The Electric Reliability Council of Texas, the state's power grid operator, is expected to pass its second test of the winter early next week, when another arctic front is anticipated to bring frigid temperatures to much of the state.

The Houston area is seeing an increasing chance that a mix of wintry precipitation—including snow—is headed in its direction. Space City Weather meteorologist Eric Berger said there is a growing possibility (about a 50-50 chance) of snow or sleet beginning next Monday night and Tuesday.
