.DISCUSSION... (This afternoon through next Thursday) Issued at 1100 AM CDT Fri Oct 3 2025
High pressure has shifted east of the Mid-South and we now reside on the backside of the system. This results in cooler conditions than the last few days as temperatures range from 1-5 degrees cooler than 24 hours ago. High temperatures will still reside in the 80s, which is above normal for early October. While temperatures remain above normal, dewpoints have been mild in the 50s and 60s to keep humidity levels at bay.
An upper level low still looks to develop along the Gulf Coast. Guidance shows this system developing rather quickly and not allowing much time over the warm waters. This will likely refrain the system reaching tropical cyclone status, but it will feed plentiful moisture to the Mid-South. The advancement of moisture will increase rain chances early next week. Guidance is in agreement with development of the system, but still lacks agreement of rainfall onset. Nonetheless, the moisture advection will soar PW values well above climatology for this time of year, in the 90th percentile. NBM QPF values appear to be underdone, but this could be due to the aforementioned timing differences.
Another chance at widespread rainfall and cooler, more seasonable temperatures will arrive late next week.. A weak cold front will take aim from its parent low on track across the Northern Plains. With still being nearly a week away, there is model disagreement in the precise timing and magnitude of the cooling, but temperatures are favored to be closer to climatology.

Light 20ft winds combined with elevated forecast fuel moisture keeps fire weather concerns low.
