Update: Excessive Heat Warning extended through Sunday as heatwave continues

[KIRKLAND, Wash.] – (MTN) The National Weather Service extended the Excessive Heat Warning for Western Washington through 9 PM Sunday as a record-breaking heatwave continues to bake the region.

On Tuesday, the temperature reached 94 degrees at Seatac Airport, breaking the previous record of 92. Wednesday’s high reached 91 degrees, and Thursday hit 94. Forecast models are coming into alignment that a 90-plus degree day on Sunday is likely. If the region reaches the mark, it would be the first six-day streak of temperatures 90 or above in modern history.

Friday

Friday is starting off two degrees warmer than the low on Thursday. High temperatures will be 93 to 97 degrees. The dew point at Seatac is rising indicating it will feel more humid than earlier in the week, making today feel more oppressive.

Friday Night

Winds will pick up overnight, with a light breeze providing some relief. Nighttime lows will be 60 to 64.

Saturday

Bright sun and searing temperatures will bake the area for a fifth day. Highs will reach 93 to 97 in the Bellevue-Kirkland-Woodinville area with almost no wind.

Saturday Night

A shift to a more unsettled pattern won’t start on Saturday night, with skies remaining mostly clear. Nighttime lows will be 59 to 63.

Sunday

Clouds won’t roll in with a marine layer push until early on Monday. The region has a very realistic chance of experiencing six days of 90 degrees or hotter in a row since weather records have been kept in Seattle – the Federal Building or Seatac Airport.

High temperatures will be 90 to 94 degrees.

Monday Outlook

A more normal weather pattern will return next week, with a strong marine layer pushing into the region as the thermal trough and the high pressure system slide away. Monday looks to be party to mostly cloudy, with a high of 79 to 83. There will be an offshore flow with winds from 8 to 12 MPH, providing much needed relief.

Due to our unseasonably cold spring and deep snowpack, area rivers, streams, and lakes remain very cold. It is possible to get hypothermia, even on a 90-degree day. Stream flow is also high, so tubers and kayakers should use caution. Currents are faster than usual. Never swim, tube, or boat near downed trees or low head dams; it is very dangerous.

Do not leave pets or children in your car, even for “just a minute.” Temperatures can soar to over 110 degrees in less than 10 minutes, leading to heat stroke or worse.

Regrettably, due to the current COVID BA.5 surge and community spread of monkeypox, people seeking cooler indoor spaces should consider wearing a tight fighting N-95 mask.

Excessive Heat Warning extended through Saturday as the heatwave continues

[KIRKLAND, Wash.] – (MTN) The National Weather Service extended the Excessive Heat Warning for Western Washington through 9 PM Saturday as a record breaking heatwave continues to bake the region.

On Tuesday the temperature reached 94 degrees at Seatac Airport, breaking the previous record of 92. Wednesday’s high reached 91 degrees. Forecast models are hinting that a high of 90 degrees on Sunday is within reach. If that were to happen, it would be the first six day streak of temperatures 90 or above in modern history.

A thermal trough, high pressure, and light winds have come together to send temperatures west of the Cascades into the 90s and over 100 degrees in the eastern part of the state. Humidity has been a little lower than the initial forecast models, and overnight temperatures have been a few degrees cooler adding a small amount of relief in the morning hours.

Thursday

Clear sunny skies with a light wind from the northwest and north will keep the heat going. The high will reach 89 to 93 degrees through the Bellevue-Kirkland-Woodinville area. Downtown Bellevue and Totem Lake will be the hot spots, while higher spots like Finn Hill and Houghton, as well as along the water, will be a touch cooler.

Thursday Night

Temperatures will stay above 70 until 1 AM to 3 AM, dropping to 6 to 64 degrees close to dawn.

Friday

Friday will be hotter as heat remains entrenched over the region. High temperatures will be 93 to 97 degrees. The models are suggesting that it may be a bit more humid than the previous days, adding a layer of awful for those who don’t have air conditioning.

Friday Night

Winds will pick up overnight, with a light breeze potentially pulling in some marine air. Temperatures will be closer to fine with lows dipping to 60 to 64 degrees around sunrise.

Saturday

Appears to be a near copy of Friday, with just a little less humidity. High temperatures will be 93 to 97 degrees.

Saturday Night

Some clouds start to move in, but not enough to make it mostly or totally cloudy. Lows will be 61 to 65.

Sunday Outlook

Clouds start to move in on Sunday and depending on when they arrive and thicken up will have a significant impact on the high temperature. If they arrive earlier in the day, highs will moderate and be between 85 and 89 degrees. If the clouds arrive later in the day, highs will reach 89 to 93.

Due to our unseasonably cold spring and deep snowpack, area rivers, streams, and lakes remain very cold. It is possible to get hypothermia, even on a 90-degree day. Stream flow is also high, so tubers and kayakers should use caution. Currents are faster than usual. Never swim, tube, or boat near downed trees or low head dams, it is very dangerous.

Do not leave pets or children in your car, even for “just a minute.” Temperatures can soar to over 110 degrees in less than 10 minutes, leading to heat stroke or worse.

Excessive Heat Warning for Western Washington as potential record-tying heatwave begins

[KIRKLAND, Wash.] – (MTN) The National Weather Service has issued an Excessive Heat Warning for Western Washington from noon Tuesday to 9 PM Friday for high temperatures over 90 degrees and lows in the mid-60s.

A thermal trough, high pressure, and light winds have come together to send temperatures west of the Cascades into the 90s and over 100 degrees in the eastern part of the state. Temperatures aren’t being pushed up from an on-shore flow off the east slopes, so humidity will be high in Puget Sound, with dew points in the mid-60s through Friday, making it feel hotter than it is.

Tuesday

Clear sunny skies with a light wind from the north and northeast will send temperatures soaring. The high will reach 92 to 96 degrees through the Bellevue-Kirkland-Woodinville area. Downtown Bellevue and Totem Lake will be the hot spots, while higher spots like Finn Hill and Houghton, as well as along the water, will be a touch cooler. The dew point will be in the mid-60s, making it feel like it is 94 to 99 degrees.

Tuesday Night

Temperatures will stay above 80 until 11 PM to midnight and won’t drop below 70 until close to dawn. Lows for the Bellevue-Kirkland-Woodinville area will be 63 to 66.

Wednesday

Hump day looks to be almost identical to Tuesday, with clear skies and little wind. High temperatures will be 93 to 97 degrees. The humidity will make it feel like it is 94 to 99 degrees. There is a small chance for a slight onshore flow to form late in the day. That will drop the dew point. However, it will also hold the temperatures higher later in the day.

Wednesday Night

Temperatures will hold above 70 degrees well into the night, dropping below 70 between 2 AM and 4 AM. Lows will be 63 to 65 around sunrise.

Thursday

The cooler start means a slightly cooler day ahead, but it won’t be much of an improvement. High temperatures will reach 92 to 96 degrees, with the dew point still holding in the mid-60s. It will feel like 93 to 98.

Thursday Night

Right now, this appears to be the most uncomfortable night of the week. Lows will be 64 to 67, with humidity between 80% to 90%. Temperatures won’t drop below 70 degrees until 2 AM to 4 AM.

Friday

On Friday, the thermal trough will start to move, and the high-pressure area will slide a bit more to the east. High temperatures will reach 92 to 95 degrees. It will still feel like it is 94 to 97 degrees, but the shifting weather pattern will cause the humidity level to decrease by sunset.

Friday Night

Temperatures will moderate slightly, but it still won’t fall below 70 degrees until 1 AM to 3 AM. There will be little wind, and the humidity will still be high, with lows falling to 63 to 65 degrees.

Saturday

Saturday could be the day we tie a weather record of five days in a row over 90 degrees. High temperatures will be 89 to 93 degrees under clear skies. The dew point will be between 58 and 61 degrees, given the area the only day that will feel like a “normal” 90-degree day in Western Washington.

The Week Ahead

Sunday looks cooler, but temperatures will still reach 84 to 87, and the overnight lows will still be above 60. By the start of next week, it appears we’ll return to a normal weather pattern of daytime temperatures in the 70s and nighttime temperatures in the high 50s.

Due to our unseasonably cold spring and deep snowpack, area rivers, streams, and lakes remain very cold. It is possible to get hypothermia, even on a 90-degree day. Stream flow is also high, so tubers and kayakers should use caution. Currents are faster than usual. Never swim, tube, or boat near downed trees or low head dams, it is very dangerous.

Do not leave pets or children in your car, even for “just a minute.” Temperatures can soar to over 110 degrees in less than 10 minutes, leading to heat stroke or worse.

Regrettably, due to the current COVID BA.5 surge and community spread of monkeypox, people seeking cooler indoor spaces should consider wearing a tight fighting N-95 mask.

Sizzling summer temperatures will broil Western Washington during the work week

[KIRKLAND, Wash.] – MTN The average summer Western Washington has been enjoying is about to heat up, with a four-day streak of 90-plus degree weather ahead. A thermal trough, high pressure, and light winds will combine to create a classic Washington summer heat wave.

After 2021, the words “heat wave” may bring back bad memories of three days in a row over 100 degrees – it won’t be that hot. Daytime temperatures will cross 90 degrees Tuesday through Friday, while lows will likely stay in the high 60s. Temperatures won’t drop below 70 until close to sunrise, so there won’t be much overnight relief from the heat.

Sunday

A perfect late-July day awaits the Bellevue-Kirkland-Woodinville area. Skies will be mostly sunny with high temperatures between 80 to 84. Some clouds will start to roll in close to sunset.

Sunday Night

Partly cloudy skies with a light breeze from the northeast with a low of 58 to 61 degrees – perfect sleeping weather.

Monday

It warms up a little more, but the area isn’t roasting yet. Morning clouds will burn off, and the high temperatures will reach 84 to 88 degrees.

Monday Night

High pressure will slide down from British Columbia to our north, and a thermal trough will form overnight. Overnight temperatures will fall to 62 to 64 degrees. On Tuesday, things start to heat up.

Tuesday

Clear sunny skies with a light wind from the north and northeast will send temperatures soaring. The high will reach 90 to 93 degrees through the Bellevue-Kirkland-Woodinville area. Downtown Bellevue and Totem Lake will be the hot spots, while Finn Hill and right along the water might not quite get to 90.

Tuesday Night

Temperatures will stay well into the 70s past midnight before falling to 65 to 67 degrees close to sunrise. Thee won’t be much of a breeze to offer any relief.

Wednesday

The week’s hottest day will get even warmer thanks to a weak easterly flow off the Cascades. High temperatures will be 92 to 96 under clear skies.

Wednesday Night

Temperatures once again will stay well past 70 overnight, falling to 65 to 68 degrees close to sunrise. It will be almost windless, so make sure those fans are ready.

Rest of the Week

On Thursday and Friday, the high-pressure center starts to drift slowly, moderating temperatures a little bit. it is too far out to make an accurate forecast, but models support temperatures reaching 90 to 94 on both days, with lows at night falling to 64 to 67. Friday night might be a little cooler as the high-pressure area starts to move out of our region and the thermal trough breaks up.

Due to our unseasonably cold spring and deep snowpack, area rivers, streams, and lakes remain very cold. It is possible to get hypothermia, even on a 90-degree day. Stream flow is also high, so tubers and kayakers should use caution. Currents are faster than usual. Never swim, tube, or boat near downed trees or low head dams, it is very dangerous.

Do not leave pets or children in your car, even for “just a minute.” Temperatures can soar to over 110 degrees in less than 10 minutes, leading to heat stroke or worse.

If local and county officials believe that there is a heat emergency, cooling centers will be opened. King County, Woodinville, and Kirkland opened cooling centers last year, while Bellevue partnered with area businesses.

Regrettably, due to the current COVID BA.5 surge and community spread of monkeypox, people seeking cooler indoor spaces should consider wearing a tight fighting N-95 mask.
