Tracking storms today and tonight, with lots of sunshine after

It’s a bit of a messy forecast for the greater Houston region Wednesday and Wednesday night, so let’s break it down.
Wednesday
For the most part during daytime hours, the metro area of Houston, including immediately surrounding counties, will experience mostly cloudy skies, with a 30 to 40 percent chance of light to moderate rain showers. In Houston, rains look most likely around noon before a break this afternoon.
However, in the Brazos Valley including College Station, we have concerns later this afternoon, as an atmospheric disturbance migrates northward and combines with an approaching front. At this point, high resolution models point to the potential for some fairly heavy rainfall from mid-afternoon through the early evening. We’d expect some areas to see 1 to 3 inches of rain, with isolated higher totals.

For Houston, itself, stronger storms are unlikely to move into the region before sunset (or later) as a line of showers and thunderstorms pushed through from west to east. I’d guess this line reaches the western part of the metro area between 7pm and midnight, and pushes through the city during the overnight hours. For now, the best chance of storms (mainly a hail and damaging wind threat) appears likely north of Interstate 10. Rain totals of 0.5 to 2.0 inches remain likely in Houston from this system, although I’m not sure whether we’ll see a solid line of storms, or whether it will be broken by the time it reaches Houston.
