San Antonio Weather Update: Mild Conditions This Week with Possible Storms Ahead

Greetings, San Antonio! As we gear up for another week, let’s dive into what the weather has in store for us in the coming days. You can expect mild and mostly comfortable conditions, but don’t put those umbrellas too far away just yet—there are some storm clouds on the horizon!

Monday: A Rain-Free River Parade!

Starting off the week, Monday, April 28, 2025 is looking pretty good! While a few storms may pop up on the border, San Antonio is predicted to stay dry and bright for the River Parade. A bit of humidity will hang in the air, which might give you that sweaty summer feel, but overall it should be a lovely day. Expect morning temperatures in the upper 60s, gradually climbing to around 80°F by noon, and the highs could soar into the upper 80s, hitting close to 90°F in the afternoon!

Beware of the Heat Index!

Alongside the warmth, high humidity levels could create a steamy heat index that feels like it’s between 91°F and 93°F. So, while the sunshine invites you to enjoy the outdoors, make sure you stay hydrated and keep cool!

Midweek Storm Watch

Now, let’s fast forward to midweek—Wednesday is forecasted to be where we see the action ramp up a bit. Showers and thunderstorms are likely, with a 50% chance of storm activity. So if you’re planning to take part in local events, keep your eyes peeled for weather updates!

Parade Alerts

Rain chances for the Battle of Flowers and Flambeau parades will also be monitored closely, as only isolated showers or storms are currently on the radar. But as always, it’s better to be prepared just in case the weather takes a turn! So, maybe stash a light poncho in your pocket just in case.

Weather Systems at Play

The weather will see a change as a low-pressure system moves closer to Texas, contributing to the instability and moisture required for severe thunderstorms. Unlike Sunday, when severe storm chances were low—mostly staying west of us (think Amarillo, Lubbock, and Midland)—this new system means we should keep a close watch on conditions moving into the week.

Temperatures Steady

Throughout the week, San Antonio’s temperatures are expected to remain stable. Mornings will greet us with lows in the low 70s, and highs will consistently hover in the mid to upper 80s. No wild temperature swings here! Just nice, warm, spring air.

Keep an Eye on Tuesday

As we inch into Tuesday, rain chances are relatively low—hovering around 20-30% by nightfall. So if you’re heading out for dinner or a stroll, the weather should cooperate! But, remember, excitement is in the air for midweek when storm chances really heat up.

Wrap Up

So, there you have it, San Antonio! A week filled with mostly mild conditions but some stormy potential midweek. Make the most out of those beautiful mornings, and remember to stay informed as the forecast changes. Until next time, enjoy the sunny spots and be ready for whatever the skies might throw our way!
