The boundary between very cold and very bommy is a straight line across the middle of the province. Like PG is 2c and Ft St John is -26c kinda thing right. Quite the diff.
A PG High would really help to stop the RainTrain. Oh well. Another time.

Not sure why, but its been feeling a lot like October lately :think: :think:
Looking forward to our first 3 day stretch of sun and 20c++ 8-)

Doesn't look severe enough to cause it to flow on its old course and lead to Sumas Lake reappearing. Looks very close though. North Cascades are forecast to be in the bullseye zone for rainfall which is the source of the Nooksack.
