Ingalls runs the Facebook page Tri-Cities Weather and he gives us some insight into the current weather conditions:

"A lot of rain is coming into the Pacific Northwest as the storm track aims at the region for several days."

"Thankfully we won’t have regional flooding like in 1996, which produced heavy rain on top of heavy snow and frozen ground. Still, some flooding on smaller rivers is possible."

"This kind of tracks with what we’ve seen so far this wet season. November started quite wet before drying out during the second half of the month."

Early in the week, temperatures will be warm as the moisture plume is sourced from around Hawaii, a type of atmospheric river called a Pineapple Express.

"The storm track will tilt later this week allowing temperatures to cool and snow to build back up in the mid-elevation zone of the Cascades and Blue Mountains."

In the Tri-Cities, December is on average the wettest month of the year.
