Houston is getting one more clear, dry day before the weekend turns soggy. Friday starts in the mid-50s under sunny skies, with temperatures climbing to around 72 degrees before easing back later in the afternoon.
The sharper change arrives Sunday, when showers and thunderstorms are expected across the region with a 60% chance of rain. The National Weather Service Houston/Galveston says locally heavy rainfall is possible, while the latest forecast is a more serious turn than the weekend outlook described by Hoodline Thursday.
Saturday Starts Quiet, Then Winds Pick Up
Saturday will be partly sunny and cooler, with a high near 65 degrees. East winds will run 10 to 15 mph and could gust to 25 mph. Rain chances return Saturday afternoon and continue overnight as clouds thicken.
The overnight rain chance is about 30%, with Gulf moisture moving in. Outdoor plans can probably survive the daytime, but Saturday evening looks like the point where Houston’s dry spell starts losing its grip.
Sunday Brings Heavy Rain And Thunderstorms
Sunday is expected to be the wettest day of the forecast, with rain showers likely before thunderstorms become possible after 3 p.m. Temperatures will hold near 65 degrees, with east winds around 15 mph and a 60% chance of rain.
Forecasters say locally heavy downpours could produce minor street flooding, especially where rain falls hard for an extended period. Showers and thunderstorms are expected to continue Sunday night, with another 70% rain chance and a low near 57 degrees.
Monday Turns Cooler Before A Midweek Rebound
A cold front is expected to move through late Sunday night into early Monday, bringing cooler, drier air behind it. Monday will be colder and dry, with about a 50% chance Houston’s high remains below 60 degrees, followed by a mostly sunny Tuesday near 62.
Temperatures should gradually rebound during the second half of the week, reaching about 67 degrees Wednesday and 70 Thursday. Thursday also carries a 30% chance of showers, so the warm-up may come with another reminder that fall in Houston rarely sticks to one script.
Gulf Waters Turn Rougher
Boaters should expect deteriorating conditions late Saturday through early next week, with seas building to 7 to 10 feet Saturday and Sunday. Near-gale conditions are possible Sunday ahead of the front, and small-craft advisories may be issued as winds and seas increase.
