The KHOU 11 team is tracking the potential for wintry, icy weather yet again north and west of Houston early Wednesday morning as another round of precipitation sweeps through the state. We're also tracking millions still without power statewide and very low water pressure — including some who have no water at all.

Will it freeze in Houston again today? Will there be ice here? Meteorologist Chita Craft says the freezing rain line is essentially Tomball to Livingston. Points north will get it — points south may luck out and will likely get only a cold rain today. She says spots north of that Tomball line — Brenham, College Station, Huntsville, etc — could get half an inch to an inch of ice today. Watch the latest forecast and view live radar here. 

A second Winter Storm Warning was issued for the northern and central areas of southeast Texas starting midnight Tuesday through 6 a.m. Thursday. Our team of experienced KHOU 11 meteorologists is tracking the winter storm around the clock.
