Today will be a nice and cool day, but do not get used to it. High pressure will move over us, and that will make it partly cloudy as high clouds move us the region. Highs will be in the upper 50s. Tonight will become cloudy and it will stay cool/chilly. Low temperatures in the lower 40s north and upper 40s south will actually occur near Midnight, and then they will rise through the night. 
Our wet weather pattern will begin on Saturday. The area of high pressure will move east of Louisiana, and this will bring back the southerly flow over us. We will warm up and have plenty of Gulf Moisture stream over us. Plus, we will see plenty of Pacific Moisture move over us aloft as an upper-level low moves from Baja California toward the Rockies. This will all lead to scattered showers and thunderstorms starting by Noon and they will last through the day and night. Some of the rain could be heavy at times. Highs will be in the upper 60s.
If you are headed out to any New Year's Eve parties, you better plan for rain. We will have scattered showers and a few thunderstorms for Midnight. Temperatures will be in the upper 60s. More rain will occur overnight with lows staying in the upper 60s.
New Year's Day will continue to be soggy. However, it looks like the bulk of the rain will occur in the morning until Noon. Then we will have just spotty showers through the afternoon. Highs will be in the mid 70s. More heavy rain returns on Sunday Night with lows in the 60s. 
Even more heavy rain is expected throughout Monday with numerous showers and thunderstorms. Some of the storms could become strong at times. Highs will be in the mid 70s.
**Rain totals between Saturday and Monday could be around 3 to 5 inches. This will likely cause local rivers on the Northshore to rise to their flood stages. Some street flooding will be possible all weekend too. Keep aware of the heavy rain event expected this weekend, and stay tuned to WWL-TV for updates! **
