9/11 Anniversary Forecast: How This Year's Weather Compares to 2001

The nation will mark a somber anniversary on Friday. Will the weather cooperate with all of the ceremonies scheduled in New York City, Washington, D.C., and rural Pennsylvania? Here is what you need to know.

What to Expect on Friday for the 9/11 Remembrance Ceremonies

Friday marks the 25th anniversary of the September 11 terrorist attacks. As has been tradition with this day over the last 25 years, people will gather to remember the lives lost on this tragic day in American history. Unlike September 11, 2001, a day that saw beautiful weather, rain showers and thunderstorms could roam the East Coast on Friday.

Tuesday, September 11, 2001, was a lovely early fall day for the eastern U.S. Cooler air, low humidity levels, and sunny skies were the story for New York City, Washington, D.C., and beyond. While the day started in the 50s and low 60s, the mercury climbed into the 60s and low 70s as the attacks unfolded.
