached peak flows around 5:30 a.m., with heights reaching nearly 13 feet in Monroe, 15 feet in Gold Bar and over 24 feet in Snohomish. The heightened flows reached “action stage,” where the National Weather Service urges preparation for possible flooding.

In the northern part of the county, the Stillaguamish River near Arlington also reached flood action watch on Monday morning, peaking at 13 feet.

“There’s a lot of water still working its way out that we’re keeping an eye on today,” Kirby Cook, a National Weather Service meteorologist, said Monday morning.

But Tuesday could see the first 67-degree day in the Everett area. Warm air will reach the area Monday night, helping to push the last bit of rain clouds north, Cook said.

Expect a 20% chance of rain before 11 a.m. Tuesday, but then skies should begin to clear, forecasters said.

The clear skies won’t last for long, though. Thunderstorms, mixed with a little bit of everything, are possible throughout Wednesday.

“Certainly, we can see heavy rain with persistent or strong thunderstorms, gusty winds, even lightning,” Cook said. “Beyond that, it looks like maybe a little bit of wind or some spots on Thursday and Friday, breezy winds, and then back to mountain snow late in the week.”

Forecasters predict Stevens Pass will receive a little snow this week, with 1-2 inches on Friday if it doesn’t reach the high of 36 degrees.

In Everett, expect warm and maybe wet weather with chances of rain both days. Right now, Saturday’s high could hit near 54 degrees and Sunday could be slightly warmer with a high of 57.
