For those who’ve delighted in the recent sweep of unseasonably warm and sunny days in the Seattle area, enjoy Wednesday while it lasts.

When temperatures hit 78 degrees at 1 p.m. Wednesday, it marked the first time since 1894 — when temperatures started being recorded at the Federal Building downtown — that Seattle has had three consecutive days with temperatures above 75 degrees in March, according to the National Weather Service.

And for those who’ve found it uncomfortably warm, hold on; our more typical chilly and wet weather is on its way back.

“Today is looking pretty nice,” Jay Albrecht, a meteorologist with the National Weather Service in Seattle, said on Wednesday morning. “It’s another cheerful day as long as you don’t look too far ahead.”

On Thursday, the high-pressure system responsible for the warm weather that has broken all kinds of records this week will move into the Central Plains and be replaced with marine air from the Southwest.

“You know what that means,” Albrecht said. “The ocean temperatures are still down in the lower 50s and chilly.”

Thursday’s high temperature is expected to be around 60 degrees in much of the Puget Sound region, which is 15 to 20 degrees below the highs seen on Monday, Tuesday and Wednesday.

The end of the week, through the weekend, is expected to bring what Albrecht calls our “more normal” spring weather, with showers forecast for Friday afternoon or evening and into Saturday.

Sunday looks dry, but another system is expected next week that could bring showers with highs in the upper 50s and lows in the 40s, he said.

“Spring can be a slow season here,” he said. “We can get a week of warm weather in March, and then April and May could be showery and cool.”

While skies are clear, try to catch a glimpse of this year’s third and final “supermoon,” a full moon that may appear bigger and brighter than usual because it’s at its closest point to the Earth during its 28-day elliptical orbit around our planet.

Wednesday is the first time in nearly 40 years that the full moon has coincided so closely with the spring equinox, according to The Old Farmer’s Almanac.
