🌎 Regional Forecast – Where It Will Rain the Most
Southern U.S. (Texas, Louisiana, Mississippi, Alabama)
A major rain corridor will strike the Gulf Coast and lower Mississippi Valley. Cities like Houston, Baton Rouge, and New Orleans are facing intense rainfall from early morning into the evening. Downpours may exceed 100 mm and could lead to flash flooding. Thunderstorms are also likely, especially during the late morning to afternoon hours.
Central Plains (Oklahoma, Arkansas, Missouri)
Expect modera to heavy rainfall between late morning and early evening. Precipitation totals may reach 30–80 mm. Road conditions may worsen, and isolated thunderstorm activity is possible.
Northeast (New York, Pennsylvania, New England)
Moisture-laden air from the south will surge into the region by afternoon and evening. Rain will intensify through the evening hours with possible embedded thunderstorms. While totals are lower than the South, urban flooding in areas like New York City is not out of the question.
