A few storms possible Thursday, better chance for rain Friday

HOUSTON, Texas (KTRK) -- A few thunderstorms could pop up Thursday afternoon, but there's a slightly better chance you'll get rain on Friday as a trough of low pressure blows in from the Gulf.

Temperatures will dip into the mid 70s Thursday morning then heat up into the mid 90s before thunderstorms start to form. While many will stay dry, those that do get a storm could get a quick inch of rain along with frequent rumbles of thunder. Any storm that pops up should fizzle after the sun sets.

What are my chances for rain Friday?
Friday's rain chance for Houston is 40%, but there's an even better chance of rain southwest of Houston toward Matagorda Bay. That's because deeper tropical moisture from a trough of low pressure will blow into the middle Texas coastline. It won't take us much heat to get the storms going, so temperatures will peak early in the mid 90s then cool into the 80s and even 70s where it rains heavily.

What are we expecting this weekend?

More heat! A few afternoon downpours are possible Saturday, but a heat dome should squash the clouds and rain chance Sunday down to 20%. This will send high temperatures back toward 100-degrees.

When will the next summer front impact us?
At this time it appears the front will impact us after the weekend, approaching Monday night and arriving on Tuesday. The timing could shift a day earlier or later, but when it does arrive, widely scattered downpours are possible followed by below "normal" temps with highs in the low 90s and lows in the low 70s.
