Well, it looks like the convergence zone/low center decided to drop a bit more rain in a little bit of a larger area than expected this morning. Sometimes that happens with weather and models, so hopefully it wasn’t too much of a surprise for you this morning.
Thursday – High 55, Low 49; Scattered showers throughout the day, with mostly calm winds as well. Clouds were mostly cloudy to overcast.
Friday – High 54; More rain than expected, with amounts over 3/4 of an inch in places. Winds were fairly breezy all day, with overcast skies obviously.
WARNINGS – At this point, all we have is a Small Craft Advisory in effect for the waterways, and the continued Special Weather Statement for the Cascades. For more info, please see here.
The short wave through that we saw moving in today has developed into an almost isolated upper level low, so the jet stream has a few extra bends in it. Because of this, as that low continues to rotate and move southeast, the jet stream will actually start to shift to the east as well. This will push some of the cooler air away, hopefully clearing the way for…well, a clear weekend. This trend will continue through most of the weekend, at least until Sunday afternoon. At that point, the jet stream starts to shift back to the west, bringing with it some more cool air and possibly some disturbances as well. By the end of the forecast a small short wave trough will start to move through, which backs up the disturbance theory.
The low that brought in the rain Friday morning will continue to move south, so we can expect the pressure to come up a little bit. There are no high pressure centers on the map, but the weather will make it seem like it. I don’t see any frontal systems, so I will skip this model for this round.
The showers will dry out overnight, and by Saturday morning we should be seeing dryer weather. This will actually continue all through the weekend, so go do something outside while this lasts! Normally I wouldn’t post this model since it’s empty, but there is a system that will be moving in Sunday night. It will probably bring in some showers overnight, so because of that, I will post the model.
However, I won’t post the snow model since there won’t be any to report on. At least most of the mountains got a little bit more snow!
With the showers departing overnight, we can expect the clouds to do the same. And from there, I’m seeing mostly clear skies for much of the weekend. Some high clouds will move in overnight on Saturday, but that’s it until Sunday afternoon. Even then the clouds will be high, but we can still expect mostly cloudy skies by the end of the day.
With the low pressure still hanging close by overnight, we can expect some windy conditions to stick around given our natural wind tunnels. Fairly strong winds will blow tonight, mainly in the Strait, northern islands, south Sound, and the mountains. Central and north Sound will see some windy conditions as well, mainly over the water. These winds will slowly start to weaken through Saturday morning, leaving breezy conditions throughout the Sound. By Saturday night, we will have calmed some more, with slight breezes here and there, mainly over the water. This will continue through Sunday evening, where the incoming system will increase the winds over the waterways once again.
We can expect similar temperatures during the day, but the lows are going to be a bit colder. Highs on Saturday will reach into the low to mid 50s for the entire Sound, with slight cooling in the north. With the lack of cloud cover, the lows will dip quite a bit, coming down to the low to mid 30s (yes you read that right). If you live close to large bodies of water, you may see slightly warmer temperatures, but they will cool real quick as you move inland. Sunday will be almost the same case since the clouds won’t move in until later. Highs will be in the low to mid 50s once agian, but warmer temperatures to the south. Lows will be in the high 30s to low 40s.
TL;DR: Back to the clear winter weather for the weekend: kind of warm during the day, pretty darn cold at night.
