Living in the Pacific Northwest, we do get a lot of active weather due to the geographical landscape that this area provides. Two common weather phenomenons in Western Washington are convergence zones and lenticular cloud formations. Convergence zones develop due to moist surface winds coming around the Olympic Mountains and getting trapped in the valleys with nowhere else to go once they hit the Cascades, except to rise and develop storms clouds. This area of convergence normally occurs in North King and Snohomish counties, but can set up anywhere really depending on the strength of these winds.
Lenticular clouds also are extremely common over the mountain peaks in our area. These clouds usually indicate that a storm system is rolling in. The “Calm before the Storm” clouds as I like to call them, but they can really put on an amazing show, especially if you catch them around sunset in the Northwest.
