| Area Forecast Discussion National Weather Service Lake Charles LA 1246pm CDT Tuesday May 12 2026 (Today through Monday) Issued at 1226am CDT Tuesday May 12 2026 A shortwave trough is exiting east off the Coast of New England today while upstream troughing has the frontal boundary pushing east of the Mississippi Delta. With high pressure descending from the Central Plains mid level water vapor analysis illustrates dry air filtering into the area, locally over Southeast TX and Southwest LA. 12th/00Z sounding has also captured mid and upper levels beginning to dry out. Partly cloudy skies can be expected while north winds mix antecedent surface moisture into the lowest 1-2km AGL. Despite the subsidence aloft, still expect conditions to remain rather muggy through the day while climbing in the low to mid 80s. Dry weather is forecast to take place across the area through much of the remaining work week ahead. Northerly winds will ease Wednesday, especially for interior locations and may occasionally become calm or variable light breezes. Afternoon RH will decrease. However, as one would expect with a building subtropical ridge, temperatures are forecast to climb to the upper 80s by the midweek, possibly reaching 90F. While this weather isn't comfortable wrt humidity and heat, it will provide an opportunity for many folks, like your local meteorologists, to cut those lush lawns that you can almost hear growing after all the rainfall received over the past several days. Surface high pressure will begin to shift over the eastern CONUS Thursday leading to onshore winds becoming established into Friday. Gulf moisture will lead to muggy afternoons again toward the end of the week with highs hovering in the upper 80s to near 90F through the following weekend. Guidance attempts to bring some rainfall back to area by late Sunday or Monday as the upper level ridge begins to broaden, potentially allowing some diurnally driven isolated convection to occur. That said, these are low end chances and subject to change as guidance refines the long range pattern. Kowalski / 30 Marine Issued at 1226am CDT Tuesday May 12 2026 A light offshore flow will persist into early Wednesday. Winds become light and variable by Wednesday afternoon as high pressure settles overhead, followed by a return of southerly flow by the later half of the week. Dry conditions are expected through Friday. Fire Weather Issued at 1226am CDT Tuesday May 12 2026 Drier air will filter into the region today, however, recent rainfalls will keep surface RH generally above 50%. As subsidence builds aloft, afternoon minimum relative humidity values will range into the 40-60% range for the remainder of the work week. Breezes may be calm or light and variable at times. Southerly winds become established by Friday as high pressure shifts eastward. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None. GM...None. |
