After a mostly cloudy start to the day in the Rio Grande Valley, expect Thursday afternoon to be partly cloudy with a slight chance of rain.
High temperatures will reach the lower 80s. Both Brownsville and McAllen will be 82. South Padre Island is expected to reach 70.
Dense fog along the coast is expected to become patchy and persist through most of the day.
Looking ahead, expect a warm weekend. Some areas of the Valley will reach the upper 80s on Sunday. On Monday, however, a cold front will move in, dropping temperatures into the 40s.
