| Area Forecast Discussion National Weather Service Lake Charles LA 1140pm CDT Tuesday Mar 28 2023 .SHORT TERM... (Tonight through Thursday night) Wx map shows cold front well south of the 60 nm marine zone boundary across the Northern Gulf, with northerly winds around 15 mph inland and around 20 knots offshore. The lingering light rain over the far southeastern marine zone south of the Atchafalaya River is rapidly dissipating. Satellite imagery showing continued clearing of the low to mid level cloudiness, with only scattered to broken cirrus streaming over the region. Temperatures in the mid to upper 70s across the area this afternoon. For tonight, the north to northeasterly winds expected to continue around 10-15 mph. Guidance shows at least the mid layer cloud cover returning. With the cooling mainly cold air advection, shouldn't be a big limiting factor tonight, expecting lows near 50/lower 50s north to the mid 50s along and south of the I-10 corridor Wednesday morning. For Wednesday a weak perturbation within the zonal flow aloft may generate a slight chance of showers across the far offshore coastal waters with the continued cloud cover. By afternoon, significant clearing expected across the inland areas with highs near 70. By Wednesday night to Thursday morning, a more easterly flow expected as the surface high moves northeast of the region. Winds likely to become nearly calm after sunset, coupled with the nearly clear skies, and allow temperatures to fall to the upper 40s/near 50 over Central Louisiana. Across Southeast Texas and Southwest Louisiana, overnight lows possibly limited with east to southeast winds and the return of lower cloud cover with lows in the upper 50s to lower 60s south of I-10. By Thursday, the upper level pattern will become more dominated by a digging longwave trough, with the ridge over the Gulf nudging further northward. Mostly cloudy skies expected to nudge further northeast across the area. Afternoon highs in the upper 70s to near 80 expected. Southeast winds expected to slowly increase Thursday evening and overnight, keeping temperatures in the mid 60s to near 70 for overnight lows. Long Term (Friday through next Monday) Early Friday we begin the period with a cold front draped from the Great Lakes to South TX, with low pressure over Kansas and high pressure off the coast of the Carolinas. Between these two features a tightening pressure gradient overhead will allow southerly winds to become strong and gusty, with frequent gusts to 30-40 kts expected through Fri afternoon. As a result, a warm and humid end to the work week is in store, with highs topping out in the low to mid 80s. By Fri afternoon/evening, a few showers will become possible across our northern zones closer to the approaching cold front, while elsewhere most cloudy skies can be expected. Heading into the weekend, the cold front is expected to make its way through the CWA (County Warning Area) early Sat, before eventually stalling in the coastal waters shortly thereafter. However, models continue to diverge on the placement/progression of this front through the weekend. The most likely scenario at this point seems to be frontal passage early Sat, the front meandering offshore or near the coast late Sat/early Sun, followed by the boundary lifting north through the region late Sun/early Mon. With the boundary to our south, some drier air should make its way into the region for the start of the weekend however, highs will continue to warm into the low to mid 80s both Sat and Sunday as cooler air will be lacking. As the boundary lifts back through the region towards the end of the weekend, warm/moist air returns along with at least some isolated to scattered showers. Monday and Tues will then consist of very warm and humid weather, with highs in the mid to upper 80s (potentially approaching 90 in a few spots) and overnight lows in the mid 60s to low 70s. 17 NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None.
