SEATTLE -- Temperatures are below freezing across Western Washington and are likely to stay that way through the weekend.
Some overnight temperatures dropped into teens and 20s early Wednesday: 29 at Sea-Tac Airport, 27 at Tacoma, 26 at Everett, 20 in Woodinville and 17 at Graham.
Temperatures are now warming up to the low to mid 30s around the Puget Sound, with a few spots near the shoreline reaching the upper 30s.
As we head through tonight, those temperatures are really going to plummet once the sun sets, said KING 5 Meteorologist Mary Lee. By 10 p.m., we'll be down into the 20s and those temperatures will continue to drop through the overnight hours into Thursday morning.

Conditions are mostly dry, but there's a chance of snow flurries Thursday night and the possibility of snow early next week as temperatures moderate and clouds return.
A weak weather system moving over the top of the ridge will pass just off our coast later Thursday into early Friday for a few clouds and maybe a few flurries, but no accumulations over the interior, said Lee.
However, as the low moves by just off our coast, it will bring another surge of cold air from the interior of Canada, probably dropping our Friday and Saturday highs into the upper 20s to low 30s. Saturday morning should be our coldest temperatures this week. Lee added.
The mountains will be mostly sunny with pass high temperatures in the mid teens to the low 20s. The snow level will be near 500-1,000 feet.
