| Area Forecast Discussion National Weather Service Lake Charles LA 1201am CST Thu Jan 22 2026 .SHORT TERM... (Tonight through Saturday night) Issued at 1124pm CST Wednesday Jan 21 2026 Light shower activity continues to affect much of south LA tonight, associated with a passing surface trough and approaching boundary. Said boundary will sag into the forecast area overnight, becoming quasistationary overhead through the next 24-36 hours. As it meanders nearby it will provide a focus for isolated to scattered shower activity today and tomorrow, amid otherwise cloudy conditions. High temperatures will warm into the low 60s to low 70s this afternoon, while Friday, highs range from the mid 50s to upper 60s. Late Friday into Saturday, we enter a period of high uncertainty as a significant pattern change arrives. First and foremost, there has been a notable shift in the models in regards to when the cold air will arrive, with the newest suite of models bringing the cold air in later than previous. I'm inclined to believe this shift however, at this point I felt it was irresponsible to shift too far to the warm side of things, given the high uncertainty and spread that still exists. Still, you will notice that the forecasted highs for Sat are warmer tonight than previously forecasted, with highs ranging from the upper 30s at Alexandria to the upper 60s at Morgan City. This gives a broad picture of how slowly cold air will be moving in on Sat, with northern parts of the CWA (County Warning Area) significantly colder than the most southern parts. Still, all areas are expected to be above freezing throughout the daytime hours on Saturday, meaning threats for winter precipitation have fallen out of the forecast for this time period. Still, very high rain chances are on tap for Saturday, as a deep surge of moisture spreads into the area and interacts with the cold front both ahead of the boundary as well as behind it. Saturday night brings the biggest question mark of the forecast period in regards to winter weather, as some guidance is still hanging up the coldest air throughout this period. Hoping to see a bit more run to run agreement on that in the coming day or so, but for now I expect the majority of the forecast area excluding lower Acadiana to fall below freezing Saturday night/Sunday morning at least for an hour or two. This will overlap with the continuous overrunning precipitation that is expected to persist throughout the overnight hours into Sunday, leading to some wintry precipitation possibly as far south as parts of the I-10 corridor as we head into Sunday. Granted, this is still a big question mark at this time, even 3 days out. Long Term (Sunday through next Wednesday) Issued at 1124pm CST Wednesday Jan 21 2026 Moving into the long term the temperature uncertainty continues throughout Sunday with models again coming in slightly warmer. This is good news for most of us though, with the majority of the forecast area likely reaching above freezing for at least a few hours on Sunday which should help alleviate any ongoing freezing rain concerns. For now, highs range from 32 degrees at Alexandria to around 50 degrees at Morgan City. What is certain is that precipitation will continue throughout much of Sunday, eventually tapering off Sunday evening into Sunday night, which will likely bring a mixed bag of precipitation types for Sunday. At this point, the highest concern for freezing rain looks to be along and north of I- 190 with concerns decreasing a bit for areas between I-190 to I-10. By Sunday night, the coldest air will have definitely arrived, with Monday morning lows expected to range from the mid teens to mid 20s. In addition, winds will be gusty out of the north as a strong surface high builds into the Southern Plains, resulting in wind chill values in the 5-15 degree range. Chilly conditions continue into Monday however, we should finally get some sunshine peaking through by Monday afternoon along with winds finally relaxing as high pressure begins to settle overhead. Monday night/Tues morning again brings lows in the teens to mid 20s however, wind chill values will be in the same range as winds calm. The remainder of the long term brings a slow but steady warming trend as surface high pressure slides across the SErn US. Temperatures will likely fall below freezing for a few more nigheights for parts of CENLA but for the rest of us low range from the mid to upper 30s, while daytime highs range from the upper 40s to upper 50s. Marine Issued at 1124pm CST Wednesday Jan 21 2026 Light to moderate east to east-northeast winds will continue through Friday, along with occasional shower activity as a boundary lingers nearby. Saturday, a strong cold front will push through the coastal waters with strong offshore flow developing behind it Saturday evening through early Sunday. Small Craft Advisory conditions are expected from late Sat/early Sunday through Monday afternoon as the pressure gradient remains tight overhead. In addition, light to moderate rain will also be possible over the coastal waters throughout the weekend. Fire Weather Issued at 1124pm CST Wednesday Jan 21 2026 Light and variable winds, mainly out of the east, can be expected today and tomorrow, along with a warm and humid airmass. MinRH values range from the mid 60s to upper 80s today and tomorrow, while a nearby frontal boundary keeps isolated showers in the area. Saturday, moisture increases further ahead of a strong cold front that is now expected to sweep through the area throughout Saturday. This front will indwell bring much colder air but keep moisture in place through the end of the weekend, resulting in bitter cold and continued shower activity/humid conditions. Drier air finally begins to arrive late Sunday into Mon, with minRh values in the low 40s to low 50s early next week.
