FORECAST<\/p>\n
100\u00b0 TODAY<\/p>\n
Rainfall has kept us relatively mild so far this summer. San Antonio\u2019s average first triple digit day usually comes at the end of June. And while we\u2019re about a month late, we\u2019ll likely see 100 degrees this afternoon. High humidity will make it feel more like 105\u00b0 to 110\u00b0.<\/p>\n
Today’s forecast for San Antonio (Copyright 2026 by KSAT – All rights reserved.)<\/p>\n
It won\u2019t just be toasty in and around San Antonio. Heat Advisories and Extreme Heat Warnings are in place across most of Texas. Yes, we\u2019re used to heat in the summer, but because our bodies have yet to acclimate to the triple-digits, please use caution if working or enjoying time outside today, especially from 1 pm to 7 pm.<\/p>\n
Other than the heat, there is a small (20%) possibility for a stray shower overnight, with the approach of a very weak Tropical Storm Bertha. Speaking of…<\/p>\n
T.S. BERTHA<\/p>\n
Weak Tropical Storm Bertha’s path (Copyright 2026 by KSAT – All rights reserved.)<\/p>\n
Bertha has weakened a bit as it approaches the Louisiana coast. Today, Bertha will bring some rain and gusty winds to areas near New Orleans. A mild storm for an area that has had its fair share of very strong hurricanes. <\/p>\n
As Bertha moves west toward the Texas coast, it will weaken even further, having a barely noticeable impact near Beaumont\/Houston\/Galveston Thursday. It will completely dissipate by Friday morning.<\/p>\n
Bottom line with Bertha: No major impacts, and it should not affect travel plans. It will be completely gone by the weekend.<\/p>\n

NUECES & FRIO RIVERS<\/p>\n
It is taking a long time for the nearly 500 billion gallons of water that fell last week to drain into Choke Canyon and Lake Corpus Christi along the Nueces and Frio Rivers. Areas of Cotulla and Tilden along the rivers are still flooded. Cotulla, specifically, can expect the Nueces to remain at major flood stage through the weekend.<\/p>\n
LOCAL LAKES & AQUIFERS<\/p>\n
We\u2019re seeing the highest levels in Canyon Lake, Medina Lake, and the Edwards Aquifer in four years.<\/p>\n
As mentioned above, Choke Canyon and Lake Corpus Christi will eventually rise from flood waters. We\u2019ll keep you posted.<\/p>\n
