Area Forecast Discussion National Weather Service Little Rock AR 644 AM CDT Mon Sep 22 2025 ...New AVIATION... .KEY MESSAGES... Issued at 145 AM CDT Mon Sep 22 2025 -Strong to severe storms with multiple rounds posing a flash flood threat will be possible across central to northern Arkansas overnight through Monday morning. -Areas of rainy conditions continuing through mid-week, with more widespread rains Tuesday into Wednesday. -Cooling temperatures to at or below normal levels going into late this week. && .DISCUSSION... Issued at 145 AM CDT Mon Sep 22 2025 Training showers and storms across portions of western Arkansas (currently the Crawford, Sebastian, Franklin, Logan and Johnson County area) will pose a flash flood threat as cells continue to form along a boundary that is in a favorable area for development due to a strengthening LLJ across eastern Oklahoma and western Arkansas. Stronger storms will additionally pose a strong to severe wind and small hail threat. CAM's continue to struggle with storm evolution/maintenance going into the morning hours, but general thinking is showers and storms will continue to push eastward across Arkansas through daybreak. At that point, more uncertainty in storm evolution exists heading into the afternoon hours, where CAM's generally show a downward trend in activity, but cannot rule out activity extending into portions of central to southern Arkansas later today. Temperatures are expected to generally cool back towards normal levels (low to mid-80s for central Arkansas) through early week. Heading into the middle of the week, a mid-level disturbance moving across the Central Plains will aid in strengthening low pressure across that general region, with a cold front moving across Arkansas Tuesday into Wednesday. This will bring the next round of widespread rains to the region and, depending on timing, could result in the opportunity for strong to severe storms along and ahead of the front. Post front, much cooler temperatures are expected to settle into the region, where highs in the 70s and 80s will continue through the end of the week. Quieter weather is anticipated going through this weekend and into next week as high pressure builds across the region, resulting in slight warming temperatures back towards normal levels. && .AVIATION... (12Z TAFS) Issued at 645 AM CDT Mon Sep 22 2025 Periods of shower and storm activity throughout the forecast period will be the main aviation challenge. Most activity is currently remaining outside of the terminal reach, but general southerly movement of showers and storms should result in VCSH becoming -RA/-TSRA for periods this morning and into the afternoon. Convection is generally expected to dissipate going into the evening hours, resulting in improving ceilings/visibilities during this period. Some lingering showery activity across northern Arkansas may keep some lowered ceilings for the northern terminals, with an MCS possibly impinging on northwestern Arkansas towards the end of the period. Areas that remain mostly clear and receive some precipitation may see some IFR/LIFR ceilings in visibilities during the overnight hours tonight. && .PRELIMINARY POINT TEMPS/POPS...
