The Nation's Weather 09.08.09

By WEATHER UNDERGROUND (AP)

Several weather disturbances were forecast to produce areas of active weather across the nation Tuesday.

An area of low pressure located off the North Carolina coast would continue to produce disorganized thunderstorms as it lifted northward along the Mid-Atlantic shoreline. Locally heavy rainfall and strong, gusty northeast winds would persist across the nearby coastal regions of the North Carolina and Virginia coasts throughout the day. Strong winds would create a high risk for rip currents, while forecasters said excessive rainfall may yield to areas of coastal flooding.

Meanwhile, low pressure moving through the Ohio Valley was expected to continue to produce areas of scattered showers and thunderstorms across the Eastern Valleys during the next couple of days. Energy from the system would also spread into the eastern Great Lakes, triggering areas of light showers and isolated thunderstorms.

In the Central U.S., a frontal boundary sweeping through the Northern Plains was expected to trigger a batch of locally heavy precipitation and thunderstorms throughout the day. Forecasters said some of these thunderstorms may turn severe during the afternoon and evening.

Elsewhere, scattered thunderstorms and another round of heavy rainfall may produce localized flooding along areas of the central Gulf Coast, forecasters said. Fairly tranquil weather was expected throughout the majority of the West.

Temperatures in the Lower 48 states Monday ranged from a low of 28 degrees at Stanley, Idaho, to a high of 109 degrees at Death Valley, Calif.
