A cold front will push through League City on Friday, Oct. 16, dropping weekend highs from the mid-80s into the mid-70s. The National Weather Service is also warning of hazardous conditions on Galveston Bay and the Gulf of Mexico as strong winds build behind the front.

The NWS Houston/Galveston office posted two active headlines Wednesday, Oct. 14: "Late Week Front" and "Hazardous Marine Conditions." In a Tuesday, Oct. 13, post on X, the agency called the system the season's first "real" fall front.

What League City residents will feel

Friday's high should still reach 84°F with a chance of showers as the front moves through, according to the NWS point forecast for League City. The change hits Friday night: the low drops to 60°F under partly cloudy, breezy skies.

Saturday, Oct. 17, brings a high of just 74°F with mostly sunny and breezy conditions. Saturday night dips to 58°F. Sunday climbs to 77°F under clear skies.

Houston Chronicle meteorologist Justin Ballard reported the cooler stretch will be brief. High pressure is expected to shift east early next week, pushing temperatures back into the 80s.

NWS warns of hazardous bay conditions

The marine forecast carries the sharper warning. The NWS Coastal Waters Forecast, issued at 6:49 a.m. Wednesday, said Small Craft Advisories will likely be required and that some gale-force conditions are increasingly possible late Friday night into Saturday.

On Galveston Bay, north winds are forecast to build from 15 knots Friday afternoon to 25–30 knots Friday night, pushing bay waters to rough conditions and very rough after midnight. By Saturday morning, winds could reach 30 knots before easing in the afternoon.

In the nearshore zone out to 20 nautical miles between High Island and Freeport, Friday night calls for north winds around 30 knots with gusts to 40 knots and seas of 5 to 7 feet, occasionally reaching 9 feet.

Farther out in the offshore zone, 20 to 60 nautical miles from shore, Saturday seas could build to 7 to 10 feet with occasional swells to 13 feet.

The NWS noted that more than 100,000 registered vessels use upper Texas coast waterways. No gale warning has been issued, but the agency said probabilities for some gale conditions continue to trend upward for late Friday night and Saturday. Conditions are expected to gradually improve Saturday night into Sunday.
