These have been the tops of lively thunderstorms, in an space the place we get excited in the event that they get to 25,000 ft.
We can decide the thunderstorm tops utilizing the native National Weather Service climate radars, which offer echo tops: the best elevation wherein the radars are seeing precipitation. Clouds with out precipitation may prolonged even larger!
The echo-top plot at 6:38 AM Saturday (1338 UTC) from the Camano Island radar exhibits a cell reaching 49,000 ft not removed from Mt. St. Helens. Unbelievable.
And such large thunderstorms throughout that interval have been confirmed by the Portland radar. Here is the Portland radar picture at 7:32 AM….solely 47,000 ft.
These heights have been confirmed by the Langley Hill radar close to Hoquiam.
The seen satellite tv for pc imagery on the time (6:41 AM) exhibits various massive thunderstorm cells, with one in query to the northeast of Portland.
Zooming in, you may see the shadow of the very excessive thunderstorm core (often known as an overshooting high within the climate biz), surrounded by an enormous anvil space.
That tremendous thunderstorm cell has loads of “juice”, with numerous lightning. Here are the lightning strikes for the 30 minutes ending 7:30 AM. Many dozens.
The Saturday morning even was related to a really favorable arrange, with a pointy higher trough approaching, substantial mid-level instability, and an unusually heat/moist air mass.
