A large area of high pressure developed in the upper atmosphere by the middle of July.  Heat built up over Iowa, aided by the severe drought to the south across Kansas, Oklahoma, and Texas.  Temperatures rose into the 90s each day through the period.  Though most days did not see 100 degree heat, the dewpoint and overnight lows were very significant.  Low temperatures during most of the nights were in the 70s, with many of the nights in the mid to upper 70s.  Dewpoint temperatures failed to fall below 70 through most of the period, with frequent excursions in the upper 70s to low 80s.  These conditions caused considerable stress on livestock.  Reports indicated that at least 4000 head of cattle and thousands of turkeys were killed by the suffocating heat.  Livestock losses were estimated in the $5 to $10 million dollar range.
