Kids in Western Washington are accustomed to bundling up like mountaineers before they head outside to search for Easter eggs. This year, they can leave the parkas and gloves at home.

An interlude of warm, sunny weather that started Friday will continue into the middle of next week, with highs of 70 degrees possible in some areas Sunday.

“It’s going to be nice, believe it or not,” said meteorologist Art Gaebel, of the National Weather Service. “And it looks like it will be midweek before we start picking up some showers.”

That’s welcome news for Alice Ware, who’s coordinating Saturday’s egg hunt at Delridge Community Center in West Seattle. “It’s just a mess when you have to hide the eggs in the mud,” she said.

Attendance is always lower when the weather is foul, said Ware, who recalls several years so miserable the children gave up and went home before anyone found the golden egg.

According to more than a century’s worth of data from the National Weather Service, the odds are about even that the last weekend of March will be wet in the Puget Sound area.

But sunshine is by no means unprecedented. The record high for March 30 at Seattle-Tacoma International Airport was 72, set in 1995. For March 31, the mark to beat is 75 degrees, set in 1987.

The high-pressure ridge responsible for the coming sunshine and warmth doesn’t look likely to budge for several days, Gaebel said.

High temperatures across Puget Sound will be in the low to mid-60s on Saturday, with the mercury climbing slightly higher on Sunday. A few areas in the Cascade foothills, like Issaquah and North Bend, could reach 70.

Warmth and sunshine will accelerate the bloom in the Skagit Valley, where the annual tulip festival is set to begin Monday, said Brent Roozen, of RoozenGaarde Display Garden & Store in Mount Vernon.

“In the fields, the early varieties are only a couple of sunny days away from blooming,” he said.
