.DISCUSSION... (Tonight through next Tuesday) Issued at 1130 PM CDT Tue Sep 9 2025
The upper pattern currently remains benign over the southeastern CONUS with weak high pressure to our east and daily, weak lee cyclogenesis throughout the High Plains. This places the Mid- South in a pattern consisting of moderate (55-60 F) dewpoints and higher temperatures. The pattern is expected to amplify with a large ridge developing over the Plains through the week, with the ridge gradually translating into the region by this weekend. In response, surface temperatures are expected to climb into the mid to upper 90s by the end of the week. Low surface humidity will keep heat indices under triple digits.
PoPs will also remain almost non-existent through this weekend, and likely into next week as well. Looking at today`s upper soundings, both observed and forecast, decent riding is evident from around 700 mb and up. With nebulous forcing from weak troughing over the eastern CONUS and low dew points, instability will remain limited enough to prevent meaningful precipitation. Furthermore, as the amplified ridge from the west makes its way east, upper ridging will further cap off any attempts at deep convection. Guidance is keen on keeping this ridge over the region through at least the middle of next week before ensembles begin to diverge, but still average out to a weak pattern. Lastly, much of the region is in a D1 (moderate) drought with localized areas of D2 (severe) drought. With no rain in the forecast for at least the next week and no current threat of landfalling tropical systems, drought conditions will worsen with time throughout the entirety of the Mid-South throughout the forecast period.
Temperatures are also likely (60%-80% per latest NBM) to remain in the mid to upper 90s through next week as the amplified Plains ridge settles over the region. Once again, heat indices will be tempered by low humidity, unlikely to rise more than a couple degrees above the air temperatures. However, heat may still be uncomfortable as we experience summer- like air for an extended period of time, but some relief will be experienced overnight with lows in the 60s and low 70s.

.FIRE WEATHER... Issued at 1130 PM CDT Tue Sep 9 2025
Expect elevated fire danger through the period. Minimum relative humidity values are already bordering on 30% - 40% as of today and are expected to continue falling through the next five days. By Saturday, minimum relative humidity values will drop below 30% nearly area-wide, lasting into next week. Additionally, the majority of the region is in at least a D1 (moderate) drought which will continue to worsen with time due to a lack of precipitation in the forecast. However, light 20-foot winds will keep more serious fire concerns at bay for the time-being.
