That cold snap you've been hearing about?
"It is coming," Colby Neuman, a meteorologist with the National Weather Service in Portland, said Sunday night.
"The real cold air starts to come in (Monday)," Neuman said.
The forecast for Vancouver calls for the mercury to dip to 24 degrees on Tuesday night and 21 on Wednesday and Thursday nights.
"Right now we've got Thursday morning being the coldest," Neuman said.
"The outlying areas will certainly be into the teens by Thursday morning, and possibly earlier," Neuman said. He said the big freeze is caused by "a lot of cold air spilling out of Canada. It's just sort of this long, drawn-out process … gradually getting colder and colder."
How about snow?
"There's just a lot of uncertainty with that," Neuman said. "It's going to be cold enough that we could see snow all the way down to sea level.
"Friday looks like the first chance for it."
The forecast calls for rain Monday and then mostly sunny days Tuesday through Thursday.
