@pineywoodsweather: A developing weather system will bring an increasing threat of heavy rainfall and flash flooding across South Texas on Sunday. As an upper-level disturbance approaches from the west, deep Gulf moisture will combine with a slow-moving cold front, supporting widespread showers and thunderstorms. Rainfall totals of 2 to 4 inches are possible, with locally higher amounts. The greatest concern stretches from San Antonio southward through Eagle Pass and the Rio Grande Valley toward Brownsville. The Weather Prediction Center has issued a Level 2 out of 4 Slight Risk for excessive rainfall, with localized flash flooding possible, especially in urban areas. #texasweather #WeatherTok #texashillcountry #southtexas #america
