Weather Underground Forecast for Monday,June 27,2016

Active weather will impact the Plains on Monday, while monsoonal moisture spreads over the Southwest.

A large area of low pressure will transition quickly eastward over eastern Canada. A pair of cold frontal boundaries will extend southwestward over the Great Lakes, the Mississippi Valley and the Plains. As these frontal boundaries collide with warm and humid air, rain and thunderstorms will fire up over a handful of states. Showers and thunderstorms will be possible in New England, the Mid-Atlantic, the Southeast, the Deep South, the southern Plains and the central Plains. The secondary cold front will initiate strong to severe thunderstorms over the central Plains. Severe thunderstorms will be possible in southwest Nebraska, southeast Wyoming, northeast Colorado and northwest Kansas. 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 south central Kansas and north central Oklahoma.

Meanwhile, a ridge of high pressure will shift over the Four Corners region. This high pressure system will draw monsoonal moisture in from Mexico, which will initiate scattered showers and thunderstorms over parts of the Desert Southwest and the lower Intermountain West. Most areas west of the Continental Divide should stay warm and dry on Monday as high pressure builds over the eastern Pacific.
