An excessive heat warning is in effect through 8 p.m. Friday for a sizable chunk of Oregon, with temperatures anywhere from 100 to 115 degrees possible, and dropping only to the mid-70s overnight.
In Medford, the mercury is expected to peak at 114 degrees Wednesday, 1 degree below the all-time record high temperature for the city, set July 20, 1946, 71 years ago.
The temperature reached 104 degrees Monday, five degrees off the daily temperature record of 109 set in 2015. It's expected to top out at 108 or 109 today.
Looking to beat the heat? Here are some tips from Pacific Power:
- Stay hydrated; one easy rule of thumb is to divide your weight in half, then drink that many ounces of water daily, much more if you're exercising in the heat.
- Limit exposure to the sun; wear sunscreen and hats.
- Limit use of heat-producing appliances, such as ovens and dryers, to early morning and late evening. Switch off devices that generate heat, even small ones such as lamps, computers and televisions, when not in use.
- Set the thermostat at 78 degrees, which will keep the house cool but will also save up to 8 percent on power bills. While on vacation, the AC should not be switched off, but raised to 85 degrees instead. That setting allows your air conditioner to use less electricity to cool the house than if the air conditioning has been off all day, but doesn't shut down altogether.
- Use fans to help cool and circulate the air; they use less electricity than an air conditioner when the compressor is engaged.
