It's also increased the fire risk -- just yesterday much of the region was under a Red Flag Warning as "downsloping" winds from the west (blowing down the slopes of the Appalachian Mountains) brought with them incredibly dry air (relative humidity below 15% and dew points in the low 30s at National).
This is especially true with winds from the west or southwest, which is considered a warm, "downsloping" direction (air sinks and warms as it's blown from higher to lower elevations).
In this instance, the upslope winds will often cause rain or snow here, but dry weather will hold west of the Continental Divide (remember, they would have an easterly "downsloping" wind there as the air blows down from the Divide).
The question is: can sunshine and a downsloping (warming) wind from the west get us those seven degrees?

It is a downsloping wind, so it might help us squeeze out a few extra degrees of warmth.

Vancouver, being on the southwest side of this high, receives a downsloping wind (warming) and a storm track that bisects the region due to the aforementioned ‘repelling’ action provided by said high pressure.
Tomorrow (Thursday): The sun returns tomorrow and a downsloping wind coming off the mountains should help it be rather warm.
Add in downsloping winds right behind the front and you've got a pretty hot one (despite rapidly falling humidity levels).
Tomorrow Thursday: Winds have a bit more of a northeast component so slightly cooler air may filter in and we won't have the advantage of downsloping.
PM Update: Pleasant fall weather lives on Ian Livingston 2010
Mostly sunny skies and a downsloping wind off the mountains have combined to create a hotter day than recent as highs reach the mid-90s most spots.
