The first frost (and first flakes?) are just around the corner
By the middle of October last year, at least 18 major cities in the Northeast had experienced their first frost. Some were a bit late, while others were a bit early.
The Northeast Regional Climate Center says the average date of Allentown’s first frost, based on 1981-2010, is Oct. 16. Our earliest frost ever was Sept. 24, and the latest Nov. 13.
Three cities had measurable snow last year by Oct. 20 — Binghamton, Buffalo and Rochester, New York.
While Allentown’s first measurable snow usually doesn’t arrive until Dec. 7 or later, we’ve had a few instances of earlyseason or preseason snow in the Lehigh Valley.
Remember our “White Halloween” in 2011, when a surprise storm dropped 8 to 10 inches of snow and knocked out power across the region? And no one can forget the Nov. 15 storm that struck the area last year. That snowstorm dumped an official 7.2 inches at LVIA, about 4 more inches than expected, causing a traffic nightmare of jackknifed tractor-trailers, disabled vehicles and minor crashes. Thousands of motorists were stranded, many for more than six hours, on Interstate 78 and Route 33.
