Forecasters extended their warning about dangerously high temperatures through Friday night, and the forecast high for Thursday in Eugene would be a new record high if predictions come true.

The National Weather Service heat advisory for Wednesday and Thursday now extends through Friday night at 8 p.m. A heat advisory means that forecasters expect a period of high temperatures.

As temperatures push the century mark, the City of Eugene invites individuals to cool off in air conditioned libraries, community centers, swimming pools and at spray play areas in parks.

If you plan to exercise outside in hot and humid weather, wear very light, comfortable clothing and work out in the early morning or late evening, if possible.  It’s especially important to know the symptoms of heat exhaustion and heat stroke. If any symptoms appear, stop exercising and cool down immediately by dousing yourself with cold water.

You may need to get medical attention. Heat exhaustion can progress quickly to heat stroke, which can kill you.

From Lane Regional Air Protection Authority

July marks the beginning of summer and hot, hazy days. With the first wave of hot weather this summer, LRAPA would like to remind residents that the heat also brings higher concentrations of ground-level ozone, or smog, which can result in health problems for some people.

“When we experience temperatures in the 90’s and light winds, the ozone levels start to climb and air quality begins to deteriorate,” said Sally Markos, of LRAPA. “There are two problems when this happens: the health impacts it causes for many people, and the possibility of our area exceeding the federal clean air health standard.”

Although the Eugene/Springfield area currently meets the federal standard for ozone, the standard is currently under review by the U.S. Environmental Protection Agency and will be lowered to be more protective of public health.

Imagine working over a hot stove or sizzling asphalt on a 90-degree day. Performing job duties in the heat can be more than uncomfortable – it can also be unsafe. Workers run the risk of developing a heat-related illness when physical exertion is combined with high humidity.

Over the past five years, 33 workers received benefits through Oregon's workers' compensation system for heat-related illnesses.

It looks like a cross between something seen on "V" and a beret, but actually this circular cloud pictured above is just a harmless lenticular cloud. The photo was taken by Annie Roehr over the weekend. (Larger resolution version here.)  The cloud might look like a hat, but it's actually several thin layers of clouds stacked upon each other like a stack of pancakes.

Lenticular clouds can really put on some shows, especially over Mt. Rainier. (I'm still getting e-mails and Facebook hellos over that article, which has been running amok on the Internet for nearly two years now.)

How about a cloud that's not so harmless? Have you seen these photos of the incredible lightning photos from the erupting E...y...ja...z?..q?..., um, volcano in Iceland?

We've been forecasting this for days -- and here it is!

KVAL Weather is forecasting temperatures in the 90s for the first day of fall!

Most of us are asking ourselves -- Is it September already?!

The Ducks head to the high desert on Thursday! What kind of weather will Oregon face?

These next time lapse videos aren't really weather related, but I found them fascinating. This is treating actual photographs with a Photoshop trick called tilt-shifting that makes objects appear toy-like, even though it is actual video. (Here is a video tutorial I found on YouTube)

These videos by Keith Loutit are taken around Sydney, Australia:

The Oregon Coast is seeing more large fish swimming along the ocean blue and we're not talking about tuna fish ... we're talking about sharks.

How would you like to watch the International Space Station fly over Western Oregon?!

It's becoming an annual event -- getting an e-mail announcing that this August, Mars will be as big as the full moon!

Sounds preposterous, and it is.

First, the e-mail says that on Aug. 27, Mars will be as close as it has been in thousands of years and NO ONE ALIVE WILL EVER SEE THIS AGAIN! And then some say it'll be so huge, it'll be as if the sky has two moons.

Let's break down where this e-mail breaks down.
 

Eugene shattered the record high for Aug. 19, topping out at an official 101. The previous record of 100 was set in 1939. The high temp Wednesday still fell short of the all-time high of 108 F.

After feeling more like September and October lately, the heat has finally arrived here in western Oregon. The good news is that the heat wave won't stick around too long.

A little something for everyone over the next few days!

As temperatures push the century mark, the City of invites individuals to cool off in air-conditioned facilities and at wading features in parks.

Hot weather returns to Oregon this week, but will it be record-setting heat? The National Weather Service says the warm spell should start today and last until at least Thursday. The forecast high Tuesday for Eugene is 94, shy of the record 98.

We've been warning you since last week: the heat is on for the start of the Lane County Fair!

We've been seeing more September like weather the last couple of days but things are about to change this weekend and the early part of next week. How does 90 degrees sound?

PORTLAND, Ore. (AP) — The Pacific Northwest has begun a gradual cooldown after days of record and near-record heat.

ALOHA, Ore. – As people around the region try to keep cool and safe in the triple-digit heat wave, tenants at one apartment complex in Aloha say they have been told not to install air conditioning units in their windows.

One stated reason tenants said they were given by the landlord: they look “tacky.”
