Weather Underground Forecast for Monday, May 06, 2013.
Wet weather will continue for the Southeast on Monday, while chances of showers and thunderstorms spread across the West Coast States.
In the East, a slow moving upper low will linger over the Southeast, maintaining areas of heavy rain. The system will pull moisture inland, while an associated cold front moves toward the Southeast coast and associated waves of energy lift northward. As this system advances, heavy rainfall will spread across Lower Ohio Valley into the eastern Tennessee Valley and parts of the Carolinas and Virginias, while more moderate showers fall across the Southeast. While severe thunderstorms are not anticipated with this system, heavy rainfall will continue to create chances of flooding across the region.
In the West, a closed low will advance across northern California, bringing scattered showers and thunderstorms to northern California, the Sierra Nevada, and the southern and central California coast and valleys. Additional precipitation may also become possible over the Cascades of the Pacific Northwest. Elsewhere in the West, upper level energy will advance eastward across the Four Corners, stirring up isolated areas of showers and high elevation snow.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of 21 degrees at Chadron, Neb. to a high of 87 degrees at Phoenix-Mesa Gateway Airpo, Ariz.
