June notes..

       The attention grabber for me at the end of June was the average temperature for the first half of the year.  Comparing it to other years it was 4th highest at 42.77°.  The 20 years average is 39.96°.  Liberty has not had a mid-year average temp below 40° since 2015 at 36.65°.  Comparing decade to decade after 20 years there were two surprises that stuck in my head.  The rise in temperature and the increase in yearly snowfall.  Unless patterns flip both will get attention when the 3rd decade ends in 2027.  Very unlikely for snowfall to get up to the second decade (2008-17),  but it would not take much to get up to the first decade.
















     Back on topic...  The average midyear temp for first decade was 39.63°.  The second decade was 40.29° for a rise of 0.66°.  Through 7 years of the third decade the midyear average is 41.31° for a rise of 1.02° over last deacde or 1.68° over initial decade (1998-2007).

     Looking at the breakdowns the second decade had four years under 40°, so this decade is past that point.  We would need three colder winters to have a chance at it.  The first decade had seven years under 40° with the coldest being in 2003 at 36.54°.  We need three 2015 years in a row for first half temps AND snowfall.  That would solve the slumping sales for snowplows at work.

     We WILL have colder and snowier years in the future.  Questions are when and how often.

  

Daily Records June:

     There was one record high temp set in June (88.0° on June 5).  The two days over 90° both missed the records by 0.5°.  No record low temps were set.  No records for cold high temps were set but two warm low temperature records were broken.  June summary is 3 warm records and no cold records.

     2024 temperature records stand at 4 record highs and 2 record lows.  One record have been set for coldest high temp, with 13 days setting a record for warmest low temp.

     2024 total summary: 17 warm records and 3 cold records.
