Check IAD (4.0" in CF6 and CLI) and BGM (1.6" 7th + 0.2" 6th if that counts).
2.4" MDT rather than 5.5" (that was monthly total)
MDT is correct at 5.5" (3.1" fell on 1/6 and 2.4" fell on 1/7).
IAD should be 4.0" (the early climate daily summary showed 4.5", but the final one shows 4.0")
BGM should be 1.8" (0.2" fell on 1/6 and 1.6" fell on 1/7).
CAR should be 1.9" (latest climate summary)
BDR should be 8.6" (0.2" fell on 1/6 and 8.4" fell on 1/7).
thx for the qc. i have excel set to 'manual' v. 'automatic' calculations. forgot to refresh to update totals before posting.
the forecast totals were to include 1/6 snowfall
IAD - fixed
MDT - ok
BGM - fixed (refreshed calculation)
CAR - 1/6 0.1"; 1/7 1.9" (cli; cf6)
BDR - ok. cli and cf6 both show 1/6 0" and 1/7 8.4" do you have a link for bdr showing 0.2" on 1/6? i know the pns value differed from the both climate reports.
Anonymous likes your MDT decision. Anonymous should have noticed that. -- Anonymous. :)
Xmacis shows 8.4” at Bridgeport.

thx for the confirmation at BDR Don. if you're following along at home then you know how well you did!
With the exception of BDR, I think I did fairly well. In any case, I enjoyed the snowfall.
