Heat Advisory issued for Sunday and Monday with a side order of smoke

[KIRKLAND, Wash.] – (MTN) The National Weather Service has issued a Heat Advisory from noon Sunday to 9 PM Monday for Western Washington, with temperatures expected to flirt with the 90-degree mark. Smoke is expected to roll into the region and linger through Tuesday.

Saturday Night

Saturday evening will be pleasant with a northwest breeze from 5 to 10 MPH. Temperatures will be perfect for sleeping – 56 to 60 degrees.

Sunday

Sunny skies with light winds will heat things up with highs reaching 88 to 92 degrees. Temperatures will be cooler by the water and hotter in urban canyons and our area hot spots like Totem Lake and Kingsgate. An onshore flow will develop, pulling smoke over the Cascades. The AQI will be moderately unhealthy, 51 to 100 PM2.5. Very sensitive groups should limit their time outdoors and avoid strenuous activity. Photographers will want to have their cameras ready for a brilliant sunset.

Sunday Night

Temperatures will drop to 57 to 61 degrees, and smoke will remain moderately unhealthy, with the AQI between 51 and 100. Smoke tends to be worse at night as cooler air sinks and pulls it closer to the ground.

Monday

Monday’s forecast is complex, which makes it tricky. If the smoke becomes denser than current models, it will moderate high temperatures. Cloud cover is expected to move in from a weak disturbance, and that will also impact the high temperature and how much smoke settles in the area. High temperatures will reach 89 to 92 degrees in the Bellevue-Kirkland-Woodinville area, with an AQI of 51 to 100. Clouds aren’t expected to roll in until very late on Tuesday, but if that accelerates, it will moderate temperatures and convert our smoke into smog.

Monday Night

Low temperatures will be 59 to 65 degrees depending on when the clouds arrive and how much smoke is in the area. Expect cooler temperatures if the current weather models hold and warmer temperatures if the area gets blanketed. AQI will remain 51 to 100. By sunrise, winds will shift to an offshore flow, moderating our temperatures and blowing any smoke left out of our region.

Tuesday Outlook

Tuesday will be mostly cloudy, with smoke blowing out of the region. Expect the AQI to move back to normal by the afternoon. High temperatures will be 80 to 85 degrees with a southwest wind increasing to 7 to 10 MPH. On Tuesday night, there is a small chance of some rain showers moving through the area, cleaning the air out and moderating temperatures back into the 70s for Wednesday.

Here we go again, record-setting heatwave to sear Seattle a second time

[KIRKLAND, Wash.] – (MTN) The Seattle area is poised to break 100 degrees for the fourth time this summer, with a significant heatwave forecasted for the rest of the week. The National Weather Service issued an Excessive Heat Warning, including the Puget Sound Lowlands, from noon on Wednesday to 7 PM on Saturday.

A ridge of high pressure is building over the Pacific Ocean, bringing eyebrow-raising heat to our region, but not as hot as the record-shattering heatwave in June. Temperatures broke 100 degrees three days in a row earlier this year during a historic heatwave that shattered all-time temperature records from Alaska to California. 

In addition to the heat, Western Washington can expect some smoke to move into the region. High-pressure areas circulate counter-clockwise, which will pull smoke up from Southern Oregon and Northern California. Thursday and Friday are looking to be the worst days, but they won’t be like last year’s conditions. Most of it will be aloft, but some near-surface smoke is supported in the models. One other plot twist, the smoke is making Friday’s forecast pretty challenging.

Wednesday will start with partly cloudy skies and a low around 60 degrees F. in the Kirkland-Bellevue-Woodinville area. Temperatures will reach 87 to 90 degrees F. The usual hot spots of Totem Lake, Kingsgate, and the urban canyons of downtown Bellevue will likely get to the 90 degrees F. mark.

Wednesday night temperatures will drop to 62 to 64 degrees F. in our area. We’ll get a bit of offshore flow overnight, making it a bit uncomfortable, and pulling smoke into our region.

Thursday will see high temperatures from 95 to 98 degrees F. with increasingly hazy skies. The dewpoint will be around 60 degrees F., making it feel a little sticky. The air quality will decline to moderate with PM 2.5 in the 55 to 70 range. The record high is 96.

Thursday night will see high-altitude smoke continue to thicken, which will act as a blanket. Nighttime temperatures will be uncomfortable, with lows from 66 to 68 F. Winds will be near calm, with a slight offshore flow. As the air cools, some of that vertically integrated smoke will sink, and there isn’t much wind to circulate the air. The air quality will be moderate, with PM 2.5 in the 70 to 90 range.

Friday’s forecast is a tough call. The more smoke in the air, the more it will help lower high temperatures. The high-pressure area will continue to drive eastward, and the wind will shift to be more west-northwest during the day or early evening. High temperatures on Friday will be 97 to 100 degrees F. for the Kirkland-Bellevue-Woodinville area, which is 15 to 20 degrees above normal. If the smoke is thicker than the models indicate, shaving a few degrees from the high is possible. The air quality will be moderate, with PM 2.5 will be in the 55 to 70 range. I would expect to have the hazy orange glow we’ve seen a few times this year during the day. The record high is only 91 and is destined to be shattered.

Friday night won’t offer much relief again, but the smoke will begin to be pushed out. Lows will be 65 to 67 F. Air quality will be good to moderate, with PM 2.5 in the 40 to 60 range.

Saturday looks to be our fourth day in a row where the area will hit 90 degrees F. Highs will be 89 to 92, with clouds building in the afternoon as marine air pushes in from the coast.
