34 entries this year. Our average values are:
DCA: 11/17/18
BWI: 11/3/18
IAD: 10/30/18
RIC: 11/16/18
Tie: 4.03"
So a week to 10 days past climo for the most part. DCA value is close to climo I believe. Looks like next week has the first legit threat, particularly for the non-DCA locations. IAD has 1.02" of rain to date for reference.
