| Area Forecast Discussion National Weather Service Lake Charles LA 220am CDT Fri Mar 13 2026 ...New SHORT TERM, LONG TERM, Marine IRE WEATHER... .KEY MESSAGES... - Winds turn onshore today, bringing warmth and humidity back to the forecast before the next cold frontal passage Sunday night. - Showers and storms possible Sunday night with the frontal passage. There is a Marginal to Slight Risk of damaging winds to come with stronger segments of the line. - Light freeze possible for interior TX and cenLA Tuesdayam as temps fall into the low 30s. .SHORT TERM... (Today through Sunday night) Issued at 211am CDT Fri Mar 13 2026 Surface analysis shows high pressure draped from south TX to the Carolinas tonight, providing light winds and clear skies across the forecast area. High pressure will slide east today, while the flow aloft becomes zonal overhead, bringing about a warming/moistening trend that will prevail through the remainder of the short term. Today, pleasant and seasonal weather is on tap as highs warm into the low to mid 70s amid sunny skies. Moisture return becomes more apparent as we head into the weekend, as dewpoints creep back into the upper 50s to near 60 degrees tomorrow, allowing highs to reach into the mid to upper 70s. Still, a pleasant and dry Saturday afternoon is on tap with no concerns for any planned outdoor activities. Late tomorrow into Sunday, the next potent storm system takes shape across the center of the country as a deepening mid/upper level trough dives out of the northern Rockies and across the Plains, while at the surface, strong low pressure and an associated frontal system take a similar path. The pressure gradient overhead will quickly tighten throughout Sunday as this frontal system dives south and east across the center of the country, allowing onshore flow to pump even more moisture inland overhead. The boundary eventually sweeps through the forecast area Sunday night, with showers and storms accompanying it, some of which may be severe. The front will sweep through quickly, with convection coming to an end by sunrise Monday. Long Term (Monday through Friday) Issued at 211am CDT Fri Mar 13 2026 Strong offshore flow will usher in a much colder and drier airmass on Monday in the wake of Sunday night's frontal passage. Dewpoints fall into the teens by Monday afternoon, which in combinations with gusty north winds will likely lead to some fire danger concerns. In addition, temperatures will struggle to warm, only making it into the mid to upper 50s Monday afternoon. Monday night will bring the coldest temps of the forecast period, and possible our last real taste of real cold this season, with temperatures dipping into the 30s area-wide and likely below freezing across CENLA. Post-frontal surface high settles overhead on Tuesday before shifting off to the east Wednesday, bringing about another warming/moistening trend through the mid-week. No rainfall is expected through the remainder of the forecast period, but dewpoints will slow rebound back into the upper 50s/low 60s by late Thurs/early Fri. Temperatures remain below normal on Tuesday, near seasonal norms on Wednesday, and then back to above normal thereafter. Marine Issued at 211am CDT Fri Mar 13 2026 Surface high pressure overhead tonight has allowed winds to become very light and seas to relax. High pressure will slide east later today, allowing winds to turn southerly once again. Light to moderate southerly flow will continue until the passage of another cold front Sunday evening that will bring showers and storms followed by another round of Gale force winds in its wake. Fire Weather Issued at 211am CDT Fri Mar 13 2026 Light onshore flow returns today, as surface high pressure exits off to the east. Onshore flow continues through the weekend, allowing moisture to slowly pool overhead ahead of another cold front that will sweep through Sunday night. This front will bring another round of showers and storms followed by a period of strong offshore flow and very dry conditions that will likely lead to elevated fire weather concerns on Monday NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None. GM...None. |
