.DISCUSSION...(through next Sunday)
Issued at 1248 AM CDT Sun Sep 7 2025

High pressure over the Midwest will bring dry and relatively cool
weather through Monday. Temperatures will reach the low 70s
today, rising to the mid 70s by Monday as high pressure departs
and winds shift southerly. The warming trend will continue through
mid-week, with a subtle shortwave trough moving over the
Mississippi Valley on Tuesday and mid-level heights steadily
increasing Wednesday through Friday. Temperatures are expected to
reach the mid 80s on Wednesday, with upper 80s likely from
Thursday through Sunday. As the ridge axis builds over central
Illinois this weekend and 850mb temperatures approach 20 C, some
locations may reach 90 F.

While dry and 90 is the base case for next weekend, it`s worth
noting that the past couple runs of the deterministic ECMWF have
shown a tendency to break down the blocking pattern and send an
upper- level low equatorward into the Great Lakes. It`s an outlier
right now, but if the broader guidance trends more toward this
solution it could thwart the dry and 90 narrative for next
weekend.
