The Tri-Cities can look forward to a typically mild April — not too cold, not too hot, not too wet, not too dry, says the National Weather Service.
The month follows an unusually cold Tri-City winter and a March that was much damper than usual.
It was the third-wettest March on record in Richland, according to the weather service.
Average highs in April in the Tri-Cities are about 63 degrees at the start of the month, rising to about 70 degrees at the end of the month. Lows typically rise through the month from about 39 degrees to about 43 degrees.
Temperatures will heat up this week, with temperatures possibly hitting 70 degrees on Wednesday in the Tri-Cities. Highs should be in the 60s through the rest of the work week, dropping back into the high 50s by the weekend, according to an early forecast by the weather service.
Lows should be close to 40 degrees or warmer through the weekend, except for Monday night. The Monday night low was forecast at around freezing.
More rain is forecast for the week, with a chance of showers Thursday through Saturday.
