BDR: 4.0"

Thx.

The CF6 reports 5" which is also the 1) record snowfall amount and 2) report from a Bridgeport COOP, so maybe some fat-fingering in the bulletin.

See no reason not to accept 4" as the official amount.

After further review, 5" appears to be the best number for BDR.

The 7 PM PNS report of 3.2" was followed by three more hours of snow (0.19 melted) before changeover to FZRA.

BDR's CF6 carries 5"

BDR's CLI bulletin carries 4" which is not supported by the METARs.

Small differences in one station's STP in most cases has little effect on the Contest outcome.

BGR has been amended to 10" in light of proximity reports of the same amount from Brewer and BGR 1 SW.
