From June 1 to Aug. 31, temperatures averaged 75.6 degrees - about 2.5 degrees above normal.
"We had a very warm, dry summer," Margusity said. "That is the very summary of our summer: warm and dry."
Temperatures of more than 90 degrees were recorded 21 times during summer months, he said.
"That is pretty amazing," he said. "That doesn't happen often."
Rainfall was slightly below average. The Hagerstown area recorded 9.3 inches of rain during summer months - below the average of 10.3 inches, he said.
And temperatures of 80 degrees or higher have been recorded for all but two days in September. Temperatures on both of those days peaked at 79 degrees, Margusity said.
For the past 13 days, temperatures have been 7 degrees above normal.
"And the nighttime lows are high, too," he said.
Toward the end of October, residents should expect temperatures to drop into the 60s. But weather will continue to be dry, he said.
"It's going to take a big storm to get this dry weather out of here," Margusity said.
November is expected to be moderate, but he said residents should expect a cold, stormy winter.
"This whole thing is going to move in the other direction," he said. "It's going to rubberband the other way, and it's going to be a hefty, harsh winter."
