.DISCUSSION...
Issued at 208 PM EST Mon Nov 17 2025

A quick moving system will move from the Midwest into the Great
Lakes region tonight into Tuesday. Initially starting as mainly
rain showers a frontogenesis band associated with the system
will allow a quick change over from rain showers to a rain/snow
mix and ultimately all snow for areas north of US-30 with even
some minor accumulations, 1 inch or less, mainly north of US-6
along and east of I-69. For our far northeast parts of the CWA
there is a low chance of some freezing rain on the onset but
with ground temperatures still fairly warm and any freezing rain
occurrence being very brief did opt to leave out of the
forecast grids but did want to mention here as there is a
chance.

A zonal flow aloft on Wednesday and Thursday will allow for
some slight synoptic warming with highs by Thursday getting into
the 50s across the area. By Friday another system this time
slightly warmer than tonights system originating from the Texas
Panhandle will bring another chance of rainfall beginning
Thursday night through Saturday. Looking to see a little bit
more rainfall with this system as being centered further south
will have access to a bit more moisture to work with. Highs
Friday through Sunday will range in the upper 40s to mid 50s.
Fairly close to seasonal norms.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1257 PM EST Mon Nov 17 2025

High pressure across the region this aftn will slowly push east
overnight while a low pressure system over the central plains
moves into Missouri by Tue morning. Clouds will increase later
today ahead of the previously mentioned low pressure. Warm air
advection after sunset will spout showers across IL that will
eventually spread east into IN. In agreement with the previous
forecast of introducing precip after 06Z. Model solutions
continue to reflect a window of 09-10Z fore precip becoming
predominant.

Forecast soundings continue to favor rain at KFWA, while mostly
rain at KSBN with a brief period of possible -RASN. Will keep
the rain solution as previously forecast and allow for later
shifts to fine tune the forecast for Tuesday morning at KSBN.
