A very moist air mass along with an upper-level disturbance and an approach of a surface frontal boundary will bring about the potential for heavy rainfall that may lead to localized flash flooding through Saturday Night. Forecast rainfall amounts are between 1/2 and 1 inch. The reasonably highest rainfall amounts are roughly between 1 and 4 inches. Remember there is a 10 percent chance that these rainfall amounts may be even higher. If these rainfall amounts fall in a short period of time or over the same location for a prolonged period of the time, the risk for flash flooding will increase.
