McAllen's Friday forecast calls for mostly sunny skies, a high near 90 degrees and only a minimal chance of rain.

Friday Stays Hot And Mostly Dry

East winds will run 3 to 10 mph through the afternoon, making for a breezy but generally manageable day. Tonight will be mostly clear with a low near 70, while southeast winds could gust up to 22 mph, according to the National Weather Service Brownsville.

Saturday Brings A Late Shower Chance

Saturday looks much like Friday for most of the day, with mostly sunny skies and a high near 88 degrees. Rain chances are 20% or less, and east-southeast winds could gust to 25 mph.

Rain Chances Return Next Week

Sunday turns partly sunny with a high near 86, followed by another mostly sunny 87-degree day Monday. Showers and thunderstorms become more possible Tuesday through Thursday, with rain chances around 30% each day after a mostly dry weekend; the shift is a notable update from the earlier McAllen forecast.

A Minor Heat Risk Lingers

There are no watches, warnings or advisories listed for the area, but the National Weather Service notes a minor risk of heat-related illness across parts of Deep South Texas. Outdoor plans should be most comfortable earlier in the day, with water, shade and breaks still worthwhile during the warmest afternoon hours.
