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% :)
