United States Overview:

Hot weather to continue from the Northwest into the Plains, some relief by Wednesday for the Northeast. Heavy Rain and Flash Flooding threat from the Ohio Valley into the Central Appalachians and along the Gulf Coast. Monsoonal Showers to continue from the Southwest, portions of California, the Great Basin and into the Intermountain West.

A mesoscale convective system (organized thunderstorms) produced heavy showers and thunderstorms in the desert, mountains and even to the coast near San Diego. San Felipe received 2.49”, Ranchita 2.27”, and Mason Valley 1.84”. Flash flooding occurred all around Borrego Valley, Desert Research Institute, Airport, Coyote Canyon and adjacent citrus tree fields. This system also produced a dust storm (haboob) in the Imperial Valley, Salton Sea and Borrego desert, dropping visibility as low as one half mile. Wind gusts were 40 to 50 mph, with a top gust of 57 mph at Big Black Mountain near Lake Henshaw. This was followed by hours of lightning.
