PRECIPITATION

As temperatures were well-above normal, precipitation followed its lead. Though there were no large storms this month, there were certainly many days of measurable rain. The new year actually started out dry as the first rain didn’t fall until the evening of the 4th, and it rained, at some point, each day through the 12th. A brief break occurred until rain began again on the 15th and every day afterward through the end of the month during which 62% of the month’s precipitation total was recorded.  Not a flake of snow or other frozen precipitation fell the entire month.

One thought on “HAPPY VALLEY, OREGON, WEATHER: JANUARY 2018

  1. Thanks for posting your January stats. Amazing that you didn’t hit freezing the entire month!! In Jan 2017 I recall that you not only had several freezing (or below) mins but even a few maxs of 32 or less! Got to compare your report with Roger Cunningham’s – As I recall he usually is warmer and wetter, at least during the winter months. Sure would be great to get Roger on here – I will try and email him to see if he could check the blog out and would have any interest.
