Weather and Climate Speak

Weather Talk.
El Nino is showing its effects on the PNW region as the fall season progresses towards winter.  As expected during this time of year, low pressure systems are brewing in the waters out yonder.  These weather systems are large with their southern borders reaching well into the warm Hawaiian waters.   This current low pressure cell is tracking north into Alaska while the Jet Stream under cuts the flow from the south.  This effect will drive warm air and moisture toward the northwest for the next 4-10 days. 

   
Climate Talk.
El Nino data shows that the ocean is getting close to replicating the 1997-98 conditions.    Stevens Pass received 466” of snow during the 97/98 season.  Let’s take a closer look at that year.  

Here is the snowfall breakdown for the 1997/98 ski season:
November = 46”
December= 76”
January= 200”
February = 72”
March = 62”
April = 10”

The data shows a nice snowy period from late December through mid-February.  

No El Nino is created equal, but as all weather and climate forecasts are based on historical outcomes, then this is the best comparison that we have to date.  So while we wait for the snow to arrive, enjoy the amazing fall weather.
