RURAL NEW YORK 



The mean summer precipitation is shown in Fig. 

 13. The winter precipitation falls largel}' as snow. 

 The regions of high precipitation are in the main 

 those of low winter temperature. Long Island and 

 the lower Hudson Valley are an exception to the rule.

Local storms and thundershowers develop most fre- 

 quently on the western half of the southern plateau 

 and on the western flank of the Adirondack Moun- 

 tains. They travel eastward, a little more rapidly 

 through the Mohawk Valley regions than over the 

 uplands. The hour of the loudest thunder which is 

 synonymous with the most violent electrical disturb- 

 ance is about two or three o'clock in the afternoon
