July hottest in at least two decades

July was hot, hot and even more hot. And as August begins, weather predictions don’t give much hope of any relief in sight for Bolivar and southwest Missouri. Paired up with the heat of July were even drier days.
The last noticeable precipitation recorded in Bolivar was on July 13 with 1.32 inches of rain. According to the National Weather Service, a persistent ridge of high pressure, centered over the plains for the past few weeks, has led to temperatures in excess of 100 degrees across much of the region. Since the last week of June, there have been limited breaks in the consistently hot temperatures.

In addition to the extreme heat, the high pressure over the region has acted to suppress rainfall. This has resulted in drought conditions slowly beginning to affect portions of the Ozarks. The National Weather Service Station at the Bolivar Wastewater Treatment Plant recorded 29 days in July with temperatures of 90 degrees and above, with nine of those days 100 degrees and above. July 2011 was the hottest month on record since the BH-FP started reporting daily highs and lows in 1992.

During the month of July, 22 consecutive days were 90 degrees and above, and four days consecutively the temperature reached 100 degrees and above. The highest temperature recorded at the wastewater treatment plant was 103 on July 29, which was actually the high for July 28, as the daily weather readings at 8 a.m. reflect the 24-hour period prior to the readings. There were 21 days in July when temperatures were 95 or above.

The average daily high temperature in July was 96.3 with an average low of 69.9.
Last time Bolivar has seen temperatures even close to these extremes was in July 1999 with 20 days hitting 90 degrees or above with 13 of those days consecutive. Last July, Bolivar hit 90 degrees 18 days out of 31, even though the average temperature in July 2010 was only 89.9 degrees.

Springfield stats
The NWS in Springfield recorded eight days with temperatures at or above 100 degrees during the month of July with 21 days at or above 95 degrees. Joplin experienced 19 days with 100-degree days and 27 days at or above 95. pringfield recorded 28 days with temperatures at or above 90 degrees and an average high temperature of 96.2, while Joplin’s average high temperature was 99.2 degrees for the month. That made July 2011 the third-hottest month on record in Joplin and Springfield. The highest temperature ever recorded in Springfield was 113 degrees on July 14, 1954.

Joplin tied or broke the previous record high temperature nine times in July, with Springfield breaking a record high temperature only three times. Even the record-high low temperature was broken four times in Joplin and once in Springfield. Joplin recorded low temperatures of 80-83, while Springfield’s new record low of 78 degrees was set July 22.

Weather forecast
The Ozarks is under an excessive heat warning issued by NWS through at least tomorrow (Thursday) with an elevated fire weather risk with relative humidity values ranging from 20 to 30 percent in the afternoon.

“Oppressive heat and humidity will continue through at least Thursday,” the NWS stated. Temperatures are expected to be between the upper 90s and 106 with heat index values between 100 and 112 degrees.

Heat safety
Heat is the No. 1 weather-related killer, especially to the elderly, infants and people with chronic health problems. Heat is especially dangerous to those who live in urban areas where the heat is enhanced due to concentrations of concrete, which is slow to release heat at night. While heat-related illness and death can occur due to exposure to intense heat in just one afternoon, heat stress on the body has a cumulative effect, making long-lasting periods of high heat particularly deadly.
