Monday March 21
Pleasant days ahead, so too, will be additional rainfall. Let’s take a peek.
Today’s precip should end later in the evening, as a high pressure ridge rapidly builds overhead. Temps tomorrow will jump into the 60s in many locations, excluding the far NW corner of the PNW, which may have some cloudiness. There will be a short downturn on Wed, as a very weak system drapes clouds and a few showers over the region, esp north of Eugene. Thursday and most of the day Fri look dry & mild. Temps should pop back up into the 60s in western OR - maybe the low 70s in southern OR; it will be a bit cooler for the Puget Sound).
The last weekend of March is shaping up to be wet, although the models have shifted the second system of the 'double play' (mentioned in our last discussion) farther south into CA. Therefore, we’ll forecast a mix of sun & showers for Sunday Mar 27.
The last few days of March are trending as quite WET & blustery. A series of storm fronts are charting to roll onshore, each with breezy conditions, and cooler temps, esp on Fri, April Fool’s Day.
Most solutions for the first weekend of April are indicating absolutely delightful Spring weather up & down the entire west coast. Temps could top out in the upper 70s from Eugene north; lower 70s over western WA by Sunday Apr 3. Too early to break out the patio shade umbrella, but we can at least begin to hope.
The April 4-8 period looks CHILLY, with the potential for FROST in the Columbia basin & upper desert at some point that week. Why? A cold - for April - interior Canada air mass may move into the heartland, clipping the PNW on the eastern flank. A NE offshore wind could usher in some of that heavy, chilly air into western portions of the PNW through the usual Cascade Gaps. We’ll keep an eye on this just in case it looks highly probable. For now, we’ll forecast a relatively dry, but chilly, pattern that week.
