Quite a bit of rain we got. Definitely wouldn’t advise driving around in that, as it got pretty heavy at times. Unfortunately, since it happened right in the middle of the week, not many of us had a choice.
Tuesday – High 64°F, Low 57°F; Most of the rain fell in the morning, with trace amounts through the rest of the day. Boeing Field had around 0.1in of measurable rain. Overcast for the entire day, winds were very breezy throughout the day as well. Sustained winds were peaking at around 15mph, with gusts at 21mph.
Wednesday – High 59°F; Quite a bit more rain today, with the gauge measuring out about an inch of rain at Boeing Field, more in some places, and more on the way. Skies were obviously overcast throughout the day, and winds were breezy for the day, but not as strong as Tuesday.
WARNINGS – At this point, we only have a Flood Warning out for Mason County, specifically for areas near the Skokomish River. For more info, please see here.
The bad news is that the trough is going to be sticking around for at least a few more days. The good news is that it looks like it will start to weaken some. That means the super cold core of the trough will be weakened by the time it gets to us, if it does at all. It looks like it won’t, because by the end of the forecast period, the trough will split into a weak trough and an isolated upper level low. The low may cause some havoc on us if it moves north, but we’ll have to see how that goes for the next forecast.
I don’t see too much going on with the frontal systems until Friday. At that point, a very strong surface low (possibly associated with the upper level low) will start to move closer to the coast. It won’t bring in a cold front like we’re used to these systems doing, but a warm front will try to move in from the south. It doesn’t look like it will hit by the end of the forecast period, but it’ll be pretty darn close.
The front that brought in all of this rain will move on its way, but it will be leaving behind quite a disturbance. Things will start to dry out overnight, but we’ll still have some scattered showers for most of the Sound. These showers will get stronger as Thursday progresses, especially up in the mountains. By Friday morning, everything will start to weaken and dry out from south to north, so we’ll at least get a little bit of a break from the rain for most of Friday. However, towards the end of the forecast period, you can see the next frontal rain band moving in from the south, so it’s not over yet. The CAPE model is showing some activity Thursday afternoon, but with the temperature being the way it is, there may not be enough of a chance for convective uplift to occur. With that said, we had the thunderstorm roll through north Sound the other day, so I won’t rule it out, but it’ll be an isolated thunderstorm at best.
Snow will continue to fall in the higher elevations, mainly in the north Cascades. This will weaken and die out by Friday morning, but if temperatures up there stay cool enough, there should be more snow moving in with the front, as is evident at the end of the model in the southern Cascades.
We’ll start to see some breaks in the clouds tonight, but I’m still expecting mostly cloudy skies for Thursday and into Friday. Even with the rain moving away on Friday, I’m not seeing any chances for significant sun breaks.
Here are the 24hr precipitation totals,
And here are the 48hr snowfall totals.
Winds will continue to stay on the windy side for Thursday, with the strongest over the waterways, mainly the Sound and Hood Canal. The winds show some signs of calming as the rain moves north on Friday, so we can at least look forward to that. However, it will be short lived, as we can see the winds start to increase again towards the south as that front starts to move in.
With all of this cloud cover we’re expecting, temperatures should be about the same as they have been, if not a little cooler. Thursday will see highs in the high 50s to very low 60s for the entire Sound. Lows will be in the low 50s since the clouds will be acting as an insulated blanket. Friday won’t be much better, with highs in the same range, possibly a little higher with the rain moving away, but not by much. Lows will be the same as well.
TL;DR: Just when the end is in sight, more rain is on its way.
