Summary....August 2003 was another month in which central Oklahoma received the majority of its rain in one big burst at the end of the month. Much of the state recorded significant rainfall the final three days of the month. Rainfall totals exceeding 8 inches were confirmed in Grant County in northern Oklahoma, and radar estimated totals over 10 inches in parts of Grant County and also Okmulgee County (south of Tulsa).

Turlock CA had its wettest August in decades. A total of .33 inch fell in Turlock in Aug 2003, a whopping 3105 percent of the 16-yr average! Turlock had rain on three days - .19 inch on the 2nd, .09 inch on the 21st, and .05 inch on the 26th. The .19 inch total on the 2nd was greater than the total rainfall which had occurred in the previous 16 August combined! To give an idea of how uncommon rainfall is in August, here is a complete list of all of the measurable rainfall which occurred in Turlock in August between 1987 and 2002....

8/21/1988     .01 inch
8/13/1991     .03 inch
8/20/1997     .04 inch
8/29/2000     .02 inch
8/31/2000     .07 inch

Although rare, this type of rainfall is not completely without precedent. Turlock received .52 inch in Aug 1965, .55 inch in Aug 1975, and .35 inch in Aug 1976. If radar estimates are to be believed, the thunderstorm which struck parts of Stanislaus and Merced Counties on the 2nd was historic. Turlock received the fringe of this storm and got .19 inch, but radar estimated in excess of .50 inch west of Turlock and over 1.00 inch east of Newman. Unfortunately these areas are sparsely populated so we'll never know if these amounts verified.
