Warm November Sets Records / 3RD Warmest All-Time

By Rod Hill on 2021-11-30

Our crazy warm November finishes as the 3rd warmest all-time at PDX in terms of mean temperature.  The mean of 50.4 was 3.3 degrees warmer than normal.  The average high of 56 degrees was the 6th warmest and the average low of 44.7 ties 1983 for the 3rd warmest low temp average in November.  

The last few days have seen three consecutive record highs tied or broken at PDX:

Nov 27 - Record high of 63 degrees
Nov 28 - Record high of 63 degrees
Nov 29 - Record high of 58 degrees 

Despite mild overnight lows near 50 degrees, no high-low records were reached. 

Total November rainfall at PDX was  6.43 inches, well above the monthly norm of
5.45 inches.  It may sound crazy, but rain totals would need to top 9 inches to crack the top 
5 wettest list.  The wettest November on record was back in 2006 when 11.92” of rain was
collected.  Still our water year Oct. 1st - Sept. 30th, is off to a good start with a current total of
10.14 inches.  The surplus may be smaller than you think at +1.45 inches.  

I am eyeing a much colder weather pattern for December with good hope of low Cascade snow levels.
