Pacific Northwest A vigorous shortwave trough will approach the Pacific Northwest coast through tonight before shifting inland over WA during the early morning Wednesday. A deepening surface cyclone will move across southern BC towards southwest AB, with a Pacific cold front trailing south-southwestward. Low-topped convection is expected to accompany the front, initially approaching the WA coast by late evening. Surface-based buoyancy will remain meager, but strong gradient winds will shift from the southwest to west-northwest as the front passes. Sporadic lightning flashes and strong to severe gusts may accompany passage of this low-topped squall before it subsides inland in western WA/OR. Intense lower-level flow will likely peak in the overnight to early morning hours. Buoyancy should remain quite limited along and east of the Cascades, but most guidance indicates broken low-topped convection should spread east along/ahead of the front amid pronounced large-scale ascent. Background gradient winds will likely be capable of producing severe gusts, and some of these may be coincident with sporadic lightning flashes.
