Actually 12Z ECMWF is a little east of its 00Z run on Sunday afternoon and night though.

 

Tropical Tibits only allows comparison with previous 12Z run... but WB allows for comparison with 00Z run.

12Z ECMWF is a little west on Monday... but a little more snow in SW WA.  

 

00Z run for Monday morning...

WA coast and North Sound are winners through 4PM Monday. Nice improvements over 00z for those areas.

 

Hopefully we can continue that improvement and get just a little more inland with the 00z tonight.

WRF outstanding again! back to back runs. If I had to make a forecast based on WRF and 4km Soundings 8 PM Sunday, Rain to slowly change to a mix then wet snow PDX metro and all snow Multnomah Falls westward progressing into Troutdale, Gresham east of I-205. That's assuming the WRF is handling the cold air progression correctly.

 

Yeah it sure does look like a snow sounding provided we have enough moisture to take advantage of the cold dry air.

Total snow through Tuesday morning... not as much for the Portland area as the 00Z run.    

 

Still shafted in King County.   Also... the snow shown in the Central Cascades is mostly falling today.

I hope the WRF verifies! Beggars can’t be choosers though.

Widespread 1-2 inches in PDX would be a very good result here IMO. It is nice that every euro run for a while has shown at least an inch here even if it comes in different ways. 

 

The screw zone over king county is pretty sad though...

High temps on Tuesday... unfortunately this is 2-3 degrees warmer than the 00Z run showed.

Everywhere except Eugene which has the coldest high they've been modeled to have during this whole thing.

Still showing about 3-5" up here. I'd be happy with even the low end of the total.

Your lack of offshore flow will help you this time... it results in it being almost totally dry up here.
