FREEZING RAIN SHOULD BE A NO-SHOW IN THE PORTLAND METRO AREA AND SALEM ON MONDAY
Almost all evening models (except the ECMWF) are in and show rain staying SOUTH OF SALEM tomorrow morning so that’s what we’ll go with. The are all remarkably similar on the rain band sitting between Salem and Roseburg most of the day. Note the WRF-GFS shows a big soaking around Eugene, but nothing north of about Albany:
There are hints of a few sprinkles far eastside metro area between 4-8am, but at this point (if it occurs at all) it appears to be too little to even produce ice on roads. Something to keep an eye on for the morning commute out there though. By far eastside I mean east of Gresham/Damascus/Estacada. This showed up on the 00z MM5-NAM, HRRR, and our RPM model. Note the colored areas start at .10″
Then after 8am or so it’ll should be dry from Salem northward with quite a bit of late afternoon sun. Actually all day tomorrow looks mainly sunny at Tillamook, Astoria, and Longview!
To reflect the changing forecast, I updated the CHANCE OF FREEZING RAIN graphic for the 10pm show:
