We usually don’t get windstorms like that until fall or winter. But conditions were just right for this time, and did it do it’s damage. The “Supermoon” Windstorm (because the supermoon occurred that night) brought down trees and debris on the interstate, took out power for much of the Sound (with some people still waiting for it to come back), and caused a fatality when a tree fell on a man’s car. Hopefully this will be it for the year.
Friday – High 76°F, Low 64°F; Scattered showers in the morning and evening, with mostly to partly cloudy skies throughout the day. Winds were on the variable side, with stronger speeds in the morning.
Saturday – High 75°F, Low 59°F; The day of the Supermoon Windstorm. The day started with rain that continued for much of the day for most of the Sound, with some areas getting more than others (basically north Sound due to the convergence zone). Then the winds started to pick up by mid morning and didn’t let up until the evening. Boeing Field saw their strongest gust at 39mph, while north Sound (specifically Everett) received a 60mph gust at one point. Sustained winds peaked at around 25-30mph.
Sunday – High 68°F; Kind of feels like a hot autumn day with all the leaves blown everywhere. Partly cloudy all day, with some scattered showers around the Sound. Winds are still on the breezy side, but not as bad as Saturday.
WARNINGS – Only 2 warnings to mention tonight: A Small Craft Advisory for all Sound waterways, and an Air Quality Alert for the other side of the Cascades. For more info, see here.
FIRES – Still quite a few fires out right now, but hopefully this rain will start helping some. There are too many for me to report on tonight, so for a map of the fire locations see here, and for details on the fires themselves see here.
Well, the trough has moved on, but we’ll still be right on that border of the warm more-stable air to the south and the cool less-stable air to the north. By the time Tuesday rolls around, a new trough will start to form and push it’s way out of the general mass of air. The new leading edge will slowly start to envelope us by midday, and will continue to push east by the end of the forecast.
Not much in the way of fronts and the like, but the pressure will be lower than what we’ve been used to for the summer. At the end of the forecast, we see a low move south a little, but it looks a bit on the weak side so I’m not expecting too much from it right now. We’ll have a better idea of that on Tuesday, but for now I’ll at least post the model so you can see.
The rain isn’t over yet, but the worst has definitely passed. Expect showers to increase overnight, with most of the rain staying in the mountains. Monday will see increasing showers in the afternoon/evening, drying out by the time you go to bed. The rain will once again stay in the mountains overnight, but by Tuesday morning it will move back down to to the lowlands and dry out by the end of the forecast. I’m not holding out a whole lot of hope for thunderstorms on this batch, but if there were to be any, it would be Tuesday afternoon in north Sound. I won’t post the model.
Don’t expect too much in terms of direct sunlight for the next couple of days. With the pressure on the lower side, clouds will be sticking around for much of the day. Expect mostly cloudy skies for both Monday and Tuesday, with Tuesday having a better chance at some clearing.
Here are the 24hr precipitation totals.
Winds will still be on the breezy side, but nothing like we saw on Saturday. Expect strong winds for much of Monday, mainly over the water but it will spread out overland as well. The winds will calm by the evening hours, and stay that way for the most part through Tuesday, with some slightly increased speeds.
Temperatures will be on the cool side of warm for the foreseeable future, so at least there’s that. Monday will see highs in the mid to high 60s for the entire Sound, warming a little to the south. Lows will be in the high 50s. Tuesday will be the same for both highs and lows, but with a little more uniform high 60s for the highs.
TL;DR: Cool, not as windy, and kinda wet. Much better.
