Heat wave of July 20- august 14 1999 is a perfect example of that.
“
July 20 to August 14, 1999
Blistering heat developed across the Carolinas during this final heat wave of the 20th century. During this event, the upper level ridge developed across the lower Mississippi Valley and retreated for a time into the Southwestern United States, a position farther west than is typically observed during our worst heat waves. The airmass was still exceptionally hot, and with westerly downsloping winds over the Appalachians, temperatures reached 108 in Hartsville and Cades, SC. The 105 degree temperatures that developed in Charleston, SC on August 1st broke the all-time record for heat in that coastal city. Temperatures also reached 105 in Orangeburg and Newberry, SC. In Kingstree, SC temperatures reached or exceeded 100 degrees for 10 consecutive days from July 24th through August 2nd.
In addition to very hot daytime highs, overnight lows were exceedingly warm during this heat wave; Sullivans Island, SC recorded a daily low temperature of 84 degrees on August 1st! Wilmington, NC's high and low temperatures of 103 and 83 degrees on August 1st average out to 93 degrees -- the warmest average daily temperature in the Port City's history. Charleston, SC also had its hottest average temperature in history on August 1st, 93 degrees, after a high and low measured at the airport of 105 and 81, respectively. The downtown weather station at the harbor in Charleston had a morning low of 86 degrees that same day, the warmest ever recorded there.
The Mt. Mitchell, NC weather station, at 6,240 feet elevation, reached 81 degrees on August 1st and established a new all-time high temperature for that location.
This heat wave also affected the Mid-Atlantic and Northeastern United States. Temperatures exceeded 100 degrees from Richmond, VA through Baltimore and into Newark, NJ.
@SD this map looks exactly like the one you posted from the models where you suggested more heat release!
