669 FXUS64 KLZK 132307 AFDLZK Area Forecast Discussion National Weather Service Little Rock AR 607 PM CDT Tue Aug 13 2024 ...New AVIATION... .SHORT TERM... (This evening through Thursday) Issued at 218 PM CDT Tue Aug 13 2024 Latest observations indicate the remaining cells that combined to form a linear MCS are now moving into northeast portions of the forecast area. This activity will move east of the CWA by 2130z. CAM guidance suggests a similar MCS type event will form overnight, but will start slightly east of where the activity of last night formed. Northeast sections of the forecast area will have the highest probability of experiencing this convection. Conditions promoting high heat stress will continue through this period. Appropriate headlines are in effect. Additional headlines may be required for Thursday. && .LONG TERM... (Thursday Night through next Tuesday) Issued at 218 PM CDT Tue Aug 13 2024 H500 ridging is expected to dominate the pattern through much of the long term portion of the forecast, as it should extend from the SW US eastward toward the Gulf Coast. With sfc ridging expected across the SE through much of the period, S-SW low level flow will keep a steady stream of moist air in place across the state. This combination will lead to a period of above normal temperatures as well as dangerous heat indices. Heat headlines are likely nearly every day for at least some parts of the state. While the forecast looks largely dry in nature, a slow moving mid- level low will work its way around the periphery of the ridge toward the eastern US. As ridging across the SW builds north, this will provide a persistent H500 NW flow setup across the middle of the country. Arkansas will be on the edge of this setup which will lead to occasional chances for showers and storms, especially across northern and eastern parts of the state where remnant MCSs could pass through the mean flow. && .AVIATION... (00Z TAFS) Issued at 606 PM CDT Tue Aug 13 2024 Expect VFR flight category between Tuesday evening and Wednesday evening at all terminals with exception to the northern sites of KHRO and KBPK which will see lowering CIGS to IFR flight category early Wednesday morning. Additionally, showers and thunderstorms via another complex exiting Missouri will likely impact the terminals of KHRO and KBPK, with the possibility of some shower and thunderstorm activity making it into the central site of KLIT around sunrise on Wednesday. && .PRELIMINARY POINT TEMPS/POPS...
