The National Weather Service has released an “Excessive Heat Warning” along with an “Air Stagnation Advisory,” and while it may not be hot enough to cook an egg on the sidewalk (but if you do, email us a pic!), predictions are that the temps Wednesday and Thursday will hover around 100+, so be sure to stay cool, drink plenty of fluids and all the other common sense things one should do when it’s really hot.

Here’s the warning/advisory from the bigshot professional weatherpeeps:

Excessive Heat Warning, Air Stagnation Advisory
Statement as of 4:30 AM PDT on July 29, 2009

… Excessive heat warning remains in effect until 6 PM PDT Friday…
… Air stagnation advisory remains in effect until 6 PM PDT Friday…

An excessive heat warning remains in effect until 6 PM PDT Friday. An air stagnation advisory remains in effect until 6 PM PDT Friday.

Hot and humid conditions are expected to continue through Thursday. High temperatures from the upper 80s to 105 will be accompanied by rather humid conditions and only light breezes. Temperatures at night will remain quite warm… falling only into the 60s for a couple hours late at night in most places.

Record high temperatures will be widespread… and SeaTac Airport will likely tie or break its all time record high temperature of 100 degrees. While today is expected to be the hottest day overall… Thursday will be only a degree or two cooler in most locations.

Friday will be somewhat cooler as the low level flow turns onshore … but temperatures in the western Washington interior will still be well above normal with many spots in the upper 80s to mid 90s.

In addition… the stable air mass will limit dispersion of ozone pollutants and air quality will deteriorate.

Precautionary/preparedness actions…

An excessive heat warning means that a prolonged period of dangerously hot temperatures will occur. The combination of hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely. Drink plenty of fluids… stay in an air-conditioned room… stay out of the sun…and check up on relatives and neighbors.

If you are concerned about the buildup of pollutants… check with your local air quality agency for further information.
