Heavy rains continued in the Deep South on Sunday as a low pressure system moved eastward from Texas to the Louisiana coast and an associated warm front extended through the Central Gulf Coast States. The system pulled in additional moisture from the Gulf of Mexico, fueling another round of showers, periods of heavy rainfall, and strong thunderstorms from eastern Texas and Oklahoma through the Central Gulf Coast States. Excessive rainfall in already saturated areas maintained chances of flooding and flash flooding as rainfall totals ranged from 2 to 5 inches this afternoon. In addition to precipitation, there was a slight risk of severe thunderstorms with strong to damaging wind and tornadoes in the Lower Mississippi Valley and the Central Gulf Coast.

Meanwhile to the north, a second low pressure system remained the dominant weather feature of the Northeast on Sunday. The system continued to pull moisture from the Atlantic Ocean inland as it trekked northeastward across Maine. This translated into more widespread showers in Maine and light scattered showers across the Northeast.

Out West, a ridge of high pressure over the West Coast prevailed across much of the West with warm to hot temperatures and generally fair skies. Well above average temperatures in the inland valleys of southern California combined with dry conditions kept fire danger high.
