Tolchester Beach Report
Rank 704 of 725 in Maryland, Oct 11. The 247 rank orders a state's stations by their 247 score out of 100: how reliably they report, how accurate their readings are against a reference station, how their readings pass their checks, and how they stand against the forecast.
Equal scores are ordered by the share of scheduled reports received, then the reports due in the week (the longer record first), then the median arrival, then the longest silence.

From Storm Station's own record of every report it heard from this station.
Against its reference: each temperature this station reports is compared with the nearest airport or climate reference station that reported within half an hour, up to 15 miles away. The figure is its reading less the reference's, on average, as both were reported; the typical difference is the root mean square. The difference in height is shown where both heights are known.
Its schedule is one report every 18 min, 80 in 24 hours. Two reports in the same 18 min count as one received.
