.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/
