Whatís their normal range?
In January 2009, a snowy owl appeared in Spring Hill, Tennessee, the first reported sighting in the state since 1987. Also notable is the mass southern migration in the winter of 2011/2012, when thousands of snowy owls were spotted in various locations across the United States. This was then followed by an even larger mass southern migration in 2013/2014 with the first snowy owls seen in Florida for decades.
Only problem with this is not many survive such a long trip, plus they have to compete with the huge number of wintering raptors. Rare but sad! From what I can find this is only the tenth one ever spotted in Texas.
