Weather Underground Forecast for Monday, August 26, 2013.
Wet weather and possible flooding will continue from the Desert Southwest into the Central Great Basin on Monday, while hot weather continues in the Central U.S, and scattered showers persist in the Southeast.
In the West, intense rainfall from parts of inland southern California and Arizona into southern Nevada, Utah, and Colorado will lighten on Monday as Tropical Depression Ivo continues weaken in the eastern Pacific Ocean. Tropical moisture spreading inland across these areas will result in scattered showers with embedded thunderstorms and chances of locally heavy rainfall possible in Arizona and Utah. Flooding and flash flood concerns will persist.
In the Central U.S., hot temperatures will continue to heat up across the Midwest as an upper level ridge of high pressure over the Central U.S. shifts to the east. Heat advisories will remain in effect for portions of the upper Midwest as daytime highs climb into the 90s to near the 100 degree mark and heat indices reach into the triple digits. Meanwhile, in addition to heat, a cold front extending across the northern tier of the region will kick up scattered storms in parts of the upper Mississippi Valley and the upper Great Lakes. Parts of the Dakotas into the central Wisconsin are at slight risk of severe thunderstorm development with damaging wind gusts and large hail.
Further east, an associated warm front will kick up showers in the Northeast as it treks toward the East Coast. To the south, expect showers and thunderstorms to continue near the Gulf Coast and across Florida.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of 37 degrees at Stanley, Idaho to a high of 99 degrees at Hugo, Okla.
