7pm update: Accumulating snow event on track....
Next update: ~1am Monday
My thinking laid out in the
previous post has not significantly changed. I am still forecasting a moderate snowstorm for the DC area with accumulations of 2-4". However,
I believe accumulations will be closer to 4" than 2" -- enough to shovel Tuesday morning. I've also adjusted snowfall probabilities and believe there is now only a 15% chance there will not be accumulating snow, and a slightly greater chance snowfall will exceed 3" (60%). Please see the graphics below for an updated accumulation map and snowfall probabilities.
