For a period of 4-14 days (2d6+2) the usual principles governing frequency and amount of precipitation do not apply. On the first day of a drought no precipitation will fall, regardless of what the Day-To-Day Change Table has indicated. At any time when trace precipitation is indicated, no rainfall or snowfall will occur. In an area where light or moderate precipitation is the normal maximum, no precipitation greater than a trace amount will fall, and this will occur no more than once every span of five full days. In addition, and trace result is disregarded. In an area where heavyprecipitation is the normal maximum, treat any precipitation result as two steps lower than actual, so ‘H’ becomes ‘L’, ‘M’ becomes ‘T’, and ‘L’ becomes no precipitation. Use the Day-To-Day Change Table normally for temperature and wind, but amend any precipitation results as described above.
