Light snow fell on this panhandle city Wednesday as the last remnant of an unprecedented, deadly storm rolled out to sea after smashing snow records from here to New Orleans and casting a blanket of ice across a region not targeted by such a severe wintry assault in generations.

The snow storm could hit over a dozen states through Wednesday, including Texas, Louisiana, Mississippi, Alabama, Florida, Georgia and the Carolinas.

All airports in Houston shut down on Jan. 21 as a winter storm barreled through South Texas.
