.DISCUSSION... Issued at 241 AM CDT Fri Sep 12 2025
Mid-level ridging extends from Mexico into the Central Plains early this morning. Subtle perturbations rounding the apex of the ridge along with weak isentropic ascent have lead to the development of isolated to scattered showers overnight. This activity will wane through the morning and a dry, but hot day is expected. Breezy south winds will help to bump highs into the low/mid 90s with similar conditions on Saturday.
A longwave trough becomes negatively tilted as it ejects across the Plains Saturday night through Sunday night. The best dynamics remain north of the forecast area, but forcing is still progged to be strong enough for showers and storms to develop, especially Sunday evening/night. The severe weather potential appears low, but a few storms could produce gusty winds and small hail. Flow becomes southwesterly Monday and Tuesday with several perturbations passing through the mean flow. This leads to low chances for showers and storms, although confidence in timing and coverage of precipitation is low at this point. A stronger wave advances across the central CONUS by the middle of next week, bringing in additional chances for showers and storms along with cooler temperatures to end the week.
