An unusual weather pattern that knocked out power to more than a 1,000 customers in Yakima is expected to bring anywhere from 2 to 10 inches of new snow in the Cascades by Thursday.
Warm winds on Monday night kept Pacific Power crews busy repairing power lines downed by blown tree branches in 20 different places, said Pacific Power spokesman Tom Gauntt in Portland.
Service was knocked out to more than 730 customers in the area around Nob Hill Boulevard and 10th Street alone. For most customers, power was restored by about 11 p.m. — about four hours after it was first lost. But some customers went without power until about 12:30 a.m., he said.
Winds of 35 mph, with gusts up to 50 mph, kicked up about 3:30 p.m. Monday, while temperatures rose from the lower 30s to the upper 50s during that time, according to the National Weather Service in Pendleton, Ore.
Temperatures remained relatively warm on Tuesday, with highs in the lower 40s, the weather service said. But the warming trend is expected to end tonight. Temperatures today are expected to reach the mid-40s before dipping to anywhere between 18 and 27 degrees, the National Weather Service said.
Temperatures are expected to remain colder through the weekend, with highs in the low 30s and overnight lows in the mid-20s, the weather service said.
As overnight temperatures drop, more snow is expected above 4,000 feet in the Cascades, with anywhere from 2 to 10 inches tonight, and possibly the same amount overnight Thursday, the weather service said.
Roughly 3 inches fell on the mountains during the day Tuesday, prompting highway officials to close Snoqualmie Pass to traffic twice while crews worked to reduce the avalanche danger. There is a slight chance that some snow may fall on the mountains through the weekend, but nothing significant, the weather service said.
But the Yakima Valley floor is expected to remain mostly dry. The short warmup period did not prompt any flood warnings in the area, the weather service said.
