      Hot then you're cool: Weekend weather changes expected

      RGV Through the Weekend:

      The calendar may say fall, but it feels more like late summer in the Rio Grande Valley as of late.

      Temperatures hitting the 90 TMs will continue as we head through your Saturday ahead of an approaching cold front.

      High pressure will continue to dominate the region and provide a mix of sun and clouds through the morning with more in the way of sunshine through the next few afternoons.

      It is also helping to pull in winds out of the southeast, with a deep pool of Gulf of Mexico left in its TM wake.

      The bad news: you TMll have to deal with the heat for at least 72 more hours.

      The good news: Saturday evening, a cold front will approach the Valley from the north and provide lift, and with a good amount of moisture in play, we could see showers and thunderstorms along the leading edge and slightly after into Sunday.

      By Sunday afternoon, a drier and cooler air mass settles in, so expect a high only in the upper 70 TMs to near 80 with cloudy skies!

      Lows bottom out in the 60 TMs for a few days with highs in the mid-upper 80 TMs by early to the middle of next week. Watching the Tropics:

      We are also watching an area in the tropics that has the potential for development, scheduled to impact the southeastern states over the weekend.

      The area of low pressure moving between the Yucatan Peninsula of Mexico and Cuba is expected to continue its TM north-northwesterly path.

      The National Hurricane Center currently give this a 70% chance of development, with the possibility for it to strengthen into Karen. Current models take the system anywhere from Louisiana-Florida by the end of the weekend.

      This could mean higher swells at our beaches this weekend, with rough surf possible.
