Meanwhile, a low pressure system off the Pacific Northwest coast will move slowly toward the coast Thursday, ushering moisture into Washington and Oregon. This moisture will translate to rain throughout these states, accompanied by breezy weather, especially over higher elevations.
Tropical moisture in the western Gulf of Mexico will stream toward the Gulf Coast and instigate rain and thunderstorms along the Texas and Louisiana coasts mainly in the afternoon and evening.
A low pressure trough will just pass through the Northeast, but only scattered areas of showers will be possible from New York through Maine. This trough will also bring cooler air into the region.
Elsewhere, scattered showers will be possible in the Northern Plains and Northern Rockies, but will not be widespread in nature.
The Northeast will rise into the 70s, while the Southeast will see temperatures in the 80s and 90s. The Plains will rise into the 90s and 100s, while the Southwest will see similar temperatures. The Northwest will rise into the 70s and 80s.
