Heavy rainfall and threats of flooding continued from the Desert Southwest into the Central Great Basin on Sunday, while hot weather continued in the upper Midwest and scattered showers persisted in the Southeast.

In the West, Tropical Depression Ivo continues north-northwestward in the eastern Pacific Ocean, just east of Baja California on Sunday and pushed abundant tropical moisture northward over far northwestern Mexico and into the Southwestern U.S.

This translated into periods of widespread and frequent showers with embedded thunderstorms and chances of locally heavy rainfall from parts of inland Southern California and Arizona into southern Nevada, Utah, and Colorado. Flood and flash flood warnings and watches have been issued for the region as the dry surface conditions of the deserts made heavy rainfall more difficult to soak into the ground.

In the Midwest, temperatures continued to heat up across the region as an upper level ridge of high pressure strengthened over the central U.S. Heat advisories remained in effect for portions of the Dakotas through southern Minnesota and Iowa into the nearby western regions of Wisconsin and Illinois.

Daytime highs for the region were expected to reach into the 90s to near the 100 degree mark, while heat indices were expected to reach into the triple digits. Meanwhile, in addition to heat, scattered storms were also possible in the region Sunday afternoon and evening. Areas of central and southern Minnesota and northern Wisconsin were at slight risk of severe thunderstorm development with damaging wind gusts and large hail.


In the Southeast, showers and thunderstorms continued near the Gulf Coast and across Florida through the afternoon. While the strongest of storms in this region remained offshore, a few strong thunderstorms with locally heavy rain triggered flood concerns in northern Florida, southeastern Georgia, and coastal areas of South Carolina.
