Several days of sunny skies and above-normal temperatures are forecast, prompting the National Weather Service in Seattle to issue a heat advisory with a warning that rivers and lakes will remain cold.
“At this time, it appears that the warmest day will be Saturday on the coast and on Sunday over the interior,” meteorologists said in a statement Wednesday.
A high of 80 is forecast in Bellingham on Saturday and 83 on Sunday.
