Seattle sloshes through wettest April weekend in Sea-Tac history
We all know it rains a lot in Seattle and if you ask the locals, they'll tell you most of it seems to gravitate to the weekends. But if you thought the amount of drenching rains we went through this past weekend was a bit much even by Seattle standards, well, you would be right.
A whopping 1.54 inches of rain fell on Sunday at Sea-Tac Airport, courtesy of a powerful -- and very slow-moving -- trough of low pressure. It came on the heels of another half inch of rain on Saturday that lingered from Friday's soaker of a storm.
The 2.04" of rain made it the wettest April weekend in the history of Sea-Tac Airport, when looking back to its records through 1948. (There have been wetter two-day periods in April, but none this wet across a weekend.)
Sunday alone was the 4th-wettest April day in Sea-Tac history:
- 2.64 4/4/1991
- 1.85 4/19/1965
- 1.71 4/23/1996
- 1.54 4/7/2013
- 1.46 4/3/1991
Obviously that also means Sunday was the wettest April 7 at Sea-Tac. Old record was 0.63" in 1984.
If you add in the 0.33" on Thursday, and the additional 0.73" on Friday, Seattle sits at 3.10" of rain so far in April -- the second-wettest first week of April on record and already ahead of our monthly average of 2.71" with 2/3 of the month left to go -- and plenty more rain in the forecast!
(If you're curious, 6.53" is the record wettest April set in 1991. 4.29" will get us into the Top 5).
It was cold too!
Sunday's high temperature in Seattle was only 47 degrees. That makes it the coldest day since March 10 and colder than all but two days in March -- and all but four days in February!! (Not a record cold-high though, that was 43 set in 1953).
It was a colder official high in Seattle Sunday than on March 22 (49 degrees) when it snowed 3-5" in the Everett area.
Long range models show both continued rain -- and cold as the next two weeks progress, with a particularly chilly snap possible as we exit next weekend into early the week after next.
