Highs in the 70s… in August?

A rare breed of summer day might occur Wednesday, the 13th of August - an August day in which temperatures climb no higher than the 70s. I should note that average high temperatures for mid August are upper 80s to around 90.
Cool August days in the 70s are so rare because it takes an unseasonable day-long combination of thick clouds and persistent rain showers to hold daytime temperatures down. These factors may indeed come together Wednesday, August 13th, as a storm system approaches Coastal Carolina from the southwest.
Right now, the official Storm Team 9 Forecast has a high of 80 for Wednesday, but this reflects a degree of uncertainty in how thick morning clouds will be and how soon rain showers will arrive. If clouds begin the day thin, and filtered sunshine breaks through them, temperatures will climb fast. Also, if rain showers don’t arrive until Wednesday afternoon, their cooling presence will be delayed as well. But, if clouds stay thick for the entire day and/or rain showers arrive early in the day, temperatures will likely climb no higher than the 70s.
The last time daytime temperatures were held to the 70s in August was in 2004 - when it happened 4 times! August 6th, 14th, 15th and 29th, 2004 all featured high temperatures in the 70s - and every one of those days featured clouds and measurable rainfall.
