A few showers will dissipate while crossing the Rio Grande in Starr and southern Zapata County by 8 PM. Otherwise, moonlit skies will dominate, with near calm winds and the long night allowing temperatures to drop into the lower to mid 70s...right around the average for late September. Light winds and slight seas will prevail over the Gulf, with just a slight chance for a late night shower or storm beyond 20 nautical miles east of Port Mansfield to Baffin Bay.
