Temperatures in the Tri-Cities soon might be climbing into the triple digits, according to the National Weather Service.
It's predicting an extended period of unseasonably hot temperatures beginning late this week.
A ridge of high pressure will build and push into the Northwest, bringing the hotter temperatures and possibly heat advisories, it said.
The high today is expected to be about 82, climbing to 88 Thursday and then into the 100s through the weekend. Monday and Tuesday the high temperature is expected to be about 104 in the Tri-Cities.
The normal high temperature for the end of June is 86.
