SPECIAL WEATHER STATEMENTOne of the NOAA meteorologists spoke at a local Amateur Radio Club meeting last month. My understanding is that he talked about El Nino/La Nina, the transition between them , and said that the worst winter in recent memory was the winter of '49-'50, when they had 2 feet of snow in the South King County area, with 6 foot drifts.

...SNOW POTENTIAL THIS WEEKEND AND IN THE WEEK TO COME...
A COLD AND SHOWERY AIR MASS WILL SPREAD ACROSS WESTERN WASHINGTON THIS WEEKEND. SNOW LEVELS WILL FALL TO BELOW 1000 FEET TODAY AND TO NEAR SEA LEVEL OR JUST A COUPLE HUNDRED FEET TONIGHT INTO SUNDAY MORNING. THE BEST CHANCE FOR ACCUMULATING SNOW IN THE NEXT 24 HOURS WILL BE IN THE AREAS WHERE CONVERGENCE FORMS. TODAY AND TONIGHT THAT WILL BE OVER SNOHOMISH COUNTY EXTENDING SOUTHEAST INTO THE CASCADE FOOTHILLS. LOCALIZED SNOW ACCUMULATIONS UP TO 3 INCHES IS POSSIBLE WITHIN THE CONVERGENCE ZONES BY EARLY SUNDAY MORNING. FOR THE REMAINDER OF THE AREA...SHOWERS WILL BE MOSTLY IN THE FORM OF RAIN. THE SNOW LEVEL IS BELOW 1000 FEET SO SOME OF THE HIGHER HILLS COULD SEE A SNOW SHOWER BUT ACCUMULATIONS ARE NOT EXPECTED. ON SUNDAY THE AIR MASS WILL BE COLD ENOUGH THAT THE SHOWER ACTIVITY OUTSIDE OF THE CONVERGENCE ZONE COULD BE IN THE FORM OF SNOW BUT NO ACCUMULATIONS ARE EXPECTED AT THIS TIME. THE AIR MASS WILL BEGIN TO DRY OUT LATER SUNDAY.
MONDAY AND TUESDAY OF NEXT WEEK WILL BE COLD AND DRY.
STARTING WEDNESDAY THROUGH THE END OF NEXT WEEK...THERE IS THE POTENTIAL FOR A WIDESPREAD HEAVY SNOW EVENT SOMEWHERE IN WESTERN WASHINGTON. GREAT UNCERTAINTY INHERENTLY EXISTS IN A FORECAST WITH THIS MUCH LEAD TIME...AND IT IS POSSIBLE THAT A HEAVY SNOW SITUATION WILL NOT DEVELOP. CHECK BACK LATE THIS WEEKEND OR ON MONDAY FOR THE LATEST ON THIS POTENTIAL HIGH-IMPACT EVENT. IF THE POTENTIAL STILL EXISTS AT THAT TIME...THEN THE DRY WEATHER ON MONDAY AND TUESDAY WOULD AFFORD AN EXCELLENT OPPORTUNITY TO PREPARE.

He also said this was looking a lot like that winter, and to expect 2 feet of snow mid-to-late January.
