HYA
STP derived by applying an inverse distance weighting scheme to BOSPNS vicinity reports from Barnstable county.

Snow-to-liquid ratios (SLR) less than 8:1 are not reported for some stations with measurable snowfall b/c significant liquid and / or freezing precipitation also occurred during the verification period.

The 'TOT SLR' field is a quantity-weighted average.
