Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
We’re quickly returning to our dry winter forecast which, except for this weekend’s storm and last month’s snow, has been very unusual. We’ve had a pervasive upper level high pressure ridge in the Pacific for most of the winter. Any good storms (ie, major snow and rain makers) have been either ripped to pieces by the ridge or pushed up into Western Canada.
While that has meant great weather in terms of sunshine for the coast and mountains, the valleys have been stuck under the inversions and foggy. Also, we’re not making up any ground on 2013′s record dry year nor laying down some good snowpack for the coming dry season this summer. We’ll see if this trend continues, if so, something to start watching very closely come May-September.
A sizeable ridge of high pressure will move back over top of the Pacific Northwest over the next couple of days, bringing back the sunny skies and offshore winds for the coast and mountains. However, the valleys won’t be as fortunate. These conditions will lead to another temperature inversion (where the cold air gets trapped under the warmer air) for the Willamette Valley and Umpqua, so expect to see little sunshine and thick fog for likely Wednesday through Friday. Highs will be cooler in the low 40s while the mountains under sunshine in the mid 40s and upper 50s at the coast!
Another storm is scheduled to move through next Saturday with another round of rain and snow. However, new model outputs tonight are making it look like it’ll just be a small shower chance at the coast and coast range. Certainly nothing like what we saw last week. We’ll lock in the timing as it gets a little closer.
Have a great Tuesday!
