Chilly temperatures will give way to seasonal averages by the end of the week in the Puget Sound region.

“Another cold night ahead, but as the week unfolds, temperatures will gradually moderate,” said KIRO Newsradio meteorologist Ted Buehner. “By the end of the week, temperatures will be close to the seasonal averages for early February with highs near 50 and lows around 40.”

The National Weather Service in Seattle reports Tuesday will be mostly cloudy, with a high near 42. The low Tuesday night will be around 35 degrees.

According to the KIRO 7 TV weather blog:

An offshore ridge will continue to flatten out Tuesday. In addition to that, a warm front moving into coastal areas of B.C will tag us tomorrow. No wet weather is expected except around the Olympic Peninsula/Canadian border.

By Wednesday, another system tags Washington. Light showers around the Olympic Peninsula and north of Skagit County are expected. With Pacific air making a return, high temperatures return to near-normal for the remainder of the week.

“After a relatively dry January, rain returns in time for the weekend,” Ted said.
