.DISCUSSION...
Issued at 212 PM CDT Sat Oct 24 2026

18z/1pm surface analysis shows a sprawling ridge of high
pressure from Quebec to the Gulf Coast. Meanwhile a 992mb low
is tracking across northern Manitoba with its trailing cold
front extending southward into the Plains. Despite high clouds
streaming across the region from the northwest, partial
sunshine has heated the dry airmass quite efficiently this
afternoon...resulting in current temperatures in the lower to
middle 70s. As has been the case for the past several days,
readings will quickly drop after sunset...with overnight lows
ranging from the lower to middle 40s in the Wabash River Valley
to around 50 degrees along/west of the Illinois River.

The Manitoba low will continue to track eastward over the next
24 hours, gradually pulling the cold front southward toward
Illinois. However as the boundary becomes parallel with the
upper flow, it will lose its southward momentum and remain well
W/NW of the KILX CWA. As a result, the stretch of very warm and
dry weather will continue through the middle of next week as
highs routinely climb into the middle to upper 70s while
overnight lows drop into the upper 40s and lower 50s.

A second short-wave trough and its associated surface low
traversing southern Canada will push another cold front
southward toward the region by the end of the week. With all 12z
Oct 24 models showing a slight weakening of the upper ridge, it
appears this boundary will drop a bit further south than the
first. With GFS precipitable water values edging up to 1.25-1.50
immediately along/ahead of the approaching front, have added 20
PoPs for showers to the forecast Thursday and Thursday night
along/north of a Macomb to Minonk line. The front will gradually
dissipate and/or lift back northward on Friday, resulting in a
return to warm/dry conditions across the board.
