Discussion: By this afternoon, severe thunderstorms align across central Texas eastward to Louisiana with tornado risk for late day and evening in northeast Texas and northwest Louisiana (Fig. 1). Flash flooding is already taking place in northern Louisiana and will worsen today (Fig. 2). On Wednesday, the peak intensity of this storm is realized. A large mass of severe thunderstorms is projected across much of the Northern Gulf States with tornado risk from Louisiana to Alabama (Fig. 3). Excessive rain and attendant flooding strike the entire Southeast U.S. centered on Alabama (Fig. 4). On Thursday, the severe weather risk remains although not as intense (Fig. 5). As the storm moves into the East, a southerly gale develops on the East Coast causing coastal flooding to already higher than normal sea level. Excessive rainfall stretches along the Appalachian Spine on Thursday (Fig. 6). A windswept rain moves across the Northeast on Friday. Expect a widening flood risk area over the next 2-3 days (Fig. 7) including coastal communities on the Atlantic Seaboard.
