Wind. — South winds prevailed. The highest velocity reported was 46 

 miles per hour from the north, at Sioux City, Woodbury County, on the 

 27th. 



NOVEMBER. 



There was a great contrast between the weather in November, 1909, 

 and November, 1910. Last year both the temperature and precipitation 

 were decidely above the normal which was unprecedented; the average 

 temperature being 6.5° above and the average precipitation, 4.00 inches 

 above the normal. The snowfall was also much above the normal, the 

 monthly amounts ranged from 8 to 29.5 inches. The heavy rains caused 

 high stages in all streams and rivers and much of the bottom lands 

 were flooded and the heavy snow prevented the harvesting of about 35 

 per cent of the corn crop. 



The weather during November, 1910, was, on the whole, very pleasant 

 and exceptionally favorable for outdoor work, the temperature and the 

 precipitation both being below the normal. The deficinecy of tempera- 

 ture was, however, due to uniformly low maxima rather than to abnor- 

 mally low minimum temperatures. In fact, the minimum tmperatures 

 were above the normal and while there were several days on which mod- 

 erately low temperature prevailed in some parts of the state, the first 

 general cold wave of the season did not occur until the last day of the 

 month. 



The precipitation was much below the normal at all stations except 

 at Cumberland, Cass County, where there was a slight excess due to a 

 heavy shower of rain on the 4th when 1.02 inches fell. The average 

 snowfall was also much below the normal and 18 of the 121 reporting 

 stations did not have even a trace of snow during the month. 



Owing to the dry weather, rapid progress was made in gathering the 

 corn crop and at the end of the month about 90 per cent of the crop had 

 been harvested and the corn was in unusually good condition. Dry 

 weather has not been favorable for pasturage and fall grain and the 

 latter is not in as good condition as it was at the close of November, 1909. 



All streams and shallow wells are abnormally low and the scarcity 

 of water is becoming serious in many sections. Press dispatches indicate 

 that several railroads are experiencing considerable trouble in supplying 

 their engines with water. Some of the reservoirs along the line of the 

 Burlington road are dry or nearly so, and many trains have been carry- 

 ing two tenders with which to supply the water, one being entirely in- 

 adequate where such a great distance has to be covered between the water 

 stations. The Iowa Central railroad has also experienced considerable 

 trouble, engines are barely able to make terminals for water, the supply 

 in the smaller towns along the line having become exhausted. This is 

 especially true over the southeastern divisions of the road. 



Temperatube. — The monthly mean temperature for the state, as shown 

 by the records of 113 stations, was 33.°, which is 2.5° below the normal 

 for Iowa. By sections the mean temperatures were as follows: Nor-
