Possible Street Flooding Later Today
A front moving into the region could bring high hourly rainfall rates and rapid street flooding, according to Jeff Lindner, Harris County’s meteorologist. He says, “A weak front will move into the area today and tonight, and stall near the coast or just offshore on Tuesday and Wednesday.”
Slow-Moving Front, Training Cells, Possible Street Flooding
“The slow-moving front is moving southward across north and central TX. Numerous showers and thunderstorms have already formed along it. The air mass in the Houston region will become increasingly unstable this afternoon. Expect numerous, slow-moving showers and thunderstorms to develop across the region,” says Lindner.
“The combination of slow movement, deep tropical moisture, and the potential for training all points toward a heavy rainfall threat this afternoon,” he said.
“The main threat will likely be short-term rainfall rates of 2-3 inches per hour leading to rapid onset street flooding.”

Mainly South of I-10 and Offshore by Tomorrow
Lindner continued, “The front will push toward the coast tonight and may even move offshore on Tuesday. A slightly drier air mass will build into the region behind the front with rain chances focusing near the coast and across Gulf waters later today and tomorrow.”
He sees the main rain chances on Tuesday for areas south of I-10. However, he also predicts much of the activity will be offshore.
Enjoy the slightly drier air mass and “cooler” temperatures behind the front as it washes out by late week. After that, onshore flow will return along with humidity. “By next weekend, heat index values could near advisory levels,” Lindner warns.
Tropics to Pick Up by Mid-August
On an unrelated topic, Lindner sees no concerns for the next 5 days for tropical development in the Atlantic basin. However, Lindner sees signals that the Atlantic basin will become increasingly favorable for development toward mid August.
