San Antonio Rain: NWS Forecasts Midweek Showers and Halloween Drizzle

San Antonio residents should prepare for a wet week with multiple shower opportunities, according to the National Weather Service. A rainy pattern is developing that brings precipitation risks to the region on Tuesday, Thursday, Friday, and Saturday.

The heaviest rain chances are expected on Thursday and Friday. More than half the region could see showers on both of those days. While flash flooding is possible, the forecast will become clearer as the week progresses.

Temperatures will drop due to cloudy skies and rain on Thursday and Friday, with highs mostly in the 70s. The weekend should be warmer with less cloudiness and mainly dry weather. Dry conditions are expected to return for Saturday night through Monday.

A statement from the National Weather Service noted that there may be enough lift for isolated showers on Friday night and Saturday. The agency said, "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."

Trick-or-treaters can expect a very slight chance of showers on Halloween. Any rain should be gone by nightfall when porch lights come on. Temperatures at that time should be in the mid-70s.

Rainfall totals at San Antonio International Airport have reached nearly 30 inches since Jan. 1. This amount is just two inches above the normal average for this time of year. Bexar County has been backsliding into drought conditions after a rainy July and the remnants of Hurricane Polo in September.

The city's first freeze usually occurs around Thanksgiving, give or take a few days. October marks the start of fall weather with increasing cold fronts. This week, highs will hover just above or below 80 degrees, and early morning lows will be in the 60s.
