An active weather pattern will bring major impacts to the central third of the country on Thursday, while a ridge of high pressure builds over the Southeast.
A deep trough of low pressure will move eastward across the Four Corners. Warm and muggy air from the Gulf of Mexico will stream across the Plains and the Midwest. As the aforementioned trough interacts with warm and muggy air, widespread thunderstorms will fire up across the Plains and the Midwest. Severe thunderstorms will be possible over a handful of states, including Texas, Oklahoma, northeast Colorado, Kansas, Nebraska, southeast South Dakota, southern Minnesota, Iowa and Missouri. 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 Texas, southeast Oklahoma, southwest Arkansas, northeast Kansas, southeast Nebraska, southwest Iowa and northwest Missouri. Most of the Mid-Atlantic and the Southeast will stay clear of wet weather as high pressure builds over the western Atlantic.
Meanwhile, daytime heating will trigger showers and isolated thunderstorms across the Intermountain West, the Desert Southwest and the Great Basin. The bulk of these storms will develop during the second half of the day. High elevation snow will be possible in the Sierra Nevada, the Cascades and the Rockies as temperatures remain 5 to 15 degrees below normal.
