REMARKS ---

 

 

 

 

 

 

 

 

 

 

 

 

 

Unless otherwise noted, all 1869 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 first used at the Ft. Snelling

 

 

 

 

 

 

 

 

 

 

 

 

 

station on 25 October 1869 and were read and re-set at about 0700 hours each day.

 

 

 

 

 

 

 

 

 

 

 

 

 

The foregoing 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.

 

 

 

 

 

 

 

 

 

 

 

 

 

Observed monthly maxima and minima, January-24 October, are from fixed time readings taken at 0700, 1400

 

 

 

 

 

 

 

 

 

 

 

 

 

and 2100 hours. Beginning 25 October 1869, extreme monthly values are from the station's self-registering

 

 

 

 

 

 

 

 

 

 

 

 

 

thermometers. So far as can be determined, no mean cloudiness records were kept at Ft. Snellling during 1869.

 

 

 

 

 

 

 

 

 

 

 

 

 

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

 

 

 

 

 

 

 

 

 

 

 

 

 

NWS 2400 - 2400 HOUR OBSERVATION DAY.

 

 

 

 

 

 

 

 

 

 

 

 

 

High winds or "gales" noted on 2 February, 9 March, 31 March, 14 April, 11-13 May, 16 May, 14 June, 19 July,

 

 

 

 

 

 

 

 

 

 

 

 

 

15 August, 26 August, 5 September, 16 November. Snowstorm on 25 October. Hail storm on 1 August.

 

 

 

 

 

 

 

 

 

 

 

 

 

Last snow of season on 13 April. Ft. Snelling 1869 annual minimum recorded on 4, 6 March.

 

 

 

 

 

 

 

 

 

 

 

 

 

Highest 1869 temperature observed at 1400 hours on 2 July. Minimum of 14 F on 25 October.

 

 

 

 

 

 

 

 

 

 

 

 

 

Greatest daily precipitation recorded on 13-14 September.
