Synopsis.. A more prevalent onshore flow is expected to develop as the remnants of nicholas continue to weaken and lift out to the north. This onshore flow is forecast to remain generally light through the weekend, but will become more modest early next week as the pressure gradient tightens across the area ahead of an approaching cold front.

Area Forecast Discussion National Weather Service Lake Charles LA 633 AM CDT Fri Sep 17 2021

DISCUSSION. For the 09/17/21 1200 UTC TAF package.

AVIATION. IFR to MVFR conditions are expected to linger KAEX-KBPT-KLCH through the morning, improving to VFR early afternoon at the latter two as low clouds gradually lift and erode. For AEX, MVFR will improve to VFR mid to late afternoon, though convective coverage will also be on the increase during this time period, with the best chances of a TSTM affecting the terminal from late afternoon into early evening. VFR is expected to generally prevail away from afternoon convection at the Acadiana terminals, once some early morning VSBY restrictions at KARA improve in a couple of hours.

PREV DISCUSSION. /issued 405 AM CDT Fri Sep 17 2021/

SHORT TERM [Today through Sunday] .

The broad/weak remnant SFC low of Nicholas appears to be located across west central LA early this morning based on SFC Obs and data from KPOE, with a small cluster of showers noted near the presumed center, and other isolated showers over the SE TX/SW LA coastal waters. A combination of very low stratus along with considerable cirrus streaming overhead from the SW will yield yet another cloud filled morning across the area, though at least some locations will see a few peeks of sun.

While the SFC reflection of Nicholas is expected to continue to degrade into an open trof while lifting off to the north, a shortwave trof/upper low noted in water vapor satellite imagery over the TX/OK border is progged to continue sinking TWD the SE, and will become entangled with the lingering circulation of Nicholas aloft, maintaining a trof axis near the Sabine River through the duration of the short range period, though it will begin to weaken/open up and start slowly lifting out on SUN.

A wedge of relatively drier air nosing in from the SW will be present today, resulting in lower PoPs across SE TX and parts of SW LA, however deeper MSTR is progged to wrap around the WRN flank of the digging shortwave trof resulting in more equitable areawide distribution SAT and SUN. Temperatures will continue to be moderated by cloud cover and rainfall, but should be warmer today than they have been the past few with more breaks in the clouds and precipitation that is not as widespread.

13

LONG TERM [Monday through Thursday] .

From Monday into Tuesday, the persistent upper trough over the region will be weakening and gradually lifting north as a stronger northern stream trough digs acrs the cntl Rockies. This system will usher a sfc front southeastward toward the southern plains and lower MS Valley as it progresses east through midweek. Moisture levels acrs the area will remain abv normal, with precip water values running between 1.7 and 2.0 inches on Monday and Tuesday. The lingering weakness aloft on Monday and the approaching front on Tuesday will keep elevated rain chcs acrs the area early next week. Sounding profiles suggest enough instability for thunderstorms acrs the area, but upper support will be minimal as the energy associated with the larger trough will translate east acrs the upper Midwest and Great Lakes Region.

Guidance is in fairly good agreement regarding the timing of the front, with a slow FROPA acrs the area Tuesday night into Wednesday. Rain chcs will continue on Wednesday, but should taper off from N to S as drier air in the wake of the front begins to spill southward. The latter part of the week continues to look like a nice change of pace from the recent wet weather pattern, with high pres building into the area.

Temperatures from Monday through Tuesday night are expected to run near or a little abv normal, with lows in the lower 70s Monday night and the upper 60s to lower 70s Tuesday night, and highs in the upper 80s both days. With the passage of the front late Tuesday into early Wednesday, high pres will bring a cooler airmass into the region, and this should help moderate daytime temperatures with highs possibly just reaching the lower 80s by Thursday while overnight lows could fall into the upper 50s north to lower 60s south.

MARINE . A more prevalent onshore flow is expected to develop as the remnants of Nicholas continue to weaken and lift out to the north. This onshore flow is forecast to remain generally light through the weekend, but will become more modest early next week as the pressure gradient tightens across the area ahead of an approaching cold front.
