The nation’s weather

Weather Underground Forecast for Sunday, August 04, 2013.

Wet weather will diminish for the Eastern states on Sunday, while showers and thunderstorms will persist across the Plains. A low pressure system continues strengthening as it moves off the Central Rockies and into the Plains. This system will create a warm front that extends eastward, bringing strong storms to the Southern and Central Plains. These storms have a history of turning severe with strong winds and large hail. Thus, expect areas of strong storms to develop. At the same time, a trough of low pressure moves in from the north, pushing scattered showers into the Northern Plains and Upper Midwest. Heavy rainfall and strong storms are not expected in these areas.

In the East, a cold front moves offshore and allows for high pressure to build across the Eastern states. This will push moisture away to the south and east, allowing for dry and pleasant conditions to spread throughout the region. However, the tail end of the cold front lingers over the Southeast, maintaining chances of scattered showers and thunderstorms to develop from the Lower Mississippi River Valley through northern Florida.

Out West, monsoonal moisture remains limited over the Four Corners, which will decrease chances of storms over the region on Sunday. Meanwhile, the West Coast will see little change in weather as a trough of low pressure offshore maintains onshore flow, keeping coastal areas cool and cloudy, while inland areas will see another hot and sunny day.

Temperatures in the Lower 48 states Saturday have ranged from a morning low of 28 degrees at Stanley, Idaho to a high of 102 degrees at Phoenix, Ariz.
