The National Weather Service reports there’s a 50 percent chance of rain on New Year’s Eve and an 80 percent chance of rain on New Year’s Day.

The rain is being brought in by an upper-level, low-pressure system that is expected to move toward the Rio Grande Valley. Cloud cover will be on the increase Tuesday and a few light showers may clip the Lower Valley as early as Tuesday afternoon.

Rainfall amounts of about 1 inch are expected in the Brownsville area while South Padre Island could receive 1 inch to 1 1/2 inches. The rest of the Valley could receive a 1/2 inch to 1 inch of rain. Periods of moderate to heavy rain could occur early New Year’s Day. Some areas could hear a few rumbles of thunder.

The NWS reports the main impact from the rain will be slick roads as the rain begins “in earnest” during the early morning hours on Wednesday. Localized ponding or nuisance flooding could occur in lower-lying areas by Wednesday afternoon.

The temperatures on New Year’s Eve will be in the mid 50s to lower 60s. The highs on New Year’s Day will be in the 60s or near 70 along the coast, although “an all day soaker” could keep the temperatures a few degrees cooler.

The rain chances will taper off on Thursday, ending in most areas.
