And for me there was a special touch: I flew over some of the storms on my way back from a meeting!
As I noted in my last blog, the air over the region has the potential for major thunderstorms activity if there is sufficient lift to initiate the action.
It started quite early, with a collection of severe thunderstorms passing over the Tri-Cities and moving northeastward. Here is a radar image at 9:08 AM: red is very heavy rain or hail.
But then the amazing happened, a continuous train of very strong thunderstorms started to develop along the eastern slopes of the Cascades and never stopped all day. Let me show you some samples at a few times. First, at 12:30 PM
4 PM--still going
You see that bright red echo (very intense) just east of the Cascade crest northwest of Wenatchee? According to the radar it reached 31,000 ft and it was clearly visible here in Seattle. To prove this, I took a quick pic of it from Mathews Beach Park in north Seattle.
According the observed 12-h rainfall totals some observing locations received .5 to 1 inches of rain from these storms (see graphic)....but I am sure that much heavier amounts fell at places without rain gauges.
According to our computer models, tomorrow should be far drier, with very little thunderstorm activity.
