San Antonio is currently under a Severe Thunderstorm Watch as a complex of storms approaches the Gulf Coast. The earlier Tornado Watch that was issued for the area has ended, but the possibility of severe weather remains significant, particularly tonight and into tomorrow.
Storm systems are bringing strong winds characterized by a phenomenon known as a Wake Low, which is expected to create a tight pressure gradient resulting in winds gusting up to 40 mph or more. Although the immediate risk for severe storms has decreased in Bexar County after experiencing heavy rain, gusty winds, and hail, meteorologists are warning residents to remain vigilant as another round of storms is anticipated this evening, particularly in the western regions of the county.
As the evening progresses, forecasts suggest that severe thunderstorms may develop along an outflow boundary starting post-7 p.m. and lasting until around 2 a.m. The primary hazards during this period include large hail potentially reaching the size of tennis balls and damaging winds. While the chances for tornadoes are lower, the National Weather Service has issued a new Tornado Watch in anticipation of severe hail and strong winds throughout the area.
In terms of the broader region, Texas is poised for a multi-round severe weather event, with scattered thunderstorms extending into the Texas Panhandle and North Texas. A Level 1 out of 5 risk for severe weather is applicable for areas including San Antonio, but higher risks have been forecasted for the northern half of the state. Residents are advised to monitor weather updates and prepare for possible severe weather conditions over the next few days.
On Memorial Day, the probability of storms is predicted to rise, reaching approximately 30%. The overall threat for severe weather in San Antonio, however, is deemed to be low. While temperatures are expected to soar to around 97 degrees, the heat indices may exceed 100 degrees, presenting additional risks of heat exposure for residents engaging in outdoor activities.
As for tomorrow’s weather, Central and South Texas are expected to see storm chances increase, with probabilities ranging from 50% to 60% for the afternoon and evening. However, even with these storm chances, warm temperatures are projected to persist, with high temperatures anticipated to remain in the low 90s later in the week.
In light of these conditions, residents are urged to have shelter plans ready and to take immediate action should severe weather warnings be issued. The combination of heat and potential thunderstorms underscores the importance of staying informed and prepared for changing weather patterns.
With severe weather risks evolving, monitoring local forecasts and taking appropriate precautions will be crucial for the safety and wellbeing of San Antonio residents in the coming days.
