 MARCH. 



March 1911, prior to the 26th, was very pleasant, the temporature be- 

 ing considerably above the normal with very little precipitation. After 

 the 26th, lower temperatures prevailed and snow storms were frequent. 

 For the month as a whole the average temperature was 5.4° above and the 

 precipitation 0.99 inch below the normal, making it the driest March, with 

 two exceptions, on record since state-wide observations began. The 20th 

 and 21st were the warmest days, when the maximum temperatures ranged 

 from 70° in the northern to 80° at a few stations in the southern districts^ 

 The lowest temperature was recorded generally between the 15th and 

 18th, but at a few stations the minimum was recorded on the 1st or the 

 27th. 



The most notable characteristics of the month were the high wind move- 

 ment and the severe dust storms that prevailed in the northwestern coun- 

 ties, on the 24th and 29th.
