Very Dry and Cool July

 

July 2014 was a very dry and cool month across central and northeast South Dakota as well as west central Minnesota.  The area averaged a deficit of about 1 to 3 inches of precipitation for the month.  In fact, 2 of the locations ranked within the top 5 driest July’s on record!  Aberdeen ended up totaling only 0.70 inches of rainfall for July.  This ranks as the 5th driest July since records started being kept in 1893.  Kennebec had a whopping 0.24 inches of rainfall in July.  This ranks as the 4th driest July since records started in 1893 also.  Timber Lake’s total precipitation for July ranked as the 6th driest on record with 0.55 inches of rainfall.  Only 3 stations reported monthly rainfall above 1 inch with Wheaton coming in at 2.13 inches.  And, that still ended up being just over an inch below normal!  It was quite a change and some would say totally opposite from just one month ago when most locations recorded near to above normal rainfall for June.  In addition to the dry conditions, temperatures continued the trend of staying below normal for the 11th straight month.  Monthly average temperatures ranged from 3 to 4 degrees below normal for July.  Some locations like Aberdeen, Pierre, Sisseton and Wheaton all ranked within the top 10 of coolest July’s on record.  Pierre and Kennebec were the only locations that reached above 100 degrees in July.
