.DISCUSSION...
Issued at 140 PM CDT Sat Sep 6 2025
A blocking upper level ridge centered over the Intermountain West
this afternoon will very slowly translate east over the next week
resulting in a gradual warming trend locally along with a
continued stretch of primarily dry weather.
This afternoon, an expansive surface high is centered across the
Great Plains with ridging extending east into portions of the
lower Ohio Valley. Light northwest flow continues lee of the ridge
axis over central Illinois with temps running well below normal
(normal highs are lower/mid 80s) and dew points only in the 40s.
The surface high will inch east across central Illinois Sunday.
Winds will be slightly lighter, but otherwise expect a near carbon
copy of today`s weather with morning lows in the 40s and
afternoon highs in the low to mid 70s under mostly sunny skies.
Through the first half of the upcoming week, northwest flow aloft
across central Illinois will gradually shift to our east, replaced
by an amplified upper level ridge. A brief buckle in the ridge
could bring some precip to the region Tuesday, but chances are
better over the Upper Midwest with only a 10% chance locally.
Surface ridge axis will shift to New England, but with ridging
extending well to the southwest into the southern Great Plains.
This will cut off any notable moisture return from the Gulf and
dew points should continue to mix down into the 40s each afternoon
Monday and Tuesday.
Temps will gradually undergo a warming trend as the upper ridge
establishes itself over the Midwest through the first half of next
week. Highs in the mid 70s Monday will give way to low 80s Tuesday
followed by temps pushing near the 90 degree mark Wednesday and
Thursday.
