Moderate Flooding Risk for Central and Southern Indiana as Heavy Rain Returns
A Moderate Risk for excessive rainfall is in place across parts of central and southern Indiana, where additional heavy rain could worsen flooding from yesterday. Storms moving from Iowa and Illinois may bring rainfall rates of 2–3 inches per hour, with flash flooding possible. Another round of storms tonight into early Friday could repeatedly track over the same areas, increasing the risk for more serious flooding, especially where soils remain saturated. Heavy thunderstorms are also possible from Iowa into Kentucky, with localized flooding concerns. Across the High Plains, storms from Colorado to Montana could produce heavy rain and flash flooding, particularly in northeast Colorado and northwest Kansas. The Southwest, especially Nevada and Utah, also faces a risk of isolated to scattered flash flooding from thunderstorms.

Widespread Western Storms Bring Fire Weather Concerns to the Southern Plains
Showers and thunderstorms will develop across much of the western U.S. today as monsoon moisture, daytime heating, and an upper-level trough fuel storm activity. Some storms in northern California, Oregon, Idaho and Montana may produce little rain while still generating lightning, creating a risk for new wildfires in dry areas. In the Southern Plains, hot temperatures near 100 degrees, very dry conditions and gusty south winds will create elevated fire danger across the Texas Panhandle, western Oklahoma and southern Kansas. Winds could reach 15–20 mph, while humidity falls into the lower teens. High-based thunderstorms may also develop this afternoon, producing strong wind gusts and lightning. Any lightning-caused fires could spread quickly due to the hot, dry and windy conditions.
