Winter '17 / '18 - Snow Storm #2: Preliminary STP Verifications

Table of preliminary storm-total snowfall by station for THU and FRI from CDUS41 (CLI) ... CXUS51 (CF6) and ... SAUS41 (METAR) bulletins.

Exceptions:
SBY
04-JAN and 05-JAN CLI and CF6 bulletins carried 'MM' as daily snowfall at post-time.  Tipping bucket data unhelpful.

Estimated storm-total snowfall based on inverse distance weighting technique using the four closest STP reports carried in AKQPNS.  STP value subject to change pending updates to CDUS41 ... CXUS51 ... or PNS bulletins.

HYA
Estimated storm-total snowfall based on METARs @ 10:1 SLR.

Suspect SLRs at ORH ...PVD ... and BGM ... a likely consequence of the storm's high-wind conditions.  Looks like BDR applied 10:1 to derive melt-water given hinky 6- and 7-group data.
