The temperature hit 100 degrees again Tuesday in much of the Tri-Cities area.
At Hanford the temperature was 100 degrees by 5 p.m., setting a new daily temperature record. The hottest temperature recorded at the Hanford Meteorology Station for June 9 since World War II had been 98 degrees in 1955.
In the Tri-Cities, the high at the Richland airport was 100 degrees Tuesday, according to the National Weather Service. At the Pasco airport the high topped out at 98 degrees. Volunteers who gather weather data for Kennewick for the weather service will turn in their readings Wednesday morning.
Temperatures will start to cool some Wednesday. Highs in the Tri-Cities should be in the mid 90s Wednesday and Thursday, in the high 80s Friday and back to more normal mid 80s Saturday through early in the next work week, according to the weather service.
Typical high temperatures for the Tri-Cities in the second week of June average about 82 degrees.
The unusually hot late spring weather has been caused by a warm ridge of high pressure off the Pacific Ocean that lingered over the region. It now is being pushed to the east, according to the weather service.
