Up the charts we go.
It’s now the second-wettest April on record in Seattle, thanks to a stubborn storm system that has dropped nearly an inch of rain on the city since yesterday afternoon. As of 2 p.m. today, the official weather-reporting site at Sea-Tac Airport had received 5.45 inches for the month—edging this April past 1996 for the number two spot on the list of Seattle’s soggiest Aprils. Since weather records began at the airport in 1945, only 1991 has witnessed a wetter April, with 6.53 inches falling that month.
We’ve already earned a share of the bronze, and by Friday, we could be gunning for silver.
In the wake of a spectacular hailstorm that blasted through Seattle yesterday afternoon, overnight rains pushed this month’s precipitation total to 4.54 inches, making April 2013 the third-wettest April (tied with 1993) on record at Sea-Tac Airport. The stormy weather, which dropped nearly an inch of rain on the city from Friday through this morning, has since moved on—but with another rainmaker on the horizon, we could threaten April 1996 for the number two spot later this week.
Were this February, today would have tied for the wettest day of the month.
Alas, it’s April, and a much higher standard for sogginess has been set.
While it was intense at times, the 0.37 inches of precipitation that fell this morning at Sea-Tac was a far cry from the record-smashing 1.54 inches that deluged the city on Sunday. Still, it was a decent enough chunk of change to lift this April’s rainfall total to exactly three and a half inches—leaps and bounds above the norm of 2.71.
While you were sleeping, the rain came back.
After tapering off in the early evening yesterday, another batch of moisture rolled through Seattle overnight, dousing the city once more. The early morning soaking boosted 24-hour rainfalls totals to the one-inch mark in some parts of the city—especially north of the Ship Canal—while officially giving Sea-Tac Airport 0.73 inches of precipitation since yesterday morning.
As if that wasn’t enough, more soggy weather is on the way.
Maybe we should just dub it the forecast wrecker?
The Olympic rain shadow turned predictions for a deluge of rain upside down this week, ensnaring the Seattle metro in a web of dryness the majority of the time. Instead of 2 inches of rain in 72 hours, we collected just 0.22—an amount barely worthy of an umbrella.
The dismal totals—no doubt appreciated by most—were the result of strong winds blowing from the west above the surface. As these upper-level winds crossed the coastline into our state, they slammed into the Olympic Mountains, wringing out most of their moisture along the western edge. Places like Forks took the brunt of this, with the city measuring a whopping 5.47 inches on Tuesday and another 2.02 yesterday.
Leave it to March to pick up February’s slack.
A torrent of moisture is forecast to unload on Western Washington this week, drenching the area with up to 2 inches of rain by Thursday. That’s more than what fell all of last month, when ’round-the-clock drizzle only added up to 1.58 inches—making February 2013 the seventh-driest February on record in Seattle.
Already, March has made it clear it won’t be following in its predecessor’s footsteps, with the 0.47 inches unleashed last Wednesday outdoing February’s soggiest day by a good tenth of an inch. That system helped bump our monthly rainfall total up to nearly an inch—an amount that will easily be doubled over the next few days, despite the rapid approach of spring.
