A weak cool front has brought slightly drier air to Southeast Louisiana and Mississippi and that will allow over night lows to drop some 5-10 degrees.
Sunshine early Friday will make for a quick warm up, but some clouds will begin showing up later in the day. As low pressure moves out of Texas on Saturday, we'll be windy & warm.
The morning should be mostly dry, but rain chances increase during the afternoon and will be highest after dark through midday on Sunday. Behind this system will be some drier air for Monday and Tuesday but little in the way of cooling.
