Many areas of the U.S. have been enjoying unseasonably warm weather. But some of those same areas were bracing Monday for the possibility of severe storms.

More than a dozen tornadoes moved across the plains over the weekend.

The National Weather Service warned a powerful cold front in the West slowly creeping east could trigger severe storms from Nebraska to Texas and bring heavy rains and possible flooding in the coming days as it lingers over Texas, Louisiana, and Arkansas.

Forecasters have predicted the possibility of severe weather for parts of Oklahoma and Texas late Monday, with the potential for damaging winds and large hail.

The high winds have created dangerous driving conditions in some places, blowing dust across highways, bringing down trees, and knocking out electric power to thousands.

That same storm system has buried the mountains of Arizona and New Mexico in heavy snow.

Forecasters said the cold front may also bring cooler temperatures to the Midwest in the second half of the week, along with rain, but forecasters said temperatures were likely to remain above normal.

"Things are eventually going to cool down. The question is exactly when," Frank Strait, a meteorologist with AccuWeather.com told Reuters.
