| Area Forecast Discussion National Weather Service Lake Charles LA 1218pm CDT Tuesday Jun 30 2026 (Today through Monday) Issued at 1225am CDT Tuesday Jun 30 2026 Latest water vapor imagery, along with regional upper air analysis, show a rather strong upper level ridge centered over the Lower Mississippi Valley with dry and subsident air in place. However, it looks like the very dry air and the dense dust plume associated with a Saharan Air Layer (SAL) is beginning to move west into Texas. This upper level ridge will begin to shift to the northeast on Tuesday with the dust plume from the SAL (Saharan Air Layer) moving away from the forecast area. Although still enough dry and sinking air that any shower activity during the afternoon will be very isolated along the seabreeze. Again on Tuesday, with the lack of convection, air temperatures will be in the low to mid 90s. Some mixing will take place during the afternoon that will bring dew points down into the low to mid 70s with the apparent temperature from 100 to 107 degrees, which is below local heat advisory policy, with the area outlined in a moderate heat risk from WPC, which is level 2 out of 4. The upper level ridge will become centered over the Mid-Atlantic states on Wednesday. An inverted trough feature will rotate around the periphery of the upper level high and into the forecast area. This will provide a weakness to develop aloft and help enhance diurnal and sea breeze showers and thunderstorms that will likely diminish by sunset with the loss of daytime heating. For the remainder of the week into the Holiday Weekend, the upper level ridge will remain off to the northeast of the forecast area, allowing moist southeast flow around it and some what of a weakness aloft. Therefore, diurnal and sea breeze showers and thunderstorms can be expected. The activity again will likely diminish after sunset and before evening holiday festivities (fireworks) take place. The usual hot and humid summertime conditions are expected, especially away from the convection. Daily afternoon max heat index ranging from 100 to 107 degrees, with at least a moderate heat risk which is level 2 out of 4, and means affects may occur to those who are sensitive to heat, especially those without cooling and hydration. Therefore, over the holiday, watch out for the lightning during the daytime, hear thunder roar go indoors, and take it easy with the heat. 07/ Marine Issued at 1225am CDT Tuesday Jun 30 2026 A weak surface high across the northern Gulf will keep mainly light southerly winds and low seas in place through the end of the week. The chance for showers and thunderstorms will return on Wednesday for the nearshore waters, as well as the coastal lakes and bays. Fire Weather Issued at 1225am CDT Tuesday Jun 30 2026 Typical low level moisture will be found across the area on Tuesday with afternoon minimum relative humidity values in the 50 to 60 percent range. However, any significant chance for shower activity and rainfall will not begin until Wednesday as the upper level high breaks down. Other then some lightning activity possible by Wednesday, no fire weather concerns are anticipated through the period. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None.
