I noticed Seattle NWS put out a special statement this evening. Seattle and Olympia had their coldest last week of March in history. That would be daytime highs, not average daily temps. I don’t have an intern, so I sat down on the computer and loaded up PDX’s highs since 1941. Looks like it’s Portland’s coldest last week of March as well. The next closest was 49.7 degrees in March 1967, the 3rd coldest was 1999 (50.0). Winter 1998-1999 was a La Nina winter…what do you know!
Moving on, as I mentioned during the 10pm newscast I was very happy to come in today and see warm/dry weather on tap for the rest of the week. This snowy period will be a distant memory in just a few days. The upper-level ridging is not forecast to be that strong the rest of the week. But in April all you need is no storms and no strong onshore flow to get nice & warm weather.
Long range models are all over the place beginning this weekend, so confidence is pretty low at that point.
