The nation's weather

The stubborn stationary front of the East will finally move Monday as a wave of low pressure from the West moves into northern Texas and Oklahoma.

This will drive the western portion of this front northward through the Ohio Valley toward the Great Lakes as a warm front. This will translate into widely scattered rain showers and thunderstorms. Periods of heavy rainfall are expected from the Mid-Mississippi Valley through the Ohio Valley. The Storm Prediction Center has issued a moderate chance of severe weather from Arkansas into southern Missouri due to ample moisture spreading through the region. The center has also issued a slight risk of severe weather from the eastern Southern Plains to the Mid-South and Mid-Mississippi, Lower Tennessee and Lower Ohio Valleys. These storms may produce hail, damaging wind and a few tornadoes. Residents in these areas should monitor local weather conditions closely through the day and take proper precautions against severe weather.

Meanwhile, in the West, a wave of low pressure will move through the Great Basin with scattered rain showers, high elevation snow and thunderstorms. Another Pacific disturbance will approach the northern California and Pacific Northwest coasts with scattered rain and high elevation snow showers.

Temperatures in the Lower 48 states Sunday ranged from a morning low of 8 degrees at Stanley, Idaho, to a high of 95 degrees at Falfurrias, Texas.
