Winter '15 / '16 - Snow Storm #1: Preliminary Verification

Preliminary storm-total snowfalls for Friday though Sunday from CDUS41 and CXUS51 bulletins.  Good coverage and reporting.

DCA STP in question.
Vicinity reports suggest an under-measurement.
Sensitivity analysis on forecasts with a 30" verification shows no impact on top three finishers (HM flips) with minor shuffling in the pack's middle.
Note the SLRs are similar at IAD and BWI.

AP reporting on the controversy.
The two vicinity sites mentioned in the article are ~3 miles NNW (Adams Morgan neighborhood) and ~5 miles NW (Dalecarlia Reservoir) distant from DCA.

Meanwhile ... ~2 miles across the river to the east in Anacostia ... MD ... a trained spotter reported 19" and about the same distance to the SSE a 17" report from National Harbor ... VA

Reporting issues continue at SBY.
SBY/s 6" STP comes from a 'media' report carried in AKQ/s Public Information Statement (PNS).

HYA/s 14" STP comes from an 'amateur radio' report carried in BOX/s Public Information Statement (PNS).

Stations with STP but no SN:H2O had mixed freezing ... frozen ... and liquid precipitation.
