The country's main weather feature Sunday is a storm rolling from the Western plains over and into the Tennessee Valley, followed by another storm behind it.
All of this activity will produce thunderstorms and rain in the Mississippi Valley and Tennessee Valley. In the Plains, more rain is expected in the Dakotas, potentially bad news for the flooded town of Minot, N.D. This excess rain will add water to the already raging Souris River though no strong tornadoes are anticipated from the stormy weather.
The Southern plains will not receive any rain Sunday, prolonging a devastating drought that has spread from Arizona through Louisiana.
In the West, a high pressure system will dominate for one more day before an unseasonably strong storm from the Pacific Ocean begins to weaken the high pressure system to open the work week. Warm inland temperatures will give way to cool and cloudy conditions closer to the coast in California, while typical warm desert temperatures will prevail in the Southwest.
Temperatures in the Northeast will rise into the 70s and 80s, while the Southeast will see readings in the 90s and 100s. The Southern plains will continue with warm temperatures in the 90s and 100s, while the Southwest will see similar conditions. The Northwest will rise into the 70s and some 80s. Temperatures in the Lower 48 states ranged Saturday from a morning low of 26 degrees at Stanley, Idaho, to a high of 111 degrees at Pecos, Texas.
