The Tri-Cities will be under a fire weather watch from Wednesday afternoon through Friday evening because of possible wind and low relative humidity.
The relative humidity could be as low as 17 percent and gusts in parts of the Mid-Columbia, particularly rural areas, could reach speeds of 30 mph during the afternoon and evening hours, according to the National Weather Service.
The fire weather watch could be upgraded to a red flag warning later this week.
Highs Tuesday and Wednesday should be in the low 90s in the Tri-Cities, dropping to the upper 80s Thursday. Friday should be the coolest day of the week with a high in the low 80s.
Highs should be slightly warmer, in the mid to upper 80s, for the weekend.
