McAllen is waking up Thursday under cloudy skies and muggy air, with temperatures in the low 70s before a warmer, wetter afternoon. Showers may arrive by late morning, and the forecast calls for a high near 87 degrees with thunderstorms possible later in the day.

Rain Chances Rise After Lunch

A few showers could develop later Thursday morning into the afternoon, with the better chance for showers and thunderstorms arriving during the afternoon. The National Weather Service in Brownsville puts the overall rain chance near 50%, while light winds are expected early in the morning.

Most locations should see less than a half-inch of rain, though isolated heavier downpours could produce more. There are no watches, warnings or advisories listed for the area, but drivers and anyone with outdoor plans should keep an eye on changing skies through the afternoon.

Mostly Sunny And Hotter Through The Weekend

Friday looks mostly sunny and warmer, with a high near 90 degrees and an overnight low around 69. Saturday should also reach about 88 degrees, with only a slight chance of rain after 1 p.m. and wind gusts up to 24 mph.

Sunday stays partly sunny with a high near 87, followed by another warm, mostly sunny Monday near 88. Rain chances return early next week.
