The average date of first measurable snow at National is December 16, while BWI comes in with December 12 and Dulles is December 11.
Low temperatures Sunday morning across the D.C. area, 10 to 15 degrees below normal, offered a sneak preview of typical mid-November chill.
The weather in Washington in 2014, on balance, has been cool and wet. But not this past September.
With only 24 days of high temperatures at or above 90 degrees in D.C., this summer was pretty tame. In the western suburbs, it was even more blissful.
So strange. The D.C.-Baltimore NWS office has issued 18 tornado warnings in 2014; the Norman, Oklahoma office has issued just 7.
The overall summer result was 0.4F warmer than normal, but it was slightly cooler than last summer and the coolest in five years.
Surprisingly, 2014 actually ranks on the upper end of the summer heat spectrum here in D.C. However, it was a different story in Baltimore this summer.
Since April, spanning 40 days, just 0.17 inches of rain has fallen in D.C. on the weekend and during the day.
It has been a summer full of cool days. If you're in the western D.C. suburbs, the streak you just went through is unheard of in recent history.
Only 16 days of 90 degree or higher heat this year in Washington. After the summers of 2010-12, this one seems like a dream.
