The weather conditions could snarl traffic for commuters and drivers who are heading to the Seattle Seahawks football game in Seattle on Monday night.
Driving over the mountains also could be dicey. Emergency crews had to close all lanes of Interstate 90 overnight due to winds and falling trees. The closure caused crippling delays for hundreds of drivers on both I-90 and Highway 18. I-90 reopened at 6:30 a.m.
The current forecast calls for dropping temperatures throughout the day on Monday. Rain and snow showers or flurries are possible this afternoon north of Everett. A few light flurries also are possible this evening in the Seattle-Tacoma area.
As of daybreak Monday, temperatures had fallen into the 30s across much of Puget Sound region. Some selected 8 a.m. readings:
Mount Vernon, 37
Port Angeles, 37
Sea-Tac Airport, 40
Meteorologist Doug McDonnal with the National Weather Service says the forecast calls for much colder, drier air Monday night with temperatures in the 20s. He says there's a chance of rain or snow showers but most lowland areas won't likely see accumulating snow.
McDonnal says it's going to be quite cold for much of the week.
