Check out my KPLU podcast on the weekend weather: here.
It is hard to remember such an extended period in March where snow was falling somewhere over the lowlands of western Washington and Oregon. Even yesterday, the persistent snow plagued our region, with the area south of Portland and extending down to Eugene not only getting snow, but record-breaking snow. Eugene had a storm total of 7.5 inches...the most they ever had so late in the season.
But I have good news...I think snow is over for the lowlands...and probably for the rest of the spring. The large scale atmospheric pattern is shifting enough that we should enjoy near normal temperatures for a while (like mid 50s) and believe it or not Saturday should be dry and perhaps a few showers over the western sections on Sunday morning.. During the next few days a deep trough will build in the eastern Pacific and all the weather will head south to California. Here are the upper level maps for Saturday and Sunday...not the best time to vacation in lotus land, but they will get acutely needed precipitation. We are left high and dry...and I mean dry, with a weak ridge extending over the NW. Saturday may get up near 60F.
Here are the 24-h precipitation maps ending Saturday and Sunday at 4 PM. We will see some middle and high clouds and some showers may slip up from Oregon on Sunday, influencing mainly the coastal portions of WA.
The extended models, including gold-standard ECMWF, suggests we will stay in a milder pattern, with rain returning next week. But after 5 weeks of generally below-normal temperatures, 50s will feel quite comfortable and this weekend spring-like.
