Overnight lows in RGV to drop into the 50's

Cooler temperatures are expected across the Rio Grande Valley Saturday night thanks to a cold front that passed through the South Texas region this weekend.

Rain chances will remain in the forecast for Sunday night into Monday as a trough forms off the south Texas coast. The greatest chance for showers will be in the lower valley.

Temperatures will remain at or below average as yet another cold front is expected to make its way to the RGV Tuesday morning, bringing another slight chance for showers to the region.
