What a string of warm days…4 out of the past 5 days we’ve seen temps above 60 in Portland.
Today the dry east wind pushed Salem up to 66 degrees, your warmest February day since 2005! Here are the other records in the Willamette Valley:
Tomorrow should be exactly the same as the east wind keeps the fog away. There will be a dramatic change Wednesday though…a marine push in February! It’ll be coupled with a weakening front dragging through in the afternoon. The combo of the two means cloudy skies, maybe a sprinkle, and temps 10 degrees colder. Check out our RPM model showing the clouds surging up from the south and inland:
Beyond that, no dramatic changes for the next 8-10 days. The upper-level ridge pops up just to our west again late this weekend and early next week. That means more east wind, although it’ll be cooler since we’ll have chilly Canadian air seeping south. The GEM and ECMWF both show about a 20 millibar pressure difference from Spokane to North Bend Sunday afternoon as this cooler air arrives. This could lead to a decent downslope wind event Sunday/Monday. Either way, expect dry weather and sunny skies.
More on the long-term forecast later…the new ECMWF monthly maps are in and still show a big change in the pattern late next week…
