Area Forecast Discussion National Weather Service Lake Charles LA 1251 PM CDT Sun May 10 2026 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... - A few afternoon thunderstorms will develop in response to afternoon heating within a very tropical airmass. - Patchy fog will be possible again early Monday morning where winds calm, but may be disrupted by storms. - A cold front will move through the region Monday accompanied by showers and thunderstorms. - A dry and warming pattern develops from mid week onward. && .DISCUSSION... (This evening through next Saturday) Issued at 1246 PM CDT Sun May 10 2026 A few light showers have been ongoing near the coast and offshore this morning, but with no real upper level support, coverage has been much lower than has been seen in recent days. A few more, diurnally driven, thunderstorms are expected to develop this afternoon. The influence of an approaching upper trof will provide better upper level support overnight for the continuation of scattered showers and thunderstorms. Patchy fog will be possible once again early Monday morning where showers are not actively occurring and winds calm. Any fog that develops should either dissipate or lift into a low level stratus layer by 9 AM Monday morning. The fog and convection will precede a cold front that is now progged to push through the region during the day Monday rather than the early Monday morning timeframe being advertised at this time yesterday. This front will be noticeable, but the supplanting airmass won't be as cold or as dry as recent anomalously cool events. It is mid May after all. Still, temperatures and dewpoints will fall into the low to mid 60s Tuesday morning as high pressure settles briefly overhead. This high will slide east of the area by Wednesday turning winds back out of the south and initializing a warming pattern through the rest of the week. Afternoon highs will climb into the mid to upper 80s although dewpoints will remain relatively reasonable (for this part of the world) in the 60s. Jones && .AVIATION... (18Z TAFS) Issued at 1246 PM CDT Sun May 10 2026 Ceilings are currently fluctuating between MVFR and VFR, but should continue to improve to VFR through the afternoon. A few showers and thunderstorms may develop this afternoon, but probabilities are low. Precipitation chances will increase overnight into Monday with the approach of a cold front. Ceilings will fall to MVFR and possibly IFR after 08Z. Patchy fog will be possible where winds calm and precipitation doesn't disrupt development. Any fog that develops will dissipate by 14Z. A cold front will push through the region near the end of the taf period turning light winds out of the north. Jones && .MARINE... Issued at 1246 PM CDT Sun May 10 2026 A few, light showers will continue over the coastal waters through Monday afternoon along with light onshore winds. A cold front will push through the coastal waters Monday afternoon bringing the precipitation to an end and turning winds offshore between 10-15 knots. High pressure slides east of the region Wednesday turning winds back onshore through the end of the week. && .FIRE WEATHER... Issued at 1246 PM CDT Sun May 10 2026 A few showers and thunderstorms will develop this afternoon and continue overnight ahead of a cold front that will push through the area Monday. Precipitation will come to an end behind the front with light northerly winds developing in its wake that will advect some cooler, drier air into the region Monday night into Tuesday. Minimum RH values Wednesday will fall into the 40-50% range. Outside of precipitation tonight and Monday, conditions will be generally favorable for prescribed burning although portions of the region remain in a drought. && .LCH WATCHES/WARNINGS/ADVISORIES...
