The weather pattern that has kept most of South  Louisiana warm, muggy, and dry for the past week is about to undergo a significant change. The warm and muggy part won't change much but the dry part most certainly will. As the ridge of high pressure that has been blocking storm systems from moving in begins to breakdown we can expect a better chance of rain and the possibility of severe weather over the next couple of days.

The Storm Prediction Center has posted a slight risk of severe weather for much of  Louisiana today. That area of potential severe weather runs the width of the country and is tied to an approaching frontal system. This front is expected to kick up a threat of showers and thunderstorms for Acadiana today. It will then stall just off the coast and continue to be the reason for a chance of rain in the forecast for the rest of the week.

Even though many forecast models show the frontal boundary eventually washing out as it moves through Louisiana there is enough moisture in the air to create thunderstorms. There will also be disturbances forming along this frontal boundary and depending upon when and where they form that could lead to the threat of heavier weather.

The long range forecast from the KATC Weatherlab gives us a chance of showers and thunderstorms each day this week. Temperatures should remain seasonable with afternoon high temperatures reaching the middle 80's. Overnight low temperatures should range from the middle 70's to the upper 60's.
