Meteorologist Melissa Frey’s Forecast Discussion:
The Arctic Blast has begun! Chilly air has settled into the Pacific Northwest and is here to stay for awhile. The jet stream is shooting straight into western Oregon from the north. This air is not only cold, but dry. Skies are completely clear, which adds to the cold temps overnight. Eugene dropped to 18° this morning, breaking the record for the low temperature for Dec. 4th.
Highs will stay in the mid 30s this afternoon and then its back down to the teens again tonight. Thursday will look very similar.
Another storm will drop in from the north Thursday night. Models are projecting this storm will form just north of Vancouver Island and will then move south before taking a turn to move inland over western Oregon. It won’t be a soaker, but with our air as cold as it is, this storm will likely bring at least some snow wherever it makes landfall.
The current path takes it inland after midnight near Newport, then into the Southern Oregon Cascades. This path is one that would likely bring snow to the central Coast, central and southern Valley, Umpqua Basin and central and southern Cascades. A small change to the path of this storm would change everything though. If it waits to move inland until Coos Bay, the snow will miss Eugene entirely and hit southern Oregon instead.
The exact location, timing and amounts of snowfall will be better refined once this storm forms in the next 12-24 hours. Stay tuned for updates!
Behind this storm it’s back to dry and still chilly weather Friday night. We’ll stay sunny through the weekend with highs in the mid 30s and lows in the low 20s.
