A cold front is expected to move over the Mid-Columbia on Sunday and Monday, bringing colder air and a chance of snow at higher elevations, according to the National Weather Service.
The chance of precipitation Sunday night is 50 percent and that likely will mean rain in the Tri-Cities.
The snow level should drop to about 500 feet, but much of the Tri-Cities is at about 400 feet.
Today and Sunday, the high should be in the mid-40s in the Tri-Cities, but could drop into the 30s Monday. Lows should drop to the mid-30s tonight and then into the 20s for the next three nights.
