A significantly warmer than normal Summer was tempered somewhat by a rainy last couple weeks that brought us very near normal rainfall. The outlook for the late fall and winter ski season and snowpack has not gotten better.
Temperatures well above normal.
As was the case for August, the month of September saw temperature above normal in the City and Airport.
The good news is rainfall was 94% of normal. Most of that fell towards the end of the month.
Looking Ahead – Still Weak El Niño – Still Warm and dry fall and winter predicted?
Even though we got some rain, don’t expect the water restrictions to be lifted anytime soon. There are some weak rain showers coming in the next week or so but it still doesn’t look like enough to really call the ‘wet season’ started.
The monthly precipitation charts from the US NOAA were a little too pessimistic last month when they called for a drier than normal month. Their prediction has shifted quite a bit for October though. Here is their prediction for October from last month
And here is there prediction for October now:
The wetter than normal weather has shifted north and a big pocket of drier than normal weather has come into the Pacific Northwest. We will see how this will work out.
The forecast for November is for the dryness to intensify which will not be good news for skiers.
December looks normal… you can see all the long term charts here. Winter is still looking very dry and abnormally warm. Not a good omen for the snowpack. Fingers Crossed.
Don’t forget you should have Winter Tires or Tires with the snowflake on your car from October 1st to April 1st if you are travelling on mountain passes like the Hump, Sutton Pass or the Malahat.
When will the first snowfall happen? It might be time to start up the contest! 🙂
Happy First of October Hump Day all.
