Weekdays Are Dry But Recent Weekends Have Been Wet. Why?

By Abby Acone, KOMO News

More beautiful weather is expected through Friday but rain is forecast to return to western Washington just in time for the weekend, prompting questions about why the end of the week has been so soggy recently.

For much of western Washington, most weekends in May were noticeably wetter than weekdays, but data for June shows quite the opposite; there was a higher amount of rain weekdays compared to Saturdays and Sundays. Keep in mind, the numbers are somewhat skewed in June because we had a very rainy day on June 9.

Still, when you put together the total numbers from May through Wednesday at Seattle-Tacoma International Airport, weekends totaled nearly 2.5 inches of rain, which was more than the weekday totals of almost 2 inches.

While Puget Sound residents are resilient to rain, many just wish it wouldn’t fall on the weekends.

“I’m looking forward to there being sunshine in the morning and lasting the day, and also on the weekends,” said Kathy Dugaw, who lives in Seattle.

Meteorologists say our recent trend of wet weather coinciding with weekends has been the result of bad luck and bad timing.

“It’s bad luck,” said local climatologist Nick Bond. “And so there’s nothing that we could really attribute it to except for just one of those flukes.”

Storm systems have just happened to impact the state on Saturdays and Sundays, and there isn’t a particular reason as to the timing. There are some nationwide studies that suggest it rains more on certain days more than others, but some meteorologists KOMO News asked said the evidence is contradictory and unimpressive.

“They’re very weak and there’s conflicting information,” Bond said.

Bond says the area’s last six or seven June months have been warmer than average, so it leads people to believe our cloudy, wet weather this year isn’t normal.

“So, what we’ve been having isn’t that unusual,” Bond said. “And what’s unusual is the last few years were kind of on the dry, warm side.”

The Climate Prediction Center is forecasting abnormally dry and warm weather through the end of June, but that isn’t to say showers still won’t coincide with weekends.
