Tonight: Another night of cold temperatures with lows in the mid-to-upper 30s. Clouds will begin to filter in the region overnight. Depending on how early clouds move in, our northern parishes and Southwestern Mississippi counties could see lows closer to freezing if clear skies persist a little longer.

Tomorrow into Tuesday: After a cold start, clouds will increase more so in coverage ahead of a surface low that will develop near the Texas Coast. It will track close to the Louisiana Coast during the day as it moves generally eastward. Winds will shift to become southwesterly during the day allowing for some warm air advection.

Dewpoints will begin to increase to the 50s and 60s allowing for more moisture in the atmosphere. Highs will reach into the high 50s and low 60s during peak heating hours. Along with this system, scattered showers and isolated storms will move through. Strong to severe storms are possible but should remain closer to the coast. The more unstable environment will be in the warm sector of the front, which looks to remain on the coast and over the Gulf waters.

Showers will begin to move into the area tomorrow evening and roll away by sunrise on Tuesday. Because there is increased atmospheric moisture, heavy rain is likely with totals between 1″ and 2″ and locally heavier amounts.

As the front makes its way eastward, temperatures will began to drop and might rebound a touch into the mid 50s by the afternoon. During the evening, temperatures will fall once again. 

Beyond: After the frontal system moves past, winds will be from the north ushering in more cold air. Morning lows range in the 30s and low 40s with highs in the 50s. Some rain is possible late in the week, but confidence is low for now. 

Tracking the Tropics: Nicole is out of the way now and there is no development expected over the next 5 days in the Atlantic.
