.DISCUSSION... Issued at 1214 PM CDT Wed Oct 15 2025
Through Friday: An unusually strong subtropical ridge remains fixed over the Southern Plains to Lower MS Valley region. This will continue a long stretch of above normal temperatures and dry conditions, and it`s not out of the question for a few locations to reach 90 deg F in the next few days. Overnight lows moderate through the week in response to low level moisture increases preceding the weekend front. Lows tonight will drop into the upper 50s F but will only dip into the lower/mid 60s F through the remainder of the week. /EC/86/
Saturday into Next Week: Global models continue to indicate a window of opportunity from late Saturday afternoon into at least the first half of Saturday night, where some potential for severe storms will exist across mainly the Delta region. This specific area is currently where the better conglomeration of wind shear, instability, and forcing is forecast to reside as a cold front moves into the forecast area. Damaging wind gusts to 60 mph will be the primary concern with such storms. There still remains some uncertainty in the exact evolution of this system and timing, in addition to the track of some key features, and whether or not there will be enough adequate level of instability in place ahead of the front. Therefore, please continue to monitor the latest forecast for the most up-to-date information concerning this severe potential this weekend. For now we continue to advertise a marginal/slight risk over northwest/northern portions of the area.
Rainfall totals across the forecast area during this time look to generally hover between 0.50-1.50 inches, with locally higher amounts possible. The higher QPF amounts continue to exist across the northern half of the CWA. This would be some much welcomed and needed rainfall for the area, but it won`t put much of a dent in the ongoing dry conditions.
The front will exit the region Sunday afternoon, and then a return to quiet conditions is expected for the remainder of the day and into the new work week. Conditions will be slightly cooler across the forecast area as we begin the week, with drier air and high pressure building into the Lower Mississippi River Valley. /19/EC/
