Remarks. 



The weather for Massachusetts for August, 1890, has dif- 

 fered but little from the month in other years. There was a 

 slight deficiency in temperature, sunshine and precipitation, 

 though there was no strongly marked departure from the 

 normal in either element. The precipitation was somewhat 

 unevenly distributed, and some localities had an amount 

 above the normal, but the general average was below. 



The weather was influenced by the passage of eight 

 cyclonic areas and eight anti-cyclonic ones. During the 

 passage of the first cyclone down the St. Lawrence, on the 

 4th-6th, the warm southerly winds carried the temperature 

 to the maximum for the month, varying from 80° to 94°. 

 The high winds and hail on the 10th, which did damage in 

 Connecticut by beating down corn and tobacco, occurred 

 with the change of the wind to westerly, after the passage 

 of the second cyclone. The low temperature and cloudy, 

 threatening weather along the coast on the 12th was prob- 

 ably due to the influence of the West India cyclone, which 

 was far out to sea. Temperature minima occurred in dif- 

 ferent localities on the 16th, 19th or 25th, under clear anti- 

 cyclonic skies. The tornado-like disturbance in western 

 Massachusetts on the 19th was due to the influence of the 

 fifth cyclone, which moved rapidly across New England from 

 south-west to north-east. On the 22d a secondary formed on 

 the southern coast and rnoved down the coast on the 23d and 

 24th, causing heavy rains. On the 27th a cyclonic area 

 moved across New England, from west to east, with rapidly 

 increasing energy, and gave high winds and rain. Some 

 damage was done to crops and light coast vessels by wind 

 on that date.
