As an Arctic blast barrels into Southeast Texas this weekend, Houston-area businesses and event organizers are announcing closures and cancellations due to the threat of freezing temperatures and potentially dangerous conditions.

Thousands of homes and businesses were without electricity Sunday morning in the Houston region, where residents awoke to cold, wet and in some cases icy conditions as a winter storm moved in.

As winter weather confidence grows, some Houston-area school districts are canceling or postponing weekend events to reduce travel risks.

National Weather Service predicts freezing temps might be even colder than expected for this weekend's winter storm, placing Houston under extreme cold watch.

Climate scientists and policy experts say extreme weather is inevitable-but how Houston prepares for it can make all the difference.

Houston residents face severe weather including thunderstorms and an arctic blast, potentially leading to freezing rain and power outages.

CenterPoint Energy hosted a final daily update on operations for Houston's winter weather. CBS had a good idea on Sunday for its broadcast of snowy conditions in the AFC championship. But the network quickly and wisely abandoned it as the execution caused more problems then it solved.
