| Area Forecast Discussion National Weather Service Lake Charles LA 226pm CDT Tuesday May 12 2026 ...NewARINE,Fire Weather .KEY MESSAGES... - Drier conditions today will continue for the remainder of the week as an upper level ridge builds in. - Temperatures will trend warm in the upper 80s toward 90°F through the remainder of the work week. - Winds out of the north will become light and variable tomorrow with onshore flow returning Thursday night thus keeping afternoons feeling rather muggy into the upcoming weekend. (This evening through next Monday) Issued at 211pm CDT Tuesday May 12 2026 A shortwave developing over the Great Lakes region will amplify south along the Ohio Valley through Wednesday night. This pattern helps direct dry upper level flow southward from the midwest down locally across the TX / LA coast. Being at the fringe of this downstream disturbance, weather is expected to remain dry with winds out of the north easing tonight and Wednesday. Surface moisture will allow some mix of diurnal cumulus, though to a lesser extend Wednesday as surfaces begin to dry out. Main headline for the short term is a gentle warm up to the upper 80's Wednesday and Thursday. Some locations may be touching close to around 90°F. High pressure expected to broaden over the eastern CONUS Thursday allowing onshore flow to become established by the late afternoon. This influx of Gulf moisture under a steady ridge cap will increase afternoon RH, making surface conditions a little more muggy toward the end of the work week. Likewise evening lows will trend in the mid 60s to low 70s during this period along with dewpoints. Forecast remains quiet in terms of active weather, or any precipitation for that matter through Sunday morning. Guidance has backed off on isolated Probability of Precipitation at the end of the forecast period and this was largely expected during last night's forecast given the large subtropical ridge buckling north of Mexico rest of this week. This ridge axis will shift overhead by the weekend as it broadens. Nearing meteorological summer, it is possible that we may start seeing more seabreeze isolated activity soon, but confidence in that this weekend remains very low. By Monday surface high pressure begins to build across the western Atlantic and SECONUS. Guidance suggests a shortwave trough will develop over the Pacific NW and rotate through the northern Plains. Locally, the only affect may be a slight increase in gradient winds due to the strengthening high pressure downstream and increase southerly flow off the Gulf. Thus, a fairly dry forecast is expected into early next week. Kowalski / 30 Marine Issued at 211pm CDT Tuesday May 12 2026 Current conditions are benign, with waves below 3 feet and winds from the north at around 5 knots. Winds will remain light and variable from tonight through Wednesday as high pressure settles in overhead. By the end of the week, the high pressure will shift to the east, and winds will be onshore at around 10 knots. Waves will remain below 3 feet through the end of the week. No showers or thunderstorms are expected during the week. Fire Weather Issued at 211pm CDT Tuesday May 12 2026 Drier air will filter into the region through Thursday as subsidence aloft builds. 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-likely offering a slight increase in afternoon MinRH through the weekend. At this time, forecast remains dry w.r.t. to rainfall through Saturday. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None. GM...None. |
