The nations weather

The South-Central US was expected to continue to be hot and humid on Saturday, while the central states will see plenty area of active weather. A ridge of high pressure over the southeastern states was expected to slightly shift to the west, but produce temperatures over 100 degrees for the Southern Plains and the South. Heat indices between 110-120 for the Lower Mississippi Valley and Southeast were expected. Meanwhile, a frontal boundary was expected to push through the Tennessee Valley and Mid-Atlantic kicking up rain showers and thunderstorms. In addition, the remnants of Emily off the eastern coast of Florida were expected to contribute to showers over parts of Florida.

To the north, an area of low pressure spinning over the Ohio River Valley was expected to bring moderate to light showers and thunderstorms to the region and Great Lakes. However, high pressure off the coast of New England was expected to produce mostly sunny and dry conditions for the extreme Northeast.

In the Central US, a low pressure system was forecast to move eastward off the Rockies into the Northern Plains producing widespread areas of showers and possible severe thunderstorms across the Northern and Central Plains. Heavy downpours and strong winds were likely to be associated with these storms, with flash flooding possible across the North Central US.

To the west, monsoonal moisture was expected to persist in the Southwest triggering scattered showers over the Four Corners region. At the same time, low pressure spinning over Canada was expected to push light showers and clouds to the northwestern states. Meanwhile, the West Coast was expected to be mostly sunny, with low clouds on the coasts during the morning hours. Temperatures in the Lower 48 states Friday have ranged from a morning low of 32 degrees at Truckee-Tahoe, Calif. to a high of 111 degrees at Cushing, Okla.
