REMARKS --- |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Unless otherwise noted, all 1867 data are from fixed time observations taken daily at the Ft. Snelling |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
post hospital station at 0700, 1400 and 2100 hours local time. So far as can be determined, the station was |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
not equipped with self-registering maximum-minimum thermometers at any time during 1867. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Average monthly temperatures were calculated by taking the sum of the daily 0700 hour and 1400 hour readings |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
plus twice the sum of the 2100 hour readings and dividing the resulting sum by four. Ft. Snelling station re-established |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
on 1 April 1867 (Station previously closed when fort was temporarily decommissioned in April 1858: extant evidence |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
indicates, however, that unofficial records were maintained at the fort site during some portion of the intervening period. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
So far as can be determined, any such records have been lost / destroyed). |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Extreme maxima and extreme minima are the highest and lowest values OBSERVED at the Ft. Snelling station |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
during the month indicated. Monthly average temperatures have NOT been adjusted to the NWS 2400-2400 hour |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
observation day. Highest 1867 observed temperature was recorded at 1400 hours on 7 August. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Monthly mean force of wind values are the averages of visual air movement observations taken daily at 0700, |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
1400 and 2100 hours local time. So far as can be determined, wind force values were obtained from the Beaufort scale |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
(or a modified Beaufort scale adapted for Army use). Greatest daily precipitation recorded on 15 September. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Force 8 winds at 1400 hours on 1 May. 1.75 inches of rain on 2 June. "Slight frost" noted on 27-28 August. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
"Snowstorm" on 29 October. 60 F at 1400 hours on 22 November. |
