From the National Weather Service in Brownsville

The low pressure system located over the southwestern Gulf of Mexico has decreased and remains disorganized, according to the National Weather Service in Brownsville. This is the system that is expected to bring moderate to heavy rain today and Wednesday to the Rio Grande Valley.

The NWS says the system could briefly become a tropical depression before moving inland over northeastern Mexico later today.

For today, there is a 40 to 60% chance for rain in Hidalgo and Starr counties. For Cameron and Willacy counties there is a 60 to 80 percent chance for rain. There is a possibility for heavy rain at times.

The rain and cloud cover will help reduce afternoon temperatures about 5 degrees cooler than the previous few days, with highs in the upper 80s to mid 90s.

Tuesday’s expected high temperatures: Brownsville 90, McAllen 92 and South Padre Island 87.

On Wednesday, highs will range between 90 and 96. There will be a 60 percent chance for rain, with the best chance coming in the lower Valley.
