Updated Sunday 6:15 p.m.
Here comes the heat, again...! Annie Lennox and Company may have to re-write the lyrics for one of our City's unofficial theme songs, as it's sizzling summer sunshine--rather than rain--on repeat in Puget Sound these days.
Sunday was our 5th day in a row above 90 degrees, tying the former record for days-at-or-above-90 at SeaTac (the last time we did so was in August of 1981, so it's been awhile!). North to northeasterly winds carried many of our foothill communites into the middle 90s on Sunday, and Bellingtham soared to a record-shattering 93 degrees as hot, dry continental air rushed down the Fraser River Valley. Those winds also carried plenty of smoke into the region, making for a hot & hazy Sunday afternoon, particularly around Port Angeles, since the worst of the current fires are to the north in British Columbia. The coast managed to stay cooler, with highs in the 70s near Forks and Rialto beach.
We'll see little change tomorrow or even Tuesday, as this persistent ridge of high pressure that has parked itself here for the better part of 12-18 months sits and spins with little movement. There are thundershowers in Oregon that will be monitored closely for lightning (upping the wildfire threat in these dry conditions even more), but most of those should stay south of the Washington state line. Highs around the Central Sound will stay on either side of 90--possibly putting us at 6 or 7 days in a row above 90. Wow!
The longer range models are still *finally* hinting at a nice pattern change-up late in the week, with our high relaxing some and letting cooler air move in from the north Pacific. This should bring temps back down into the middle 80s (still not what we're used to, but perhaps more comfortable to those not doing well with the heat) by Thursday and Friday, and upper 70s and low 80s by next weekend.
What an amazing heat wave!
Hope you're keeping cool,
