DALLAS -- Dallas was hit with an ice storm overnight that put an inch or two of slick coating on top of the roads. It forced the closing of North Texas schools and all commuter rail service was shut down. It might not have caused the closing of schools in Western New York, given the region's greater ability to put salt down on roads. Dallas-Fort Worth airport was closed for a couple hours this morning. Media buses got a police escort down mostly empty Interstate 30 en route to Cowboys Stadium. Forecasts call for high temperatures of 14 degrees Wednesday, 28 Thursday and the low 50s by the weekend.
