ACUS48 KWNS 150808 SWOD48 SPC AC 150806 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0306 AM CDT Mon Sep 15 2025 Valid 181200Z - 231200Z ...DISCUSSION... An upper low/shortwave trough will persist over the north-central U.S. for much of the period. This system is not forecast to deepen, resulting in little surface cyclogenesis, with mainly weak surface troughing persisting over the Plains. Southerly low-level flow will maintain a seasonally moist airmass, and periods of showers and thunderstorms are expected each day across parts of the Plains to the MS Valley. Modest vertical shear and airmass modification from daily rounds of convection will likely limit overall severe potential. Medium range guidance suggests by late in the period, around Day 8/Mon, a stronger surface cold front may sweep across portions of the Plains as a deepening, more progressive upper trough moves from the Rockies into the Plains. ..Leitman.. 09/15/2025 |
