Fall weather appeared to last all of what, two weeks?!
It's no secret that it has been getting chilly recently and a massive cold front is expected to be coming through early next week...which could possibly result in a dusting of snow falling on Monday and/or Tuesday, according to the Washington Post.
While the predicted time frame is still 6 days away, a lot could chance but according to the original article "a wave of low pressure may form along the cold front, which could produce a period of wet snow Monday night into Tuesday."
The odds of it sticking however aren't super high because "air and ground temperatures would probably be too warm for much to stick and the best chance for accumulation would be in colder areas north and west of Washington."
