McAllen is starting Sunday under mostly cloudy skies with temperatures around 75 degrees, but the day is headed toward another 94-degree afternoon. Patchy fog may linger into Sunday morning before dissipating by mid to late morning, then partly sunny skies take over, with almost no chance of rain.
The hot stretch is not done yet. Sunday night stays mostly cloudy with a low near 75, followed by a mostly sunny Monday that could reach 95 degrees.
Heat And Gusty Winds Build Monday
Monday’s south-southeast winds will run 5 to 12 mph, with gusts as high as 23 mph. Tuesday remains mostly sunny and hot near 94 degrees, but a developing cool front will bring a small chance of showers and thunderstorms, especially Tuesday night.
The National Weather Service Brownsville says the front should bring cooler, drier air behind it, with no widespread flooding expected. The weather service discussion gives low-grade 20% to 40% chances of showers Tuesday and Tuesday night, so this looks more like a passing possibility than a washout.
Wednesday Brings A Noticeable Cooldown
Wednesday should be sunny with a high near 86 and a low around 64 Wednesday night, offering the most obvious break from the early-November heat. Temperatures rebound to about 91 Thursday, then ease to 87 Friday and 84 Saturday.
A second front could arrive next weekend, bringing another slight chance of rain showers and thunderstorms Saturday. For anyone heading toward the coast, the weather service is also watching for isolated minor coastal flooding near high tide through 7 a.m. Monday, making a beach-day check worthwhile even though inland McAllen stays dry.
The latest outlook extends the hot, mostly dry pattern described in Hoodline’s earlier McAllen forecast, while adding a clearer look at Tuesday’s front and the cooler air arriving Wednesday.
