9/13/2013 9/17/2013 7:00 AM 5 3.50 M M Sorry to have been away during this historic storm. filed a multi-day report of 3.60” from 9/13-9/21. There were sharp gradients of precip in this area, but for the period 9/18-9/21, very little fell. Using a few stations, including CO-WE-413 and CO-WE-388, I will take 0.10” off the total and break this multi-day into 3.50” from 9/13-9/17 and 0.10” 9/18-9/21
