Houston is starting Sunday after partly cloudy skies overnight and a low of 62 degrees, with a mostly cloudy afternoon ahead. The high should reach 82 degrees, and rain is not expected as east winds run between 5 and 10 mph.

Mostly Cloudy Sunday, Warm Start To The Week

Sunday night temperatures will settle near 60 degrees. Monday stays mostly sunny and slightly warmer, reaching about 83, before another mostly cloudy night drops to around 66.

Tuesday will remain warm near 81 degrees but mostly cloudy, with only a 5% chance of rain. According to the National Weather Service Houston/Galveston, a few areas north of Houston could see patchy fog around sunrise, though it should clear quickly.

Low Rain Chances Return Before Halloween

Rain chances return early in the week, expanding farther north Tuesday. Wednesday brings a slight chance of showers and thunderstorms after 1 p.m. The chance of precipitation is about 20%, while Thursday should turn mostly sunny again with a high near 82.

Friday will be partly sunny with a high around 80, and Saturday’s Halloween forecast calls for mostly sunny skies, a high near 84 and a 30% chance of showers and thunderstorms. Outdoor plans look generally favorable, but the umbrella may finally earn a little attention by the end of the week.

Gulf Waters Get Rougher Early In The Week

Boaters face a more complicated forecast than people staying on land. Seas are expected to build to 4 to 6 feet Sunday and possibly 6 to 7 feet offshore Monday, with a small-craft caution posted through late Monday night.

Winds and seas could become locally stronger near showers or thunderstorms as Gulf moisture increases. No land-based watches or warnings are listed for the Houston area.
