(KTEN) — Texoma woke up to another sub-freezing morning on Thursday — Groundhog Day — but the end of the winter weather event that shut down schools and businesses across the KTEN viewing area is almost here.

While skies will be mostly cloudy, temperatures will inch above freezing, helping to melt the ice that has been accumulating since Monday. But watch for another night of freezing temps that could delay plans to head to work or classrooms on Friday morning.

More than 390,000 customers in Texas were without power early Thursday as trees, heavy with ice, buckled onto power lines, according to PowerOutage, a website tracking utility reports.

More than 150,000 of those outages were in Austin, where the city’s utility warned residents who had been without electricity that lights and heat may not come back on until later Thursday.

Most schools across the KTEN viewing area plan to remain closed on Thursday, some with remote learning programs in place.

Nearly 700 flights scheduled for Thursday already had been canceled by Thursday morning, according to the flight tracking service FlightAware.com. That followed thousands of cancelations and delays since frigid weather set in Monday.
