| Area Forecast Discussion National Weather Service Lake Charles LA 1237am CDT Tuesday July 21 2026 (Today through Monday) Issued at 1230am CDT Tuesday July 21 2026 Interesting set up with the newly anointed Tropical Storm Berth over the northeast Gulf with a strengthening upper level over the Rockies. Shear and drier air is making for a lopsided Bertha with a majority of the convection on the south side of the storm. Over the immediate area, dry air was noted with the precipitable water on the 21/00z upper air sounding at KLCH at near 1.30 inches. Over the next few days there will be a battle between the strengthening upper level ridge from the Rockies building into the central US and the tropical system Bertha. Steering currents are expected to take Bertha eventually westward near or just inland of the coast of the north central and northwest Gulf. First things first, and in the immediate term, heat will be the issue. Looks like a combination of subsidence and sinking air from the building upper level ridge coming down from the rockies, and the subsident outflow on the outer west side of Bertha will bring very hot air temperatures with highs near triple digits. Meanwhile, some low level rich Gulf air will be trapped in place. Therefore, expect max afternoon heat index values on Tuesday afternoon to be around 110F degrees and in heat advisory criteria. For Wednesday, as the low level moisture increases further and significant mixing does not occur, the heat index has the potential to be higher with the heat risk noted at a Major (3 out of 4) to extreme (4 out of 4) level. As we enter Thursday into Friday, what track and strength of Bertha will be the main influence on the weather. Consensus shows that shear and dry air will eventually win the battle with the official forecast showing a weakening system along or south of the south central and southwest Louisiana coast. All indications are that the system will be asymmetrical with the strong northerly shear pushing any heavy precipitation to the south side of the storm along with the stronger winds. There may be a potential for some stronger showers with high rain rates right along the coast on Thursday. Bertha is expected to dissipate by the weekend with the upper level ridge becoming the main weather player that will bring limited rain chances and hot conditions. 07/ Marine Issued at 1230am CDT Tuesday July 21 2026 High pressure over the northwest Gulf and the circulation around Tropical Storm Bertha will bring modest west northwest winds into Wednesday. Marine conditions for Wednesday night through Friday will depend on the eventual track and strength of Tropical Storm Bertha as it moves just inland or over the northwest Gulf. All marine interests should continue to monitor updates on Tropical Storm Bertha. Fire Weather Issued at 1230am CDT Tuesday July 21 2026 Hot and humid conditions are expected across the region through midweek. Afternoon minimum RH values will be in the 40 to 60 percent range. Tropical Storm Bertha will approach the area on Thursday. At the moment this system is expected to be asymmetrical with a majority of the higher winds and rain amounts to the south of the track of the center.
