US Hazards

Thunderstorms Tuesday from Southeast Texas into the Lower Mississippi Valley
A stationary front near the Gulf Coast will serve as a focus for shower and thunderstorm activity on Tuesday as an upper level system moves across the region. Southerly winds will bring warm moist air northward, and instability should be sufficient for the development of thunderstorms by midday. Some of these storms are expected to become severe with  damaging winds and an isolated tornado or two will be the the primary hazards. Activity is forecast to develop in east Texas initially and move into Louisiana and Mississippi throughout the day.

Excessive Rainfall from Northeast Texas into the Southeast Tuesday and Wednesday
There will be a threat for heavy rainfall from northeastern Texas into the Southeast Tuesday into Wednesday. An upper level system will aid in the development of an area of low pressure along the front later in the day. The front will become a warm front to the east of the low and moist air will be moving northward. Rainfall will begin along and north of the warm front, continuing into the overnight hours. Rain will spread into the Carolinas on Wednesday. Two day rainfall totals of 2-4 inches with locally higher amounts in excess of 5 inches are forecast. Flash flooding may become a concern as early as Tuesday evening.
