General thunderstorms and isolated strong wind gusts are possible Thursday for portions of the Central Plains, Southeast, and Carolinas. For the Northern Plains, strong to severe thunderstorms with hail and damaging winds possible. Across the Desert Southwest, heavy rain and flooding are possible.
The frontal boundary advancing off the east coast will continue to push further south and east with additional showers thunderstorms possible through the Central Gulf of Mexico as well as in Southern Florida and Central Texas. Severe weather is not anticipated at this time. Into the Mississippi Valley and Ozarks, additional showers and thunderstorms will be possible as a shortwave trough provides additional atmospheric lift during the afternoon. While severe weather is not anticipated with these storms, isolated stronger activity could occur with the main threats remaining brief wind gusts over 40 mph and small hail.
Further west, a frontal boundary will begin to progress out of the Northern Plains with a slight risk for afternoon shower and thunderstorm development. While widespread activity is not anticipated at this time, a few stronger storms could produce locally heavy rainfall, damaging wind gusts and isolated hail.
In addition, a deepening area of low pressure will continue to dig southward in the Western US before advancing eastward late in the week. General showers and thunderstorms will be possible through the Great Basin as well as into the Pacific Northwest.
As remnants of Tropical Depression Odile continue to lift northward into the Desert Southwest, additional showers and thunderstorms will be possible once again through the region. While accumulations are anticipated to remain under 3 inches, additional rainfall in the region will create conditions favorable for flooding.
