Quite the classic Puget Sound Convergence Zone set up shop in the wake of a strong cold front Friday.

Check out this video, courtesy of SkunkBayWeather.com that shows a slow-motion time lapse of the zone forming and moving through. Note the wind shift from south to north just before the rain arrives.



Let that be a lesson that if the wind suddenly shifts from south to north, you're about to get really wet -- although the dark clouds to your north should be a giveaway as well.

Here is a radar image of the zone as well:



And in case you were curious how windy it was before and during the zone, here is a list of peak gusts from the storm:
