203 FXUS64 KLZK 181642 AFDLZK Area Forecast Discussion National Weather Service Little Rock AR 1142 AM CDT Mon Aug 18 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1225 AM CDT Mon Aug 18 2025 -Dangerous heat will persist across the state for another couple days before some relief is seen. -Isolated showers/storms are possible again today, with microbursts possibly producing strong wind gusts in a few storms. -Rainfall may be a little more widespread Tue-Wed as a cold front moves across the state. && .DISCUSSION... Issued at 1225 AM CDT Mon Aug 18 2025 Another day of dangerous heat is expected across the state and heat headlines have been expanded to include extreme heat warnings for portions of eastern, central and western Arkansas. High temperatures on Sunday were fairly extreme in nature, with KRUE hitting 106 F for an afternoon high. Many other reporting stations hit the century mark as well. These numbers were close to yesterday`s NBM90 values and utilized some of that data to forecast today`s high temperatures. Isolated showers/storms possible once again today, mainly during the afternoon/evening hours. Main concerns will again be microbursts that could produce very localized wind damage, as well as a few heavy downpours. H500 ridging will begin to expand west across the western CONUS over the next few days which will provide mid-level NW/N flow across the region. This will help push a cold front through and as the front moves across the area, precip may become a bit more widespread. Will have to watch for isolated severe storms given the heat and associated extreme instability in place near the boundary. Some areas could begin to see relief on Tuesday with more of the state expected to see cooler temps by Wed-Thu. Will monitor latest trends to see if/where heat headlines are needed over the next couple days. Will continue to see temperatures closer to normal through the upcoming weekend with a break in heat headlines possible for several days. Another front may move across the state by early next week which could provide below normal temperatures for late August across Arkansas. && .AVIATION... (18Z TAFS) Issued at 1142 AM CDT Mon Aug 18 2025 Expect VFR flight category across all sites for the duration of the forecast period from Monday afternoon through Tuesday afternoon. Introduced TEMPO groups for Monday afternoon into Monday evening for TSRA which will have a microburst potential. It is advised not to fly into any thunderstorm cells today as microburst potential is extremely high looking at all parameters. The sudden rush of air downward (downburst or microburst potential) will exist at the surface and at flight level within storms that do develop. Storms will wane into later Monday evening at to after sunset. Conditions will become fair and clear across the forecast area into by Monday night into early Tuesday morning. && .PRELIMINARY POINT TEMPS/POPS...
