FXUS64 KLCH 081756 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1256 PM CDT Wed Jul 8 2026 ...New DISCUSSION, MARINE, FIRE WEATHER... .KEY MESSAGES... - Isolated to widely scattered thunderstorms possible along the sea breeze this afternoon. - Shower activity is expected to decrease for Thursday and Friday as an upper level ridge briefly builds back in. - A weakness redevelops over the weekend along with deeper tropical like moisture helping to increase shower and thunderstorm activity. - Typical summertime heat can be expected with afternoon max apparent temperatures between 100 and 105 degrees daily with the heat risk at moderate level (2 out of 4.) && .DISCUSSION... (This evening through next Tuesday) Issued at 1250 PM CDT Wed Jul 8 2026 Surface analysis depicts weak high pressure overhead, providing a light southwest to west flow across the forecast area. Aloft, a weakness remains over the Ark-La-Miss, with weak ridging to the west and east. Area radar shows a few isolated showers and storms ongoing along and south of the I-10 corridor this afternoon, with coverage slowly expanding as we move towards max heating hours. The weakness aloft will provide some additional support for convection this afternoon however, it doesn't look like coverage will be quite that of the last few days. Nevertheless, WPC has once again outlined the entire forecast area within the Marginal Risk for excessive rainfall today. With only scattered activity expected this afternoon, the inclusion of this outlook is strictly to cover the possibility of slow moving heavy downpours that could cause very localized flooding issues over more urban areas. Otherwise, it looks like (shocker) another hot and humid afternoon with highs reaching into the low to mid 90s. Tomorrow and Friday, what remains of the weakness aloft continues to break down as ridging to the west and east expand towards each other overhead. As weak ridging become situated across the southern CONUS through the end of the week, it will tamper our daily chance for showers and storms down a bit for a couple of days. While we won't dry out completely, we will see much more sunshine than rain through the next couple of days. Temperature wise, we continue to reach into the low to mid 90s through the afternoon, with heat indices peaking in the mid 100s. By the weekend, POPs ramp up once again as upper ridging shifts west and becomes situated over the Rockies allowing a weakness to develop overhead once again. This weakness aloft together with the seabreeze/diurnal heating will result in more widespread afternoon activity each day from Saturday into early next week. This will keep afternoon highs in the upper 80s to low 90s, with max heat indices in the low to mid 100s. && .AVIATION... (18Z TAFS) Issued at 1212 PM CDT Wed Jul 8 2026 Scattered showers and thunderstorms will continue along/south of the I-10 corridor into this evening, possibly expanding further north later this afternoon as well. Like the last few days, if any of these storms pass over the terminals they will be capable of producing heavy downpours that cause reductions in VIS along with frequent lightning. Outside of these storms, VFR conditions and light and variable winds should prevail throughout the forecast period. && .MARINE... Issued at 1250 PM CDT Wed Jul 8 2026 Surface high pressure will remain stretched from the Atlantic into the northern Gulf through the week. This will keep a light south to southwest flow and low seas in place. Isolated to widely scattered shower and storms will be possible each day, with coverage increasing a bit by the late weekend into early next week as another weakness develops aloft. && .FIRE WEATHER... Issued at 1250 PM CDT Wed Jul 8 2026 No fire weather concerns at this time. Isolated to widely scattered storms are expected today along the sea breeze, however coverage will decrease Thursday and Friday as an upper ridge builds in. && .LCH WATCHES/WARNINGS/ADVISORIES...
