• WATER DATA: Rivers, lakes, and the aquifer all rise

FORECAST

SATURDAY

It’ll be warm and humid. There’s a small 20%chance for a stray shower or afternoon storm. Otherwise, highs will reach the low-90s. Humidity will push the heat index to 105° in the afternoon

FATHER’S DAY

Sunday will be similar to Saturday, but I do think there is a slightly higher chance (30%) for rain. It won’t be widespread, but if you do run into a storm in the afternoon, it could produce quarter sized hail. Just have the radar handy for outdoor activities. Flooding is NOT likely.

Next week we’re focusing on the potential for tropical moisture by Thursday and Friday, but as of now, it’s just a 30% chance.

RIVERS, LAKES, AND AQUIFER

The Guadalupe and Comal Rivers are flowing, which will make for good tubing conditions this weekend. Just a small dip in water quality.

A quick check of Medina and Canyon this morning show only small rises of about a foot. It’ll take quite a bit more rain to see any huge movement in these lakes, but this is a start.

Meantime, as Saturday morning, the aquifer is up 8 feet from Tuesday. It’s still rising and is at its highest point since May of 2024. We’ll continue to update these numbers.
