Friday-Saturday: moderate movement through the area.
Saturday-Sunday: movement, if any, was obscured by clouds. Only the strong and nimble picked up yardage.
Last night: The tail end of the unstable system is passing through. Isolated shower cells and a westerly wind kept migration to moderate levels. There was definitely a push north and there should be decent turnover at your local patch. Hammond’s Flycatchers are moving through in good numbers. Yellow-rumped Warblers are dripping from the trees. Really, i can’t remember seeing so many. Sure they are usually abundant, but this just seems over the top. Vangaurd Bullock’s Orioles are in the area. Lets take a look at the PNW loops from last night.
