EVERETT — Potentially record-breaking weather may turn summer dreams into reality across Western Washington this week.

Seasonal averages of 70 degrees will be eclipsed in the region as high pressure above clears the skies and stops onshore airflow, creating a heat buildup.

“This will be a good time to get yourself ready for the summer,” said Brent Bower, senior service hydrologist with the National Weather Service in Seattle.

The heat is forecasted to peak Wednesday with potentially historic temperatures.

Everett’s record of 81 degrees for that date could easily be bested as meteorologists predict highs in the mid-80s, with inland cities like Monroe or Granite Falls nearing 90 degrees.

Air flow off the water will cool temperatures near the end of the week, but above average heat is expected through the weekend.

This would be the third time the area has experienced unprecedented heat in 2019. Both March and May saw spells of heat that broke previous marks.

“With the exception of April, when it turned cooler and wetter, much of the spring has been in a warm pattern persistently, so that allows for a greater chance to hit records,” Bower said.

While it is unpredictable if the record-shattering heat will continue long term, the National Weather Service is forecasting a desirable summer.

“The outlook for June and for the summer is for warmer than normal,” Bower said.

This week’s weather poses only moderate heat risks, primarily to individuals who are sensitive to heat or with health concerns, but everyone should take precautions.

Drink plenty of fluids, limit outdoor activities and wear light clothing. Don’t leave pets or children in cars.
