Justin’s Wednesday Night Forecast Discussion:
Lots of rain is expected over the next 12 hours with a slow moving cold front that may bring 1-2 inches of rain inland and much more than that along the coast. Temperatures will stay above freezing overnight so snow lines will be pushed back into the 3000 foot range. Passes and ski resorts will see plenty of heavy snow tonight and Thursday.
Parts of Douglas county, Central Oregon including Bend, and the northern Coast Range are under a Winter Weather Advisory until 4pm on Thursday. Snow accumulations may be from 3-6 inches, and over half a foot or more in the Cascades. High Wind Warnings are up for the coast until 1am Thursday. Beaches may see gusts to 60 mph but slowing once the front passes early Thursday.
Inland valleys have been breezy all day and will stay that way overnight tonight. The heaviest rain breaks down like this: Coast from midnight through 3-4 am, Inland valleys from 7-10am. Behind the front is still plenty of showers with an occasional break but colder air will move in dropping snow levels back down into the foothills around 1500 feet. There’s a small chance some heavier showers might pull snow briefly down to the valley floor but it won’t accumulate like on Tuesday.
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 most if not all of Christmas Day on Tuesday. 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 Thursday!
