The remnants of Hurricane Dolly were dumping heavy rain over southern Texas on Thursday, a day after making landfall, then weakening to a tropical storm. Flooding concerns persisted as Dolly crept across the state.

A low pressure system over the Northeast was expected to produce a stationary front sagging along the East Coast and into the Southeast, causing showers and thunderstorms. Flooding was likely to be a concern, and severe weather, including hail, strong winds, heavy rain and tornadoes, was possible.

Another low pressure system that developed off the eastern Rockies was hovering over the northern and central Plains. As a result, showers and thunderstorms were forecast across the upper and mid-Mississippi valleys.

The West Coast was expected to remain dry with mostly sunny skies, while the Southwest could see a break in monsoon showers and thunderstorms.

Temperatures in the Lower 48 states on Wednesday ranged from a low of 35 degrees at Stanley, Idaho, to a high of 118 degrees at Death Valley, Calif.
