.DISCUSSION... Issued at 208 AM CDT Wed Oct 15 2025
WEDNESDAY (TODAY) AND THURSDAY:
A robust, upper lvl ridge will be settled across the Mid-South region of the CONUS extending eastward over the Southeastern region of the CONUS which will assist in the promotion of mostly sunny skies and fair weather across the Natural State. Additionally, regional sfc high pressure will lead to a continued advection of southerly to southeasterly flow into Arkansas ushering a warm and moist airmass across the state. Expect temperatures overall to remain unseasonably warm for this time of the year averaging about 5 to 10 degrees above normal overall.
FRIDAY THROUGH SUNDAY:
A significant pattern shift in the upper lvls is forecast to take place by late workweek (Friday). An upper lvl trof is projected to dig over the Central Plains region of the CONUS and will drive a cold front across Arkansas through the weekend. Latest model guidance of both the GFS and ECMWF continue to be in cohesion with regard to the occurrence of rain and thunderstorm activity ahead of and along the placement of the cold front; however, both are not in agreement on timing of this occurrence. The latest run as of this forecast discussion paints two different pictures:
1.) The GFS and related ensembles hint at a faster frontal passage with the leading edge of the rain and thunderstorm activity arriving into western Arkansas on Saturday morning. The earlier timing is more representative of a rain-event with limited potential for embedded strong to a few severe thunderstorms. A morning arrival of rain and thunderstorms could also limit the destabilization of the atmosphere which would potentially limit the high-end severe threat to a degree.
2.) The ECMWF presents a slower and potentially more potent solution. The model solution delays the arrival of the main line of strong to severe thunderstorms to until Saturday evening and into the overnight hours. The later timing would allow for greater diurnal heating and destabilization of the airmass ahead of the front potentially leading to a higher-end severe weather threat with a greater threat of significant, severe thunderstorms.
Over the next couple of days these models and shorter-term model guidance will continue to be closely analyzed to see which outcome appears more probable. However, the key takeaway should be that ingredients will be in place on Saturday into Saturday Night for severe weather across the Natural State and all hazards will be in play: damaging wind gusts, large hail, and a few tornadoes cannot be ruled out.
Into the day on Sunday, expect precipitation to come to an end across the eastern portion of the state. A much cooler and drier (via both the rain-cooled environment and the cooler and drier airmass behind the cold front) will lower temperatures to near or slightly below average temperatures for mid-October transitioning into later October.
MONDAY AND TUESDAY:
Into Monday, the cold front will push well east of Arkansas and sfc high pressure will occupy the region. In response this will usher in a cooler and drier airmass which will place temperatures overall near normal for mid-October transitioning into late-October.
At the end of the forecast period on Tuesday a warm front is progged to lift northward across the Natural State and will be the chance of a second bout of rainfall, but this rain opportunity does not appear to have severe weather potential attached to it.
