It won't be long before the rain moves in again. An overnight shift of an upper low into Mexico favors the heaviest rainfall west of I-45. That's where the KHOU Doppler radar is painting the heaviest rain now. If you're heading out west to San Antonio on I-10, watch out for hydroplaning.
Here's an enhanced water vapor satellite image. The heaviest tropical moisture is shaded in red and continues to favor south Texas and the Gulf Coast with .50"- 2" rainfall amounts in a few spots today.
The satellite is dialed in to the wavelength of moisture. In this case, the deeper shades of green reveal moist laden air over the south-central areas of the state of Texas. The swirl over Mexico is an upper low funneling the moisture our way. The low slowly fills by Monday diminishing our rain chances from 50% today to 20% Monday.
If you're planning any outdoor activity today, get around the storms by getting our KHOU weather app for your mobile device for the latest updates. You can also go to KHOU.com for Doppler views in your neighborhood.
