Day 255: Oklahoma City Temperature Climatology (1990s)

As discussed last night, I’m in the midst of a three-day series of posts on the temperature climatology of Oklahoma City during the 30 year period from 1980 – 2009. Last night’s post focused on temperatures in the 1980s, this post focuses on the 1990s, and tomorrow will focus on the 2000s.

Day 255 (a)

Above is a graphic depicting the daily temperature in Oklahoma City, OK from 1 January 1990 through 31 December 1999. In red, the daily maximum is plotted with the “normal” daily maximum temperature in black underneath. In blue, the daily minimum temperature is plotted with the “normal” daily minimum temperature in black underneath. As you can see, we are rarely ever near the “normal” temperature on a given day…

I should also note that the 100F temperature is denoted in a red horizontal dashed line, the 32F temperature is denoted as a blue horizontal dashed line, and the 0F temperature is denoted as a purple horizontal dashed line.

Below are some extremes from the 1990s:

  • Lowest Daily Average:  4.5 (1990-12-22)
  • Normal Lowest Daily Average:  36.0
  • Highest Daily Average:  94.5 (1996-07-07)
  • Normal Highest Daily Average:  83.0
  • Lowest Minimum:  -3 (1996-02-04)
  • Normal Lowest Minimum:  26
  • Highest Minimum:  81 (1998-07-27 and 1998-07-31)
  • Normal Highest Minimum:  72
  • Lowest Maximum:  6 (1990-12-22)
  • Normal Lowest Maximum:  46
  • Highest Maximum:  110 (1996-07-07)
  • Normal Highest Maximum:  94

Day 254: Oklahoma City Temperature Climatology (1980s)

I’m kicking off an Oklahoma City climatology series tonight. This post focuses on temperatures in the 1980s, tomorrow will focus on the 1990s, and Monday night will focus on the 2000s.

Day 254 (a)

Above is a graphic depicting the daily temperature in Oklahoma City, OK from 1 January 1980 through 31 December 1989. In red, the daily maximum is plotted with the “normal” daily maximum temperature in black underneath. In blue, the daily minimum temperature is plotted with the “normal” daily minimum temperature in black underneath. As you can see, we are rarely ever near the “normal” temperature on a given day…

I should also note that the 100F temperature is denoted in a red horizontal dashed line, the 32F temperature is denoted as a blue horizontal dashed line, and the 0F temperature is denoted as a purple horizontal dashed line.

Below are some extremes from the 1980s:

  • Lowest Daily Average: 0.0F (1989-12-22)
  • Normal Lowest Daily Average: 36.0F
  • Highest Daily Average: 95.0F (1980-08-01)
  • Normal Highest Daily Average: 83.0F
  • Lowest Minimum: -8F (1989-12-23)
  • Normal Lowest Minimum: 26F
  • Highest Minimum: 82F (1980-08-01 and 1980-08-04)
  • Normal Highest Minimum: 72F
  • Lowest Maximum: 3F (1983-12-24)
  • Normal Lowest Maximum: 46F
  • Highest Maximum: 110F (1980-08-02)
  • Normal Highest Maximum: 94F
