August notes...


       August temps and precipitation went back to the way 2021 has been going. Will July be the odd man out at year end?  Decided to repeat the temp chart I posted last month to show how the trends are going.  Probably will not post more decade charts until the mid-decade after 2022 is over.

















     One note on the chart above: When I did my 20 year summary August was not in the group of four months which raised concern.  The months in the 20 year summary where the decade-decade temp rose more than 1° are January, April, July and October.  This decade is only four years along but August would join that group at this point.     

     On the 'comfort level' this summer August continues where even a cool July made a statement: high dew points.  August added warm nights to minimize the evening release before the next day hit.  The average dew point this month was 2nd among the 24 Augusts in my records, close behind the top spot in 2018 which had an average dew point of 62.54°.          

     Comparing this dew point to all the months in my records this one is 4th highest.  July, 2013 is the top spot with 64.24°, followed by the top August, then July 2006 is just 0.01° behind at 62.53°.  July, 2020 is only 0.02° behind this one.  Then the gaps widen for the following places.  Making a chart for this simply holds up me getting this posted.

     I have checked wind records in other weather stations in our region and it was a very calm August so I am not looking at replacing my anemometer.  


Daily Records summary:

     Two record highs were set, with no record lows set in August.  Five records were set for warmest low temp.  No records were set for coldest high temp.  August daily totals were seven warm records and no cold records.

     2021 temperature records stand at 19 record highs and 4 record lows.  Seven records have been set for coldest high temps, with 20 days setting a record for warmest low temp.  

     Summary 2021 total: 39 warm records and 11 cold records.


     The 20 year average temp through the end of August is 47.24°.  The average temp this year through July is 49.31°.  At this point the year is 2.07° warmer.
