Weather over Father’s Day weekend to be 10 degrees cooler than normal

Will the weather on Father’s Day weekend be as nice as it was for Mother’s Day last month?

Mother’s Day weekend had sunshine and temperatures in the 70s to mid-80s. Sorry Dads – that will not be the case for this weekend. But don’t put that barbeque away quite yet.

Low pressure aloft in the Gulf of Alaska is poised to move onshore over the weekend. A cool moist and unsettled air mass is associated with this weather feature that will produce showers and a threat of thunderstorms.

“This is definitely a cooler system than we often see this late in the spring, in the June time period. It can happen for sure, but this is a little more anomalous than usual,” Meteorologist Jacob DeFlitch, with the National Weather Service in Seattle told KIRO Newsradio.

Saturday looks to be the wettest day. Lowland areas may have as much as a quarter inch of rain while in the mountains, up to an inch of rain could fall. The unseasonably cool air mass will also bring the mountain snow level down to around 4,500 feet. That trip to Paradise on Mt. Rainier will likely involve snow in the parking lot.

“Not only do we have a chance for showers we have a chance for thunderstorms during the period on Saturday as well,” DeFlitch said. “A lot of that might likely come during a convergence zone that develops across King to Snohomish counties Saturday afternoon into Saturday evening.”

Sunday should be the drier day of the weekend. The threat of showers and thunderstorms will remain, but it should be more dry than wet.

“They’re not going to be as steady or likely as heavy as what we see on Saturday, which is good news,” DeFlitch explained.

He said Sunday will likely be drier earlier in the day than later. So Dads, you might want to try out any new grilling equipment you receive on Father’s Day at lunchtime, rather than dinner.

Mariners to play with closed roof due to weather

Also this weekend, the Seattle Mariners host the division rival Texas Rangers. The roof will likely be closed on Saturday, but there is a chance it will be open for those taking Dad to the game on Father’s Day. Sweatshirts or light jackets will be in order for the three-game series.

High temperatures Saturday will struggle to reach 60 degrees, about 10 degrees below average for mid-June. Sunday’s highs should nudge a bit higher, in the 60-65 degree range for much of Western Washington.

For many, temperatures in the lower 60s on Sunday are still enough to fire up the barbeque, something I plan to do on Father’s Day.
