DISCUSSION

Issued at 215 AM CDT Sat Sep 26 2026

Dry and cool surface high pressure will be the rule over the Quad State through Monday, while a skinny ridge aloft lingers overhead. However, mid-level energy may sneak through the ridge and bring some sprinkles into southern Illinois this morning, and again tonight into early Sunday over the western half of the region.

South winds will return Tuesday as an upper trough pushes east through the northern Plains and Upper Midwest. This will flatten the upper ridge, resulting in southwest flow aloft for the remainder of the work week. The south winds at the surface will allow temperatures to climb above normal Wednesday through at least Friday.

A closed upper low over AZ/NM Wednesday will weaken and become positively-tilted as it moves east toward the Quad State in the wake of the northern stream system. 20-40% chances of showers enter the forecast Wednesday, mainly over southeast Missouri and southern Illinois. With time, those chances will spread over the entire region Thursday into Friday. At this time, instability appears very limited (<500J/kg), so thunderstorms should not be prevalent, but the NBM does have some slight chances of thunder in the afternoon over southeast Missouri Thursday and Friday. No severe weather or heavy rainfall is expected at this time.

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/

Issued at 1046 PM CDT Fri Sep 25 2026

Northeast winds are funneling drier air into the region, which combined with increasing mid cloud should reduce the risk for widespread fog overnight. However, some shallow ground fog can't be completely ruled out. Increasing mid cloud overnight will carry over through the day on Saturday. A few sprinkles are possible, but that should be about it. Northeast winds are expected to persist tomorrow with VFR conditions expected.
