San Antonio faces rainy stretch with Halloween showers possible

San Antonio residents should brace for a week of unsettled weather. The National Weather Service forecasts rounds of showers for the region multiple times before the weekend ends.

Rain is possible on Tuesday, Thursday, Friday, and Saturday. The highest probability of precipitation falls on Thursday and Friday. More than half the region could see showers on both of those days. Forecasters note that flash flooding remains a possibility for those two dates, though the outlook will sharpen as the week progresses.

Halloween weather looks manageable for outdoor activities. A slight chance of showers exists during the day, but rain should clear by nightfall. Temperatures at trick-or-treat hour are expected to reach the mid-70s. This mild profile suits costumes ranging from princesses to video game characters.

The National Weather Service issued a statement detailing the shift in conditions. "There still may be enough lift for isolated showers Friday night and Saturday. Dry weather will return for Saturday night through Monday. With cloudy skies and rain, temperatures will be cooler Thursday and Friday with highs mostly in the 70s. The weekend should be warmer with less cloudiness and mainly dry weather," the service said.

Current rainfall totals at San Antonio International Airport stand at nearly 30 inches since January 1. This figure is two inches above the historical average for this time of year. Bexar County has drifted back toward drought conditions following a wet July and the remnants of Hurricane Polo in September.

October marks the start of the fall season for the city. An increasing number of cold fronts will arrive over the coming weeks. This week brings mild temperatures, with highs hovering just above or below 80 degrees and early morning lows in the 60s.

Weather records indicate the city's first freeze typically occurs around Thanksgiving. This benchmark falls a few days on either side of the holiday.
