Violent weather expected to tear through Central U.S. again this weekend

WASHINGTON, May 9 (UPI) -- Severe weather expected to produce dangerous tornadoes and oversized hail will batter central states Mother's Day weekend.

Two large, conflicting weather systems will collide over the area Saturday.

A giant mass of warm, humid air lifted from the Gulf of Mexico is heading straight into a system of cold, dry air from the northwest.

The unfortunate meeting of the two systems creates the perfect conditions for large, long-lasting tornadoes and even flash floods. The risk of severe thunderstorms is highest from the Central High Plains into parts of Texas, according to forecasts from the National Weather Service.

A tornado watch was issued Saturday afternoon for eastern Colorado, western Kansas and southwestern Nebraska until late evening.

This weekend's forecasts come in the wake of over 20 previous tornadoes that hit the area last week. In Oklahoma, flash floods caused by torrential downpours killed a woman who drowned in her underground storm shelter. The governor declared a state of emergency for the event.

Winds in the Plains states are expected to reach 70 miles per hour this weekend and flash flooding is once more expected. Damage including ripped roofs, downed power lines and shattered windows may be in store for the already shaken states.
