METEOROLOGIST MELISSA FREY’S FORECAST DISCUSSION:
Today is day three of chilly showers, mountain snow and possible thundershowers, all thanks to the same storm. An area of low pressure has stayed pretty much stationary off the northwest coast of Washington. This storm is doing a good job of picking up cold arctic air from the north and moisture over the Pacific, and then carrying it all right here into the west coast.
Thundershowers have been frequent off shore, showers off and on for the valley with snow showers in the Cascades. Mt. Hood Meadows has picked up almost two feet, Santiam Pass over eight inches and over four inches has piled up at Willamette Pass.
Today will be the last that we see of this storm. We’ll see scattered showers, possible thundershowers and about two inches of snow for the Cascades. Highs will stay in the low 50s in the Valley and along the Coast.
Thursday morning the jet stream is going to head north. This will put an end to the showers and bring in some drier and slightly warmer air. Thursday will likely start out foggy and chilly, with sun breaks for the afternoon.
A storm is lined up for Friday. It’s coming from the southwest rather than northwest, which means it’ll be quite a bit warmer. The freezing level will climb to about 6,000 feet Friday which means it’s back to rain for the passes. We’ll see showers for at least the second half of the day. Highs will be in the mid 50s.
With a slight ridge of high pressure overhead, Saturday is looking dry for the most part. Late Saturday night though the first in a series of fronts will move in. Sunday through Tuesday are looking soggy with highs in the upper 50s.
Have a great Wednesday!
