Heat Stress and On and Off Rain All Week – Weekly Outlook for MS/LA/AL 6/23/24

To end off June, we’re going to feel plenty of heat for the rest of the week. The National Weather Service has already put out a Heat Advisory for the majority of Mississippi and parts of Louisiana and Arkansas. To top this off, we’ll have several rain chances throughout the week with a possible washout on Wednesday into Thursday.

To start off the week, we’ll see temperatures rise into the mid to upper 90s and the heat index rise into the low and mid 100s. Areas in the MS/LA/AR Delta will get the worst of the heat, but other parts of Mississippi and Alabama won’t be free from the heat stress.

The cold front over the mid-South will stall and give us some scattered thunderstorms on Monday and Tuesday.

As the upper level ridge begins to retract on Wednesday, an enclosed surface low is forming out from the Plains and moving due East into the Southeastern US. The low is fairly tight and will bring plenty of convection and precipitable water with it, however it will start to dissipate as it moves towards the ridge. We may see some heavy pockets of rain out of the deal when it moves in.

From Thursday into the weekend, we’ll still see the heat stress with the heat index reaching the mid-100s each day. The rain chances will be diurnal meaning mainly afternoon thunderstorms. Another cold front will move in on Thursday into Friday, but the following one will stall out and cause some storms to develop on Sunday.

Overall, a hot and potentially stormy week ahead. Be sure to drink plenty of electrolytes, wear your sunscreen and keep an umbrella just in case.
