McAllen is waking up under mostly cloudy skies and muggy air around 75 degrees Friday morning, with showers and thunderstorms likely through the afternoon. Temperatures should climb to about 83 degrees before northerly winds and scattered downpours reshape the weekend forecast.
Friday Rain Fades By Evening
The National Weather Service Brownsville office puts the chance of rain at 70% Friday, with the best odds before 5 p.m. New rainfall amounts could range from a quarter-inch to a half-inch, while north winds run 5 to 10 mph, according to the National Weather Service.
Rain chances ease Friday evening, but a few showers could return after 11 p.m. Friday night as temperatures settle near 70 degrees. Saturday starts warmer again, with a high near 83 and a 40% chance of showers and thunderstorms.
Weekend Rain Could Turn Heavy
The weekend forecast is now notably wetter than the outlook described in Hoodline’s earlier update. Showers and thunderstorms are likely Sunday, when McAllen could see a high near 80 before temperatures fall into the 70s during the afternoon.
Forecasters expect widespread rainfall across Deep South Texas from Saturday through Monday, with common totals of 1 to 3 inches and locally higher amounts possible. The region is under a marginal risk for excessive rainfall from Saturday morning through Monday morning, meaning isolated flash flooding could develop where heavier showers repeatedly hit the same area.
Cooler, Quieter Weather Arrives Next Week
Showers continue into Monday as temperatures cool. Rain chances drop sharply Tuesday, when McAllen should reach about 77 degrees under mostly cloudy skies, followed by a high near 79 on Veterans Day.
Drivers and weekend planners should allow extra time during heavier showers and never attempt to cross a flooded roadway. The unsettled pattern should gradually loosen its grip after Monday, but cloudy skies are expected to linger through midweek.
