The .04" of rain at PDX last night ended 51 days in a row with a trace or less of rainfall, good enough for 8th place on the dry list of days with less than .01 inches. The rainfall today also ended 22 days in a row with not even a trace of rain. The streak of 22 days has been equaled nearly 10 times over the years. The record for no rain is 41 days back in 1967. The record for only a trace of rain is 71 days, also back in 1967. The summer of 1967 was a neutral to weak La Nina season that had a trace of rain between June 23rd - Sept. 1st. Now that is a dry summer! Below is the report from the NWS.
