Heavy rain continues across Texas on Saturday, while showers and thunderstorms diminish across the Northeast. A low pressure system over the Northeast pulls further eastward and off the East Coast into the Atlantic Ocean. This will pull a cold front offshore, allowing for showers and thunderstorms to taper off across the Northeast and Mid-Atlantic states. The tail end of this front will linger over the Carolinas and the Southeast, where it will kick up more showers and thunderstorms as it pulls additional moisture and energy in from the Gulf of Mexico.

Meanwhile in Texas, tropical moisture that moved in from the Pacific Ocean combines with an area of low pressure. This will create more heavy rains and flash flooding across most of Texas as the system slowly moves eastward toward the Lower Mississippi River Valley. Expect rainfall totals to reach up to 3 inches, with more in areas of strong thunderstorm development. This will cause more problems with flooding across the region.

Out West, a trough of low pressure over the British Isles pushes a cold front eastward through western Canada. The tail end of this front clips the Pacific Northwest, bringing cooler temperatures with a few rain showers likely in far northwestern Washington. Meanwhile, the rest of the West Coast will remain under a ridge of high pressure, which maintains warm and dry conditions. Expect fire danger to increase across most of California and the Great Basin.
