926 FXUS64 KLZK 220614 AAA AFDLZK Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 114 AM CDT Sun Sep 22 2024 ...New AVIATION... .SHORT TERM... (This evening through Monday) Issued at 144 PM CDT Sat Sep 21 2024 Rain showers and isolated thunderstorms will continue across northern and northeast Arkansas through late this evening, as a short-wave trough moves across the southern Midwest region and northern Arkansas. The main threats with this activity will be heavy rain with potential for localized flooding. The aforementioned short-wave trough is moving along anticyclonic flow associated with a widespread High situated across much of the southern and southeastern CONUS. With the exception of north/northeast AR, the rest of the state is experiencing mainly hot and dry conditions through much of the weekend, with high temperatures in the 90s expected. A heat advisory is in effect across much of central to western portions of the CWA through Saturday evening, with heat index values between 105-110F forecast. Showers and potential for storms will return by Sunday afternoon, across northern portions of the state, spreading across much of the rest of Arkansas by Monday midday, as a cold front pushes eastward across the region. Widespread cloud cover and rainfall will keep temperatures on the lower end across western and northern Arkansas Monday, in the lower 70s to mid 80s. At this time, it looks like central, southern and eastern Arkansas will have time to warm up to the 90s Monday, before cloud cover and rain spread into these areas. We can all look forward to much cooler air in the long term period next week. && .LONG TERM... (Monday Night through next Saturday) Issued at 144 PM CDT Sat Sep 21 2024 Significant changes are expected across the state at the start of the period. H500 trough across the Central Plains will continue its way toward the Great Lakes which will compress the srn H500 ridge southward. At the sfc, a cold front will be making its way across the state. This front will usher in cooler temperatures. Through the middle to later part of next week, a second mid-level trough looks to dive S-SE from the Northern Plains toward the Mid-MS Valley. As this occurs it may intensify and become cutoff somewhere in the vicinity of the state as H500 ridges flank it to the east and west. At the sfc, ridging will settle in from the Great Lakes S-SW toward the state. This will lead to a period of fairly cool temperatures and some occasional rain chances/periodic cloud cover. && .AVIATION... (06Z TAFS) Issued at 112 AM CDT Sun Sep 22 2024 Some additional convection looks to redevelop for Sun late morning into the afternoon hrs...mainly across NRN AR. Chances will then drop SE Sun night into Mon near the end of this TAF PD. Winds should remain less than 10 kts sustained, w/ VFR condns prevailing otherwise thru the day Sun. && .PRELIMINARY POINT TEMPS/POPS...
