.DISCUSSION... (This afternoon through next Thursday) Issued at 1125 AM CDT Fri Sep 26 2025
All is clear and calm across the Mid-South in the wake of high pressure behind a cold front. With relatively strong CAA in place, today looks like the coolest day of the forecast period until at least the end of next week. Highs will be seasonably comfortable for early fall around 80 degrees with low humidity and plenty of sunshine. The upper level pattern will begin to modulate into an Omega Block over the central CONUS this weekend, ushering in a gradual warming trend. By Monday, an amplified ridge will be in place over the Mid-South. This will bring our temperatures above normal into the upper 80s to begin the work week.
Moving into the work week, the ridge looks to remain firmly in place through at least Wednesday, thus keeping temperatures above normal. On the bright side, dewpoints and resultant humidity look low enough that the temperature and heat index shouldn`t be off by more than a degree or two each day through midweek. There is some medium range uncertainty given the track of what is currently Invest AL94 in the Atlantic. If this storm favors the solution most heavily weighted by the ENS (ECMWF ensemble), remnants of this tropical depression may be steered westward enough to add some sporadic showers to an otherwise dry forecast on Wednesday and Thursday. Regardless, by Thursday night, the upper level pattern begins to deamplify and become more zonal. This will allow textbook climatologically cool and dry October air to filter in. As such, temperatures will cool down and PoPs will remain dry (
