From Rusty Garrett:
Thanks to an overnight cool front, afternoon temperatures Tuesday were noticeably more seasonal than Monday, but readings will continue to fluctuate up and down this week.
With winds going calm Tuesday evening and skies remaining clear, temperatures should drop into the lower and middle 30s area wide overnight.
Following a brief chill at dawn, winds from the south and southwest will begin to increase, allowing warm and dry air to move back across the area. Highs Wednesday should reach the upper 60s and lower 70s.
Another front moves through Central Texas Wednesday night, and since cooler air will lag behind the front, morning lows Thursday should remain near average in the middle and upper 30s. You'll notice the temperature change Thursday afternoon, as highs again only reach the upper 50s and lower 60s. Cooler air will stay in place through the day Friday too, keeping highs in the upper 50s and lower 60s.
Another cool front is set to move through Central Texas Sunday. If enough moisture moves back into our area, Sunday's front may be able to spark a few showers, especially east of I-35. As of now, Sunday's rain odds stand at only 20%, with best coverage east of I-35. Late weekend highs are expected in the middle 60s.
