A weak tropical system will bring showers and thunderstorms Tuesday across coastal and central Texas as well as parts of Louisiana. Rainfall is expected to range between 4 and 8 inches, with 8 to 16 inches in some spots. This may result in significant flooding in low-lying and urban areas.

Showers and thunderstorms will extend from the northern Rockies to the central Plains, parts of the Ohio Valley, the central Appalachians and the Middle Atlantic coast. Heavy rain will fall along the boundary between hot, humid air to the south and west and cool, dry air to the north and east. This may result in urban and small-stream flooding.

Much of the Southeast will remain hazy, hot and humid, with very spotty afternoon and evening thunderstorms. While the northern Plains, the upper Great Lakes and New England will remain warm and sunny, it will be much cooler than Monday.

West of the Rockies, most areas can expect dry weather and sunshine. Seasonable heat is in the forecast for the interior Southwest. A breeze will cool the coast of California. Warmth will build to record levels in parts of Washington and Oregon.

FOCUS: Heavy Rain and Flooding in Texas

Tropical moisture will continue to flow across parts of southeastern Texas and western Louisiana through Thursday. This will result in widespread, heavy rain. Total rainfall may exceed a foot in some spots.
