Houston is starting Sunday with a stormy morning and a scorching afternoon — showers and thunderstorms are possible through about 1 PM CT before skies partially clear, with the high climbing to near 90°F and a heat index that could reach 106°F. If you have outdoor plans, timing is everything today.

Today’s Setup

The National Weather Service says the highest storm risk runs from the Gulf coast inland toward the I-10 corridor. Neighborhoods from Galveston through Clear Lake and the South Belt face the best chance of locally heavy downpours. The NWS notes a slight excessive rainfall risk for coastal spots, and with Houston’s bayou system, even a half to three-quarters of an inch of rain can cause issues in low-lying areas — stay weather-aware this morning. Once rain clears mid-afternoon, a south wind of 5–10 mph gusting to 20 mph will keep the humidity suffocating well into the evening.

Best Window To Be Outside

Your clearest outdoor window opens after 1–2 PM CT as storm chances fade. That said, don’t underestimate the afternoon heat — 90°F with a 106°F heat index is genuinely dangerous. Keep an insulated tumbler 30oz filled with ice water on hand, limit heavy exertion, and take shade breaks often.

Game Day at Daikin Park

The Houston Astros host the Cleveland Guardians today at Daikin Park — and it’s a City Connect Soccer Scarf giveaway day. Time your arrival after 1 PM CT to dodge the morning storms. Once the sun breaks through, shade and sun protection matter — a Houston Astros fitted cap goes a long way, and a Houston Astros jersey keeps you repping the team in style. Still need seats? Get tickets on SeatGeek or Find tickets on StubHub.

More Events This Week

The 2026 World Cup lands at NRG Stadium on Tuesday, June 23 — Portugal takes on Uzbekistan in Group K Match 47. Expect heat indices near or above 100°F for daytime matches, so plan accordingly. Also on June 23, Ilana Glazer Live! plays 713 Music Hall — a smart indoor option when the heat is relentless. Check outdoor gear deals if you’re prepping for any of the week’s outdoor events.

Heat Risk Through Midweek

This is the real story this week. Monday climbs to near 93°F with a heat index up to 107°F, and overnight lows barely dip below 80°F — almost no overnight recovery. The NWS is flagging this heat through at least midweek. The National Weather Service also warns of a high rip current risk continuing along Gulf beaches over the next several days — swim near lifeguards if you head to Galveston, and heed any posted flags. Stay up to date with the Houston weather forecast.

Too Hot to Cook

Skip the oven tonight — try smoothie bowls or a cold Thai noodle salad instead. A high-powered blender handles frozen fruit bases in seconds, and an insulated tumbler 30oz keeps your drinks ice-cold through the evening. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Monday brings mostly sunny skies and a high near 93°F. Tuesday trends even warmer. No meaningful rain relief is in sight through early next week — just relentless Gulf humidity and dangerous heat indices. Stay cool, stay hydrated, and keep a weather eye on those bayous whenever afternoon storms pop up.
