Does The Convergence Zone Mean It Rains More In Lynnwood?
SEATTLE - Those that live in the southern Snohomish/northern King County areas where the rainy Puget Sound Convergence Zone lives probably think they get more rain per year than Seattle.
But believe it or not, the Lynnwood/Everett area gets about the same to perhaps a few inches *less* of rain each year than downtown Seattle.
Yes, it's wetter up there on Zone days, but there are many other days where the fringe of the Olympic Rain Shadow (where the Olympic Mountains block some of the rain coming off the Pacific) keeps the rain lighter in the north Sound areas than the main Seattle area.
It doesn't really make it rain less often, just the rain is typically lighter. So on a soaking day, Seattle might get 0.65" of rain, while Lynnwood gets 0.25", but then on a Convergence Zone day, Lynnwood gets 0.35" while Seattle gets nothing.
