Hot and humid weather takes over for much of next week as Houston gets ready for World Cup events. Highs should return to the low 90s with steamy afternoons, warm mornings, and only isolated storm chances.

Saturday night's Pride Houston parade was cancelled because of rainy weather, organizers said in a Facebook post. The annual parade was scheduled to start at Houston City Hall at 7:30 p.m. and proceed through downtown Houston before concluding at 10 p.m.

Houston is under a Flood Watch through Saturday morning, and storms could bring heavy rain alongside risks of large hail, damaging winds and even an isolated tornado. The National Weather Service Houston-Galveston Office issued a Flood Watch beginning at 3 a.

Heavy rain expected Friday could once again flood some of Houston’s most vulnerable streets and underpasses, including one particular trouble spot.

A shortwave of low air pressure has combined with a surge of moisture-rich air from the Gulf of Mexico to trigger widespread heavy rainfall.

Between June 5 and 9, 2001, Tropical Storm Allison meandered over Texas and Louisiana, bringing 30 inches of rain to both states. In Houston, over 73,000 homes and 95,000 vehicles were flooded.

Friday's downpours brought rising water to Cedar Creek Bar & Grill in the Heights as heavy rain triggered flooding concerns across Houston.

Scattered thunderstorms remain in Houston's forecast through the weekend, but increasing Gulf moisture could bring heavier downpours and a growing flood risk.
