Houston rolled into Sunday morning already feeling like a steam room, with temperatures hovering near 70°F, clear skies, and humidity thick enough to notice. Dewpoints in the mid-60s are helping to spin up patches of fog and mist in low-lying spots, so some neighborhoods could see reduced visibility during the commute until the sea breeze kicks in. Light east to northeast winds early today should keep most of the heavier action offshore, although a few brief downpours cannot be ruled out this afternoon.
Memorial Day And Midweek
Memorial Day itself looks warmer, with highs pushing into the mid-80s and a modest chance of afternoon showers or thunderstorms popping up across parts of the metro. According to NWS Houston/Galveston, the Flood Watch that had covered much of the region has now been trimmed back to coastal counties. Forecasters are already eyeing a stronger system that may arrive Tuesday night into Wednesday, with the potential for more widespread heavy rain. With soils still wet in many neighborhoods, even slow-moving storms could quickly trigger urban street flooding where storms repeatedly track over the same areas.
Afternoon Spotty Storms
For today, the overall rain risk stays on the low side, with only about a 20 percent chance of scattered showers and thunderstorms. Most of the metro should top out near 82°F, with northeast winds around 5 to 10 mph. Any storms that do manage to fire up are likely to be brief but capable of dumping heavy rain and causing localized ponding on streets. Coastal neighborhoods could see higher rainfall totals if onshore flow hangs on a bit longer. If you have outdoor plans, a light rain jacket is a smart accessory.
Marine And Flood Outlook
Anyone headed to the bays or the beach will want to stay weather-aware. Moderate east to southeast winds and scattered coastal storms are expected to make bay waters choppy and may help push heavier showers and thunderstorms onshore at times.

If you are hosting a Memorial Day gathering, it is worth having a backup plan and a reliable way to receive local weather alerts.
What To Bring
Plan on packing a light rain jacket, waterproof shoes for low-lying streets, and give yourself a little extra time on the morning drive in case fog lingers. We will continue to monitor any changes to watches or warnings and will update readers if the Flood Watch or coastal advisories are adjusted.
