A rainy day this late in July in Seattle nearly never happens.

According to the almanac, July 29 is usually the driest day of the entire year, but Monday will break the trend with a solid soaking.

A strong-for-summer cold front is marching through, bringing on steady rain for the first half of the day. The precipitation becomes more showery by afternoon, but Seattle will still see a few soggy pockets for the evening drive, too. People should prepare for damp driving and slippery roads thanks to the rain lifting out dirt and oils that have built up over the summer season.

Highs on Monday will only max out in the 60s from the coast to the Cascade foothills, which is a good 10 to 15 degrees below average for mid-summer. Up in the mountains, there will be rainy passes but snowy peaks, with a couple of inches of snow above 11,000 feet over the summits of Mount Rainier and Baker.

Tuesday will be the transition day between rain and shine, as there will only be a few lingering showers still in the mix. Highs will head back into the 70s as the weather starts to brighten back up.

By mid-week, a large ridge of high pressure begins building in, and warm sunshine takes over just in time for Seafair events for Fleet Week. Highs on Wednesday will hover near 80 degrees, it’ll warm into the low to middle 80s by Thursday, and upper 80s to near 90 for a toasty warm Friday afternoon--quite a turnaround from how things are kicking things off this week. Blue skies and sunshine should make for an ideal backdrop for the Blue Angels as they soar through their practice runs late this week.

Highs should stay in the 80s both Saturday and Sunday around the shores of Lake Washington, so it will still be nice and warm. However, models are hinting at the possibility of some afternoon thunderstorms near the mountains on Saturday afternoon. It's a way out to count on that change for sure.

In the meantime, get ready to ride the weather roller coaster this week from the quick shift of chilly rain to warm sun.
