October notes...

     Hopefully October has turned the corner on the dry spell we have been in for quite awhile.  Groundwater levels probably need several months of above normal precipitation to not have us enter next summer in a bad situation.

     While doing the temperature rankings it was nice to see October come in the middle of the pack.  October was one of the four months that raised the most concern when I did the 20 year summary a few years ago.  Without looking, I remember January was another month with an eye-popping change from first decade to the second decade.

     As noted last month, a cool ending to the year could change the scope of how this year places in the average temperature... of course nothing could make 2020 an average year.  That ship has already sailed.

Daily Records summary:

     There was one record low temp set on the final day in October.  No record high temps were set this month.  There were two records set for cold high temps, but none set in warm daily low temps.

     2020 temperature records now stand at 14 record highs, 11 record lows.  Eight records have been set for coldest high temps, with 15 days setting records for warmest low temps.  

     Summary 2020 total: 29 warm records and 19 cold records.
