The Harrisburg Civil War Round Table will meet on Thursday, April 11, at the Central Penn College Conference Center, 600 Valley Road, Summerdale. Doors will open at 5:30 p.m., and a buffet dinner will be served at 6:15 p.m. Anyone wishing to attend the lecture only should arrive no later than 7 p.m. The lecture will also be broadcast via Zoom.

Pennsylvania State University professor of meteorology Jon M. Nese will discuss new findings on the weather conditions that prevailed during the Battle of Gettysburg in July 1863 and the impact weather had on the outcome of the battle. His presentation will be based on an article that he co-authored; appearing in Gettysburg Magazine, the article discussed the heat index during Pickett's Charge.

Drawing on never-before-used data for a qualitative estimate of the combination of heat and humidity during the battle, Nese will explain that the actual heat index on the afternoon of July 3, 1863, was as high as 105 degrees Fahrenheit, which led to heat exhaustion and heat stroke with prolonged exposure and physical activity. The heat caused many soldiers to faint and be carried from the battlefield insensible.

The lecture is free. There is a fee for the buffet dinner, payable at the door. Anyone wishing to attend the dinner should make reservations by noon on Monday, April 8, by contacting Brian Foster at hcwrt.membership@gmail.com or 717-962-6122.
