FXUS64 KLCH 211727 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1227 PM CDT Sat Mar 21 2026 ...New AVIATION... .KEY MESSAGES... - A warming trend to continue for most of the forecast period. - High temperatures will be in the mid 80s to near 90 across interior SETX and CenLA this weekend and early next week. - Dry conditions continue, with no rain expected for the remainder of the forecast period. && .SHORT TERM... (Today through Monday night) Issued at 1233 AM CDT Sat Mar 21 2026 Somewhat cool albeit humid conditions with temps in the 50s to 60s and near matching dewpoints. As of 05Z, only a few areas of dense fog were noted via satellite and obs sites. This is expected to change with patchy to dense fog likely for most of the CWA. We could see visibilities once again fall into dense fog advisory criteria. Regardless of issuance, one should be cautious while commuting this morning. Fog will burn off shortly after sunrise. A surface high pressure will meander east and south of the forecast area through the remainder of the period with southerly flow prevailing through the next several days. Aloft, a strong ridge over the desert SW will ever so slightly weaken going into the work week as it drifts SSE. This ridge in combination with a trough over the Atlantic coast will allow for northerly to northwesterly flow to prevail aloft. We can expect the warming trend to continue as daytime highs rise (and overnight lows fall) to about 10 degrees above normal going into the consecutive work week. && .LONG TERM... (Tuesday through Saturday) Issued at 1233 AM CDT Sat Mar 21 2026 From the mid week period to the end of the week, the upper ridge will be over the Desert SW, heading eastward into TX. At the surface, areas of high pressure will be over the east coast and Gulf. Despite the stream of southerly flow continuing, showers are not expected. A weak and dry cool front is projected to progress through then slow and bisect the CWA as it begins retrograding. This will provide no real relief in the way of cooling. For the rest of the long term, similar temperature conditions and lack of rain will prevail. && .AVIATION... (18Z TAFS) Issued at 1223 PM CDT Sat Mar 21 2026 Southerly flow will persist during the period bringing low level moisture below a cap in the atmosphere. This will allow for low clouds and patchy fog to form at night with the fog and low clouds gradually lifting during the morning hours. Conditions are expected to be mainly MVFR at all terminals between 06z and 15z, however some lower visibility with some stronger fog probs at KLCH may bring some IFR/LIFR conditions between 22/09-13z. 07/Rua && .MARINE... Issued at 1233 AM CDT Sat Mar 21 2026 Light mainly S to SW winds and low seas will continue through the weekend into early next week as surface high pressure lingers to our east. Ridging building in aloft will keep dry conditions in place, with no precipitation expected through the forecast period. && .FIRE WEATHER... Issued at 1233 AM CDT Sat Mar 21 2026 Warm and dry conditions prevail through the weekend into early next week as upper ridging builds across the country. MinRH values will generally range from the low to mid 40s for inland locations, and from the upper 40s to upper 50s for areas along/south of I-10. While moisture slowly returns through the period, no rainfall is expected for the foreseeable future. && .PRELIMINARY POINT TEMPS/POPS...
