The late season snow storm has finally begun to produce heavy snow over portions of the Denver Metro area and heading up toward Cheyenne, WY. Blizzard warnings are out for the front range through tonight. The southerly component of this storm brought several tornadoes to the Texas panhandle yesterday. The storm will bring more severe weather to the plains this week. Oklahoma City will get into the severe weather on Tuesday and then all eyes turn to Dixie Alley on Wednesday for what could be a big day for tornadoes.
