The temperature reached 100 degrees in Lufkin Sunday afternoon. Thatâ€™s the first official 100 degree temperature recorded in East Texas this year, and we could see more today. Tonight, the weather will begin to change with the approach of a cold front from the north. There will be a 40 percent chance of thunderstorms ahead of the front. High temperatures will be near 90 degrees, and winds will be north from 5 to 10 mph by Tuesday afternoon. We will just be getting started with the rain for the week.
