Thunderstorms Possible This Evening in Western Washington

 9:30  Update

The showers and thunderstorms are here (see radar image).  And cooler air is moving in from off the ocean.


Lightning at 8:10 PM:

A line of thunderstorms is now moving up western Oregon at this time and is heading into western Washington.

A little after 2 PM, the thunderstorms were evident in the infrared satellite image, with the lightning indicated by red crosses.


A visible satellite image around 3 PM  showed the area of boomers clearly



The weather radar at 3:45 PM clearly indicates some impressive thunderstorm cells:


For short-term forecasts, the chosen tool is the NOAA HRRR model.  Here is the predicted radar image for 8 PM today.   Storms into southwest Washington and around Portland.


At 11 PM, they had moved northward towards Puget Sound.


Thanks to Dr. Peter Bender for suggesting a look at this.

  1. Most of those thunderclouds seem to be hitting the Peninsula...maybe we in the Puget sound area will get a few random bolts? Or maybe this is dissipating before getting here...It should be an interesting overnight experience--if it shows up!

  2. You were not wrong! It feels SO good. Plus, there's a floor show.

  3. I watched the radar throughout the afternoon. The red echoes were coming up from the south. In S Bellevue where I live, the sky grew dark, but suddenly began to brighten again. I went back inside and looked at the radar again, and the red signals were gone. They just vanished as they moved northward through Kent/Renton. Absolutely no thunder/lightning, in fact no rain at all here.

  4. Just another no-show in Everett...Muggy/warm, but even that dissipated.

  6. Were these influential in the kenmore air crash, ? quite heavy rain off shore, i'm sure the Salish sea got good and wet, perhaps the water plane slipped on the drenched water surface. Think "water water every hare" cartoon

  7. Total banger for San Juan island. Lots of radar action just to the east in Haro strait. 3 second count for the thunder and what a hoot.
