Yes, it looks like a Monday out there. After a gloriously sunny weekend, the rain clouds have quickly returned.

And the rain will be enough to give the greening grass a good drink, tallying nearly a half-inch in spots, especially along the Cascade foothills and through the mountain passes.

Misty clouds and morning fog will greet us on the Tuesday morning commute. And while the showers dry up, moist northwesterly flow over western Washington will maintain a mostly cloudy sky through midweek.

By Thursday, though, full sunshine resumes as high pressure builds over British Columbia and eventually slides along the lee side of the Rocky Mountains: a textbook weather pattern for a West Coast warm-up.

High temperatures Friday through Sunday will surge into the 70s. Had this been mid-summer, we would be talking about record-setting heat. But the lower sun angle and longer nights will prevent runaway temperatures this time. Even still, Saturday will feel like a summer day, with daytime temperatures peaking in the mid-70s.

This fair-weather honeymoon comes to an abrupt end next Monday as cooling showers look to squash the late-season warmth.
