Have we just had a really unusual first half of the year, in Southeast Portland weatahr? Doesn't look like it

ERIC NORBERG - In the early morning of May 8, a breezy day with no rain, a large branch fell off a street tree in the 2100 block of S.E. Ellis, causing property damage. An inspection revealed the tree was rotting and partially hollow inside, and it was subsequently removed. On July 1, we closed the books on the rainfall statistics for the first half of 2020 in Inner Southeast Portland – and the 19.65" of precipitation we received is a little better than last year's 17.27", and almost exactly the same as 2018's 19.93". 2017 was a drencher, and we got 33.25" in the first half of the year alone. But 2020 has been pretty typical so far. Our wettest month in 2020 up till now was January – with 9.55 inches, almost three times the January before – but every year is different, and we're used to that here in Oregon. Can we detect any pattern that would hint at the weather here for the rest of the year? Last year, the annual total was 29.75", or about twelve inches more than the first half. In 2018, the annual total was 35.35" here, or just a little more than fifteen inches more than the first half. And in the spectacularly wet year of 2017, the total was 52.28", or about nineteen inches more than the first half of the year.

So, about the only rule of thumb we can give you is that recently, the first half of the year has been wetter than the second half. Don't throw your umbrella away, though, since every year is just a little bit different from every other one in Oregon, and most notably, a substantial fraction of the annual total falls on just a handful of days each year!
