AOTW: Temperature Records for KOKC, KLIT & KMEM

This answers to this week’s “Question(s) of the Week” are:

  1. When was the last time Little Rock (KLIT) or Memphis (KMEM) recorded a daily minimum temperature below 0F?
    • The last time either site recorded a daily minimum temperature below 0F was 23 December 1989. KLIT recorded a minimum temperature of -1F and KMEM recorded a minimum temperature of -3F.
  2. When was the last time they recorded a daily maximum temperature less than 10F?
    • *** Since 1950, KLIT has not recorded a day where the the temperature failed to rise above 10F. During this time period, KLIT has recorded only 1 day where the maximum temperature was 10F, which was 24 December 1989. KMEM, however, has recorded two days since 1950 where the temperature failed to reach 10F: 10 January 1962 (6F) and 22 December 1989 (8F).***
  3. Since 1950, has either site recorded a day where the temperature failed to warm to greater than 0F?
    • Since 1950, neither KLIT nor KMEM has failed to warm to greater than 0F.

Congratulations to Tim for his correct answers!
