Summary


NOAA indicates a 10-39 percent chance of 4 inches of snow well west and northwest of Washington, D.C. (NOAA) In summary, there are still four possible scenarios:

1) a heavy precipitation event that may have snow falling at times and possibly accumulating. The best chance of snow in this scenario would be in the colder suburbs to the northwest and west (with more elevation); that is, if the precipitation extends that far inland. [possible]

2) a light-moderate rainfall event with perhaps some snow mixing in but no accumulation [most likely]

3) a light rainfall event across the eastern suburbs [possible]

4) a complete miss [least likely]

My gut feeling is that a complete miss is the least likely of the bunch. I noted Sunday that we were probably 24 to 48 hours from having the models reach a consensus allowing us to make a definitive call about whether snow would fall in the D.C. area. A day later and we still may be 24 hours away from an answer.
