.DISCUSSION...
Issued at 243 AM CDT Thu Jul 9 2026

Thursday through next Wednesday:

Thursday through Friday:

Sub-tropical ridging will remain over the region, continuing 
dangerous heat concerns for Thursday and Friday. Afternoon 
rainfall/convection will be possible along/east of I-55 Thursday 
then diminishing by Friday. A pattern change beginning Friday will 
bring rain chances through the rest of the extended forecast. 

Saturday through Wednesday:

A potent upper-lvl ridge will build and traverse over the Northern 
Plains, resulting in downstream troughing over the Mid-MS Valley. 
The trough will slowly push a frontal boundary towards the southeast 
through the weekend and into next week. As the boundary progress 
towards the area, rain chances (70-85%) will be greatest on Sunday 
and Monday. Rain will stick around through mid-week as the boundary 
gradually moves over the area. With the ongoing rain potential, heat 
relief is expected as heat indices drop below 105 degrees. /SW/

Issued at 619 AM CDT Thu Jul 9 2026

Overall, VFR flight categories will prevail at area TAF sites 
through this 12Z forecast. Isolated to scattered convection this 
afternoon and evening could result in a brief degradation of both 
ceilings and visibilities at sites where observed, mainly east of 
the Interstate 55 corridor, i.e. KGTR, KMEI, KPIB, & KHBG. Winds 
will increase from the southwest between 5-10 knots by late this 
morning, and continue as such through the afternoon hours. /19/
