ABC13 Weather Watch: Rainmaker could bring street flooding Thursday night and Friday

HOUSTON, Texas (KTRK) -- Wednesday will be our last dry day ahead of a rainy weather system that could bring street flooding later this week. We've put out an ABC13 Weather Watch for when the heavy rain blows in Thursday night and Friday, especially in our coastal counties south of I-10. The National Weather Service office in Houston/Galveston has issued a Flood Watch for Brazoria, Jackson, Matagorda, and Wharton counties starting at 7 a.m. Thursday until 1 p.m. Friday. The National Weather Service office in Corpus Christi has issued a Flood Watch for Calhoun County that starts at 1 p.m. today and runs until 12 p.m. Friday.

Today we will have more clouds than sun with temperatures warming into the mid 80s.

When does the rain arrive?

Showers are possible west of Houston starting this evening and overnight. Otherwise, rain showers will return during the day Thursday and spread through Southeast Texas from west to east. We've increased rain chances to 60% for Thursday with the heavier and more widespread rains arriving Thursday night and Friday morning as the main storm system moves overhead.

How much rain are we expecting?

We believe 1 to 3" will be common across Southeast Texas with most north of I-10 closer to the 1" side of the range and those south of I-10 likely to pick up higher amounts. We are seeing a strong signal that training thunderstorms could set up closer to Matagorda Bay and repeatedly drop heavy rain that totals over a foot in isolated spots. If this materializes, it would lead to significant street flooding.

Could any storms turn severe?

We cannot rule out a severe thunderstorm at this time, but the overall risk appears low.

Will it continue to rain into the weekend?

A few lingering showers are possible Saturday morning, and we currently have your rain chance at 20%. On Sunday, another storm system will approach from the north, and that could sneak in a line of thunderstorms late in the day. Your chance of getting measurable rain for Sunday is currently at 30%.
