796 FXUS64 KLIX 031830AFDLIXArea Forecast DiscussionNational Weather Service New Orleans LA130 PM CDT Sat Aug 3 2024...New SHORT TERM, LONG TERM, AVIATION, MARINE....SHORT TERM...(This evening through Sunday night)Issued at 108 PM CDT Sat Aug 3 2024Tonight through Sunday, the lingering frontal boundary slidessouthward into the Gulf, continuing the slightly enhanced rainchances tonight into tomorrow morning. These storms will have mainthreats of brief, gusty winds (40-50mph) and lightning where theyoccur. Locally heavy rainfall will also be a concern for urbanareas inside of storm development. Once these storms slidesouthward, ridging sets up again over our area, and conditions become a bit drier again with only isolated to scattered rain chances forecast for Sunday. As a result, Sunday will once again be hot with little chance for relief. High temperatures are forecast to be in the upper 90s with heat index values between 108and 112 degrees. Therefore, a heat advisory has been issued for our entire area for tomorrow from 10a to 7pm CT. Remember to stay hydrated and wear light- colored, loose-fitting clothing. Also, take frequent breaks if you will be working or spending time outdoors as heat is cumulative! MSW&&.LONG TERM...(Monday through Friday night)Issued at 108 PM CDT Sat Aug 3 2024Monday through next week, the ridge stays in place over our areafor the week. The tropical system will be heading more toward Florida, based on the latest forecasts from the NHC, and so wearen't expecting direct impacts from the system. This means that the hotter and drier weather will persist into next week thanks tothe ridge building over the area. There are even some indicators that we could break a couple heat records, depending on how thingsset up. With only isolated rain chances expected all week, the heat will be the biggest concern for our area this week, lookingat the models. Daily highs will be in the mid to upper 90s withseveral locations approaching 100 degrees for multiple days thisweek. Heat index values daily are forecast to be between 110 and118 degrees for most locations, so heat headlines are likely allthis week. This is very hazardous as heat is cumulative and heatstress builds up over time. So the longer we see high temperaturesand relative humidities, the more stress people's bodies arefeeling each day from the heat conditions. Another thing worthnoting is that overnight low temperatures will not drop below 80degrees all week either, which will just add to the heat stress.This is especially true for urban areas (i.e. New Orleans, BatonRouge, MS Coast) because the heat will linger longer into theevening in these areas due to the concrete/asphalt trapping heatmore readily, resulting in a shorter period of recovery. So,overall, don't expect much rain this week to provide a break forthe heat. And expect very HOT conditions this week, so takeprecautions! Stay hydrated! Take frequent breaks when workingoutdoors or doing outdoor activities, especially from 10a-4p everyday! Wear light-colored, loose-fitting clothing as well ifpossible. And lastly, don't forget to account for your pets! If you are hot, they are hot! Stay coool!
