Wet weather with threats of flooding will continue in the Desert Southwest into the Central Great Basin on Tuesday, while hot weather and chances of severe weather persist in the Midwest.
In the West, frequent scattered showers with embedded thunderstorms and chances of locally heavy rainfall will continue from parts of inland southern California and Arizona into the Central Great Basin. Flood and flash flood warnings and watches are expected to remain in effect for the region through the evening. Burn areas from recent fires will remain especially prone to flash flooding and debris flow.
In the Central U.S., hot temperatures will continue in the Northern Plains into the Upper Midwest as a ridge of high pressure remains dominant over the Central U.S. Heat advisories will continue for portions of the Northern Plains and upper Midwest as daytime highs climb well into the 90s to near the 100 degree mark and heat indices range from about 100-105 degrees with locally higher values. Meanwhile, strong heating will help fuel thunderstorms in the Midwest and parts of the Northeast through the afternoon and evenings. Areas of the Great Lakes into the Ohio Valley are at slight risk of severe thunderstorms development with locally damaging wind gusts and hail.
Elsewhere, expect chances of showers and thunderstorms to persist in parts of southern Texas and Florida.
