KSAT’s Weather Authority has a hot, humid weekend ahead for much of the viewing area with highs near 90, a touch of morning mist Sunday, and a more unsettled pattern arriving next week that brings daily storm chances of roughly 30% to 40% and the potential for strong storms into Memorial Day weekend.

The weekend opens mostly cloudy with humidity making it feel heavy in the morning, but afternoon sun will push temperatures toward the upper 80s and around 90 degrees. Stay mindful of heat exposure if you plan to be outside for long periods, since our bodies haven’t fully adjusted to this quick jump in warmth. Simple precautions like water, shade, and limiting strenuous activity during peak sun will keep everyone safer and more comfortable.

Saturday’s setup rewards patience: morning clouds give way to widespread afternoon sunshine and a noticeable rise in temperature. Expect peak heat in the afternoon hours as skies clear and humidity lingers. This is a classic early-summer pattern where we get warm, bright afternoons after a muggy start.

Sunday begins with patchy morning mist that will hang around low-lying spots before burning off into the afternoon. Clouds will be a little more stubborn than Saturday but there will still be sun in the afternoon and temperatures will stay close to 90 degrees. It’s a repeat of the brief summer-preview feel, with warm days and sticky nights.

Looking toward next week, the pattern shifts. A series of disturbances and a slow-moving cool front will make the weather more unsettled, and that translates into daily storm chances rather than a single wet day. Coverage won’t be widespread every day, but scattered storms will be possible.

Storm chances are modest in percentage but worth watching: 30% to 40% coverage means not everyone sees rain, but where storms do develop they can be intense. Timing and exact placement are impossible to pin down this far out, which is why pockets of strong or severe weather remain a credible threat. Storms that tap into heat and humidity can produce gusty winds, frequent lightning, and heavy downpours in a short period.

On days with storm development, impacts will be localized, so neighborhoods a few miles apart could see very different outcomes. That variability is typical with scattered convective setups early in the season. Residents should keep a battery-powered radio or a weather app handy for on-the-go updates when storms are expected.

Even on quieter days, low-end rain chances will hang around, and isolated showers could sneak in during the late afternoon or evening. These little disturbances won’t overhaul the pattern, but they will influence outdoor plans and could create sudden downpours. If you have outdoor events planned, especially late in the day, have a quick backup or a shelter option ready.

Memorial Day weekend could still see lingering storm chances as the front takes its time washing through the region. It’s too early to forecast any single holiday-maker’s impact, but the tendency toward scattered storms will likely remain in place. That means staying flexible with plans and keeping up with the short-term forecasts.

For real-time updates and radar views, KSAT recommends checking the live Doppler and hourly forecast products available through its usual channels. Local meteorologists will tighten timing and placement details as each day approaches, which is why the forecast can change from morning to afternoon. Prioritize the most recent guidance if you’re scheduling outdoor activities.

If storms do fire up next week, the main hazards to watch will be strong gusty winds, frequent lightning, and heavy rain that could cause brief urban or poor-drainage flooding. Tornadoes are not the primary signal at this time, but any severe setup can include a range of threats depending on how the atmosphere organizes. Treat lightning as a real hazard and seek shelter indoors at the first rumble or flash.

Heat-related concerns should not be ignored even with storm chances in the forecast. Humid afternoons near 90 degrees can be taxing, especially for kids, older adults, and pets. Hydration, shade breaks, and limiting prolonged exertion are simple steps that reduce heat stress risks during this transitional period.

Keep an eye on the KSAT Weather Authority app and local forecasts as the week progresses for updated storm probabilities and timing. Meteorologists will refine the details and issue any watches or warnings if conditions escalate. In the meantime, plan for a warm weekend and a week of rolling, spotty storms that could be strong where they occur.
