Discussion
As a cold front approaches the area, this low pressure system continues to move NE through Louisiana. Rain chances will remain high due to this system. Once we begin to see some clearing, this afternoon, we will begin to see pre frontal convection and scattered showers and thunderstorms. So, these two features combines are bringing prolonged rain chances for our area. That front will move through, late tonight and early tomorrow morning. After it moves through, we will see clearing skies as a ridge of High Pressure moving continues to move into our area. The good news is that Cooler, more pleasant conditions are on the way.

For the rest of the day
Expect mostly cloudy to overcast skies and gradually tapering rain chances through the midday and afternoon hours. Highs will only climb into the lower 80's due to the abundant cloud cover and prolonged rainfall event. Winds will remain light and variable, becoming light to moderate and out of the NE. Overnight, we will see another round of rain as a cold front moves through the area.

For the rest of the 7day planner
After this system and front push through, we will see gradually clearing skies and tapering rain chances. Tomorrow, skies will become mostly sunny with highs in the lower 80's. The next several days will be very comfortable with a cool start as some cooler and dry air moves into Central Louisiana. Through the end of the week, a ridge of high pressure will heavily influence our area. This weekend will bring with it a slight chance for rain, coupled with seasonable conditions.

TODAY...Expect High Rain Chances (90%) with .25-.75" of rainfall expected. A Low Pressure system and cold front will keep temps low and these rain chances high. Some areas may see 1-2" of new rainfall.Highs 78-84. Variable winds, becoming light to moderate and out of the NE.

MONDAY NIGHT...Mostly cloudy skies and high rain chances continue (40%), but rain chances will begin to fall. Lows 63-69 with a light and variable wind.
