DISCUSSION

Issued at 253 PM CDT Sat Jun 20 2026

The forecast area is positioned within a northwest flow regime aloft, while also being situated in the active region between a pronounced subtropical ridge centered to our southwest and an unseasonably strong longwave trough over central and eastern CONUS.

Across the forecast area the earlier heavier rainfall has shifted east out of the area. Lingering light showers across the far eastern portions of warning area will continue pushing east/southeast, tapering off this afternoon into the evening as a very weak front crosses the region, leading to a mostly dry overnight period.

For Sunday(Happy Fathers Day), the subtropical ridge will once again impact the region, as the low level southerly flow increased heating will lead to disorganized showers heading into the morning and diurnally driven showers and isolated thunderstorms during the afternoon, with the highest rain chances focused on the areas north of the I-20 corridor. For areas south of the I-20 corridor, while possibilities are low a pop up shower wont be out of the question. /KP/

AVIATION

(18Z TAFS) Issued at 1220 PM CDT Sat Jun 20 2026

The combination of ongoing convection and low clouds across the region will continue to result in a mix of VFR/IFR flight categories at area TAF sites through the afternoon. Convection will come to an end heading into this evening, with a return to mainly VFR/MVFR categories into tonight. Low stratus developing toward day break Sunday, along with some isolated to scattered convection, will again result in a degradation of flight categories to MVFR/IFR status. Winds today will steadily become more southern in the wake of convection, and will become calm to light from the south overnight. /19/
