July 2019 was wetter and warmer than normal. My max temp (89.0°)
was 2.7° above normal and my min temp (69.9°) was even a bit more
significantly 4.2° above normal, resulting in the mean temperature
(74.4°) to be 3.4° above normal. My total precipitation of 7.03″ was
3.20” above the normal July value for my station of 3.83. There were
fewer but generally larger daily amounts of precipitation than in June
leading to a bit drier than normal 9 days with measurable precipitation,
Seven of those nine days fell during the first eleven days of the month
when 5.75” was recorded (nearly 82% of the month’s total).

There were only 2 relatively cool days (max temps below 80°) during the
month, both occurring on cloudy, rainy days on the 8th (2.86”) and 23rd
(1.06”). In fact, those were the 2 wettest days of the month. From the
14th till the end of the month temps were frequently at or above 90°
(11 such days when rounded). The warmest temperature for the month
was 96.5° on the 21st, and the coolest was 62.2° on the 25th.

There were 9 days with measurable precipitation, highlighted by the
monthly maximum of 2.86″ on the 8th during an unusually heavy morning
thunderstorm. This was my 5th wettest day ever since records were
started for this location back in January 2017. Three of the five
wettest days I have ever recorded have occurred in July. Conversely
there were 3 notably significant dry periods during July when no rain
fell (12th-16th, 18th-22nd, 24th-31st). With the generally wet
summer, these dry periods did not start showing any adverse trends
in the vegetation in the immediate area.

The highest barometric pressure reading of the month of 30.30”
occurred on the 27th, in the middle of our driest period of the month
(8 days from the 24th-31st). The lowest reading was 29.74” on the
23rd on the day of our 2nd heaviest daily rainfall of the month.

The highest dew point temperature reached during the month was 80°
on the 20th and 21st which unfortunately (for comfort’s sake), also
occurred on the 2 hottest days of the month. There were 26 days in
July when dew point temps were 70° or higher, including 12 days above
75°, spread out throughout the month. The lowest dew point temperature
value was reached on the 1st when a value of 56° was reached. There
were only 4 days during the month when the dew point temps were in the

July had 7 cloudy days, 14 partly cloudy days, and 10 clear/sunny days
with an unusual higher amount of sunny days due to the 3 long, dry spells
during the month. There were 0 heating degree days and 447 cooling
degree days during the month. There were 5 foggy days, 2 windy days,
and 8 days with thunder.

Daily max/min temperatures didn’t vary as much as in the previous few
months, a typical trend of the mid-summer period. My maximum
temperature frequencies included 15 days over 90°, 14 days between
80° and 89°, and 2 days between 70° and 79°. On the minimum
temperature frequency side of things, there were 15 days between 60°
and 69° and 16 days above 70°. The coldest daily max temperature
was 75.9° on the rainy 23rd while the warmest daily min temp of 76.4°
was on the 21st, when the max temp during the month was also reached

The diurnal range daily monthly average was 19.1° (- 1.2°). Our greatest
daily range of temperature was 30.1° on the 2nd (93.5°-63.4°). We had
a total of 13 days with daily ranges above 20°. Our lowest range of
temperature was 8.0° (76.2°-68.2°) on the 8th (our wettest day of the
month). There were only 2 total days with diurnal temperature ranges of
less than 10° throughout the month, occurring on the two wettest days of
the month. .

July 2019 was a typical mid-summer month, with heat, humidity and
occasionally heavy thunderstorms predominating and conversely, some
significantly long dry spells. Tropical storm Barry developed during mid
July (11-19) in the Caribbean, and ravaged Louisiana with flooding rains
but fizzled out before reaching our area. There weren’t any problems
experienced with my weather station during the month thank goodness,
save for my recurring VPs tipping bucket problems. .
