OK, the cold air is in place in northwest Canada with temps there well below zero in spots. Computer models continue to suggest a cold air outbreak here in Houston arriving around Thanksgiving day, or maybe the day after Thanksgiving. Any way you slice it, if the computers are right, we'll see temps dropping into the 40's and 30's and STAYING THERE through the big weekend. This is a long range forecast that is subject to greater uncertainty so stay tuned for updates. We'll be watching it each morning on 11 News This Morning until it gets here.
