It's actually fairly possible SEA could end up slightly below normal for the first half of the month. If so a decently cold monthly average is very much on the table. The first half is not going to be a torch for most places.

As the strong ridge builds next week it seems quite likely we see a bout of fake cold, inversions, and east winds before the long awaited pattern change to retrogression begins. Finally. This reminds me of last winter in several ways.

It shot up to 70F despite the low clouds and high clouds this morning. Quite a bit warmer than expected.

The ECMWF actually shows tonight being pretty chilly up this way. Pretty good N to S gradient going right now. Whatcom County is only in the upper 30s in some places.

Strong wave in 3 late month. GFS and ECMWF agree. It could be something.
