.DISCUSSION...
Issued at 131 AM CDT Thu Sep 25 2025
A blocky upper level pattern is expected to redevelop across the
CONUS through the weekend resulting in another prolonged period of
dry weather and a return of above normal temperatures.
This morning, an upper low remains parked over the Great Lakes
with upper level troughing extending southwest across the mid
Mississippi Valley. At the surface, low pressure is over the Ohio
Valley with northwest flow in place in its wake across central
Illinois. The dry air mass in place over central Illinois coupled
with a strong inversion atop the mixed layer will keep the area
dry today. Temps will top out in the mid to upper 70s today under
mostly sunny skies, then will dip into the low to mid 50s tonight.
A few spots may even dip into the 40s under favorable radiational
cooling setup as surface ridge axis slowly sags south across
central Illinois.
Meanwhile, a strong shortwave "kicker" will dig across Hudson Bay
tonight into Friday and help to push the upper low further east. A
second wave taking a similar path over the weekend will be
followed by a strong and amplifying upper ridge. The ridge will
settle along the entirety of the Mississippi Valley late this
weekend and linger through much of the upcoming week as an Omega
block pattern redevelops. Temps will warm locally with highs back
into the mid and, at times, upper 80s Sunday through the first
half of the upcoming week. The ridge will also suppress convective
chances across the region resulting in another prolonged period
of dry weather that could exacerbate ongoing drought conditions.
