The near-term forecast for Houston is not great, with on-and-off rain chances likely throughout the weekend and persisting into early next week, along with muggy weather. But none of these rains should be too extreme. And by the middle of next week the forecast begins to look markedly better for us after a long, long summer.
Friday
The radar remains largely quiet this morning, with a few rain showers sprinkled offshore. Conditions should be similar to Thursday, with partly sunny skies and scattered showers. As the forecast map below suggests, where rain does fall today it should be fairly moderate in nature, measuring only a few tenths of an inch.

Unfortunately, it will be another warm and humid day, with high temperatures pressing up near 90 degrees, and likely hitting that mark under full sunshine.
Saturday
Another day with partly sunny skies, scattered showers, and warm temperatures. However, if you have outdoor activities planned on Saturday I’d be fairly optimistic at this point as forecast models indicate we’ll see some slightly drier air aloft. I’d have a plan for spotty showers that may pop-up, but as of now it does not appear likely that we’ll see too many prolonged showers over the Houston area.
