Oddly, the high and low Maximum Temperatures for the month occurred just 2 days apart, 90.6° on the 5th, 70.3° on the 7th. Minimum Temperatures were quite comfortable for mid-Summer, with 22 days falling to ≤55° and only one day remaining ≥60° (62.1° on the 23rd). All Maximum Temperatures occurred within a 2 hour and 22 minute period each day (the earliest being 1551 hours, the latest at 1813 hours). Due to the clear, dry conditions, the diurnal range was wide this month at 27.7°, the maximum being 34.8° on the 6th (88.5°/53.7°) and 31st (89.3°/54.5°), the minimum 15.8° just a day later on the 7th (70.3°/54.5°).

The Max/Min/Mean July Temperatures: 81.8°/54.1°/68.0°.

Splitting the month, the Max/Min/Mean Temperatures were thus:

1st-15th, 80.7°/53.3°/67.0°;

16th-31st, 82.9°/54.8°/68.9°.

Looking ahead to the beginning of August, record heat and continued dry weather.
