Seattle area hit by smallest rain shower ever?

Seattle area hit by smallest rain shower ever?

For those around Bothell and Kirkland Thursday morning, they must have thought they had overslept a few weeks as they experienced the unfamiliar sight of raindrops falling from the sky.

The shower went over I-405 near Kirkland and quickly fizzled as it headed into Snohomish County.

But how small was the shower?  Here is one description on Twitter @lunatiki:

"Weird. Rode thru a rain shower in Bothell 30 minutes ago. Blue skies everywhere except for one big cloud over the Burke Gilman."

It was weird. A very tiny cell developed over North Seattle and quickly drifted across Lake Washington into Bothell and Kirkland. From the looks of it, it was maybe 1-2 miles across, perhaps even smaller. And after it passed, moments later the sun was out and it was like nothing happened.

We're in a bit of some southerly flow this morning that tapped into some moisture in Oregon and that's what brought a few showers to the Cascades today -- and one lonely shower to the lowlands.

Here is the radar loop from when it happened. Can you find the lonely shower?

There may be a few more of these tiny rain showers today -- especially on the Eastside and east of I-405, as the southerly flow continues. But the flow will flip around to the north/northwest later today and that will kill off these miniature showers and get back to the blazing sunshine over 100% of the area instead of 97% :)
