Meteorological fall officially began September 1 and
symbolizes the point of the year when temperatures begin to cool relatively
quickly. The average high in the
Nation’s Capital goes from 84 degrees on September 1 down to 74 degrees on
September 30 at National Airport – the official weather reporting site for
Washington, D.C. Although not normally
the case, the start of this September has coincided with the longest sustained
stretch of hot weather of 2014.
September features a wide variety of weather from one year to the next. It can be cooler than average as September 2009 was when the month finished without any 90 degree temperatures. That was a far cry from September 2010 which had 10 days with temperatures in the 90s. Meanwhile, September 2011 was significantly wetter than average, with the remnants of Tropical Storm Lee bringing the Mid-Atlantic Region record rainfall. In fact, September 2011 was the wettest on record in Baltimore.

This September has gotten off to a hot start with
two days in the mid-90s in the Nation’s Capital and warmer than
average weather poised to continue for the rest of the week. That doesn’t mean, though, that the rest of
the month will experience similarly hot weather, but does highlight the fact
that September often features highly variable weather. Also, September is the most active month of
the hurricane season and the Mid-Atlantic Region could be impacted by a
tropical system at some point this month.
In fact, Tropical Storm Dolly was named last night
and will avoid our region as it makes landfall in Mexico. Today is also the 79th anniversary
of the first of only three Category 5 hurricanes in recorded history to make
landfall in the United States. The
Florida Keys were decimated by the historical hurricane on this date in 1935. However, there are no hurricanes anywhere in
the Atlantic Ocean today.
