938 FXUS64 KLZK 250524 AFDLZK Area Forecast Discussion National Weather Service Little Rock AR 1224 AM CDT Sat May 25 2024 ...New AVIATION... .SHORT TERM... (This evening through Sunday) Issued at 238 PM CDT Fri May 24 2024 We were not able to complete a 12Z radiosonde launch today due to lightning at the station, so an 18Z flight had to suffice. Sounding revealed no surprises, with about 3200 j/kg CAPE in place, along with a cap. Several clusters of thunderstorms have been trying to develop this afternoon in the western portions of the forecast area. Storms have managed to develop quickly and appeared to approach severe limits at times, but with a lack of shear the convective cells were not able to intensify and sustain themselves despite the significant elevated instability in place. For the third night in a row, additional convective development is expected. Further bolstering convection tonight will be a weak front dropping down into NW Arkansas, which should make it`s way into central AR by morning. The front should retreat back to the north during the day, and should result in drier weather during the daytime hours tomorrow...at least for most areas. I am anticipating another round of nocturnal storms Saturday night...although these will probably remain primarily across the northern portions of the forecast area. Sunday looks to be dry across most of the area, with the exception of the northeast where additional showers and thunderstorms are possible. && .LONG TERM... (Sunday Night through next Friday) Issued at 238 PM CDT Fri May 24 2024 An upper ridge will be over the Gulf of Mexico to begin the long term period with southwest flow over Arkansas and an upper low over the northern U.S. The upper low will move across the Great Lakes and Midwest Monday. Another upper low moves through the Great Lakes Tuesday as the flow aloft over Arkansas becomes northwest. An upper ridge develops over the Rockies Wednesday and moves into the Plains Thursday and Friday. A cold front will be northwest of Arkansas Sunday night, and will move through the state early Monday with showers and thunderstorms. Will keep a slight chance of showers and thunderstorms in for Monday evening should there be some left over instability. Weak high pressure builds into the area Tuesday through Thursday. A slight chance of showers and thunderstorms are expected during the day Wednesday and Thursday as short waves move through the state. A warm front approaches from the south Friday and with moisture returning, a chance of showers and thunderstorms has been included. Near to above normal temperatures are expected through the period. && .AVIATION... (06Z TAFS) Issued at 1220 AM CDT Sat May 25 2024 SHRA/TSRA will continue through part of the overnight hours across most terminals. TEMPO groups and VCTS have been written into TAFs to account for uncertainty in coverage. Shower and thunderstorm activity should shift east of the area just before daybreak. Patchy fog will be possible for terminals that clear out and where wind calm. Mostly MVFR/IFR conditions are expected through the period with IFR conditions possible for terminals that see heavy rain from thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
