That's a relatively safe bet. All years beow about 2/3 of median snowfall (or 100" of snow depth on April 1st at Timberline), were doing neutral years, or weak Ninas or weak Ninos. Most had an easterly QBO (we'll almost certainly be in westerly).
For comparison:
Downtown Portland February record: 75 on Feb 29th, 1968 (the airport was 68.
Eugene hit 78 on Feb 26th, 1932. They've also hit 70 as early as Valentines Day (I do think it's easier for the S. Valley to get warmer temps earlier but is something I can't explain. Only theories).
Keep in mind PDX had a 1-2F warm bias until April 2025. Surrounding NWS sites were 68 or 69. Still a good question but any temperature record will have an mark from a lot of us for that reason.
That fire started this afternoon is already estimated over 12000ac. It has reached the outskirts of Summerland. Homes are being lost to this fire right now.
Yeah, that one was kind of a hybrid. Definitely a stout warm sector leading into it but the 500mb pattern was reasonably amplified, stable, and the boundary layer mixed out well on the 70 degree day.
