Sunday


Morning

A line of thunderstorms could move through around sunrise, with strong storms possible in parts of the region.The main batch of storms may push through by around 9 a.m.


Afternoon

The front is expected to stall instead of moving offshore, keeping conditions unsettled.Scattered showers and storms possible off and on throughout the day.Rain chances around 60%.


Rainfall outlook

Most of the Houston area could see 1 to 2 inches of rain through early Monday.Some isolated locations could receive 3 to 4 inches, which could cause street ponding or localized flooding, though widespread flooding of creeks and bayous is not expected.


Looking ahead

Another spring storm system could bring rain chances Tuesday and especially Wednesday, with the potential for additional strong storms.After that system passes, cooler temperatures are expected late next week.

Forecasters say the exact timing of the weekend storms could still change, and updates are likely as new data comes in.


What this means for weekend plans

The timing of the storms could impact Saturday afternoon and evening activities, including trips to the Houston Livestock Show and Rodeo, travel around the city, or visits to Galveston.

Heavy rain could reduce visibility and create slick road conditions during peak travel hours.


Looking ahead

Before the weekend storms arrive, Southeast Texas will see breezy conditions with clouds and occasional sunshine.

Earlier fog reduced visibility in some areas, but conditions have improved.

The KHOU 11 Weather Team will continue monitoring the system as it approaches, especially for any changes in storm timing or rainfall totals heading into Saturday.
