Houston’s Dry Streak Ends as Rain Returns for Halloween
Houston’s 35-day dry streak has officially ended, with even more rain anticipated for Halloween. Tropical moisture will move in overnight, bringing isolated showers through sunrise. As temperatures warm after sunrise, rain will increase, with some showers developing into heavy thunderstorms. Though severe weather is unlikely, heavy downpours may lead to waterlogged streets, and strong lightning could cause brief, isolated power outages. A weak cool front moving into Southeast Texas appears likely to stall just north of Houston, keeping rain chances through the evening. While temperatures will reach the 80s, areas with rain will cool into the 70s.
Halloween Trick-or-Treating Weather
Expect a humid evening for Trick-or-Treating on Halloween, but most rain should taper off by the time festivities begin. However, areas near the stalled front could still see rain while the rest of Southeast Texas dries out. Ground conditions will likely be wet even if the sky is clear. Temperatures should mostly stay in the 70s.
Rain Totals for the Weekend
Through the weekend, rainfall amounts of 1-3 inches are likely. Any storm could bring a quick inch of rain, with the highest chances on Thursday and Saturday at 70%. On Saturday, a surge of tropical moisture will sweep through Southeast Texas in advance of a new weather system expected around Election Day.
Election Day Weather
A cool front is expected in Southeast Texas on Election Day, bringing another round of stormy weather. While the exact timing of rain is uncertain, those who want to avoid potential storms may consider early voting on Friday, when rain chances will be lower.
Cooler Weather Ahead
While the front arriving on Election Day could stall through Wednesday, cooler and drier air is expected to follow by Thursday. This should bring temperatures down to seasonal levels, with highs in the 70s and lows in the 50s toward the end of next week.
Tropical Update
We’re monitoring an area in the southwestern Caribbean with a 40% chance of development over the next seven days. This disturbance could eventually enter the Gulf of Mexico, though it would most likely stay far from Texas. For more on tropical developments, check out our daily Tropical Update page.
