From Rusty Garrett:
Central Texas weather will be a bit chaotic over the next 7 days as a parade of fronts keep minor cold air masses around. The first chilly air mass arrives late night. A few scattered showers will be possible mainly near and east of I-35.
Strong northwest winds will mark the front's passage and temperatures will drop down into the 30s by morning. Most of Central Texas will see the scattered rain stay liquid despite the falling temperatures, but in Falls, eastern Bell, Limestone, and Freestone counties, any scattered rain that falls after 2 AM may have isolated sleet pellets thrown into the mix.
If wintry precipitation reaches the ground east of I-35, temperatures will NOT be cold enough to support any accumulations of snow or ice on surfaces.
Wednesday's winds may gust to near 30 mph at times, keeping wind chills in the 20s and 30s through midday. It won't be until late afternoon that the winds begin to subside, and as far as actual temperatures go, highs Wednesday should be able to reach the mid/upper 40s. Thereafter, readings should drop below freezing Wednesday night into the upper 20s and low 30s, but southerly winds will warm us back into the upper 50s Thursday afternoon.
