HOUSTON, Texas (KTRK) — Rain chances are increasing as tropical moisture surges into Houston on Wednesday. This tropical moisture will remain disorganized, but these storms could drop a quick inch or two of rain that floods streets along with frequent lightning strikes that could temporarily knock out the power. This type of pattern also can produce funnel clouds and waterspouts in the morning near the coast.
These storms will start to develop during the morning commute, and this early onset of the rain will keep highs for most only in the mid-to-upper 80s. The rain chances will drop during the afternoon from I-10 south, but the storm chances will climb north of I-10 for the afternoon. Those afternoon storms north of Houston could turn a bit stronger like some did late Tuesday. Remember, if you hear thunder roar, head indoors!
How much longer will this wet weather last?
The tropical moisture will start moving away Wednesday night, dropping the rain chance to 40%. By Friday and Saturday, drier air will take over dropping the rain chance to 20% or less. Another wave of tropical moisture will clip us on Sunday to bring the rain chance up to 40%, then the faucet will shut off for the first days of July.
What’s the early outlook for July 4th and the Freedom Over Texas fireworks show?
At this time it looks dry but hot! Temperatures will peak near 100 with heat index values well above 100.
What’s happening in the tropics?
Tropical Storm Andrea, the first storm of the 2025 Atlantic hurricane season formed over the Atlantic on Tuesday. A short-lived storm, it should dissipate by Wednesday. Meanwhile, another storm is threatening to form south of Mexico in the eastern Pacific. For a thorough update and in-depth video on what’s happening in the tropics, head to our tropical update page.
