603 FXUS64 KLZK 171938 AFDLZK Area Forecast Discussion National Weather Service Little Rock AR 238 PM CDT Sat Aug 17 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Monday) Issued at 237 PM CDT Sat Aug 17 2024 Latest satellite and surface observations indicate clear conditions across the northern half of the forecast area, with scattered to broken mid level clouds across the southern half. Previous convection/MCS activity has overturned the atmospheric column, most noticeably across western sections. Sunday should be the last day of the current heat headline streak, as a cold front will move south and approach the state on Sunday. The feature will be associated with an amplifying flow pattern across the U.S., allowing for a more developed northwest flow across the mid south. Mid level disturbances in this flow should be able to promote at least one thunderstorm complex late Sunday and Monday, which would then move south into the forecast area. The air mass change associated with the front will be noticeable; point forecasts at observing sites indicate below normal temperatures at a number of locations. && .LONG TERM... (Monday Night through next Saturday) Issued at 237 PM CDT Sat Aug 17 2024 To begin the period, high pressure will begin to take control of the weather pattern...although with cooler and drier air over the state. The high pressure system that brought dangerously hot conditions over the state the previous week will begin to retreat towards the west as clockwise flow around the high pressure gives way to northerly flow aloft. This will result in lower humidity values across the region. As mentioned above, "cooler" temperatures are expected to move into the state. With that said, it will still be on the warm side with forecast high temperatures in the 80s to lower 90s. Low temperatures are expected to drop into the upper 50s to upper 60s. && .AVIATION... (18Z TAFS) Issued at 1213 PM CDT Sat Aug 17 2024 Remaining showers across southeast sections will end by 1930z. Expect areas of MVFR visibility due to fog late tonight across western sections of the forecast area. && .PRELIMINARY POINT TEMPS/POPS...
