Textbook Puget Sound Convergence Zone

Living in the Seattle area has always meant having interesting weather. One of the most unique weather features of our area is the Puget Sound Convergence Zone. Weather from the north (often "modified Artic air" or "Frazier River Valley air" or just cooler canadian air) meets warmer, southern air. The two air masses are channeled between the Olympic range to the west and the Cascade range to the east and when these two air masses meet, it usually happens in an area just north of Seattle and just south of Everett, or often generalized as the "Snohomish/King County Line". What a perfect location for a weather buff like myself to live! Here is a very simpified explanation of what usually goes on to create a PSCZ:

Its not surprise that Seattle goes to absolute crap in the snow. The combination of snow, a snow that melts, then a deep freeze (thank you Canada) turns our hills, overpasses and interstate freeways into absolute hell zones. A friend of ours had a 12 HOUR COMMUTE. He got home at 4am. Rear-drive articulated buses don't do well on ice.
