If you are looking for info about Storm #1 coming Thursday evening, read the previous post down below. This post refers to Storm #2 for Saturday…
Quick update…finally got a chance to look at all evening models. A few thoughts:
- The evening ECMWF run is now the 3rd in a row to bring a severe windstorm to the I-5 corridor Saturday afternoon/evening
- The NAM model has now joined it, and the GEM (Canadian) is moving the low much closer to us as well.
- Only the GFS is stubbornly hanging on to a position farther offshore.
That means 3 out of 4 major models are producing either a significant or (in the case of the ECMWF & NAM models) severe windstorm for the populated areas between the Coast and Cascade ranges. That includes the Portland Metro Area. By “severe” I mean the strongest storm we’ve seen since the December 1995 event for many of us.
Here is a comparison of those 4 models at either 5pm or 10pm Saturday evening. Notice how the low is much closer to us except for the GFS
As a result the threat for a significant windstorm for all areas west of the Cascades is higher now than it was 24 hours ago.
IF it does appear in the next 48 hours that a big storm is coming, you will have Friday to prep for it…just lots of showers and regular breezy conditions. I’ll keep you updated!
