From Rusty Garrett:
Following a chilly Wednesday morning, with lows in the 20s and 30s, we were back to the upper 60s and lower 70s by the afternoon. However, Thursday will bring a return of more seasonable weather as a cool front moves through.
The front is set to move through Central Texas slowly late night. While the boundary will clear the area by sunrise, the cooler air will lag behind a bit. Morning lows Thursday will be in the upper 30s, nearly 10° warmer than Wednesday morning. Cooler air will gradually move in through the day on brisk northerly winds gusting to near 25 mph at times. Highs should remain in the upper 50s and lower 60s.
Another surge of cooler air arrives Friday sending lows at dawn near or below freezing while afternoon highs remain in the middle and upper 50s.
Eventually, a bit more moisture moves back in, ahead of an upper-level disturbance Saturday. This disturbance should bring some rain into our area by the late afternoon and evening. The best chance of rain should remain near and east of I-35 after 3 PM, ending shortly after midnight. Highs should remain in the middle and upper 50s Saturday under mostly cloudy to overcast skies.
