If you want snow go east AI Canada has Calgary receiving snow for a couple of day's early next week.
Fort St. John drops to -16c on Monday night. not bad.
GFS is the coldest model so l guess that's the outlier.

Historically El Nino has its biggest influence in the second half of winter into spring. So I am not surprised to see indications of earlier cold shots now before the torch settles in for January

Also, we are coming off a rare triple dip La Niña. It will take time for the atmosphere to adjust. Given that as well as the fact that we are still in a strongly -PDO cycle, I think there is still good potential for cold and snow late November or December. January is possible but less likely.

October is still dry. Only 5.4 mm so far. Currently, the past year is the 4th driest on record. And that's coming 2 years after the 2nd driest year on record...

Yikes! YVR is at 100.1 mm for the month, and 150.1 mm IMBY.

But it is well-known that atmospheric rivers are quite shallow and thus the mountains block them from reaching further east.

204.3mm thus far in October, as measured at the rain gauge in northeast Coquitlam.

Happy weekend. Enjoy the troffing next week and first significant snow visible on the local Peaks
