ANNUAL CLIMATOLOGICAL SUMMARY

FT. SNELLING MN

YEAR: 1876

REMARKS ---

Unless otherwise noted, all 1876 data are from observations taken at the Ft. Snelling post hospital station.

1876 Ft. Snelling temperature record includes ONLY fixed time readings taken daily at 0700, 1400 and 2100 hours.

Foregoing averages were computed by taking the sum of the 0700 and 1400 hour readings

plus twice the sum of the 2100 hour readings and dividing the resulting sum by four.

NONE OF THE FOREGOING AVERAGE TEMPERATURE VALUES HAVE BEEN ADJUSTED TO THE STANDARD

NWS 2400 - 2400 HOUR OBSERVATION DAY AND/OR TO THE MAXIMUM-MINIMUM AVERAGING METHOD.

Monthly mean cloudiness values are the averages based on visual sky cover observations taken daily at 0700,

1400 and 2100 hours local time. A cloudiness value of zero (0) indicates a totally clear sky: a value of five indicates

50 percent cloud cover, etc. 1876 Ft. Snelling record appears to have been poorly kept: some foregoing values,

therefore, are probably in error (e.g. August 1876 precipitation record is probably incomplete, 2.00 inch precipitation

value recorded on 3 April is a probable snowfall value, not a meltwater value). July 1876 precipitation partially estimated.

Highest observed temperature during year was 95 F at 1400 hours on 6 July.

Lowest observed temperature was -25 F at 0700 hours on 9 December. Greatest daily precipitation was recorded on

16 May and again on 20 September. 42 F at 0700 hours on 18 June.
