DECEMBER. 



December, 1913, was characterized by its mild and comparatively dry 

 weather, and by the fact that the lowest temperature and greatest 

 amounts of snowfall occurred in the extreme southern part of the state. 

 In fact, there were no temperature readings of zero or below over the 

 northern half of the state, except in the extreme northwestern counties, 

 and even there the readings were not as low as in the southern districts. 

 The lowest temperature, — 13°, and the greatest amount of snowfall, 7.6 

 inches, occurred in Taylor County, near the Missouri line. 



The weather during much of the month was unusually pleasant for 

 the time of year, but dense fog prevailed on several days during the 

 morning hours. Somewhat colder weather obtained during the last decade 

 of the month, and most if not all the snowfall of the month occurred 

 at that time. A moderate amount of snow fell in the extreme southern 

 part of the state, but elsewhere the amounts were light, none whatever 

 occurring at numerous stations in the extreme north. There were no 

 severe storms, and the month's wind movement was probably the lightest 

 of record for Decem;ber. Most of the precipitation came during the first 

 week of the month, and light snow flurries occurred between the 20th 

 and the end of the month. There was practically no precipitation be- 

 tween the 7th and the 19th. The amount of precipitation over the state 

 decreased from south to north. Two stations in the north had no pre- 

 cipitation whatever, while Clarinda bad 4.73 inches and Corning had 

 4.70 inches.
