Autumn Typically Features a Variety of Weather

Late September is when Washingtonians can usually start feeling the change in seasons in earnest.  The month of September begins with an average high of 84 degrees in the Nation’s Capital but that falls to 74 degrees by the end of the month.  However, it isn’t always a seamless transition to autumn and the change in seasons typically yields a multitude of weather.

Such was the case on September 27, 1993.  The day featured high temperatures in the upper 70s but those living in the area at the time will remember what happened in the early afternoon.  That’s when a line of severe thunderstorms brought several tornadoes from Loudoun County, VA to north central Maryland.  Although the spring is when the United States sees the highest frequency of severe thunderstorms, the autumn also sees severe weather as the seasons change.

September 1998 was a warmer than average month in the Nation’s Capital with temperatures reaching at least 90 degrees on ten different occasions.  The final 90 degree day of the month came 16 years ago today when a record high of 95 degrees was set at National Airport (the official weather reporting site for Washington, D.C.).  September 2010 was also a warm month with ten days of 90 degree heat as well.  By comparison September 2011 saw no 90 degree heat.

Fortunately, there is no extreme weather in the seven day forecast.  In fact, tomorrow's weather will feature weather similar to today being mostly sunny and stellar with highs in the low to mid 80s.
