HOUSTON, Texas (KTRK) — A low pressure disturbance just offshore from Galveston will continue to swing scattered showers through Southeast Texas over the long holiday weekend.
We’re starting the day off in the mid-70s with scattered showers, especially near the coast. Temperatures will warm to near 90, allowing for heavy showers and a few thunderstorm to pop up in the late afternoon hours. Your chance of getting rain is 40%, and most showers should move through quickly from the north and northeast, keeping rain totals generally less than 1/4 of an inch. Rain chances will be higher near the coast, especially from Galveston to the Texas-Louisiana border.

What is the weather outlook for Sunday and Labor Day?
The low pressure over the Gulf of Mexico should start pushing pack toward the upper Texas coastline on Sunday, boosting rain chances to 60%. It is then predicted to move closer to Matagorda Bay by Labor Day, which would put most of Southeast Texas in a very moist tropical flow. That will push the rain chances up to 80%. Have a backup plan in case any day turns into a washout, and at a minimum, know where you could go to seek shelter from a heavy thunderstorm. Of course, when thunder roars, go indoors! Temperatures will remain in check with lows in the mid-70s and highs generally in the upper 80s. Where it rains heavily, temperatures will stay stuck in the 70s.
Are there any cool fronts on the horizon?
We actually see signs that front may enter Southeast Texas toward the end of next week, which would push the tropical moisture into the Gulf of Mexico and drop our rain chances to less than 20%. As the air dries out, highs will again top the 90 degree mark, but lows will push closer to 70 degrees. If the front comes in stronger than expected, we could even get some morning lows in the 60s!
What are you tracking in the tropics?
In addition to the low pressure over the Gulf, we are also monitoring two tropical waves in the Atlantic, one of which has a 40% chance for development over the next 7 days. This wave in the central Atlantic could end up as a named storm in the Gulf of Mexico during the 2nd week of September and bears watching.
