Rethinking the way we landscape in Central Texas
Wednesday morning's rain did little to quell Central Texas' dry spell.

Rare "wake low" to blame for widespread wind damage Tuesday night
CBS Austin Meteorologists warned you of the potential for severe storms and damaging wind gusts in the late Tuesday evening hours. That threat came to fruition, but not in the way that was expected.

Lightning, thunder, some gusty winds, sure... but it was what developed behind the rain & storms that did the most damage.

Wet, chilly weekend ahead for Central Texas
If you looked out the window on Thursday between 9 AM and noon, you probably saw a decent amount of sunshine beaming through the clouds... If you missed it, you’ll have to wait until the middle of next week to see any sunshine again.
