Back to work and all of a sudden it's December! Seems like November flew by. November ended up to be a cooler than average month by three degrees. It might be hard for you to believe that, if you recall, we hit 70 degree temperatures the first two days of that month! Winter is officially here, now. Meteorological winter is recorded as December, January and February. However, the winter solstice is on Saturday, December 21st at 12:11p.m. EST.
Now that we've turned the page to December, we are starting with near average temperatures. We begin the month with an average high of 52 degrees on the 1st. By the end of the month, our average high at Reagan National drops to 44 degrees.
With less daylight and colder temperatures, we typically see our first measurable snowfall at Reagan National. December gets 2.3" of snow on average for the month. The snowiest day on record was December 19th, 2009 when we had 15" of snow in 24 hours. There have also been plenty of Decembers with zero snowfall.
The coldest December day bottomed out with -13 degrees on the 31st back in 1880. And, the hottest December day featured a high of 79 on December 7th, 1998. Our forecast for the first week of the month has highs and low points. We should hit 60 degrees on Thursday, but by Sunday, it will be cold and back in the 30s with a chance for some snow.
