.DISCUSSION...
Issued at 227 PM CDT Fri Oct 10 2025
A cold front currently encroaching on the northwest CWA will
drift southeastward across the CWA through tonight. Cannot rule
out some sprinkles along the front, especially with a passing
upper-level trough this evening. A NNE wind shift behind the
front will then advect a band of lake effect clouds into
northwest Indiana and especially northeast Illinois late tonight
through much of Saturday. Low inversion heights under 5-6kft
will greatly limit precip potential, but marginal delta temps
and daytime diurnal enhancement could generate isolated light
lake effect rain showers or sprinkles over northeast Illinois
late morning into the afternoon.
The overall pattern across the central CONUS will remain
relatively quiet next week with low-amplitude ridge anchored
across the central CONUS. A trough tracking northeast to south-
central Canada will push a weakening cold front toward the
forecast area early in the week. A trailing mid-level front may
bring some decaying showers or sprinkles over the area Monday
afternoon and evening, but dry conditions are expected at this
time. A surface cold front will then shift southward over the
area Monday night and stall south of the forecast area by
Tuesday morning. Weak WAA and a mid-level disturbance rounding
the ridge may yield a period of light rain Tuesday night. The
central CONUS ridge will then amplify across the Mississippi
River Valley late in the week, likely resulting in dry and
seasonably warm conditions.

.AVIATION /06Z TAFS THROUGH 12Z SUNDAY/...
Issued at 1221 AM CDT Sat Oct 11 2025
There are no significant aviation weather concerns anticipated
through the period.
A surface cold front is current in the process of shifting
southward across the Chicago are terminals. In the wake of this
front, winds are shifting northerly (360-020 direction). Expect
winds to remain in this general direction through the remainder
of the night, before veering more northeasterly during the
daylight hours today. Speeds will be around 10 kt, particularly
during the daylight hours. Speeds will then ease below 10kt
this evening as direction transition more east-
southeasterly.
Cloud cover looks to increase across the Chicago area terminals
today as the flow shifts off the lake. Bases of this cloud cover
look to be low end VFR to near MVFR (basically in the 3,000-4,000
ft range). Any broken CIGs that result should then gradually
scatter out into this evening.
