(Tuesday through Wednesday) Issued at 243 AM CDT Tue Sep 17 2024 The remnants of Tropical Cyclone Francine will shift southward today near the Louisiana/Mississippi border. Additional rain chances will be possible across portions of the region, with the best chances across our South-Central Arkansas counties and all of our Louisiana parishes. However, models suggest Francine remnants will get absorb by this evening into a deepening trough across the Lower Mississippi Valley and SE CONUS, as a surface low moves into that region out of the Carolinas. With partly to mostly cloudy skies today, expect slightly below normal temps to remain, as highs are forecast to top out in the mid to upper 80s. By Tuesday evening, upper ridging will start to build into the region in wake of Francine remnants. Clouds should clear out, but overnight lows will once again fall into the upper 60s to lower 70s. Can`t rule out some patchy fog around daybreak Wednesday morning. Expect mostly sunny and warmer conditions to return to the region on Wednesday, with highs climbing into the low to mid 90s. && .LONG TERM... (Wednesday Night through Tuesday) Issued at 243 AM CDT Tue Sep 17 2024 Upper ridging is expected to remain in place through early next week. Expect quiet and mostly sunny conditions during this period, with highs in the low to mid 90s, and overnight lows remaining in the upper 60s to lower 70s. As we move into early next week, the ridge will flatten out, as an approaching longwave trough moves into the Southern Plains out of the Rockies. Long-range progs suggest the trough could make it into our extreme northern sections, just north of the Interstate 30 corridor. This would bring a return in rain chances across portions of Southeast Oklahoma and adjacent Southwest Arkansas by Tuesday. The remainder of the area should remain dry, as the ridge is expected to hold firm over the rest of the region. /20/ && .AVIATION...-- Changed Discussion --(12Z TAFS) Issued at 626 AM CDT Tue Sep 17 2024 Dealing with a mix of VFR/MVFR/IFR and LIFR ceilings attm across our airspace. For the most part, VSBY restrictions are confined to our NE TX terminals with FG still possible for the next couple hours at the TYR/GGG and LFK terminals. Look for these lower ceilings to eventually lift and/or scatter out by mid to late morning with VFR conditions returning to all terminals during the late morning and afternoon hours, albeit a little slower at the ELD and MLU terminals. Look for NE to E winds today generally under 10kts. 13-- End Changed Discussion --&& .PRELIMINARY POINT TEMPS/POPS...-- Changed Discussion --SHV 87 72 90 73 / 20 0 0 0 MLU 86 68 89 67 / 20 10 10 0 DEQ 86 66 89 66 / 20 0 0 0 TXK 87 69 90 70 / 20 0 0 0 ELD 85 65 88 65 / 20 10 0 0 TYR 89 71 93 73 / 0 0 0 0 GGG 88 70 91 72 / 10 0 0 0 LFK 90 72 92 72 / 10 0 10 0-- End Changed Discussion --&& .SHV WATCHES/WARNINGS/ADVISORIES...
