REMARKS --- |
|
|
|
|
|
|
|
|
|
|
|
|
|
Unless otherwise noted, all 1883 data are from observations taken at the Ft. Snelling post hospital station. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Average monthly maximum, average monthly minimum and average monthly temperatures are from self-registering |
|
|
|
|
|
|
|
|
|
|
|
|
|
maximum-minimum thermometers. So far as can be determined these instruments were read and re-set |
|
|
|
|
|
|
|
|
|
|
|
|
|
at about 0700 hours each day. Fixed time averages are from fixed time observations taken daily at |
|
|
|
|
|
|
|
|
|
|
|
|
|
0700, 1400 and 2100 hours. These 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. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Extreme maxima and extreme minima are readings from the station's self-registering thermometers. |
|
|
|
|
|
|
|
|
|
|
|
|
|
NONE OF THE FOREGOING AVERAGE TEMPERATURE VALUES HAVE BEEN ADJUSTED TO THE STANDARD |
|
|

NWS 2400 - 2400 HOUR OBSERVATION DAY. CONTEXTUAL EVIDENCE INDICATES THAT THE 1883 FT. SNELLING |
|
|
|

|

|
|
|
|
|
|
|
TEMPERATURE RECORD CONTAINS NUMEROUS AND SOMETIMES SIGNIFICANT OBSERVATIONAL |

|
AND / OR TRANSCRIPTIONAL ERRORS. |
|
|
|
|
|
|
|
|
|
|
|
|
|
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. 1883 Ft. Snelling annual minimum recorded on 21 January. 1883 annual maximum |
|
|
|
|
|
|
|
|
|
|
|
|
|
recorded on 1 July. Greatest daily precipitation recorded on 6 July. Minimum of 32 F on 7 September. |
