Saturday was a day of contrast across Western Washington. Vancouver basked in sunshine all day with afternoon highs running in the mid-60s. North of Chehalis to the Canadian border, it was socked in with low clouds and fog, with afternoon temperatures in the mid-40s.
We can thank an easterly flow of air through the Gorge, expanding out over extreme Southwest Washington and into Oregon, for the clear skies. Without it we would be some 20 degrees cooler or so. Some areas in Clark County had fog Saturday morning and others were clear. Regardless, most of the day was sunny.
I must say, after the deluge to end September, I wondered whether we would get a few days of sunny and warm weather. An Indian summer break. Well, we sure did, and it will linger a while longer.
How much longer? Looking at computer forecast models, outside of some pressure changes that may induce some morning fog or low clouds at times, it could remain dry through the end of October.
