PREPARE FOR COLD:
Now is the time to prepare your home for extended cold: insulate exposed pipes, cover outdoor faucets, make sure your pets will be inside with you this weekend.
Expect be be below freezing for at least 24 hours and perhaps even longer, depending on temperatures Sunday afternoon. Sunday, Monday, and Tuesday mornings will be well below freezing.
IMPACTS:
The most severe effects will depend on how much ice actually forms. Currently, we do expect at least some icing around San Antonio.
Even a small amount of ice—a “glaze”—might cause slick roads and sidewalks, while a tenth of an inch of ice can cause overpasses and bridges to become impassable.
At this point, travel from San Antonio and points north would be discouraged. Higher amounts of ice are expected in the Hill Country and points north.
COLD MORNINGS
With some clearing by Monday morning, bitter cold morning temps are expected for a few days.
