Weather forecast for Portland, Oregon for Friday, June 24, 2022

PORTLAND, Ore. (KOIN) — Another chilly morning to sleep in with temperatures in the 50s. Or, if you prefer, one more chilly morning to run out and put that secret to-do list.

Friday afternoon will be noticeably warmer than Thursday. Highs are in the low to mid 80s. An easterly flow is initiated which sets the stage for a bigger warm up this weekend.

Low temperatures this weekend will hover in the mid-60s. We’re also looking at the hottest temperatures of the year this weekend – possibly the first 100 degrees in Portland since August. From week to week, our daytime high will jump nearly 40 degrees.

A heat advisory will be in effect for western Oregon and Washington this weekend.

* WHAT… Temperatures of 90 to 100 expected.

* WHERE… In Oregon, Lower Columbia, Greater Portland Metro Area, Upper Hood River Valley, Western Columbia River Gorge, and Central Columbia River Gorge. In Washington, Greater Vancouver area, Western Columbia River Gorge and Central Columbia River Gorge.

* WHEN… From Saturday noon to Monday 10 p.m. PDT.

* IMPACTS… Hot temperatures can cause heat-related illnesses. The rivers are cold and fast, and will continue to do so this weekend. Almost every year, people die in rivers in southwestern Washington and northwestern Oregon due to cold water shock during the first heat wave of the season. Warm temperatures can make cool water tempting, but river temperatures in the 50s can easily lead to cold water shock that can kill in minutes.

*ADDITIONAL DETAILS…Sunday will be the hottest day with highs in the mid to high 90s, locally near 100. Highs on Saturday and Monday are expected to be 90 to 95. Overnight temperatures on Saturday evening and Sunday evening should not be too hot. Nighttime temperatures away from cities are expected to fall between 50 and 60.

PRECAUTIONARY MEASURES/PREPARATION… Drink plenty of fluids, stay in an air-conditioned room, avoid exposure to the sun and watch your relatives and neighbors. Young children and pets should never be left unattended in vehicles. Take extra precautions if you work or spend time outdoors. If possible, reschedule strenuous activities for early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light, loose clothing when possible. To reduce risk when working outdoors, the Occupational Safety and Health Administration recommends taking frequent breaks in shaded or air-conditioned environments. Anyone overwhelmed by heat should be moved to a cool, shaded area. Heat stroke is an emergency! Call 911.
