The high pressure has weakened and moved on out and a trough has set up which has allowed the cooler marine layer and associated clouds to roll back in. Starting tonight, I guess we’ll say summer is officially over and by tomorrow we see the first in a series of systems move through that will give us plenty of rain and winds all weekend, and, snow in the Cascades! The sequence looks something like this, what is left of a front brushed the coast Friday is evening, then a warm front passed through tonight, followed by a wet and windy cold front through early morning Saturday, but then slows down so the rain will hang around most of the day, then, a shot of cold air surges through Saturday night into Sunday causing more rain. After ALL that, a high pressure ridge builds in enough to push most of the weather north of the area though there is still a slight chance of a shower here and there.
Now let’s talk a little about that Friday/Saturday coastal weather. First, we can expect several inches of rain for the event, with the heaviest rain occurring late Friday into Saturday morning. The rivers are quite low and will handle the rain without any concern but know that if you are traveling you need to slow down so add extra time to your plans and keep your headlights on. Next the winds, the heaviest of these will occur Friday night into Saturday morning as well. We can expect southerly winds 15-25 gusting to 35, increasing with the front as it pushes through, 25-30 gusting to 40-45 along the beaches. The National Weather Service has already issued a Gale Watch for the coastal water from Friday afternoon through Saturday morning which means some significant seas as well with combined sea building to 15’ starting Friday night into at least Monday. Finally, yes, they are talking snow in the Cascades on Monday but us, temperatures 55-60 for highs Saturday and Sunday, lows 42-47 Sunday and Monday nights.
