DENVER (AP) - A powerful spring storm is dropping more than a foot of sloppy, wet snow in parts of Colorado and Wyoming on Mother's Day.
Forecasters are warning that conditions could get worse as temperatures plummet overnight.
The National Weather Service has issued a winter storm warning for most of northern Colorado and parts of southern Wyoming through Monday morning.
Forecasters are also warning that strong thunderstorms and possibly tornadoes could develop in eastern Nebraska and Iowa until late this evening.
In Colorado, snow amounts could vary greatly, but up to 15 inches could fall at higher elevations and 4 to 9 inches could fall at lower elevations, including Denver and other cities along Colorado's Front Range.
The weather service is also warning that snow could be heavy and wet enough to snap tree limbs and power lines, causing power failures. Winds gusting up to 30 mph could reduce visibility, and slushy roads could be treacherous to drive.
