.DISCUSSION...
Issued at 208 PM CDT Sat Sep 27 2025
A broad and highly amplified ridge of high pressure looks to be the
main feature in control of central IL`s weather through at least the
next week, meaning little to no hope for rainfall. Even cloud cover
of any sort looks like it will be hard to come by. Temperatures
will continue to rise the next few days, with highs reaching the
upper 80s to around 90 Sunday through Tuesday, while lows generally
at least dip into the 50s. Normal highs are in the mid 70s, while
normal lows are around 50 this time of year. Lows will be closer to
normal given the dry conditions, clear skies, and light winds for
most of the period, allowing good radiational cooling at night.
An Atlantic tropical disturbance likely to become a tropical storm
within the next day now appears unlikely to have any impact in
this region, compared with a day ago when it appeared it could
have some impact on wind direction and cloud cover. Nevertheless,
a slight cooling looks on track for late next week as a cooler
northeast flow develops as a result of a strong Canadian high
positioning itself north of the Great Lakes.

.AVIATION...  (For the 18z TAFs through 18z Sunday Afternoon)
Issued at 1155 AM CDT Sat Sep 27 2025
A dry cold front approaching from the northwest will have little
impact on the central IL terminals as it stalls out north of the
area tonight. Cloud cover appears it will be negligible, while
light SW winds ahead of the front will weaken. All terminals
should see light and variable winds by shortly after 00Z,
continuing until close to 18Z Sunday.
