Justin’s Thursday Night Forecast Discussion:
Parts of Douglas county and most of Southern Oregon are under a Winter Weather Advisory until 10am on Friday. The bulk of the cold front is slowly moving through Southern Oregon and Northern California. Sections of I-5 going into the Siskiyous was closed because of heavy snow for a time Thursday night. Colder air is spilling in behind the front, so expect lows to fall into the mid to low 30s. Snow lines will also fall back to near 1000 feet, but there may be brief batches of snow that get close to the valley floor overnight.
The rest of the week and into the weekend, we stay showery and cool with a strong upper level low generating waves of rain into the Northwest. They’ll be weaker than tonight’s but still adding to some possible flood concerns with the heavy rain Thursday and snowmelt from rising snow levels. Highs should stay cool in the low to mid 40s and overnight lows in the mid 30s.
Right now, it appears a nice ridge of high pressure tries to bring some drier weather in time for Santa Monday night and early Christmas Day on Tuesday. Another strong system will bring more wind and rain for the latter half of Christmas Day and the rest of the week. We’ll be watching as we go through the next couple of days. If you’re traveling, remember to always have a kit ready for wintery conditions, especially if you’re headed into the mountains.
Have a great Friday!
