| Area Forecast Discussion National Weather Service Lake Charles LA 537am CST Tuesday Jan 20 2026 .SHORT TERM... (Today through Thursday night) Issued at 1204am CST Tuesday Jan 20 2026 A longwave trough centered over the Hudson Bay will help steer the active Jet across the Ohio Valley through the short term keeping cold air to the north. Locally, a surface high pressure cell located over the lower TN Valley will shift east toward the Eastern Seaboard. This pattern will allow a broad onshore regime to take place lifting daytime high temperatures above normal particularly for lower Southeast TX and Southwest LA. High temperatures will trend in the 60's this afternoon with dry weather. As moisture advection into the Southern Plains continues into Wednesday, a weak surface trough will deepen off southern TX while phasing with with downstream front extending SW from the Ohio Valley. Showers will increase in coverage throughout Wednesday yielding wide spread wetting rainfalls ranging from a 0.25 to 0.75 inches. Kowalski / 30 Long Term (Friday through Tuesday) Issued at 1204am CST Tuesday Jan 20 2026 By Thursday morning, lingering rainshowers will start to trail off to the north and east, however, weak advection behind the front has this feature stall to the north of the forecast area allowing the Gulf air to further influence temperatures Thursday toward 70 south of HWY 190, while CenLA trends in the mid 60's. Friday the pattern quickly begins to shift as the upper level Jet increased speed divergence aloft over the Western CONUS while the subtropical jet also begins to accelerate east of Baja. Positioning of these two local Jet Max, creates a strong high pressure cell over the upper Midwest as cold arctic air descends southeast. While showers are not expected to be widespread Friday, chances do increase overnight into Saturday with cold air moving toward the coast with the stationary boundary now shifting offshore. It's important to note there is still quite a bit of spread in the modeling regarding timing of colder air reaching the forecast area, but confidence has increase that temperatures will struggle in the 40's. Areas south of I-10 may approach 50°F briefly while highs across CenLA keep to the low 40's. Barring any major forecast shifts the primary precipitation Saturday will be a cold rain as temperatures remain above freezing during the daylight hours. After sunset, strong Cold Air Advection advection continues while light precipitation remains in the forecast. There will likely be a transition zone shifting south from the north portion of Louisiana southward during the evening and overnight hours to freezing rain and/or sleet. Wet surfaces generally take a little longer to cool due to latent heat. That said, the concern for wintry weather peaks early Sunday morning where freezing precipitation trends to the I-10 corridor. Model guidance still suggest temperatures warm above freezing areawide by midday thus eroding any light freezing rain accumulations, should there be any. Lingering precipitation may hold through the afternoon hours Sunday, which at this stage in the forecast range appears to be all rain including CenLA. Thus the main time of concern here will fall late Saturday night into the middle of Sunday morning where locations north of I-10 may have enough hours below freezing to accrue minor accumulations. Precipitation begins to slide out of the area by Sunday night while cold air continue to propagate into the forecast area. Widespread 20's and potentially upper teens are possible waking up early Monday morning. With north winds remaining in place, it is possible additional headlines for hazardously cold temperatures / wind chills may be needed Sunday night into Monday. Again, it is very important to stress that uncertainty still remains in the timing of cold air with the precipitation. For now, any impactful wintry weather that occurs, is currently favored toward CenLA per this current forecast cycle. Kowalski / 30 Marine Issued at 1204am CST Tuesday Jan 20 2026 Light easterly winds and low seas will prevail today with winds and seas increasing tonight into Wednesday ahead of a coastal low that will move up the Texas gulf coast bringing showers across the coastal waters Wednesday and Thursday. A strong cold front will push through the coastal waters Friday night with strong offshore flow developing behind it Saturday and Sunday. Light rain will also be possible over the coastal waters through the weekend. Fire Weather Issued at 1204am CST Tuesday Jan 20 2026 Minimum RH Values will range 35-45% this afternoon with light east winds. Later, winds will turn out of the southeast this evening increasing dewpoints and bringing minimum RH values up. A coastal low will move across the region Wednesday and Thursday accompanied by widespread light showers. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None.
