Severe weather chances prior to Sunday’s big cool-down
DENVER -- Scattered thunderstorms late Friday and again Saturday will bring a chance of severe storms to the area, particularly the Plains, ahead of a 20-degree drop for Sunday's temperatures. For Friday evening, a few storms will be around the metro areas but much stronger to potentially damaging storms will be over the Plains. The environment there supports large hail, damaging wind and tornado formation. The metro areas will likely have quite the lightning show off to the east from these storms.
