The number of days with the heaviest precipitation is not projected to change dramatically. The historical (1971-2000) distribution of the greatest 2% of daily precipitation (Top: about seven days each year) echoes the regional east-west gradient in average precipitation. By mid-century (2041-2070), the projected change in days exceeding those precipitation amounts remains greatest in the northern area for both the lower emissions scenario (B1) and for the higher emissions scenario (A2).
