(AP) -- Storms raked the Pacific Northwest, eastern Great Lakes and Northeast early Monday, while thunderclouds swirled over Texas and mild temperatures held in the Southeast.

Scattered rain showers and isolated thunderstorms were forecast across the Great Lakes, Northeast and portions of the northern mid-Atlantic region.

High pressure was to keep skies mostly clear across the southern Ohio Valley, much of the Tennessee Valley, the remainder of the mid-Atlantic region, the Southeast and Florida.

The greatest threat for severe thunderstorms was across Texas, where a low pressure system slowly gliding across the southern U.S. was to bring another day of wet weather gusty winds and hail.

A Pacific storm was forecast to slam into the California and Oregon coast, bringing moderate to heavy rain north of Southern California.

Highs will be in the mid 40s to upper 60s across the Northeast, and the upper 50s to low 80s in the mid-Atlantic states; the upper 60s to upper 70s in the southern Plains; and the 40s to lower 60s for the Pacific Northwest.

Temperatures in the Lower 48 states on Sunday ranged from a low of 10 degrees at Presque Isle, Maine, to a high of 95 degrees at Death Valley, California.
