826 FXUS64 KSHV 272326 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 626 PM CDT Sat Apr 27 2024 ...New AVIATION... .SHORT TERM... (This evening through Sunday Night) Issued at 225 PM CDT Sat Apr 27 2024 Very active weather should return to the region tonight, as a very robust line of thunderstorms begins to work into our western zones towards Sunday morning. This line will pose both a heavy rain threat, and a severe weather threat for our entire area through Monday evening. Given rainfall amounts the other day, and QPF amounts expected into the new workweek, a flood watch will go into effect Sunday morning, and remain in effect through the main heavy rain window, with 2-4 inches of rain, and locally heavier amounts possible. Regarding the severe weather threat tomorrow, this is where it gets...somewhat complicated. I hesitate to say the severe weather threat is secondary compared to the flooding threat, because that is certainly not the case, but the severe weather threat is very conditional. On the flip side of that, the environment overhead is very supportive of a severe weather threat, and I could very much see portions of our region being upgraded into an Enhanced Risk come tomorrow morning. It all boils down to forcing along the boundary, and the scope of convection across the region through tomorrow. Severe storms tomorrow would be capable of all modes of severe weather, including embedded tornadoes along the main line. This line of storms should exit the region by Monday evening, with the flood watch expiring shortly behind it. However, look for a disturbed pattern to continue into the long-term. /44/ && .LONG TERM... (Monday through next Friday) Issued at 225 PM CDT Sat Apr 27 2024 Disturbed pattern should remain across the region, as SW flow quickly returns behind this trough. Rain should remain in the forecast, before better rain chances return towards the weekend with a small shortwave approaching the region. Additional moderate to heavy rainfall may be possible with this system, but it appears very progressive in nature. Regardless, look for additional adjustments and updates to the forecast over the coming week. /44/ && .AVIATION... (00Z TAFS) Issued at 622 PM CDT Sat Apr 27 2024 Very strong pressure gradient remains in place across our airspace with sustained SSE winds near 12-18kts with gusts upwards of 30kts. These winds will likely continue overnight, especially across our western most terminal locations. VFR conditions currently prevailing but that will be changing as we move into the late evening and overnight hours with MVFR conditions returning. Should see ceiling recovery to most terminal locations after sunrise Sunday Morning. Decaying broken line of thunderstorms will be moving into our far northwest airspace by 12z Sun with the possibility of VCTS impacting the TXK/TYR/GGG terminals by mid morning. Convection much more likely late in the TAF period at the above mentioned terminals so kept VCTS going at those locations along with the LFK terminal. Other terminal impacts from TSRA appears to occur just beyond this 00z TAF package. 13 && .PRELIMINARY POINT TEMPS/POPS...
