A stormy weather pattern will impact the southern tier of the country on Thursday, while a frontal system makes its way across the Northwest.
A trough of low pressure will move slowly eastward over the southern Plains. This system will draw moisture from the Gulf of Mexico, which will fuel heavy rain and thunderstorms across the southern edge of the country. Severe thunderstorms will be possible in southeast Texas and southwest Louisiana. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. In addition, heavy rain will bring threats of flash flooding to central Texas, eastern Texas, Louisiana, southern Arkansas and western Mississippi. Scattered showers and isolated thunderstorms will also be possible across the central and southern Rockies. The highest elevations of the central Rockies will experience mixed precipitation.
Meanwhile, the tail end of a cold front will produce showers and thunderstorms over the southern Mid-Atlantic and the Southeast. Isolated thunderstorms are also expected for the northern Mid-Atlantic and New England.
Out west, a cold frontal boundary will stretch from the northern high Plains to central California. This frontal system will bring chances of showers, thunderstorms and high elevation snow to the Pacific Northwest, northern California, the Great Basin and the upper Intermountain West.
