weather was remarkably warm from the 1st to the 9th, and moderately 

 warm from the 16th to the 23d, and from the 26th to the close of the 

 month. The highest temperature was recorded at most stations on the 

 4th. The coldest period was between the 9th and 16th, the lowest tem- 

 perature being recorded on the 15th. Another cold period occurred on the 

 24th and 25th. 



The average precipitation was generally above the normal, there being 

 only 29 out of 106 stations that reported a definciency. For the State as a 

 whole, the daily amounts of precipitation were not very large, but rain 

 or snow was frequent. There were but two days between the 5th and 27th 

 on which rain or snow did not fall at some station in the State. The 

 worst storm of the month was on the 9th, when the second severe blizzard 

 of the winter occurred. This storm was especially severe in the north- 

 western counties where the snowfall was heavy and the wind velocity was 

 over 50 miles per hour. The snow drifted badly and caused a complete 

 suspension of all railroad and street car traffic. Many deep snow drifts, 

 caused by this storm, were still visible in the northern counties at the 

 close of the month. 



Another storm with blizzard characteristics occurred on the 14th but 

 was not heavy enough to cause much damage except to again fill up the 

 narrow cuts which had been shoveled through the drifts caused by the 

 previous storm. Some damage has been done to fall grains, clover and 

 alfalfa by the alternating thawing and freezing weather.
