Active weather will continue in parts of the East on Monday, while chances of coastal showers persist in the Pacific Northwest and northern California.
In the East, modest moisture along a frontal boundary stalling across the Southeast will support a few areas of scattered showers and thunderstorms to develop in the Southern Plains during the mid- to late-afternoon. The Storm Prediction Center is highlighting a slight risk for severe storms from south-central Kansas into the eastern Texas Panhandle and northeastern Texas. Large to significant sized hail (especially during the afternoon and evening), damaging winds in excess of 60 mph, and isolated tornadoes will be possible within these storms. Later in the evening, these storms will become less severe, turning into primarily a damaging wind threat.
Meanwhile, to the north, a trough of low pressure will build across the northeastern quadrant of the nation through Monday with cool and breezy weather conditions. Dry and gusty winds may create fire weather danger in the Upper Midwest and parts of the northern mid-Atlantic and southern New England. Outside of this area, expect an increasing likelihood of rain and snow showers in areas of northern New England and parts of northeastern Indiana and northwestern Ohio.
In the West, a cutoff low pressure system in the eastern Pacific Ocean and an associated front rotating around the system will maintain chances of showers along the coasts of the Pacific Northwest and northern California. Temperatures in the Lower 48 states Sunday have ranged from a morning low of 6 degrees at West Yellowstone, Mont. to a high of 87 degrees at Phoenix-Mesa Gateway Airpo, Ariz.
