The Tri-Cities might see some snow this weekend as a complicated weather pattern develops, according to the National Weather Service.
It is expecting an upper-level low off the California Coast to combine with an arctic cold front moving south from Canada.
The chance today of precipitation, which would most likely be rain, is 20 percent. But it predicts a 30 percent chance of rain followed by snow tonight as temperatures drop to the mid 20s.
A 20 percent chance of snow is predicted Saturday and Saturday night.
An increasing chance of snow is expected Sunday and Sunday night in the Tri-Cities.
