Weather Underground Forecast for Friday, April 15, 2016

A trough of low pressure will shift across the Intermountain West on Friday, while a stationary front lingers over the Gulf Coast.

An area of low pressure will move slowly eastward across the Intermountain West and the Plains. This system will generate moderate to heavy snow across the higher elevations of the Rockies, while a mixture of rain and snow affects the northern and central high Plains. Winter storm warnings are in place across Utah and Colorado in anticipation of heavy snow. A cold frontal boundary associated with this system will collide with a warm air mass over the Plains. This interaction will generate strong to severe thunderstorms over several states. Severe thunderstorms will be possible in southwest Nebraska, eastern Colorado, western Kansas, western Oklahoma, northwest Texas and northeast New Mexico. 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 South Dakota, western Nebraska, northwest Kansas and northeast Colorado.

Meanwhile, a stationary front will be the focal point for showers and thunderstorms along the Gulf Coast. These storms will develop from the lower Mississippi Valley to the southern Mid-Atlantic on Friday.

Out west, a strong wind event will impact the Southwest. Wind gusts of 50 to 60 mph will be possible across portions of southern California on Friday. High wind warnings are in effect over the region.
