Houston is welcoming Memorial Day with mostly sunny skies and a high near 87°F — great for morning cookouts and parades, but plan to wrap up outdoor activities before 1 PM CT when a slight chance of showers and thunderstorms moves in. Check the full Houston weather forecast for updates throughout the day.

Today’s Setup

Light northeast winds at 0–5 mph and Gulf humidity will push feels-like temps into the lower 90s by midday. The National Weather Service notes better storm chances across the northern half of the region — The Woodlands, Humble, and Conroe — while areas closer to Galveston Island stay drier through mid-afternoon. Overall precip odds are just 20%, with less than a tenth of an inch expected if anything fires. Grab an insulated water jug 1 gallon before heading to Memorial Park or the hike-and-bike trails along Buffalo Bayou — you will need the hydration out there.

Best Window To Be Outside

Your golden window is 7 AM–1 PM CT. Morning parades, backyard grilling, or an early round of golf all look fine. If you have been eyeing new outdoor gear deals for summer, today is a good day to use them. (The Callaway Big Bertha Fairway Wood is $150 right now if you want to upgrade your game before the heat really sets in.) Tuck a packable rain jacket in your bag just in case — Houston afternoon pop-ups near the bayous can build faster than the radar suggests.

Heads Up: Heavy Rain Threat Wednesday

Today’s shower risk is minor. The real story is Tuesday night into Wednesday, when a second storm system pushes in from the west and loads the atmosphere with precipitable water up to 1.8–2.1 inches — deep Gulf moisture that Houston weather veterans recognize. National Weather Service forecasters in the Houston/Galveston office are watching for the potential of training and regenerating storm cells. Widespread rainfall of 1–2 inches is expected, and some models show localized 3–5 inches near coastal counties. If you live near Brays Bayou, Meyerland, or low-lying stretches of Highway 290, Wednesday is a day to watch closely.

A NOAA weather radio is worth having charged before Tuesday night — it is the fastest way to receive flash flood warnings when cell service gets swamped during heavy rain events.

Events This Week

Tonight, Boni’s Dance – Boni’s Journey Through Time takes the stage at the Cynthia Woods Mitchell Pavilion — timing looks clear ahead of any evening showers. Later this week, The Kid LAROI brings the A Perfect World Tour to Bayou Music Center on Thursday, May 28 — grab tickets on SeatGeek before they’re gone. Then GODSMACK headlines the Cynthia Woods Mitchell Pavilion on Saturday, May 30 for The Rise of Rock World Tour 2026. The second half of the week looks drier as a mid-level ridge builds back in, so Saturday night should be a solid outdoor show. A Godsmack t-shirt is great concert gear, and a Godsmack hoodie is smart for a chilly amphitheater AC situation.

Rainy Day Dinner Idea

With a wet mid-week on the way, set a programmable slow cooker loaded with chili or beef stew before you head out this morning — dinner will be ready when storms roll in. An enameled cast iron Dutch oven works just as well for a big pot of soup on a gray afternoon. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

  • Tuesday: Partly sunny, high near 87°F, 30% storm chance
  • Tuesday Night–Wednesday: Storm system arrives — 1–2” of rain broadly, localized flooding risk near bayous and coastal counties; NWS is watching for training cells
  • Thursday onward: Conditions improve as the system clears; drier and less active weather returns through the weekend
