Table 14.— Beginning, ending, and duration of each normally dry period and of longest 

 normally rainy period within the period of the average frostless season. (Plates 50 

 and 51.) 



A normally "dry period" begins on the last day of the first 5-day period whose average normal 

 daily precipitation is not over 0.10 inch; a normally "rainy period" begins on the last day 

 of the first 5-day period whose average normal daily precipitation is greater than 0.10 inch. 

 Months are represented by Roman and days of the month by Arabic numerals; numbers 

 in parentheses are the duration of the respective periods, in days, these being in full-face type 

 for the longest dry period in each case.
