McAllen started Monday under cloudy, damp skies near 66 degrees, with showers and thunderstorms expected to push temperatures toward 79. The rain chance is around 80%, and the bigger concern is not just getting wet: already saturated ground could make localized flooding easier across the Rio Grande Valley.
Flood Risk Remains After Sunday’s Soaking
The National Weather Service in Brownsville says another 1 to 2 inches of rain could fall across the area through Monday night, with isolated pockets reaching 4 inches. Additional downpours may cause flooding, especially in spots that picked up heavier rain Sunday, when the region saw widespread soaking conditions.
Showers and thunderstorms are expected through the morning and into the afternoon, although rain chances should gradually ease later Monday. The official forecast still keeps rain in the mix through the day, so drivers should leave extra time, avoid water-covered roads and never cross a flooded roadway when the depth is unclear, according to the National Weather Service in Brownsville.
More Showers Linger Into Tuesday
Rain chances decrease Monday night, with mostly cloudy skies and a low near 69. Tuesday stays mostly cloudy with a 30% chance of showers and a high near 79, followed by another chance of rain Tuesday night and a low around 70.
The unsettled stretch follows the weekend flood threat previously outlined by Hoodline. With the ground already holding plenty of water, even a lower-end shower can create problems in drainage-prone areas.
Clouds Finally Thin Later This Week
Veterans Day stays cloudy and warm, with a high near 80 and only a small rain chance. Thursday remains mostly cloudy near 78, but Friday is expected to turn sunny near 78.
The weekend looks warmer, with Saturday bringing a 40% chance of showers and thunderstorms and a high near 83, followed by a slight rain chance Sunday and a high near 82. Saturday could also bring east-southeast winds gusting as high as 25 mph, so outdoor plans may still need a little flexibility.
