Texas Weather: Statewide Temperatures to Vary Widely, from 30s to 90s

An upper-level low pressure system is on track to influence Texas weather this weekend. A cold front will sweep through the state, affecting temperatures significantly by Saturday. However, this front is centered several hundred miles north, resulting in uneven coverage across the state.

Temperature Variance Across Texas

This weekend’s forecast indicates a wide temperature range across Texas, from the chilly 30s to the unseasonably warm 90s. The front will segment Texas, providing relief from heat in the northern regions, while leaving southern areas, particularly San Antonio, exposed to record-breaking temperatures.

Friday Forecast

• Morning lows will be in the mid- to upper 60s.
• Temperatures will rise to the mid-80s by noon.
• Highs will approach 90 degrees by late afternoon.

Humidity levels are expected to increase as moisture moves in from the Gulf of Mexico. This will lead to warmer evening temperatures, with San Antonio projected to remain in the mid-80s until late at night.

Saturday’s Highs and Records

Saturday’s weather looks particularly intense, especially for San Antonio. Morning temperatures may start near 70 degrees, quickly rising to around 90 degrees by early afternoon. Predicted afternoon temperatures range from 92 to 94 degrees, potentially breaking the previous record of 93 degrees set in 2007.

High humidity levels will push the heat index to an uncomfortable 95 or 96 degrees, a notable occurrence for mid-October.

Impact of the Cold Front

The northern third of Texas will feel the most significant impact from the cold front. In the Dallas-Fort Worth area, temperatures are expected to drop by 10-12 degrees, with highs falling from the low 90s to around 80 degrees by Sunday. Morning lows in North Texas could dip into the 50s.

• The Texas Panhandle will experience the lowest temperatures, with morning lows falling to the low to mid-40s in cities such as Amarillo, Childress, and Lubbock.
• Some northern towns might see evening temperatures drop to the mid- to upper 30s.

Thunderstorms may develop along the front on Saturday and could produce large hail and damaging winds, especially in North-Central and Northeast Texas. However, the chance of rain diminishes in San Antonio, with only a 20% chance of precipitation into Sunday.

Weather Outlook for San Antonio

The cold front may pass through San Antonio late Saturday into early Sunday, but it will weaken significantly. Sunday temperatures will likely remain in the upper 80s, close to Saturday’s high.

Look for the heat to persist into early next week, with highs forecast to linger in the lower 90s and morning lows in the upper 60s. Models hint at the potential for a second cold front around October 22-24, indicating a more active weather pattern may be on the horizon.
