Today we have a chance of rain showers much like we had Friday. Amounts could be more than we received then, but look to be less than a tenth of an inch.
Monday and Tuesday appear dry, and then we switch to a cooler northwest flow of air Wednesday through the weekend. Snow levels could drop to mountain passes about 4,000 feet. It is uncertain how much precipitation we will get. Right now, I’m thinking light amounts so if snow falls, no worries on the highway.
If we get any overnight clearing during that time, we will see areas of frost. On Thursday Vancouver dipped to a chilly 40 degrees while many locations in the outlying areas were freezing. Yacolt was 32, Battle Ground 34 and Moulton Falls 30. Closer to Vancouver, Jackie Beyea reported frost on the rooftops in the Felida/Salmon Creek area.
You can have frost on rooftops and on cars parked outside due to the quick radiational cooling to space from these surfaces even though an official thermometer at 5 feet off the ground registers a temperature such as 34 or 36 degrees.
