The Gulf Coast system will arrive Sunday. More than 15 million people from Lake Charles, Louisiana to Pensacola, Florida, and northward to Memphis could experience damaging winds, hail and a few tornadoes.
Flash flooding will also be a concern, especially for areas of Texas and Louisiana that have been dealing with heavy rain for the past few days.
“The ground is already saturated in a lot of these areas, so it wont take much to initiate flash flooding,” said Haley Brink, CNN Meteorologist. “In fact, some areas of Texas have picked up over 4 inches of rain in just the last 48 hours”.
Severe storms and snow?
A second system will be sliding through the Mountain West and Central Plains on Sunday.
By Sunday night, as colder air pushes in behind the front, snow is forecast for the higher elevations of Colorado and Wyoming.
Several cities along the Front Range of the Rocky Mountains will go from having temperatures 15-20 degrees above normal to 20-25 degrees below normal in just 48 hours.
Denver will be one of those cities feeling seasonal whiplash. On Saturday, the mile-high city reached 86 degrees — their average high for late June. By Monday, the city will be expecting a high temperature of only 47 degrees — their normal high for late February.
The exceptionally warm air ahead of the front will be fueling yet another day of severe storms — this time along the Mississippi River Valley region.
On Monday, over 40 million people from Dallas, Texas, to Columbus, Ohio, will be under the threat for severe storms. The main dangers will be damaging winds hail, and tornadoes.
The greatest threat for tornadoes exists from Tulsa, Oklahoma over to Paducah, Kentucky.
