All-time record high minimum temperature in Richmond

RICHMOND, VA (WWBT) - In terms of weather records, Tuesday, July 12, will go down as a historic day here in Richmond.  For the first time in recorded history, Richmond had a low temperature that was 80° or higher.

In fact, the official low at Richmond's International Airport was 81°.  Daily records are recorded from 1 a.m. EDT to 1 a.m. EDT (Midnight to Midnight EST).  There have been nine occurrences where the low temperature was 79°.  There have been a few cases where the early morning temperature was at or above 80° only to fall below 80° before 1 a.m. EDT.

I just happened to be working last summer when we saw one of these cases.  It was a July morning when the temperature had only dropped to 82°.  Temperatures climbed above 100° that afternoon and it appeared there was an excellent chance we would never be able to fall below 80° before 1 a.m. that night.

That evening, a cluster of thunderstorms developed well to our north and never had a direct impact on our area.  However, we did experience a "gust front" or the cool outflow of air from those thunderstorms many miles away.  This allowed the temperature to drop much more quickly that evening and we fell below 80° shortly after midnight.

Looking ahead, if you are longing for some cooler weather, we are going to catch a break from the extreme heat starting Thursday that should last into at least the first half of the weekend.
